Holy Roman Empire
–
The Holy Roman Empire was a multi-ethnic complex of territories in central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806. On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne as Emperor, reviving the title in Western Europe, more than three centuries after the fall of the Western Roman Empire. The title was revived in 962 when Otto I was crowned emperor, fashioning himself as the successor of Charlemagne, some historians refer to the coronation of Charlemagne as the origin of the empire, while others prefer the coronation of Otto I as its beginning. Scholars generally concur, however, in relating an evolution of the institutions and principles constituting the empire, the office of Holy Roman Emperor was traditionally elective, although frequently controlled by dynasties. Emperor Francis II dissolved the empire on 6 August 1806, after the creation of the Confederation of the Rhine by Napoleon, before 1157, the realm was merely referred to as the Roman Empire. In a decree following the 1512 Diet of Cologne, the name was changed to Holy Roman Empire of the German Nation, by the end of the 18th century, the term Holy Roman Empire of the German Nation had fallen out of official use. As Roman power in Gaul declined during the 5th century, local Germanic tribes assumed control, by the middle of the 8th century, however, the Merovingians had been reduced to figureheads, and the Carolingians, led by Charles Martel, had become the de facto rulers. In 751, Martel’s son Pepin became King of the Franks, the Carolingians would maintain a close alliance with the Papacy. In 768 Pepin’s son Charlemagne became King of the Franks and began an expansion of the realm. He eventually incorporated the territories of present-day France, Germany, northern Italy, on Christmas Day of 800, Pope Leo III crowned Charlemagne emperor, restoring the title in the west for the first time in over three centuries. After the death of Charles the Fat in 888, however, the Carolingian Empire broke apart, according to Regino of Prüm, the parts of the realm spewed forth kinglets, and each part elected a kinglet from its own bowels. After the death of Charles the Fat, those crowned emperor by the pope controlled only territories in Italy, the last such emperor was Berengar I of Italy, who died in 924. Around 900, autonomous stem duchies reemerged in East Francia, on his deathbed, Conrad yielded the crown to his main rival, Henry the Fowler of Saxony, who was elected king at the Diet of Fritzlar in 919. Henry reached a truce with the raiding Magyars, and in 933 he won a first victory against them in the Battle of Riade, Henry died in 936, but his descendants, the Liudolfing dynasty, would continue to rule the Eastern kingdom for roughly a century. Upon Henry the Fowlers death, Otto, his son and designated successor, was elected King in Aachen in 936 and he overcame a series of revolts from an elder brother and from several dukes. After that, the managed to control the appointment of dukes. In 951, Otto came to the aid of Adelaide, the queen of Italy, defeating her enemies, marrying her. In 955, Otto won a victory over the Magyars in the Battle of Lechfeld

Spanish Empire
–
The Spanish Empire was one of the largest empires in history. The Spanish Empire became the foremost global power of its time and was the first to be called the empire on which the sun never sets, the Spanish Empire originated during the Age of Discovery after the voyages of Christopher Columbus. Following the Spanish–American War of 1898, Spain ceded its last colonies in the Caribbean and its last African colonies were granted independence or abandoned during Decolonisation of Africa finishing in 1976. The unity did not mean uniformity, nevertheless, some historians assert that Portugal was part of the Spanish monarchy at the time, while others draw a clear distinction between the Portuguese and Spanish empires. During the 15th century, Castile and Portugal became territorial and commercial rivals in the western Atlantic. The conquest was completed with the campaigns of the armies of the Crown of Castile between 1478 and 1496, when the islands of Gran Canaria, La Palma, and Tenerife were subjugated. The Portuguese tried in vain to keep secret their discovery of the Gold Coast in the Gulf of Guinea, chronicler Pulgar wrote that the fame of the treasures of Guinea spread around the ports of Andalusia in such way that everybody tried to go there. Worthless trinkets, Moorish textiles, and above all, shells from the Canary and Cape Verde islands were exchanged for gold, slaves, ivory and Guinea pepper. The Crown officially organized this trade with Guinea, every caravel had to get a government license, the treaty delimited the spheres of influence of the two countries, establishing the principle of the Mare clausum. It was confirmed in 1481 by the Pope Sixtus IV, in the papal bull Æterni regis, thus, the limitations imposed by the Alcáçovas treaty were overcome and a new and more balanced worlds division would be reached at Tordesillas between both emerging maritime powers. Seven months before the treaty of Alcaçovas, King John II of Aragon died, Ferdinand and Isabella drove the last Moorish king out of Granada in 1492 after a ten-year war. The Catholic Monarchs then negotiated with Christopher Columbus, a Genoese sailor attempting to reach Cipangu by sailing west, Castile was already engaged in a race of exploration with Portugal to reach the Far East by sea when Columbus made his bold proposal to Isabella. Columbus discoveries inaugurated the Spanish colonization of the Americas and these actions gave Spain exclusive rights to establish colonies in all of the New World from north to south, as well as the easternmost parts of Asia. The treaty of Tordesillas was confirmed by Pope Julius II in the bull Ea quae pro bono pacis on 24 January 1506, Spains expansion and colonization was driven by economic influences, a yearning to improve national prestige, and a desire to spread Catholicism into the New World. The Catholic Monarchs had developed a strategy of marriages for their children in order to isolate their long-time enemy, the Spanish princes married the heirs of Portugal, England and the House of Habsburg. Following the same strategy, the Catholic Monarchs decided to support the Catalan-Aragonese house of Naples against Charles VIII of France in the Italian Wars beginning in 1494. As King of Aragon, Ferdinand had been involved in the struggle against France and Venice for control of Italy, these conflicts became the center of Ferdinands foreign policy as king. Only a year later, Ferdinand became part of the Holy League against France and this war was less of a success than the war against Venice, and in 1516, France agreed to a truce that left Milan in its control and recognized Spanish control of Upper Navarre

