American Revolution
–
The British responded by imposing punitive laws on Massachusetts in 1774 known as the Coercive Acts, following which Patriots in the other colonies rallied behind Massachusetts. Tensions escalated to the outbreak of fighting between Patriot militia and British regulars at Lexington and Concord in April 1775, the conflict then developed into a global war, during which the Patriots fought the British and Loyalists in what became known as the American Revolutionary War. The Continental Congress determined King George IIIs rule to be tyrannical and infringing the rights as Englishmen. The Patriot leadership professed the political philosophies of liberalism and republicanism to reject monarchy and aristocracy, Congress rejected British proposals requiring allegiance to the monarchy and abandonment of independence. The British were forced out of Boston in 1776, but then captured and they blockaded the ports and captured other cities for brief periods, but failed to defeat Washingtons forces. After a failed Patriot invasion of Canada, a British army was captured at the Battle of Saratoga in late 1777, a combined American–French force captured a second British army at Yorktown in 1781, effectively ending the war in the United States. The Treaty of Paris in 1783 formally ended the conflict, confirming the new nations complete separation from the British Empire. The United States took possession of all the territory east of the Mississippi River and south of the Great Lakes, with the British retaining control of Canada. Among the significant results of the revolution was the creation of a new Constitution of the United States. Historians typically begin their histories of the American Revolution with the British victory in the French and Indian War in 1763, the lands west of Quebec and west of a line running along the crest of the Allegheny mountains became Indian territory, temporarily barred to settlement. For the prior history, see Thirteen Colonies, in 1764, Parliament passed the Currency Act to restrain the use of paper money which British merchants saw as a means to evade debt payments. Parliament also passed the Sugar Act, imposing customs duties on a number of articles, none did and Parliament passed the Stamp Act in March 1765 which imposed direct taxes on the colonies for the first time. All official documents, newspapers, almanacs, and pamphlets—even decks of playing cards—were required to have the stamps, the colonists did not object that the taxes were high, but because they had no representation in the Parliament. Benjamin Franklin testified in Parliament in 1766 that Americans already contributed heavily to the defense of the Empire, stationing a standing army in Great Britain during peacetime was politically unacceptable. London had to deal with 1,500 politically well-connected British officers who became redundant, in 1765, the Sons of Liberty formed. They used public demonstrations, boycott, violence, and threats of violence to ensure that the British tax laws were unenforceable, in Boston, the Sons of Liberty burned the records of the vice admiralty court and looted the home of chief justice Thomas Hutchinson. Several legislatures called for united action, and nine colonies sent delegates to the Stamp Act Congress in New York City in October 1765, moderates led by John Dickinson drew up a Declaration of Rights and Grievances stating that taxes passed without representation violated their rights as Englishmen. Colonists emphasized their determination by boycotting imports of British merchandise, the Parliament at Westminster saw itself as the supreme lawmaking authority throughout all British possessions and thus entitled to levy any tax without colonial approval

