March 5 in History

The Roman emperor was the ruler of the Roman Empire, starting with the granting of the title augustus to Octavian in 27 BC. The title of imperator, originally a military honorific, was usually used alongside caesar, originally a cognomen. When a given Roman is described as becoming emperor in English, it generally reflects his accession as augustus, and later as basileus. Early emperors also used the title princeps ("first one") alongside other Republican titles, notably consul and pontifex maximus. The legitimacy of an emperor's rule depended on his control of the Roman army and recognition by the Senate; an emperor would normally be proclaimed by his troops, by the Senate, or both. The first emperors reigned alone; later emperors would sometimes rule with co-emperors to secure the succession or to divide the administration of the empire between them. The office of emperor was thought to be distinct from that of a rex ("king"). Augustus, the first emperor, resolutely refused recognition as a monarch. For the first three hundred years of Roman emperors, efforts were made to portray the emperors as leaders of the Republic, fearing any association with the kings who ruled Rome prior to the Republic. From Diocletian, whose reformed tetrarchy divided the position into one emperor in the West and one in the East, emperors ruled in an openly monarchic style. Although succession was generally hereditary, it was only hereditary if there was a suitable candidate acceptable to the army and the bureaucracy, so the principle of automatic inheritance was not adopted, which often led to several claimants to the throne. Despite this, elements of the republican institutional framework (Senate, consuls, and magistrates) were preserved even after the end of the Western Empire. Constantine the Great, the first Christian emperor, moved the capital from Rome to Constantinople, formerly known as Byzantium, in 330 AD. Roman emperors had always held high religious offices, and some early emperors were even worshiped as gods, at least following their death when they were said to have become divine. Under Constantine, there arose the specifically Christian idea that the emperor was God's chosen ruler on earth, a special protector and leader of the Christian Church, a position later termed Caesaropapism. In practice, an emperor's authority on Church matters was frequently subject to challenge. In the later period, although theoretically one empire, there were two emperors, one in the east and one in the west. The Western Roman Empire collapsed in the late 5th century after multiple invasions by Germanic barbarian tribes, with no recognized claimant to Emperor of the West remaining after the death of Julius Nepos in 480. Instead, the Eastern emperor Zeno proclaimed himself as the sole emperor of a theoretically undivided Roman Empire (although in practice he had no authority in the West). The subsequent Eastern emperors ruling from Constantinople styled themselves as "Basileus of the Romans" (Ancient Greek: βασιλεύς Ῥωμαίων, Basileus Romaíon) but are often referred to in modern scholarship as Byzantine emperors. The papacy and Christianised Germanic kingdoms of the West acknowledged the Eastern emperors until the accession of Empress Irene in 797. After this, the papacy created a rival lineage of Roman emperors in western Europe, the Holy Roman Emperors, which ruled the Holy Roman Empire for most of the period between 800 and 1806. These emperors were never recognized in Constantinople and their coronations resulted in the medieval problem of two emperors. The last Eastern emperor was Constantine XI Palaiologos, who died during the Fall of Constantinople to the Ottoman Empire in 1453. After conquering the city, Ottoman sultans adopted the title "Caesar of the Romans" (kayser-i Rûm). A Byzantine group of claimant emperors existed in the Empire of Trebizond until its conquest by the Ottomans in 1461, although they have used a modified title since 1282.

Nasir Khusraw was an Iranian Isma'ili poet, philosopher, traveler, and missionary for the Isma'ili Fatimid Caliphate.

The Livonian Order was an autonomous branch of the Teutonic Order, formed in 1237. From 1435 to 1561, it was a member of the "Livonian Confederation".

