Prefectures of France
–
There are 101 prefectures in France, one for each department. The official in charge is the prefect, the prefect represents the national government at the local level and as such exercises the powers that are constitutionally attributed to the national government. The prefect issues ordinances written for the application of law, to close a building that does not conform to safety codes. In the past, the prefect was head of the department, but since 1982, there is an exception in Paris and its three surrounding departments. These departments are administered by a prefecture for law enforcement and security purposes, called the Prefecture of Police. The power of law enforcement is usually invested in the mayor in other French communes, the departments are divided into arrondissements, themselves divided into cantons. The chef-lieu darrondissement is the subprefecture, the official in charge is the subprefect (French, sous-préfet. Cantons have relatively few competences, the most important one being the local organisation of elections, administrative divisions of France French National Police

Communes of France
–
The commune is a level of administrative division in the French Republic. French communes are roughly equivalent to civil townships incorporated municipalities in the United States or Gemeinden in Germany, the United Kingdom has no exact equivalent, as communes resemble districts in urban areas, but are closer to parishes in rural areas where districts are much larger. Communes are based on historical geographic communities or villages and have received significant powers of governance to manage the populations, the communes are the fourth-level administrative divisions of France. A French commune may be a city of 2.2 million inhabitants like Paris, communes typically are based on pre-existing villages and facilitate local governance. All communes have names, but not all named geographic areas or groups of people residing together are communes, a commune is a town, city, or municipality. Use of commune in English is a habit, and one that might be corrected. There is nothing in commune in French that is different from town in English. The French word commune appeared in the 12th century, from Medieval Latin communia, as of January 2015, there were 36,681 communes in France,36,552 of them in metropolitan France and 129 of them overseas. This is a higher total than that of any other European country. The whole territory of the French Republic is divided into communes and this is unlike some other countries, such as the United States, where unincorporated areas directly governed by a county or a higher authority can be found. There are only a few exceptions, COM of Saint-Martin and it was previously a commune inside the Guadeloupe région. The commune structure was abolished when Saint-Martin became an overseas collectivity on 22 February 2007, COM of Wallis and Futuna, which still is divided according to the three traditional chiefdoms. It was previously a commune inside the Guadeloupe region, the commune structure was abolished when Saint-Barthélemy became an overseas collectivity on 22 February 2007.88 square kilometres. The median area of metropolitan Frances communes at the 1999 census was even smaller, the median area is a better measure of the area of a typical French commune. This median area is smaller than that of most European countries. In Italy, the area of communes is 22 km2, in Belgium it is 40 km2, in Spain it is 35 km2, and in Germany. Switzerland and the Länder of Rhineland-Palatinate, Schleswig-Holstein, and Thuringia in Germany were the places in Europe where the communes had a smaller median area than in France. The communes of Frances overseas départements such as Réunion and French Guiana are large by French standards and they usually group into the same commune several villages or towns, often with sizeable distances among them

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

France
–
France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

Regions of France
–
France is divided into 18 administrative regions, including 13 metropolitan regions and 5 overseas regions. The current legal concept of region was adopted in 1982, the term région was officially created by the Law of Decentralisation, which also gave regions their legal status. The first direct elections for representatives took place on 16 March 1986. In 2016, the number of regions was reduced from 27 to 18 through amalgamation, in 2014, the French parliament passed a law reducing the number of metropolitan regions from 22 to 13 with effect from 1 January 2016. However, the region of Upper and Lower Normandy is simply called Normandy. Permanent names were to be proposed by the new regional councils by 1 July 2016, the legislation defining the new regions also allowed the Centre region to officially change its name to Centre-Val de Loire with effect from January 2015. Two regions, Auvergne-Rhône-Alpes and Bourgogne-Franche-Comté, opted to retain their interim names, between 1982 and 2015, there were 22 regions in Metropolitan France. Before 2011, there were four regions, in 2011 Mayotte became the fifth. Regions lack separate legislative authority and therefore cannot write their own statutory law and they levy their own taxes and, in return, receive a decreasing part of their budget from the central government, which gives them a portion of the taxes it levies. They also have considerable budgets managed by a council made up of representatives voted into office in regional elections. A regions primary responsibility is to build and furnish high schools, in March 2004, the French central government unveiled a controversial plan to transfer regulation of certain categories of non-teaching school staff to the regional authorities. Critics of this plan contended that tax revenue was insufficient to pay for the costs. In addition, regions have considerable power over infrastructural spending, e. g. education, public transit, universities and research. This has meant that the heads of regions such as Île-de-France or Rhône-Alpes can be high-profile positions. Number of regions controlled by each coalition since 1986, Overseas region is a recent designation, given to the overseas departments that have similar powers to those of the regions of metropolitan France.