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

Napoleon
–
Napoleon Bonaparte was a French military and political leader who rose to prominence during the French Revolution and led several successful campaigns during the French Revolutionary Wars. As Napoleon I, he was Emperor of the French from 1804 until 1814, Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions in the Napoleonic Wars. He won most of these wars and the vast majority of his battles, one of the greatest commanders in history, his wars and campaigns are studied at military schools worldwide. Napoleons political and cultural legacy has ensured his status as one of the most celebrated and he was born Napoleone di Buonaparte in Corsica to a relatively modest family from the minor nobility. When the Revolution broke out in 1789, Napoleon was serving as an officer in the French army. Seizing the new opportunities presented by the Revolution, he rose through the ranks of the military. The Directory eventually gave him command of the Army of Italy after he suppressed a revolt against the government from royalist insurgents, in 1798, he led a military expedition to Egypt that served as a springboard to political power. He engineered a coup in November 1799 and became First Consul of the Republic and his ambition and public approval inspired him to go further, and in 1804 he became the first Emperor of the French. Intractable differences with the British meant that the French were facing a Third Coalition by 1805, in 1806, the Fourth Coalition took up arms against him because Prussia became worried about growing French influence on the continent. Napoleon quickly defeated Prussia at the battles of Jena and Auerstedt, then marched the Grand Army deep into Eastern Europe, France then forced the defeated nations of the Fourth Coalition to sign the Treaties of Tilsit in July 1807, bringing an uneasy peace to the continent. Tilsit signified the high watermark of the French Empire, hoping to extend the Continental System and choke off British trade with the European mainland, Napoleon invaded Iberia and declared his brother Joseph the King of Spain in 1808. The Spanish and the Portuguese revolted with British support, the Peninsular War lasted six years, featured extensive guerrilla warfare, and ended in victory for the Allies. The Continental System caused recurring diplomatic conflicts between France and its client states, especially Russia, unwilling to bear the economic consequences of reduced trade, the Russians routinely violated the Continental System and enticed Napoleon into another war. The French launched an invasion of Russia in the summer of 1812. The resulting campaign witnessed the collapse of the Grand Army, the destruction of Russian cities, in 1813, Prussia and Austria joined Russian forces in a Sixth Coalition against France. A lengthy military campaign culminated in a large Allied army defeating Napoleon at the Battle of Leipzig in October 1813, the Allies then invaded France and captured Paris in the spring of 1814, forcing Napoleon to abdicate in April. He was exiled to the island of Elba near Rome and the Bourbons were restored to power, however, Napoleon escaped from Elba in February 1815 and took control of France once again. The Allies responded by forming a Seventh Coalition, which defeated Napoleon at the Battle of Waterloo in June, the British exiled him to the remote island of Saint Helena in the South Atlantic, where he died six years later at the age of 51

Telephone
–
A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. In 1876, Scottish emigrant Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice and this instrument was further developed by many others. The telephone was the first device in history that people to talk directly with each other across large distances. Telephones rapidly became indispensable to businesses, government, and households, the essential elements of a telephone are a microphone to speak into and an earphone which reproduces the voice in a distant location. Until approximately the 1970s most telephones used a dial, which was superseded by the modern DTMF push-button dial. The receiver and transmitter are usually built into a handset which is held up to the ear, the dial may be located either on the handset, or on a base unit to which the handset is connected. The transmitter converts the sound waves to electrical signals which are sent through the network to the receiving phone. The receiving telephone converts the signals into audible sound in the receiver, telephones permit duplex communication, meaning they allow the people on both ends to talk simultaneously. The first telephones were connected to each other from one customers office or residence to another customers location. Being impractical beyond just a few customers, these systems were replaced by manually operated centrally located switchboards. For greater mobility, various systems were developed for transmission between mobile stations on ships and automobiles in the middle 20th century. Hand-held mobile phone]s was introduced for personal service starting in 1973, by the late 1970s several mobile telephone networks operated around the world. In 1983, the Advanced Mobile Phone System was launched, offering a standardized technology providing portability for users far beyond the residence or office. These analog cellular system evolved into digital networks with better security, greater capacity, better regional coverage, the public switched telephone network, with its hierarchical system of many switching centers, interconnects telephones around the world for communication with each other. With the standardized international numbering system, E.164, each line has an identifying telephone number. Although originally designed for voice communications, convergence has enabled most modern cell phones to have many additional capabilities. Since 1999, the trend for mobile phones is smartphones that integrate all mobile communication, a traditional landline telephone system, also known as plain old telephone service, commonly carries both control and audio signals on the same twisted pair of insulated wires, the telephone line. The control and signaling equipment consists of three components, the ringer, the hookswitch, and a dial, the ringer, or beeper, light or other device, alerts the user to incoming calls