Henry VII (28 January 1457 – 21 April 1509), also known as Henry Tudor, was King of England and Lord of Ireland from his seizure of the crown on 22 August 1485 until his death in 1509. He was the first monarch of the House of Tudor. Henry was the son of Edmund Tudor, 1st Earl of Richmond, and Lady Margaret Beaufort. His mother was a great-granddaughter of John of Gaunt (son of Edward III) who founded the Lancastrian cadet branch of the House of Plantagenet. Thus Henry's claim to the English throne was as the great-great-great-grandson of Edward III. Henry VII's father Edmund Tudor was the half-brother of the Lancastrian king Henry VI. Edmund died three months before his son was born, and Henry was raised by his uncle Jasper Tudor, a Lancastrian, and William Herbert, a supporter of the Yorkist branch of the House of Plantagenet. During Henry's early years, his uncles and the Lancastrians fought a series of civil wars against the Yorkist claimant, Edward IV. After Edward retook the throne in 1471, Henry spent 14 years in exile in Brittany. He attained the throne when his forces, supported by France and Scotland, defeated Richard III at the Battle of Bosworth Field. He was the last king of England to win his throne on the field of battle, defending it two years later at the Battle of Stoke Field to decisively end the Wars of the Roses (1455–1487). He strengthened his claim by marrying Elizabeth of York, Edward IV's daughter. Henry restored power and stability to the English monarchy following the civil war. He is credited with many administrative, economic and diplomatic initiatives. His supportive policy toward England's wool industry and his standoff with the Low Countries had long-lasting benefits to the English economy. He paid very close attention to detail, and instead of spending lavishly, he concentrated on raising new revenues. He stabilised the government's finances by introducing several new taxes. After his death, a commission found widespread abuses in the tax collection process. Henry reigned for nearly 24 years and was peacefully succeeded by his son, Henry VIII.

Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance polymath who formulated a model of the universe that placed the Sun rather than Earth at its center. The publication of Copernicus's model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making a pioneering contribution to the Scientific Revolution. Though a similar heliocentric model had been developed eighteen centuries earlier by Aristarchus of Samos, an ancient Greek astronomer, Copernicus likely arrived at his model independently. Copernicus was born and died in Royal Prussia, a semi-autonomous and multilingual region created within the Crown of the Kingdom of Poland from lands regained from the Teutonic Order after the Thirteen Years' War. A polyglot and polymath, he obtained a doctorate in canon law and was a mathematician, astronomer, physician, classics scholar, translator, governor, diplomat, and economist. From 1497 he was a Warmian Cathedral chapter canon. In 1517 he derived a quantity theory of money—a key concept in economics—and in 1519 he formulated an economic principle that later came to be called Gresham's law.

Antonio de Ulloa y de la Torre-Guiral (12 January 1716 – 3 July 1795) was a Spanish Navy officer. He spent much of his career in the Americas, where he carried out important scientific work that earned him a reputation as one of the major figures of the Enlightenment in Spain. As a military officer, Ulloa achieved the rank of vice admiral. He also served the Spanish Empire as an administrator in the Viceroyalty of Peru and as governor of Spanish Louisiana. At the age of nineteen, Ulloa joined the French Geodesic Mission to the Equator, which established that the shape of the Earth is an oblate spheroid, flattened at the poles, as predicted by Isaac Newton. The mission took more than eight years to complete, during which time Ulloa, in close collaboration with his fellow naval officer Jorge Juan, made many astronomical, natural, and social observations in South America. Ulloa and Juan also helped to organize the defense of the Peruvian coast against the English squadron of Commodore Anson, after the outbreak of the War of Jenkins' Ear in 1739. The reports of Ulloa's scientific findings during his time in South America earned him an international reputation. Notably, Ulloa published the first detailed observations of platinum, later identified as a new chemical element. Ulloa returned to Europe in 1745. He was elected as a fellow of the Royal Society of London in 1746, and as a foreign member of the Royal Swedish Academy of Sciences in 1751. From 1758 to 1764, Ulloa served as governor of Huancavelica, in Peru, and as superintendent of the mercury mines of the region. There, he fought unsuccessfully against the corruption of the local administration. Following the Seven Years' War, Ulloa became the first governor of Spanish Louisiana in 1766. His rule was strongly resisted by the French Creoles of New Orleans, who expelled him from the city during the Rebellion of 1768. Despite some controversies, Ulloa continued to serve in the Spanish Navy and ended his career as its chief of operations.