Normandy
–
Normandy is one of the regions of France, roughly corresponding to the historical Duchy of Normandy. Administratively, Normandy is divided into five departments, Calvados, Eure, Manche, Orne and it covers 30,627 km², forming roughly 5% of the territory of France. Its population of 3.37 million accounts for around 5% of the population of France, Normans is the name given to the inhabitants of Normandy, and the region is the homeland of the Norman language. The historical region of Normandy comprised the region of Normandy, as well as small areas now part of the départements, or departments of Mayenne. For a century and a following the Norman conquest of England in 1066, Normandy and England were linked by Norman. Archaeological finds, such as paintings, prove that humans were present in the region in prehistoric times. Celts invaded Normandy in successive waves from the 4th to the 3rd century BC, when Julius Caesar invaded Gaul, there were nine different Celtic tribes living in Normandy. The Romanisation of Normandy was achieved by the methods, Roman roads. Classicists have knowledge of many Gallo-Roman villas in Normandy, in the late 3rd century, barbarian raids devastated Normandy. Coastal settlements were raided by Saxon pirates, Christianity also began to enter the area during this period. In 406, Germanic tribes began invading from the east, while the Saxons subjugated the Norman coast, the Roman Emperor withdrew from most of Normandy. As early as 487, the area between the River Somme and the River Loire came under the control of the Frankish lord Clovis, the Vikings started to raid the Seine Valley during the middle of the 9th century. As early as 841, a Viking fleet appeared at the mouth of the Seine, after attacking and destroying monasteries, including one at Jumièges, they took advantage of the power vacuum created by the disintegration of Charlemagnes empire to take northern France. The fiefdom of Normandy was created for the Norwegian Viking leader Hrólfr Ragnvaldsson, Rollo had besieged Paris but in 911 entered vassalage to the king of the West Franks, Charles the Simple, through the Treaty of Saint-Clair-sur-Epte. In exchange for his homage and fealty, Rollo legally gained the territory which he, the name Normandy reflects Rollos Viking origins. The descendants of Rollo and his followers adopted the local Gallo-Romance language and they became the Normans – a Norman-speaking mixture of Saxons and indigenous Franks and Celts. Besides the Norman conquest of England and the subsequent conquests of Wales and Ireland, Norman families, such as that of Tancred of Hauteville, Rainulf Drengot and Guimond de Moulins played important parts in the Norman conquest of southern Italy and Crusades. They also carved out a place for themselves and their descendants in the Crusader states of Asia Minor, the 14th century Norman explorer Jean de Béthencourt established a kingdom in the Canary Islands

Departments of France
–
In the administrative divisions of France, the department is one of the three levels of government below the national level, between the administrative regions and the commune. There are 96 departments in metropolitan France and 5 overseas departments, each department is administered by an elected body called a departmental council. From 1800 to April 2015, they were called general councils, the departments were created in 1791 as a rational replacement of Ancien Régime provinces with a view to strengthen national unity, the title department is used to mean a part of a larger whole. Almost all of them were named after geographical features rather than after historical or cultural territories which could have their own loyalties. The earliest known suggestion of it is from 1764 in the writings of dArgenson and they have inspired similar divisions in many countries, some of them former French colonies. Most French departments are assigned a number, the Official Geographical Code. Some overseas departments have a three-digit number, the number is used, for example, in the postal code, and was until recently used for all vehicle registration plates. For example, inhabitants of Loiret might refer to their department as the 45 and this reform project has since been abandoned. The first French territorial departments were proposed in 1665 by Marc-René dArgenson to serve as administrative areas purely for the Ponts et Chaussées infrastructure administration, before the French Revolution, France gained territory gradually through the annexation of a mosaic of independent entities. By the close of the Ancien Régime, it was organised into provinces, during the period of the Revolution, these were dissolved, partly in order to weaken old loyalties. Their boundaries served two purposes, Boundaries were chosen to break up Frances historical regions in an attempt to erase cultural differences, Boundaries were set so that every settlement in the country was within a days ride of the capital of the department. This was a security measure, intended to keep the national territory under close control. This measure was directly inspired by the Great Terror, during which the government had lost control of rural areas far from any centre of government. The old nomenclature was carefully avoided in naming the new departments, most were named after an areas principal river or other physical features. Even Paris was in the department of Seine, the number of departments, initially 83, was increased to 130 by 1809 with the territorial gains of the Republic and of the First French Empire. Following Napoleons defeats in 1814-1815, the Congress of Vienna returned France to its pre-war size, in 1860, France acquired the County of Nice and Savoy, which led to the creation of three new departments. Two were added from the new Savoyard territory, while the department of Alpes-Maritimes was created from Nice, the 89 departments were given numbers based on their alphabetical order. The department of Bas-Rhin and parts of Meurthe, Moselle, Vosges and Haut-Rhin were ceded to the German Empire in 1871, following Frances defeat in the Franco-Prussian War

Orne
–
Orne is a department in the northwest of France, named after the river Orne. Orne is one of the original 83 departments created during the French Revolution, on 4 March 1790 and it was created from parts of the former provinces of Normandy and Perche. Orne is in the region of Normandy neighbouring Eure, Eure-et-Loir, Sarthe, Manche, Mayenne and it is the only department of Normandy to be landlocked. The largest town by a margin is the prefecture, Alençon which is an administrative. There are no industrial centres, agriculture remains the economic focus of Orne. The inhabitants of the department are called Ornais, the recorded population level peaked at 443,688 in 1836. Once motor car ownership started to surge in the 1960s employment opportunities became less restricted, the two major cities in the Orne are Alençon, the prefecture, and Flers. Alençon is the town of the Orne department. Camembert, the village where Camembert cheese is made, is located in Orne, the local dialect is known as Augeron