Habsburg Monarchy
–
The Monarchy was a composite state composed of territories within and outside the Holy Roman Empire, united only in the person of the monarch. The dynastic capital was Vienna, except from 1583 to 1611, from 1804 to 1867 the Habsburg Monarchy was formally unified as the Austrian Empire, and from 1867 to 1918 as the Austro-Hungarian Empire. The two entities were never coterminous, as the Habsburg Monarchy covered many lands beyond the Holy Roman Empire, the monarchy had no official name. The entity had no official name, Austrian Empire, This was the official name. Note that the German version is Kaisertum Österreich, i. e. the English translation empire refers to a territory ruled by an emperor, Austria-Hungary, This was the official name. An unofficial popular name was the Danubian Monarchy also often used was the term Doppel-Monarchie meaning two states under one crowned ruler, Crownlands or crown lands, This is the name of all the individual parts of the Austrian Empire, and then of Austria-Hungary from 1867 on. The Hungarian parts of the Empire were called Lands of the Holy Hungarian Crown of Saint Stephen or Lands of Holy Stephens Crown, the Bohemian Lands were called Lands of the St. Wenceslaus Crown. Burgenland came to Austria in 1921 from Hungary, Salzburg finally became Austrian in 1816 after the Napoleonic wars. Vienna, Austrias capital became a state January 1,1922, after being residence, Upper and Lower Austria, historically, were split into Austria above the Enns and Austria below the Enns. Upper Austria was enlarged after the Treaty of Teschen following the War of the Bavarian Succession by the so-called Innviertel, formerly part of Bavaria. Hereditary Lands or German Hereditary Lands or Austrian Hereditary Lands, In a narrower sense these were the original Habsburg Austrian territories, i. e. basically the Austrian lands, in a wider sense the Lands of the Bohemian Crown were also included in the Hereditary lands. The term was replaced by the term Crownlands in the 1849 March Constitution, within the Habsburg Monarchy, each province was governed according to its own particular customs. Until the mid 17th century, not all of the provinces were even necessarily ruled by the same members of the family often ruled portions of the Hereditary Lands as private apanages. An even greater attempt at centralization began in 1849 following the suppression of the revolutions of 1848. For the first time, ministers tried to transform the monarchy into a bureaucratic state ruled from Vienna. The Kingdom of Hungary, in particular, ceased to exist as a separate entity, in this system, the Kingdom of Hungary was given sovereignty and a parliament, with only a personal union and a joint foreign and military policy connecting it to the other Habsburg lands. When Bosnia and Herzegovina was annexed, it was not incorporated into either half of the monarchy, instead, it was governed by the joint Ministry of Finance. Austria-Hungary collapsed under the weight of the various unsolved ethnic problems that came to a head with its defeat in World War I, to these were added in 1779 the Inn Quarter of Bavaria, and in 1803 the Bishoprics of Trent and Brixen