The Boston Massacre, known in Great Britain as the Incident on King Street, was a confrontation on March 5, 1770, in the prelude to the American Revolution in Boston, in what was then the colony of the Province of Massachusetts Bay. In the confrontation, nine British soldiers shot several in a crowd, estimated between 300 and 400, who were harassing them verbally and throwing various projectiles. Five American colonists were killed. The event was subsequently described as "a massacre" by Samuel Adams, Paul Revere, and other leading Patriots who later became central proponents of independence during the American Revolution and Revolutionary War. British troops had been stationed in the Province of Massachusetts Bay since 1768 in order to support Crown-appointed officials and to enforce unpopular legislation implemented by the British Parliament. Amid tense relations between the civilians and the soldiers, a mob formed around a British sentry and verbally abused him. He was eventually supported by seven additional soldiers, led by Captain Thomas Preston, who were hit by clubs, stones, and snowballs. Eventually, one soldier fired, prompting the others to fire without an order by Preston. The gunfire instantly killed three people and wounded eight others, two of whom later died of their wounds. The crowd eventually dispersed after acting governor Thomas Hutchinson promised an inquiry, but they reformed the next day, prompting the withdrawal of the troops to Castle Island. Eight soldiers, one officer, and four civilians were arrested and charged with murder, and they were defended in court by attorney, and future U.S. president, John Adams. Six of the soldiers were acquitted; the other two were convicted of manslaughter and sentenced to branding on the thumb, according to the law at that time. Depictions, reports, and propaganda about the event, notably the colored engraving The Bloody Massacre, heightened tensions throughout the Thirteen Colonies.

The Peninsular War (1808–1814) was fought in the Iberian Peninsula by the Iberian nations Spain and Portugal, along with the United Kingdom, against the invading and occupying forces of the First French Empire during the Napoleonic Wars. In Spain, it is considered to overlap with the Spanish War of Independence. It overlapped with the War of the Fifth Coalition (1809) and the War of the Sixth Coalition (1812–1814). The war can be said to have started when the French and Spanish armies invaded and occupied Portugal in 1807 by transiting through Spain, but it escalated in 1808 after Napoleonic France occupied Spain, which had been its ally. Napoleon Bonaparte forced the abdications of Ferdinand VII and his father Charles IV and then installed his brother Joseph Bonaparte on the Spanish throne and promulgated the Bayonne Constitution. Most Spaniards rejected French rule and fought a bloody war to oust them. The war on the peninsula lasted until the Sixth Coalition defeated Napoleon in 1814, and is regarded as one of the first wars of national liberation. It is also significant for the emergence of large-scale guerrilla warfare. In 1808, the Spanish army in Andalusia defeated the French at the Battle of Bailén, considered the first open-field defeat of the Napoleonic army on a European battlefield. Besieged by 70,000 French troops, a reconstituted national government, the Cortes—in effect a government-in-exile—fortified itself in the secure port of Cádiz in 1810. The British army, under Arthur Wellesley, the future Duke of Wellington, guarded Portugal and campaigned against the French alongside the reformed Portuguese Army and provided whatever supplies they could get to the Spanish, while the Spanish armies and guerrillas tied down vast numbers of Napoleon's troops. In 1812, when Napoleon set out with a massive army on what proved to be a disastrous invasion of Russia, a combined allied army defeated the French at Salamanca and took the capital Madrid. In the following year the Coalition defeated King Joseph Bonaparte's army at the Battle of Vitoria, paving the way for victory in the war in the Iberian Peninsula. Pursued by the armies of Britain, Spain and Portugal, Marshal Jean-de-Dieu Soult, no longer getting sufficient support from a depleted France, led the exhausted and demoralized French forces in a fighting withdrawal across the Pyrenees during the winter of 1813–1814. The years of fighting in Spain were a heavy burden on France's Imperial Army. While the French won several battles they were eventually defeated, as their communications and supplies were severely tested and their units were frequently isolated, harassed or overwhelmed by Spanish partisans fighting an intense guerrilla war of raids and ambushes. The Spanish armies were repeatedly beaten and driven to the peripheries, but they would regroup and relentlessly hound and demoralize the French troops. This drain on French resources led Napoleon, who had unwittingly provoked a total war, to call the conflict the "Spanish ulcer". For France, the Peninsular War bogged down Napoleon's troops, which allowed the rest of Europe to challenge Napoleon once more, including in the War of the Fifth Coalition and the French invasion of Russia, and culminating in Napoleon's defeat in the War of the Sixth Coalition. The war against Napoleon's occupation led to the Spanish Constitution of 1812, promulgated by the Cortes of Cádiz, later a cornerstone of European liberalism. Though victorious in war—France would never again threaten a full-scale invasion of Spain—the burden of war destroyed the social and economic fabric of both Portugal and Spain, and the following civil wars between liberal and absolutist factions ushered in revolts in Spanish America that led to the independence of all of Spain's colonies on the American mainland, and the beginning of an era of social turbulence, increased political instability, and economic stagnation in Iberia itself.