Daylight saving time
–
Daylight saving time is the practice of advancing clocks during summer months by one hour so that evening daylight lasts an hour longer, while sacrificing normal sunrise times. Typically, regions that use Daylight Savings Time adjust clocks forward one hour close to the start of spring, American inventor and politician Benjamin Franklin proposed a form of daylight time in 1784. New Zealander George Hudson proposed the idea of saving in 1895. The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30,1916, many countries have used it at various times since then, particularly since the energy crisis of the 1970s. The practice has both advocates and critics, DST clock shifts sometimes complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns. Computer software often adjusts clocks automatically, but policy changes by various jurisdictions of DST dates, industrialized societies generally follow a clock-based schedule for daily activities that do not change throughout the course of the year. The time of day that individuals begin and end work or school, North and south of the tropics daylight lasts longer in summer and shorter in winter, with the effect becoming greater as one moves away from the tropics. However, they will have one hour of daylight at the start of each day. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, DST is also of little use for locations near the equator, because these regions see only a small variation in daylight in the course of the year. After ancient times, equal-length civil hours eventually supplanted unequal, so civil time no longer varies by season, unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies. This 1784 satire proposed taxing window shutters, rationing candles, and waking the public by ringing church bells, despite common misconception, Franklin did not actually propose DST, 18th-century Europe did not even keep precise schedules. However, this changed as rail transport and communication networks came to require a standardization of time unknown in Franklins day. Modern DST was first proposed by the New Zealand entomologist George Hudson, whose shift work job gave him time to collect insects. An avid golfer, he also disliked cutting short his round at dusk and his solution was to advance the clock during the summer months, a proposal he published two years later. The proposal was taken up by the Liberal Member of Parliament Robert Pearce, a select committee was set up to examine the issue, but Pearces bill did not become law, and several other bills failed in the following years. Willett lobbied for the proposal in the UK until his death in 1915, william Sword Frost, mayor of Orillia, Ontario, introduced daylight saving time in the municipality during his tenure from 1911 to 1912. Starting on April 30,1916, the German Empire and its World War I ally Austria-Hungary were the first to use DST as a way to conserve coal during wartime, Britain, most of its allies, and many European neutrals soon followed suit. Russia and a few other countries waited until the year

Maine (province of France)
–
Maine is one of the traditional provinces of France. It corresponds to the former County of Maine, whose capital was also the city of Le Mans, the area, now divided into the departments of Sarthe and Mayenne, contains about 857,000 inhabitants. In the 8th and 9th centuries there existed a Duchy of Normandy and this duchy was a march that may have included several counties including Maine, and extended into Lower Normandy, all the way to the Seine. In 748, Pepin the Short, then Mayor of the Palace and thus the most powerful man in France after the king, in 790 Charlemagne in turn gave it to his younger son, Charles the Younger. Charlemagnes grandson, the future Charles the Bald, and his son Louis the Stammerer inherited the title, ragenold, who may have been the son of Renaud dHerbauges, died in 885 fighting the Vikings who were pillaging Rouen. The son-in-law of Charlemagne, Rorgon, was the count of Maine between 832 and 839, in the last half of the 9th century, Maine took on strategic importance because of invasions from Normandy and Brittany. Rorgons son Gauzfrid in turn became Count of Maine and he fought against Salomon, King of Brittany and in 866 participated in the battle of Brissarthe alongside Robert the Strong, the Frankish Margave of Neustria. In 924 King Rudolph of France was said to give Maine to the Norse nobleman Rollo, bordering the county of Anjou to the south and the Duchy of Normandy to the north, Maine became a bone of contention between the rulers of these more powerful principalities. Hugh III of Maine was forced to recognize Fulk III, Count of Anjou as his overlord, sometime between 1045 and 1047 Hugh IV married Bertha, daughter of Odo II, Count of Blois and widow of Alan III, Duke of Brittany. The Angevins did not want Maine to come under the influence of Blois, but the Normans did not want Maine to return to the Angevin orbit, so were pulled into the conflict. The precise chronology is disputed, but it is clear that in 1051 Hugh IV died, Anjou wound up with effective control of most of the county, but the Normans did take several important strongholds on the Maine–Normandy border. Hugh IVs son Herbert II fled to the Norman court and his death in 1062 precipitated a succession crisis, Herbert died childless in 1062 after declaring William the Bastard, then Duke of Normandy, his heir. His sister Marguerite was engaged to Williams eldest son, Robert Curthose and Herbert had taken refuge at Williams court in 1056 when Geoffrey Martel, Duke of Anjou, while the county was in Angevin hands, Anjou had its own succession problem. Duke William of Normandy claimed the county on their behalf of Herberts young sister Margaret, the other claimant was Herberts aunt Biota, a sister of Hugh IV, and her husband Walter, Count of the Vexin. Biota and Walter were captured at the taking of Le Mans and they died sometime later in 1063, poisoned, it was rumoured, though there is no hard evidence for this. Norman control of Maine secured the border of Normandy against Anjou and is one factor which enabled William to launch his successful invasion of England in 1066. In 1069 the citizens of Le Mans revolted against the Normans, soon some of the Manceaux barons joined the revolt, the Normans were expelled in 1070, and young Hugh V was proclaimed Count of Maine. He was the son of Azzo dEste and his wife Gersendis, Azzo returned to Italy, leaving Gersendis in charge