Moon landing
–
A Moon landing is the arrival of a spacecraft on the surface of the Moon. This includes both manned and unmanned missions, the first human-made object to reach the surface of the Moon was the Soviet Unions Luna 2 mission, on 13 September 1959. The United States Apollo 11 was the first manned mission to land on the Moon, on 20 July 1969, there have been six manned U. S. landings and numerous unmanned landings, with no soft landings happening from 22 August 1976 until 14 December 2013. To date, the United States is the country to have successfully conducted manned missions to the Moon. Since then, twelve Soviet and U. S. spacecraft have used braking rockets to make landings and perform scientific operations on the lunar surface. In 1966 the USSR accomplished the first soft landings and took the first pictures from the surface during the Luna 9. The U. S. followed with five unmanned Surveyor soft landings, the Soviet Union achieved the first unmanned lunar soil sample return with the Luna 16 probe on 24 September 1970. This was followed by Luna 20 and Luna 24 in 1972 and 1976, following the failure at launch in 1969 of the first Lunokhod, Luna E-8 No.201, the Luna 17 and Luna 21 were successful unmanned lunar rover missions in 1970 and 1973. Many missions were failures at launch, in addition, several unmanned landing missions achieved the Lunar surface but were unsuccessful, including, Luna 15, Luna 18, and Luna 23 all crashed on landing, and the U. S. Surveyor 4 lost all radio contact only moments before its landing, more recently, other nations have crashed spacecraft on the surface of the Moon at speeds of around 8,000 kilometres per hour, often at precise, planned locations. These have generally been end-of-life lunar orbiters that, because of system degradations, japans lunar orbiter Hiten impacted the Moons surface on 10 April 1993. The European Space Agency performed a controlled impact with their orbiter SMART-1 on 3 September 2006. Indian Space Research Organisation performed a controlled impact with its Moon Impact Probe on 14 November 2008. The MIP was a probe from the Indian Chandrayaan-1 lunar orbiter. The Chinese lunar orbiter Change 1 executed a crash onto the surface of the Moon on 1 March 2009. The rover mission Change 3 was launched on 1 December 2013, a total of twelve men have landed on the Moon. Cernan was the last to step off the lunar surface, all Apollo lunar missions had a third crew member who remained on board the Command Module. The last three missions had a rover for increased mobility, in order to go to the Moon, a spacecraft must first leave the gravity well of the Earth

Nuclear weapon
–
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from small amounts of matter. The first test of a bomb released the same amount of energy as approximately 20,000 tons of TNT. The first thermonuclear bomb test released the same amount of energy as approximately 10 million tons of TNT, a thermonuclear weapon weighing little more than 2,400 pounds can produce an explosive force comparable to the detonation of more than 1.2 million tons of TNT. A nuclear device no larger than traditional bombs can devastate a city by blast, fire. Nuclear weapons are considered weapons of destruction, and their use. Nuclear weapons have been used twice in nuclear warfare, both times by the United States against Japan near the end of World War II, the bombings resulted in the deaths of approximately 200,000 civilians and military personnel from acute injuries sustained from the explosions. The ethics of the bombings and their role in Japans surrender remain the subject of scholarly, since the atomic bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated on over two thousand occasions for the purposes of testing and demonstration. Only a few nations possess such weapons or are suspected of seeking them, israel is also believed to possess nuclear weapons, though in a policy of deliberate ambiguity, it does not acknowledge having them. Germany, Italy, Turkey, Belgium and the Netherlands are nuclear weapons sharing states, south Africa is the only country to have independently developed and then renounced and dismantled its nuclear weapons. Modernisation of weapons continues to occur, all existing nuclear weapons derive some of their explosive energy from nuclear fission reactions. Weapons whose explosive output is exclusively from fission reactions are commonly referred to as bombs or atom bombs. This has long noted as something of a misnomer, as their energy comes from the nucleus of the atom. The latter approach is considered more sophisticated than the former and only the approach can be used if the fissile material is plutonium. A major challenge in all nuclear weapon designs is to ensure that a significant fraction of the fuel is consumed before the weapon destroys itself. The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons of TNT, all fission reactions necessarily generate fission products, the radioactive remains of the atomic nuclei split by the fission reactions. Many fission products are highly radioactive or moderately radioactive. Fission products are the radioactive component of nuclear fallout