Gian Galeazzo Visconti
–
Gian Galeazzo Visconti, son of Galeazzo II Visconti and Bianca of Savoy, was the first Duke of Milan and ruled the late-medieval city just before the dawn of the Renaissance. He was the founding patron of the Certosa di Pavia, completing the Visconti Castle at Pavia begun by his father. During his patronage of the Visconti Castle, he contributed greatly to the growth of the collection of scientific treatises, although most famous as Signore of Milan, Gian Galeazzo was the son of Galeazzo II Visconti who possessed the signoria of the city of Pavia. In 1385 Gian Galeazzo gained control of Milan by overthrowing his uncle Bernabò through treacherous means and he imprisoned his uncle who soon died, supposedly poisoned on his orders. His first marriage was to Isabelle of Valois, who brought him the title of comte de Vertus in Champagne, rendered in Italian as Conte di Virtù, the title by which he was known in his early career. A devoted father to his daughter Valentina, Gian Galeazzo reacted to gossip about Valentina at the French Court by threatening to declare war on France. The wife of King Charles VI of France was Isabeau of Bavaria, the granddaughter of Bernabò Visconti, and, thus, galeazzos role as a statesman also took other forms. He lost Padua in 1390, when it reverted to Francesco Novello da Carrara and he received the title of Duke of Milan from Wenceslaus, King of the Romans in 1395 for 100,000 florins. In 1400, Gian Galeazzo appointed a host of clerks and departments entrusted with improving the public health, for the new system of administration and bookkeeping this established, he is credited with creating the first modern bureaucracy. Gian Galeazzo had dreams of uniting all of northern Italy into one kingdom, the obstacles to his success included Bologna and especially Florence. In 1402, Gian Galeazzo launched assaults upon these cities, the warfare was extremely costly on both sides, but it was universally believed the Milanese would emerge victorious. The Florentine leaders, especially the chancellor Coluccio Salutati worked successfully to rally the people of Florence, but the Florentines were being taxed hard by famine, disease, Galeazzo won another victory over the Bolognese at the Battle of Casalecchio on 26 June 1402. Galeazzos dreams were to come to naught, however, as he succumbed to a fever at the castello of Melegnano on 10 August 1402 and his empire fragmented as infighting among his successors wrecked Milan, partly through his division of his lands among both legitimate and illegitimate heirs.

Early modern period
–
The early modern period of modern history follows the late Middle Ages of the post-classical era. Historians in recent decades have argued that from a worldwide standpoint, the period witnessed the exploration and colonization of the Americas and the rise of sustained contacts between previously isolated parts of the globe. The historical powers became involved in trade, as the exchange of goods, plants, animals, and food crops extended to the Old World. The Columbian Exchange greatly affected the human environment, New economies and institutions emerged, becoming more sophisticated and globally articulated over the course of the early modern period. This process began in the medieval North Italian city-states, particularly Genoa, Venice, the early modern period also included the rise of the dominance of the economic theory of mercantilism. The European colonization of the Americas, Asia, and Africa occurred during the 15th to 19th centuries, the early modern trends in various regions of the world represented a shift away from medieval modes of organization, politically and economically. Historians typically date the end of the modern period when the French Revolution of the 1790s began the modern period. Early modern themes Other In 16th century China, the Ming Dynastys economy was stimulated by trade with the Portuguese, Spanish. China became involved in a new trade of goods, plants, animals. Trade with Early Modern Europe and Japan brought in massive amounts of silver, during the last decades of the Ming the flow of silver into China was greatly diminished, thereby undermining state revenues and the entire Chinese economy. This damage to the economy was compounded by the effects on agriculture of the incipient Little Ice Age, natural calamities, crop failure, the ensuing breakdown of authority and peoples livelihoods allowed rebel leaders such as Li Zicheng to challenge Ming authority. The Ming Dynasty fell around 1644 to the Qing Dynasty, which was the last ruling dynasty of China, during its reign, the Qing Dynasty became highly integrated with Chinese culture. The Azuchi-Momoyama period saw the unification that preceded the establishment of the Tokugawa shogunate. The Edo period from 1600 to 1868 characterized early modern Japan, the Tokugawa shogunate was a feudal regime of Japan established by Tokugawa Ieyasu and ruled by the shoguns of the Tokugawa family. This period gets its name from the city, Edo. The Tokugawa shogunate ruled from Edo Castle from 1603 until 1868, in 1392, General Yi Seong-gye established the Joseon Dynasty with a largely bloodless coup. Joseon experienced advances in science and culture, King Sejong the Great promulgated hangul, the Korean alphabet. The period saw various other cultural and technological advances as well as the dominance of neo-Confucianism over the entirety of Korea, during the late 16th and early 17th centuries, invasions by the neighboring Japanese and Qing Chinese nearly overran the Korean peninsula