William the Conqueror
–
William I, usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. A descendant of Rollo, he was Duke of Normandy from 1035 onward, after a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England six years later. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands, William was the son of the unmarried Robert I, Duke of Normandy, by Roberts mistress Herleva. His illegitimate status and his youth caused some difficulties for him after he succeeded his father, during his childhood and adolescence, members of the Norman aristocracy battled each other, both for control of the child duke and for their own ends. In 1047 William was able to quash a rebellion and begin to establish his authority over the duchy and his marriage in the 1050s to Matilda of Flanders provided him with a powerful ally in the neighbouring county of Flanders. By the time of his marriage, William was able to arrange the appointments of his supporters as bishops and his consolidation of power allowed him to expand his horizons, and by 1062 William was able to secure control of the neighbouring county of Maine. In the 1050s and early 1060s William became a contender for the throne of England, then held by the childless Edward the Confessor, his first cousin once removed. There were other claimants, including the powerful English earl Harold Godwinson. William argued that Edward had previously promised the throne to him, William built a large fleet and invaded England in September 1066, decisively defeating and killing Harold at the Battle of Hastings on 14 October 1066. After further military efforts William was crowned king on Christmas Day 1066 and he made arrangements for the governance of England in early 1067 before returning to Normandy. Several unsuccessful rebellions followed, but by 1075 Williams hold on England was mostly secure, Williams final years were marked by difficulties in his continental domains, troubles with his eldest son, and threatened invasions of England by the Danes. In 1086 William ordered the compilation of the Domesday Book, a listing all the landholders in England along with their holdings. William died in September 1087 while leading a campaign in northern France and his reign in England was marked by the construction of castles, the settling of a new Norman nobility on the land, and change in the composition of the English clergy. He did not try to integrate his various domains into one empire, Williams lands were divided after his death, Normandy went to his eldest son, Robert Curthose, and his second surviving son, William Rufus, received England. Norsemen first began raiding in what became Normandy in the late 8th century, permanent Scandinavian settlement occurred before 911, when Rollo, one of the Viking leaders, and King Charles the Simple of France reached an agreement surrendering the county of Rouen to Rollo. The lands around Rouen became the core of the duchy of Normandy. Normandy may have used as a base when Scandinavian attacks on England were renewed at the end of the 10th century. In an effort to improve matters, King Æthelred the Unready took Emma of Normandy, sister of Duke Richard II, as his second wife in 1002

Siege
–
A siege is a military blockade of a city or fortress with the intent of conquering by attrition or assault. This derives from sedere, Latin for to sit, Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static defensive position. Consequently, an opportunity for negotiation between combatants is not uncommon, as proximity and fluctuating advantage can encourage diplomacy, a siege occurs when an attacker encounters a city or fortress that cannot be easily taken by direct assault and refuses to surrender. Failing a military outcome, sieges can often be decided by starvation, thirst, or disease and this form of siege, though, can take many months or even years, depending upon the size of the stores of food the fortified position holds. During the process of circumvallation, the force can be set upon by another force of enemies due to the lengthy amount of time required to starve a position. During the Warring States era of ancient China, there is textual and archaeological evidence of prolonged sieges and siege machinery used against the defenders of city walls. Siege machinery was also a tradition of the ancient Greco-Roman world, during the Renaissance and the early modern period, siege warfare dominated the conduct of war in Europe. Leonardo da Vinci gained as much of his renown from the design of fortifications as from his artwork, Medieval campaigns were generally designed around a succession of sieges. In the Napoleonic era, increasing use of more powerful cannon reduced the value of fortifications. In the 20th century, the significance of the classical siege declined, with the advent of mobile warfare, a single fortified stronghold is no longer as decisive as it once was. Modern sieges are more commonly the result of smaller hostage, militant, the Assyrians deployed large labour forces to build new palaces, temples, and defensive walls. Some settlements in the Indus Valley Civilization were also fortified, by about 3500 BC, hundreds of small farming villages dotted the Indus River floodplain. Many of these settlements had fortifications and planned streets, mundigak in present-day south-east Afghanistan has defensive walls and square bastions of sun-dried bricks. City walls and fortifications were essential for the defence of the first cities in the ancient Near East, the walls were built of mudbricks, stone, wood, or a combination of these materials, depending on local availability. They may also have served the purpose of showing presumptive enemies the might of the kingdom. The great walls surrounding the Sumerian city of Uruk gained a widespread reputation, the walls were 9.5 km in length, and up to 12 m in height. Later, the walls of Babylon, reinforced by towers, moats, in Anatolia, the Hittites built massive stone walls around their cities atop hillsides, taking advantage of the terrain. In Shang Dynasty China, at the site of Ao, large walls were erected in the 15th century BC that had dimensions of 20 m in width at the base and enclosed an area of some 2,100 yards squared