Electric light
–
An electric light is a device that produces visible light by the flow of electric current. It is the most common form of lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening. In technical usage, a component that produces light from electricity is called a lamp. Compact lamps are commonly called light bulbs, for example, the incandescent light bulb, lamps usually have a base made of ceramic, metal, glass or plastic, which secures the lamp in the socket of a light fixture. The electrical connection to the socket may be made with a screw-thread base, before electric lighting became common in the early 20th century, people used candles, gas lights, oil lamps, and fires. Humphry Davy developed the first incandescent light in 1802, followed by the first practical electric arc light in 1806, by the 1870s, Davys arc lamp had been successfully commercialized, and was used to light many public spaces. The energy efficiency of electric lighting has increased radically since the first demonstration of arc lamps, modern electric light sources come in a profusion of types and sizes adapted to myriad applications. Most modern electric lighting is powered by centrally generated electric power, battery-powered light is often reserved for when and where stationary lights fail, often in the form of flashlights, electric lanterns, and in vehicles. *Color temperature is defined as the temperature of a body emitting a similar spectrum. The most efficient source of light is the low-pressure sodium lamp. It produces, for all purposes, a monochromatic orange/yellow light. For this reason, it is reserved for outdoor public lighting usages. Low-pressure sodium lights are favoured for public lighting by astronomers, since the pollution that they generate can be easily filtered. The modern incandescent light bulb, with a filament of tungsten, was commercialized in the 1920s developed from the carbon filament lamp introduced in about 1880. Sri Lanka has already banned importing filament bulbs because of use of electricity. Less than 3% of the energy is converted into usable light. Nearly all of the energy ends up as heat that, in warm climates, must then be removed from the building by ventilation or air conditioning. In colder climates where heating and lighting is required during the cold and dark winter months, halogen lamps are usually much smaller than standard incandescents, because for successful operation a bulb temperature over 200 °C is generally necessary

Gutenberg Bible
–
The Gutenberg Bible was the first major book printed using mass-produced movable metal type in Europe. It marked the start of the Gutenberg Revolution and the age of the book in the West. Widely praised for its aesthetic and artistic qualities, the book has an iconic status. Written in Latin, the Catholic Gutenberg Bible is an edition of the Vulgate, printed by Johannes Gutenberg, in Mainz, in present-day Germany, in the 1450s. Since its publication,49 copies have survived, and they are considered to be among the most valuable books in the even though no complete copy has been sold since 1978. In March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, being displayed to promote the edition and it is not known how many copies were printed, with the 1455 letter citing sources for both 158 and 180 copies. The 36-line Bible, believed to be the second printed version of the Bible, is sometimes referred to as a Gutenberg Bible. The Gutenberg Bible, an edition of the Vulgate, contains the Latin version of the Hebrew Old Testament and it is mainly the work of Jerome who began his work on the translation in 380 AD, with emendations from the Parisian Bible tradition, and further divergences. The Bible was not Gutenbergs first work, preparation of the Bible probably began soon after 1450, and the first finished copies were available in 1454 or 1455. It is not known exactly how long the Bible took to print, the first precisely datable printing is the Gutenbergs 31-line Indulgence which is known to already exist on 22 October 1454. Gutenberg made three significant changes during the printing process, the first sheets were rubricated by being passed twice through the printing press, using black and then red ink. This was soon abandoned, with spaces being left for rubrication to be added by hand, some time later, after more sheets had been printed, the number of lines per page was increased from 40 to 42, presumably to save paper. Therefore, pages 1 to 9 and pages 256 to 265, page 10 has 41, and from there on the 42 lines appear. The increase in number was achieved by decreasing the interline spacing. Finally, the print run was increased, necessitating resetting those pages which had already been printed, the new sheets were all reset to 42 lines per page. Consequently, there are two settings in folios 1-32 and 129-158 of volume I and folios 1-16 and 162 of volume II. The most reliable information about the Bibles date comes from a letter, in March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, being displayed to promote the edition, in Frankfurt. It is not known how many copies were printed, with the 1455 letter citing sources for both 158 and 180 copies