The First Anglo-Burmese War (Burmese: ပထမအင်္ဂလိပ်-မြန်မာစစ်; [pətʰəma̰ ɪ́ɰ̃ɡəleiʔ-mjəmà sɪʔ]; 5 March 1824 – 24 February 1826), also known as the First Burma War in English language accounts and First English Invasion War (Burmese: ပထမအင်္ဂလိပ်ကျူးကျော်စစ်) in Burmese language accounts, was the first of three wars fought between the British and Burmese empires in the 19th century. The war, which began primarily over the control of what is now Northeastern India, ended in a costly but decisive British victory, giving the British total control of Assam, Cachar, Manipur and Jaintia as well as Arakan Province and Tenasserim. The Burmese submitted to a British demand to pay an indemnity of one million pounds sterling, and signed a commercial treaty. The war was one of the most expensive in British Indian history. 15,000 British soldiers died, together with an unknown number of Burmese military and civilian casualties. The high cost of the campaign to the British, 5–13 million pounds sterling (£400 million – £1.11 billion as of 2025) contributed to a severe economic crisis in British India which cost the East India Company its remaining privileges. Although once strong enough to threaten the interests of the British East India Company (especially with respect to the eastern border regions of Assam, Manipur, and Arakan), the Burmese Empire now suffered "the beginning of the end" of its status as an independent nation. They would be economically burdened for years to come by the cost of the indemnity. The British, eventually waging the Second and Third Anglo-Burmese Wars against a much-weakened Burma, would assume control of the entire country by 1885.

Roberto Cofresí y Ramírez de Arellano (June 17, 1791 – March 29, 1825), also known as El Pirata Cofresí, was a Puerto Rican pirate. He was born into a noble family, but the political and economic difficulties faced by the island as a colony of the Spanish Empire during the regional independence wars against the metropole meant that his household was poor. Cofresí worked at sea from an early age, which familiarized him with the region's geography, but provided him with only a modest salary. He eventually decided to abandon the sailor's life and become a pirate. He had previous links to land-based criminal activities, but the reason for Cofresí's change of vocation is unknown; historians speculate that he may have worked as a privateer aboard El Scipión, a ship owned by one of his cousins. At the height of his career, Cofresí evaded capture by vessels from Spain, Gran Colombia, the United Kingdom, Denmark, France, and the United States. He commanded several small-draft vessels, the best known a fast six-gun sloop named Anne, and he had a preference for speed and maneuverability over firepower. He manned them with small, rotating crews, which most contemporaneous documents numbered at 10 to 20. He preferred to outrun his pursuers, but his flotilla engaged the West Indies Squadron twice, attacking the schooners USS Grampus and USS Beagle. Most crew members were recruited locally, although men occasionally joined them from the other Antilles, Central America, and Europe. He never confessed to murder, but reportedly boasted about his crimes, and 300 to 400 people, mostly foreigners, died as a result of his pillaging. Cofresí proved too much for local authorities, who accepted international help to capture him. Spain created an alliance with the West Indies Squadron and the Danish government of Saint Thomas. On March 5, 1825, the alliance set a trap that forced Anne into a naval battle. After 45 minutes, Cofresí abandoned his ship and escaped overland; he was recognized by a resident who ambushed and injured him. Cofresí was captured and imprisoned, making a last unsuccessful attempt to escape by trying to bribe an official with part of a hidden stash. The pirates were sent to San Juan, Puerto Rico, where a brief military tribunal found them guilty and sentenced them to death. On March 29, 1825, Cofresí and most of his crew were executed by firing squad. He inspired stories and myths after his death, most emphasizing a Robin Hood-like "steal from the rich, give to the poor" philosophy which became associated with him. This portrayal has grown into legend, commonly accepted as fact in Puerto Rico and throughout the West Indies. Some of these claim that Cofresí became part of the Puerto Rican independence movement and other secessionist initiatives, including Simón Bolívar's campaign against Spain. Historical and mythical accounts of his life have inspired songs, poems, plays, books, and films. In Puerto Rico, caves, beaches, and other alleged hideouts or locations of buried treasure have been named after Cofresí, and a resort town is named for him near Puerto Plata in the Dominican Republic.