County of Anjou
–
The Count of Anjou was the ruler of the county of Anjou, first granted by Charles the Bald in the 9th century to Robert the Strong. Ingelger and his son were viscounts of Angers until Ingelgers son Fulk the Red assumed the title of Count of Anjou, Ingelgers male line ended with Geoffrey II, Count of Anjou. Subsequent counts of Anjou were descended from Geoffreys sister Ermengarde of Anjou and Geoffrey II and their agnatic descendants, who included the Angevin kings of England, continued to hold these titles and property until the French monarchy gained control of the area. Thereafter the titles Count of Anjou and, after 1360, Duke of Anjou were granted several times, usually to members of the French ruling houses of Valois and Bourbon. The title was held by Philippe, a grandson of King Louis XIV, since then, some Spanish legitimist claimants to the French throne have borne the title even to the present day, as does a nephew of the Orléanist pretender. In 1204, Anjou was lost to king Philip II of France and it was re-granted as an appanage for Louis VIIIs son John, who died in 1232 at the age of thirteen, and then to Louiss youngest son, Charles, later the first Angevin king of Sicily. In 1290, Margaret married Charles of Valois, the brother of king Philip IV of France. He became Count of Anjou in her right, in 1328, Philip of Valois ascended the French throne and became King Philip VI. At this time, the counties of Anjou, Maine, on 26 April 1332, Philip granted the county to his eldest son, John, Following Johns ascension to the throne as John II in 1350, the title once again reverted to the royal domain. The dukes contributed greatly to social reform in the 1300s and 1400s, on the death of Charles IV, Anjou returned to the royal domain. After the death of Henry, Count of Chambord, only the descendants of Philip V of Spain remained of the line of Louis XIV. The most senior of these, the Carlist claimant to the Spanish throne, some of them used the courtesy title of Duke of Anjou. At the death of Alfonso Carlos in 1936, the Capetian seniority passed to the exiled King of Spain, Alfonso XIII. In 1941, Infante Jaime, Duke of Segovia, succeeded his father Alfonso XIII as the male of Louis XIV. He then adopted the title of Duke of Anjou, on December 8,2004, Henry, Count of Paris, Duke of France, Orléanist Pretender to the French throne, granted his nephew Charles Philippe the title of Duke of Anjou. For him, the title was available since 1824, because he doesnt recognize his cousins courtesy title, list of Countesses and Duchesses of Anjou Anjou Titles of the counts and dukes of Anjou in the 11-16th centuries from contemporary documents with bibliography

French Revolution
–
Through the Revolutionary Wars, it unleashed a wave of global conflicts that extended from the Caribbean to the Middle East. Historians widely regard the Revolution as one of the most important events in human history, the causes of the French Revolution are complex and are still debated among historians. Following the Seven Years War and the American Revolutionary War, the French government was deeply in debt, Years of bad harvests leading up to the Revolution also inflamed popular resentment of the privileges enjoyed by the clergy and the aristocracy. Demands for change were formulated in terms of Enlightenment ideals and contributed to the convocation of the Estates-General in May 1789, a central event of the first stage, in August 1789, was the abolition of feudalism and the old rules and privileges left over from the Ancien Régime. The next few years featured political struggles between various liberal assemblies and right-wing supporters of the intent on thwarting major reforms. The Republic was proclaimed in September 1792 after the French victory at Valmy, in a momentous event that led to international condemnation, Louis XVI was executed in January 1793. External threats closely shaped the course of the Revolution, internally, popular agitation radicalised the Revolution significantly, culminating in the rise of Maximilien Robespierre and the Jacobins. Large numbers of civilians were executed by revolutionary tribunals during the Terror, after the Thermidorian Reaction, an executive council known as the Directory assumed control of the French state in 1795. The rule of the Directory was characterised by suspended elections, debt repudiations, financial instability, persecutions against the Catholic clergy, dogged by charges of corruption, the Directory collapsed in a coup led by Napoleon Bonaparte in 1799. The modern era has unfolded in the shadow of the French Revolution, almost all future revolutionary movements looked back to the Revolution as their predecessor. The values and institutions of the Revolution dominate French politics to this day, the French Revolution differed from other revolutions in being not merely national, for it aimed at benefiting all humanity. Globally, the Revolution accelerated the rise of republics and democracies and it became the focal point for the development of all modern political ideologies, leading to the spread of liberalism, radicalism, nationalism, socialism, feminism, and secularism, among many others. The Revolution also witnessed the birth of total war by organising the resources of France, historians have pointed to many events and factors within the Ancien Régime that led to the Revolution. Over the course of the 18th century, there emerged what the philosopher Jürgen Habermas called the idea of the sphere in France. A perfect example would be the Palace of Versailles which was meant to overwhelm the senses of the visitor and convince one of the greatness of the French state and Louis XIV. Starting in the early 18th century saw the appearance of the sphere which was critical in that both sides were active. In France, the emergence of the public sphere outside of the control of the saw the shift from Versailles to Paris as the cultural capital of France. In the 1750s, during the querelle des bouffons over the question of the quality of Italian vs, in 1782, Louis-Sébastien Mercier wrote, The word court no longer inspires awe amongst us as in the time of Louis XIV