Italians
–
Italians are a nation and ethnic group native to Italy who share a common culture, ancestry and speak the Italian language as a native tongue. The majority of Italian nationals are speakers of Standard Italian. Italians have greatly influenced and contributed to the arts and music, science, technology, cuisine, sports, fashion, jurisprudence, banking, Italian people are generally known for their localism and their attention to clothing and family values. The term Italian is at least 3,000 years old and has a history that goes back to pre-Roman Italy. According to one of the common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú. 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 Etruscan civilization reached its peak about the 7th century BC, but by 509 BC, when the Romans overthrew their Etruscan monarchs, its control in Italy was on the wane. By 350 BC, after a series of wars between Greeks and Etruscans, the Latins, with Rome as their capital, gained the ascendancy by 272 BC, and they managed to unite the entire Italian peninsula. This period of unification was followed by one of conquest in the Mediterranean, in the course of the century-long struggle against Carthage, the Romans conquered Sicily, Sardinia and Corsica. Finally, in 146 BC, at the conclusion of the Third Punic War, with Carthage completely destroyed and its inhabitants enslaved, octavian, the final victor, was accorded the title of Augustus by the Senate and thereby became the first Roman emperor. After two centuries of rule, in the 3rd century AD, Rome was threatened by internal discord and menaced by Germanic and Asian invaders. Emperor Diocletians administrative division of the empire into two parts in 285 provided only temporary relief, it became permanent in 395, in 313, Emperor Constantine accepted Christianity, and churches thereafter rose throughout the empire. However, he moved his capital from Rome to Constantinople. The last Western emperor, Romulus Augustulus, was deposed in 476 by a Germanic foederati general in Italy and his defeat marked the end of the western part of the Roman Empire. During most of the period from the fall of Rome until the Kingdom of Italy was established in 1861, Odoacer ruled well for 13 years after gaining control of Italy in 476. Then he was attacked and defeated by Theodoric, the king of another Germanic tribe, Theodoric and Odoacer ruled jointly until 493, when Theodoric murdered Odoacer. Theodoric continued to rule Italy with an army of Ostrogoths and a government that was mostly Italian, after the death of Theodoric in 526, the kingdom began to grow weak

Christopher Columbus
–
Christopher Columbus was an Italian explorer, navigator, colonizer, and citizen of the Republic of Genoa. Under the auspices of the Catholic Monarchs of Spain, he completed four voyages across the Atlantic Ocean and those voyages and his efforts to establish permanent settlements on the island of Hispaniola initiated the European colonization of the New World. Western imperialism and economic competition were emerging among European kingdoms through the establishment of routes and colonies. During his first voyage in 1492, he reached the New World instead of arriving at Japan as he had intended, landing on an island in the Bahamas archipelago that he named San Salvador. Over the course of three voyages, he visited the Greater and Lesser Antilles, as well as the Caribbean coast of Venezuela and Central America. These voyages had, therefore, an impact in the historical development of the modern Western world. He spearheaded the transatlantic trade and has been accused by several historians of initiating the genocide of the Hispaniola natives. Columbus himself saw his accomplishments primarily in the light of spreading the Christian religion, Columbus never admitted that he had reached a continent previously unknown to Europeans, rather than the East Indies for which he had set course. He called the inhabitants of the lands that he visited indios, the name Christopher Columbus is the Anglicisation of the Latin Christophorus Columbus. His name in Italian is Cristoforo Colombo and, in Spanish and he was born before 31 October 1451 in the territory of the Republic of Genoa, though the exact location remains disputed. His father was Domenico Colombo, a wool weaver who worked both in Genoa and Savona and who also owned a cheese stand at which young Christopher worked as a helper. Bartolomeo, Giovanni Pellegrino, and Giacomo were his brothers, Bartolomeo worked in a cartography workshop in Lisbon for at least part of his adulthood. He also had a sister named Bianchinetta, Columbus never wrote in his native language, which is presumed to have been a Genoese variety of Ligurian. In one of his writings, he says he went to sea at the age of 10, in 1470, the Columbus family moved to Savona, where Domenico took over a tavern. In the same year, Christopher was on a Genoese ship hired in the service of René of Anjou to support his attempt to conquer the Kingdom of Naples. Some modern historians have argued that he was not from Genoa but, instead and these competing hypotheses have generally been discounted by mainstream scholars. In 1473, Columbus began his apprenticeship as business agent for the important Centurione, Di Negro, later, he allegedly made a trip to Chios, an Aegean island then ruled by Genoa. In May 1476, he took part in a convoy sent by Genoa to carry valuable cargo to northern Europe