Samuel Colt (; July 19, 1814 – January 10, 1862) was an American inventor, industrialist, and businessman who established Colt's Patent Fire-Arms Manufacturing Company and made the mass production of revolvers commercially viable. Colt's first two business ventures were producing firearms in Paterson, New Jersey, and making underwater mines. His business expanded rapidly after 1847, when the Texas Rangers ordered 1,000 revolvers during the American war with Mexico. During the American Civil War, his factory in Hartford supplied firearms both to the North and the South. Later, his firearms were used widely during the settling of the western frontier. When Colt died in 1862, he was one of the wealthiest men in the United States. Colt's manufacturing methods were at the forefront of the Industrial Revolution. His use of interchangeable parts helped him become one of the first to make efficient use of the assembly line manufacturing process. Moreover, his innovative use of art, celebrity endorsements, and corporate gifts to promote his wares made him a pioneer in advertising, product placement, and mass marketing.

Britannia Bridge (Welsh: Pont Britannia) is a bridge in Wales that crosses the Menai Strait between the Isle of Anglesey and the city of Bangor. It was originally designed and built by the noted railway engineer Robert Stephenson as a tubular bridge of wrought iron rectangular box-section spans for carrying rail traffic. Its importance was to form a critical link of the Chester and Holyhead Railway's route, enabling trains to directly travel between London and the port of Holyhead, thus facilitating a sea link to Dublin, Ireland. Two decades before the building of the Britannia Bridge, the Menai Suspension Bridge had been completed, but this structure carried a road rather than track; there was no rail connection to Anglesey before the construction of the Britannia Bridge. After many years of deliberation and proposals, on 30 June 1845, a Parliamentary Bill covering the construction of the Britannia Bridge received royal assent. At the Admiralty's insistence, the bridge elements were required to be relatively high in order to permit the passage of a fully rigged man-of-war. In order to meet the diverse requirements, Stephenson, the project's chief engineer, performed in-depth studies on the concept of tubular bridges. For the detailed design of the structure's girders, Stephenson gained the assistance of distinguished engineer William Fairbairn. On 10 April 1846, the foundation stone for the Britannia Bridge was laid. The construction method used for the riveted wrought iron tubes was derived from contemporary shipbuilding practices; the same technique as used for the Britannia Bridge was also used on the smaller Conwy Railway Bridge. On 5 March 1850, Stephenson himself fitted the last rivet of the structure, marking the bridge's official completion. On 3 March 1966, the Britannia Bridge received Grade II listed status. A fire in May 1970 caused extensive damage to the Britannia Bridge. Subsequent investigation determined that the damage to the tubes was so extensive that they were not realistically repairable. The bridge was rebuilt in a quite different configuration, reusing the piers while employing new arches to support not one but two decks, as the new Britannia Bridge was to function as a combined road-and-rail bridge. The bridge was rebuilt in phases, initially reopening in 1972 as a single-tier steel truss arch bridge, carrying only rail traffic. Over the next eight years more of the structure was replaced, allowing for more trains to run and a second tier to be completed. The second tier was opened to accommodate road traffic in 1980. The bridge was subject to a £4 million four-month in-depth maintenance programme during 2011. Since the 1990s, there has been talk of increasing road capacity over the Menai Strait, either by extending the road deck of the existing bridge or via the construction of a third bridge.

Parma is a city in the region of Emilia-Romagna in northern Italy, known for its architecture, music, art, prosciutto (ham), cheese and surrounding countryside. With a population of 199,450 as of 2026, Parma is the second most populous city in Emilia-Romagna after Bologna, the region's capital.

Mefistofele (Italian pronunciation: [mefiˈstɔːfele]) is an Italian opera in a prologue and five acts, later reduced to four acts and an epilogue, the only completed opera with music by the Italian composer-librettist Arrigo Boito (there are several completed operas for which he was librettist only). It is an adaptation of the German legend of Faust. The opera was given its premiere on 5 March 1868 at La Scala, Milan, under the baton of the composer, despite his lack of experience and skill as a conductor. However, it was not a success and was immediately withdrawn after only two performances both of which were hissed at by the audiences. Revisions in 1875 resulted in success in Bologna and, with further adjustments in 1876 for Venice, the opera was performed elsewhere.