Printing
–
Printing is a process for reproducing text and images using a master form or template. The earliest examples include Cylinder seals and other such as the Cyrus Cylinder. The earliest known form of printing came from China dating to before 220 A. D. Later developments in printing include the type, first developed by Bi Sheng in China around 1040 AD. Johannes Gutenberg introduced mechanical movable type printing to Europe in the 15th century, modern large-scale printing is typically done using a printing press, while small-scale printing is done free-form with a digital printer. Though paper is the most common material, it is frequently done on metals, plastics, cloth. On paper it is carried out as a large-scale industrial process and is an essential part of publishing. Woodblock printing is a technique for printing text, images or patterns that was used widely throughout East Asia and it originated in China in antiquity as a method of printing on textiles and later on paper. As a method of printing on cloth, the earliest surviving examples from China date to before 220 A. D, the earliest surviving woodblock printed fragments are from China. They are of silk printed with flowers in three colours from the Han Dynasty and they are the earliest example of woodblock printing on paper appeared in the mid-seventh century in China. By the ninth century, printing on paper had taken off, by the tenth century,400,000 copies of some sutras and pictures were printed, and the Confucian classics were in print. A skilled printer could print up to 2,000 double-page sheets per day, Printing spread early to Korea and Japan, which also used Chinese logograms, but the technique was also used in Turpan and Vietnam using a number of other scripts. This technique then spread to Persia and Russia and this technique was transmitted to Europe via the Islamic world, and by around 1400 was being used on paper for old master prints and playing cards. However, Arabs never used this to print the Quran because of the limits imposed by Islamic doctrine, block printing, called tarsh in Arabic developed in Arabic Egypt during the ninth-tenth centuries, mostly for prayers and amulets. There is some evidence to suggest that these print blocks made from non-wood materials, possibly tin, lead, the techniques employed are uncertain, however, and they appear to have had very little influence outside of the Muslim world. Though Europe adopted woodblock printing from the Muslim world, initially for fabric, block printing later went out of use in Islamic Central Asia after movable type printing was introduced from China. Block printing first came to Europe as a method for printing on cloth, images printed on cloth for religious purposes could be quite large and elaborate. When paper became relatively easily available, around 1400, the medium transferred very quickly to small religious images

Wehrmacht
–
The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the Heer, the Kriegsmarine and the Luftwaffe, after the Nazi seizure of power in 1933, one of Adolf Hitler’s most overt and audacious moves was to establish the Wehrmacht, a modern armed forces fully capable of offensive use. In December 1941, Hitler designated himself as commander-in-chief of the Wehrmacht, the Wehrmacht formed the heart of Germany’s politico-military power. In the early part of World War II, Hitlers generals employed the Wehrmacht through innovative combined arms tactics to devastating effect in what was called a Blitzkrieg, the Wehrmachts new military structure, unique combat techniques, newly developed weapons, and unprecedented speed and brutality crushed their opponents. Closely cooperating with the SS, the German armed forces committed war crimes and atrocities. By the time the war ended in Europe in May 1945, only a few of the Wehrmacht’s upper leadership were tried for war crimes, despite evidence suggesting that more were involved in illegal actions. The German term Wehrmacht generically describes any nations armed forces, for example, the Frankfurt Constitution of 1848 designated all German military forces as the German Wehrmacht, consisting of the Seemacht and the Landmacht. In 1919, the term Wehrmacht also appears in Article 47 of the Weimar Constitution, establishing that, from 1919, Germanys national defense force was known as the Reichswehr, a name that was dropped in favor of Wehrmacht on 21 May 1935. In January 1919, after World War I ended with the signing of the armistice of 11 November 1918, in March 1919, the national assembly passed a law founding a 420, 000-strong preliminary army, the Vorläufige Reichswehr. The terms of the Treaty of Versailles were announced in May, the army was limited to one hundred thousand men with an additional fifteen thousand in the navy. The fleet was to consist of at most six battleships, six cruisers, submarines, tanks and heavy artillery were forbidden and the air-force was dissolved. A new post-war military, the Reichswehr, was established on 23 March 1921, General conscription was abolished under another mandate of the Versailles treaty. The Reichswehr was limited to 115,000 men, and thus the armed forces, under the leadership of Hans von Seeckt, though Seeckt retired in 1926, the army that went to war in 1939 was largely his creation. Germany was forbidden to have an air-force by the Versailles treaty, nonetheless and these officers saw the role of an air-force as winning air-superiority, tactical and strategic bombing and providing ground support. That the Luftwaffe did not develop a strategic bombing force in the 1930s was not due to a lack of interest, but because of economic limitations. The leadership of the Navy led by Grand Admiral Erich Raeder, officers who believed in submarine warfare led by Admiral Karl Dönitz were in a minority before 1939. By 1922, Germany had begun covertly circumventing the conditions of the Versailles Treaty, a secret collaboration with the Soviet Union began after the treaty of Rapallo. Major-General Otto Hasse traveled to Moscow in 1923 to further negotiate the terms, Germany helped the Soviet Union with industrialization and Soviet officers were to be trained in Germany