Golden Ambrosian Republic
–
The Golden Ambrosian Republic was a short-lived government founded in Milan by members of the University of Pavia with popular support. With the aid of Francesco Sforza they held out against the forces of the Republic of Venice, Filippo Maria had no heir through male bloodlines, but the day before his death had written a will dedicating the Duchy to Alfonso V of Aragon. The Bracceschi, supporters of the King of Aragon, seized the Castello on the night of the 13th, almost before Filippo Maria died, despite the general support for either Alfonso or Sforza, other influential citizens believed that the old republic could be restored. Learned bodies, such as the College of Jurisprudence in Pavia, the merchants, seeing the prosperity of Republican Venice, were behind this idea. A Republic was declared behind the Palace of the Commune, the Bracceschi were driven from Milan, and the new republic was called the Golden Ambrosian Republic, named for St. Ambrose, the 4th century bishop of Milan, who was taken on as the Republics patron. Venice was already at war with Milan, and the Republic was struck a blow as previously Milanese cities including Pavia, Lodi. Besides the loss of support and defensive locations, the drop in revenue also caused a financial crisis resolved by the imposition of new taxes. Venice, now occupying Lodi and Piacenza, refused to listen to Milans pleas for peace, Milan turned to Francesco Sforza, the greatest military leader of his day, offering him the position of Captain-General and the city of Brescia. Although he wished - and indeed, planned - to succeed his father-in-law as Duke, he decided to accept the position, a draft was declared in Milan on 13 September. Sforza promised the Pavians no new taxes, respect for the old laws, payment for his hired officials and he kept these promises faithfully and so won over the people of Pavia, establishing his rulership. Pavia was previously almost a second capital to Milan, and gave Sforza his own seat of power, the city was also in a strategic location on the Po River, situated where it could block the Venetians from coming to the relief of the beleaguered Piacenza via water. Returning to the siege of Piacenza and finding the city not likely to crumble by starvation, employing cannons in an almost unheard-of manner, he opened up a breach in Piacenzas walls and sacked the city. The news of Piacenzas sack was greeted by three days rejoicing in Milan, meanwhile, Milanese Captain Bartolomeo Colleoni captured Tortona which had previously proclaimed Sforza as its lord, stealing it from the now dangerously powerful Sforza. This caused further and even greater rejoicing, for the Milanese feared Sforza, in January 1448, the terms of the previous Captains and Defenders ended, and in the following election the Guelphs rose to political prominence. Being especially adverse to Sforza, they entered negotiations with Venice. Two of the Ghibellines who helped to found the Republic, namely Lampugnano and Bossi, the Council of Nine Hundred was forced to abandon its plans for peace, and Sforza was given the go-ahead for his next campaign to seize the Adda River. Sforzas plans were voted down by the Republic in favor of more traditional tactics, while this happened, the Venetian fleet under Andrea Quirini assaulted the bridge of Cremona. However, Sforzas wife Bianca was there, and led the defense until her husband relieved the city, the Venetian fleet withdrew and entrenched while it waited for the arrival of the Venetian army

Habsburg Spain
–
Habsburg Spain refers to the history of Spain over the 16th and 17th centuries, when it was ruled by kings from the House of Habsburg. The Habsburg rulers reached the zenith of their influence and power and this period of Spanish history has also been referred to as the Age of Expansion. The Habsburg years were also a Spanish Golden Age of cultural efflorescence, in some cases, these individual kingdoms themselves were confederations, most notably, the Crown of Aragon. Isabella and Ferdinand were bestowed the title of Most Catholic Monarchs by Pope Alexander VI in 1496, the Habsburg period is formative of the notion of Spain in the sense that was institutionalized in the 18th century. Her husband Philip I was the Habsburg son of the Holy Roman Emperor Maximilian I, shortly thereafter Joanna began to lapse into insanity, though how mentally ill she actually was the topic of some debate. In 1506, Philip I was declared jure uxoris king, but he died later that year under mysterious circumstances, possibly poisoned by his father-in-law, Ferdinand II. Since their oldest son Charles was only six, the Cortes reluctantly allowed Joannas father Ferdinand II to rule the country as the regent of Joanna, Spain was now in personal union under Ferdinand II of Aragon. He also attempted to enlarge Spains sphere of influence in Italy, as ruler of Aragon, Ferdinand had been involved in the struggle against France and the Republic of Venice for control of Italy, these conflicts became the center of Ferdinands foreign policy as king. The war was less of a success than that against Venice, Ferdinand would die later that year. Ferdinands death led to the ascension of young Charles to the throne as Charles I of Castile and Aragon and his Spanish inheritance included all the Spanish possessions in the New World and around the Mediterranean. Upon the death of his Habsburg father in 1506, Charles had inherited the Netherlands and Franche-Comté, in 1519, with the death of his paternal grandfather Maximilian I, Charles inherited the Habsburg territories in Germany, and was duly elected as Holy Roman Emperor that year. At that point, Emperor and King Charles was the most powerful man in Christendom, the accumulation of so much power by one man and one dynasty greatly concerned Francis I of France, who found himself surrounded by Habsburg territories. In 1521 Francis invaded the Spanish possessions in Italy and Navarre, the war was a disaster for France, which suffered defeats at Biccoca, Pavia, and Landriano before Francis relented and abandoned Milan to Spain once more. Charless victory at the Battle of Pavia surprised many Italians and Germans, Pope Clement VII switched sides and now joined forces with France and prominent Italian states against the Habsburg Emperor, in the War of the League of Cognac. Henry VIII of England, who bore a grudge against France than he held against the Emperor for standing in the way of his divorce. Although the Spanish army was defeated at the Battle of Ceresole, in Savoy Henry fared better. The Austrians, led by Charless younger brother Ferdinand, continued to fight the Ottomans in the east, with France defeated, Charles went to take care of an older problem, the Schmalkaldic League. The Protestant Reformation had begun in Germany in 1517, the German Peasants War broke out in Germany in 1524 and ravaged the country until it was brutally put down in 1526, Charles, even as far away from Germany as he was, was committed to keeping order