French Army

The French Army, officially the Land Army is the land-based and largest component of the French Armed Forces. Along with the French Air Force, the French Navy and the National Gendarmerie, the current Chief of Staff of the French Army is General Jean-Pierre Bosser, a direct subordinate of the Chief of the Defence Staff. All soldiers are considered professionals following the suspension of conscription, voted in parliament in 1997, as of 2014, the French Army employed 111,628 personnel. In addition, the element of the French Army consisted of 15,453 personnel of the Operational Reserve. The Kings of France needed reliable troops during and after the Hundred Years War and these units of troops were raised by issuing ordonnances to govern their length of service, composition and payment. These Compagnies dordonnance formed the core of the Gendarme Cavalry into the sixteenth century, stationed throughout France and summoned into larger armies as needed. There was also made for Francs-archers units of bowmen and foot soldiers raised from the non-noble classes. The bulk of the infantry for warfare was still provided by urban or provincial militias, raised from an area or city to fight locally and named for their recruiting grounds. Gradually these units became more permanent, and in 1480s Swiss instructors were recruited and these men would be paid and contracted and receive training. Henry II further regularised the French army by forming standing Infantry regiments to replace the Militia structure, the first of these the Régiments de Picardie, Piémont, Navarre and Champagne were called the Les Vieux Corps. It was normal policy to disband regiments after a war was over as a cost saving measure with the Vieux Corps and the Kings own Household Troops the Maison du Roi being the only survivors. Regiments could be raised directly by the King and so called after the region in which they were raised, or by the nobility and so called after the noble or his appointed colonel. In 1684 there was a reorganisation of the French infantry and again in 1701 to fit in with Louis XIVs plans. This reshuffle created many of the regiments of the French Army and standardised their equipment. The army of the Sun King tended to wear coats with coloured linings. There were exceptions and the troops, recruited from outside France. In addition to these regiments of the line the Maison du Roi provided several elite units, the Swiss Guards, French Guards, the revolution split the army with the main mass losing most of its officers to aristocratic flight or guillotine and becoming demoralised and ineffective. The French Guard joined the revolt and the Swiss Guards were massacred during the storming of the Tuileries palace, under Napoleon I, the French Army conquered most of Europe during the Napoleonic Wars

Philippe de Hauteclocque
–
Philippe François Marie Leclerc de Hauteclocque was a French general during the Second World War. He became Marshal of France posthumously in 1952, and is known in France simply as le maréchal Leclerc or just Leclerc, the son of an aristocratic family, de Hauteclocque graduated from the École spéciale militaire de Saint-Cyr, the French military academy, in 1924. After service with the French Occupation of the Ruhr and in Morocco and he was awarded the croix de guerre des théâtres dopérations extérieures for leading goumiers in an attack on caves and ravines on Bou Amdoun on 11 August 1933. During the Second World War he fought in the Battle of France and he was sent to French Equatorial Africa, where he rallied local leaders to the Free French cause, and led a force against Gabon, whose leaders supported Vichy France. From Chad he led raids into Italian-controlled Libya, after his forces captured Kufra, he had his men swear an oath known today as the Serment de Koufra, in which they pledged to fight on until their flag flew over the Strasbourg Cathedral. The forces under his command, known as L Force, campaigned in Libya in 1943, covered the Eighth Armys inland flank during its advance into Tunisia, L Force was then transformed into the 2e Division Blindée, although it was often referred to as La Division Leclerc. It fought under Leclercs command in the Battle of Normandy, and participated in the liberation of Paris, after the end of World War II in Europe in May 1945, he was given command of the French Far East Expeditionary Corps. He represented France at the surrender of the Japanese Empire in Tokyo Bay on 2 September 1945 and he quickly perceived the necessity for a political solution to the nascent conflict in Indochina, but once again was ahead of his countrymen, and was recalled to France in 1946. He was killed in an air crash in Algeria in 1947, Philippe François Marie de Hauteclocque was born on 22 November 1902 at Belloy-Saint-Léonard in the department of Somme. He was the fifth of six children of Adrien de Hauteclocque, comte de Hauteclocque, Philippe was named in honour of an ancestor killed by Croats in 1635. De Hauteclocque came from an old line of country nobility and his direct ancestors had served in the Fifth Crusade against Egypt, and again in the Eighth Crusade of Saint Louis against Tunisia in 1270. They had also fought at the Battle of Saint-Omer in 1340, the family managed to survive the French Revolution. Three members of the served in Napoleons Grande Armée and a fourth. The third son, Constantin, who had served in Napoleons Russian Campaign, was created a chevalier by King Louis XVIII, the older, Alfred Francois Marie, died childless. The younger, Gustave Francois Marie Joseph, became a noted Egyptologist, Gustave, in turn, had three sons. The first, Henry, and third, Wallerand, became officers in the French Army, serving during the colonial campaigns, both were killed in the early fighting of the First World War. The second son was Adrien, who enlisted in August 1914 as a trooper in the 11e Régiment de Chasseurs à Cheval, Adrien was later commissioned, and was twice awarded the Croix de Guerre for gallantry. He survived the war, and inherited the title and estate in Belloy-Saint-Léonard

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Relative humidity
–
Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest and it requires less water vapor to attain high relative humidity at low temperatures, more water vapour is required to attain high relative humidity in warm or hot air. Humans are sensitive to high humidity because the body uses evaporative cooling, enabled by perspiration. Perspiration evaporates from the more slowly under humid conditions than under arid. For example, if the air temperature is 24 °C and the humidity is zero percent. If the relative humidity is 100 percent at the air temperature. In other words, if the air is 24 °C and contains saturated water vapor, then the human body cools itself at the rate as it would if it were 27 °C. The heat index and the humidex are indices that reflect the effect of temperature. In cold climates, the temperature causes lower capacity for water vapour to flow about. Dry cracked skin can result from dry air, low humidity causes tissue lining nasal passages to dry, crack and become more susceptible to penetration of Rhinovirus cold viruses. Low humidity is a cause of nosebleeds. The use of a humidifier in homes, especially bedrooms, can help with these symptoms, indoor relative humidities should be kept above 30% to reduce the likelihood of the occupants nasal passages drying out. Humans can be comfortable within a range of humidities depending on the temperature—from thirty to seventy percent—but ideally between 50% and 60%. Very low humidity can create discomfort, respiratory problems, and aggravate allergies in some individuals, in the winter, it is advisable to maintain relative humidity at 30 percent or above. Extremely low relative humidities may also cause eye irritation, wooden furniture can shrink, causing the paint that covers these surfaces to fracture. When the temperature is low and the humidity is high. When relative humidity approaches 100 percent, condensation can occur on surfaces, leading to problems with mold, corrosion, decay, condensation can pose a safety risk as it can promote the growth of mold and wood rot as well as possibly freezing emergency exits shut. The basic principles for buildings, above, also apply to vehicles, in addition, there may be safety considerations

Sunshine duration
–
It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in hours per day, the first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration, an important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations, if the Sun were to be above the horizon 50% of the time for a standard year consisting of 8,760 hours, apparent maximal daytime duration would be 4,380 hours for any point on Earth. However, there are physical and astronomical effects that change that picture, namely, atmospheric refraction allows the Sun to be still visible even when it physically sets below the horizon. For that reason, average daytime is longest in polar areas, places on the Arctic Circle have the longest total annual daytime,4,647 hours, while the North Pole receives 4,575. Because of elliptic nature of the Earths orbit, the Southern Hemisphere is not symmetrical, the Equator has a total daytime of 4,422 hours per year. Given the theoretical maximum of daytime duration for a given location, bright sunshine hours represent the total hours when the sunlight is stronger than a specified threshold, as opposed to just visible hours. Visible sunshine, for example, occurs around sunrise and sunset, measurement is performed by instruments called sunshine recorders. For the specific purpose of sunshine duration recording, Campbell–Stokes recorders are used, when the intensity exceeds a pre-determined threshold, the tape burns. The total length of the trace is proportional to the number of bright hours. Another type of recorder is the Jordan sunshine recorder, newer, electronic recorders have more stable sensitivity than that of the paper tape. In 2003, the duration was finally defined as the period during which direct solar irradiance exceeds a threshold value of 120 W/m². The sky is clear in these regions, and fair weather is virtually perpetual, the descending branch of the Hadley cell and the long-term lack of atmospheric disturbances helps to explain the seemingly endless supply of sunny, cloud-free days in the deserts. Low clouding conditions are associated with rainfall shortage, as seen in these dry regions. In the belt encompassing northern Chad and the Tibesti Mountains, northern Sudan, southern Libya, some places in the interior of the Arabian Peninsula receive 3, 600–3,800 hours of bright sunshine annually. The largest sun-baked region in the world is North Africa, the sunniest month in the world is December in Eastern Antarctica, with almost 23 hours of bright sun daily

Blazon
–
In heraldry and heraldic vexillology, a blazon is a formal description of a coat of arms, flag or similar emblem, from which the reader can reconstruct the appropriate image. The verb to blazon means to such a description. Blazon also refers to the language in which a blazon is written. This language has its own vocabulary, grammar and syntax, or rules governing word order, other objects — such as badges, banners, and seals — may also be described in blazon. The word blazon is not to be confused with the verb to emblazon, or the noun emblazonment, the word blazon is derived from French blason, shield. It was found in English by the end of the 14th century, formerly, experts in heraldry assumed that the word was related to the German verb blasen, to blow. Present-day lexicographers reject this theory as conjectural and disproved, the blazon of armorials follows a rigid formula, designed to eliminate ambiguity of interpretation, to be as concise as possible and to avoid repetition and extraneous punctuation. The nomenclature is equally significant, and its aim is to combine definitive exactness with a brevity that is indeed laconic. The rules of blazonry are as follows, Every blazon of a coat of arms begins by describing the field, with first letter as a capital, in a majority of cases this is a single tincture, e. g. Azure. If the field is complex, the variation is described, followed by the used, e. g. Chequy gules. The most common names are historically abbreviated. A Tincture is named only once in a given blazon, the principal charge are then named, with their tincture, e. g. a bend or. The principal charge is followed by any other charges placed around or on it, if a charge be a bird or beast, its attitude is described, followed by the animals tincture, followed by anything that may be differently coloured, e. g. An eagle displayed gules armed and wings charged with trefoils or, any accessories present — such as crown/coronet, helmet, torse, mantling, crest, motto, supporters and compartment — are then described in turn, using the same terminology and syntax. According to Boutell, It appears desirable always to print all heraldic blazon in italic, heraldry has its own vocabulary, word-order and punctuation, and showing it in italics thus indicates to the reader the presence of a quasi-foreign language. A quartered shield is blazoned one quarter at a time, proceeding by rows from chief to base, a divided shield is blazoned party per or parted per, though the word party or parted is almost always omitted. A tincture is sometimes replaced by of the first, of the second etc. to avoid repetition of tincture names, counterchanged means that a charge which straddles a line of division is tinctured of the same tinctures as the divided field, reversed. But as to the formulae of blazoning, John Brooke-Little, Norroy and Ulster King of Arms, wrote in 1985