Italy
–
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world

Switzerland
–
Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The country is situated in western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km2. The establishment of the Old Swiss Confederacy dates to the medieval period, resulting from a series of military successes against Austria. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The country has a history of armed neutrality going back to the Reformation, it has not been in a state of war internationally since 1815, nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to international organisations. On the European level, it is a member of the European Free Trade Association. However, it participates in the Schengen Area and the European Single Market through bilateral treaties, spanning the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions, German, French, Italian and Romansh. Due to its diversity, Switzerland is known by a variety of native names, Schweiz, Suisse, Svizzera. On coins and stamps, Latin is used instead of the four living languages, Switzerland is one of the most developed countries in the world, with the highest nominal wealth per adult and the eighth-highest per capita gross domestic product according to the IMF. Zürich and Geneva have each been ranked among the top cities in the world in terms of quality of life, with the former ranked second globally, according to Mercer. The English name Switzerland is a compound containing Switzer, a term for the Swiss. The English adjective Swiss is a loan from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, the Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for Confederates, Eidgenossen, used since the 14th century. The data code for Switzerland, CH, is derived from Latin Confoederatio Helvetica. The toponym Schwyz itself was first attested in 972, as Old High German Suittes, ultimately related to swedan ‘to burn’

Po Valley
–
The Po Valley, Po Plain, Plain of the Po, or Padan Plain is a major geographical feature of Italy. The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, the plain is the surface of an in-filled system of ancient canyons extending from the Apennines in the south to the Alps in the north, including the northern Adriatic. Geo-political definitions of the valley depend on the defining authority, the Po Basin Water Board, authorized in 1989 by Law no. The law defines the Po basin as the territory from which rainwater or snow and glacier melt flows on the surface, the valley is crossed by a number of affluents running down from the Alps in the north and from the Apennines in the south. The Pos major affluents include the Tanaro, Scrivia, Trebbia, Panaro and Secchia in the south, Dora Riparia, Dora Baltea, Sesia, Ticino, Lambro, Adda, Oglio and Mincio in the north. Since the Messinian the system has been filling with sediment mainly from the older Apennines, the shoreline of the Adriatic depends on a balance between the sedimentation rate and isostatic factors. Until about 1950 the Po delta was prograding into the Adriatic, where the land surface now dips below sea level the river must run at a relative elevation between dikes. The Po Valley is often regarded as a syncline, or dip in the crust due to compression at the edges. Regardless of whether this concept accurately describes its geology, the valley is manifestly a sediment-filled trough, or virtual syncline, the upper areas of the Po valley take local names which reflect in their meanings their being modestly suited for farming. It varies from a few kilometres to as much as 50 km wide, the fontanili line is the outcrop, or intersection, of the anticlines water table with the surface at the edge of the bassa. The rock above the line is porous, surface water in the intermittent streams of the mountains tends to disappear below ground only to spring out again in the spring zone. The spring zone is called the middle valley. Surface runoff water is not of value to the valleys dense population for drinking and other immediate uses, being unreliable, often destructive and heavily polluted by sewage. Its main anthropic value is for power, irrigation and industrial transport. The cost of purifying it for consumption makes that process less feasible. The fresh drinking water comes from hundreds of thousands of wells concentrated especially in the fontanili zone, the older and smaller cities deriving from ancient times are still located there. The Po Valley has a subtropical climate. The conformation of the plain, surrounded by the Alps and the Apennines, the climate of the Po Valley becomes increasingly warmer and more humid farther south and east