George Westinghouse Jr. (October 6, 1846 – March 12, 1914) was a prolific American inventor, engineer, and entrepreneurial industrialist based in Pittsburgh, Pennsylvania. He is best known for his creation of the railway air brake and for being a pioneer in the development and use of alternating current (AC) electrical power distribution. During his career, he received 360 patents for his inventions and established 61 companies, many of which still exist today. His invention of a train braking system using compressed air revolutionized the railroad industry around the world. He founded the Westinghouse Air Brake Company in 1869. He and his engineers also developed track-switching and signaling systems, which led to the founding of the company Union Switch & Signal in 1881. In the early 1880s, he developed inventions for the safe production, transmission, and use of natural gas. This sparked the creation of a whole new energy industry. During this same period, Westinghouse recognized the potential of using alternating current (AC) for electric power distribution. In 1886, he founded the Westinghouse Electric Corporation. Westinghouse's electric business directly competed with Thomas Edison's, who was promoting direct current (DC) electricity. Westinghouse Electric won the contract to showcase its AC system to illuminate the "White City" at the 1893 Columbian Exposition in Chicago. The company went on to install the world's first large-scale, AC power generation plant at Niagara Falls, New York, which opened in August 1895. Ironically, among many other honors, Westinghouse received the 1911 Edison Medal of the American Institute of Electrical Engineers "for meritorious achievement in connection with the development of the alternating current system".

The Moro Rebellion (1902–1913) was an armed conflict between the Moro people and the United States military during the Philippine–American War. The rebellion occurred after the conclusion of the conflict between the United States and the First Philippine Republic, and saw the US move to impose its authority over the Muslim states in Mindanao, Jolo, and the neighboring Sulu Archipelago.

The Italo-Turkish War (Turkish: Trablusgarp Savaşı, "Tripolitanian War", Italian: Guerra di Libia, "War of Libya"), also known as the Turco-Italian War, was fought between the Kingdom of Italy and the Ottoman Empire from 29 September 1911 to 18 October 1912. As a result of this conflict, Italy captured coastal areas of the Ottoman Tripolitania Vilayet, of which the main sub-provinces were Fezzan (Turkish: Fizan), Cyrenaica (Turkish: Sirenayka), and Tripoli (Turkish: Trablusgarp) itself. These territories became the colonies of Italian Tripolitania and Cyrenaica, which would later merge into Italian Libya. During the conflict, Italian forces also occupied the Dodecanese islands in the Aegean Sea. In the 1912 Treaty of Ouchy, which ended the war and gave Italy the possession of Libya, the Italians agreed to return the Dodecanese to the Ottoman Empire. However, the vagueness of the text, combined with subsequent adverse events unfavourable to the Ottoman Empire (the outbreak of the Balkan Wars and World War I), allowed a provisional Italian administration of the islands, and Turkey eventually renounced all claims on these islands in Article 122 of the Treaty of Sèvres (1920), confirmed by Article 15 of the 1923 Treaty of Lausanne. The war is considered a precursor of World War I. Members of the Balkan League, seeing how easily Italy defeated the Ottomans and motivated by incipient Balkan nationalism, attacked the Ottoman Empire in October 1912, starting the First Balkan War a few days before the end of the Italo-Turkish War. The Italo-Turkish War saw some technological changes, most notably the use of airplanes in combat. On 23 October 1911, an Italian pilot, Capitano Carlo Piazza, flew over Turkish lines on the world's first aerial reconnaissance mission, and on 1 November, the first aerial bomb was dropped by Sottotenente Giulio Gavotti, on Turkish troops in Libya, from an early model of Etrich Taube aircraft. The Turks, using rifles, were the first to shoot down an airplane. Another use of new technology was a network of wireless telegraphy stations established soon after the initial landings. Guglielmo Marconi, the inventor of wireless telegraphy, came to Libya to conduct experiments with the Italian Corps of Engineers.

The British Raj was the period of rule of the British Crown on the Indian subcontinent, lasting from 1858 to 1947. It is also called Crown rule in India, or direct rule in India. The region under British control was commonly called India in contemporaneous usage and included areas directly administered by the United Kingdom, which were collectively called British India, and areas ruled by indigenous rulers, but under British paramountcy, called the princely states. The region was sometimes called the Indian Empire, though not officially. As India, it was a founding member of the League of Nations and a founding member of the United Nations in San Francisco in 1945. India was a participating state in the Summer Olympics in 1900, 1920, 1928, 1932, and 1936.

Adolf Hitler (20 April 1889 – 30 April 1945) was an Austrian-born German politician who was dictator of Germany in the Nazi era from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor of Germany in 1933 and then taking the title of Führer und Reichskanzler in 1934. Germany's invasion of Poland on 1 September 1939 under his leadership marked the outbreak of the Second World War. Throughout the ensuing conflict, Hitler was closely involved in the direction of German military operations and was central to the perpetration of the genocide of about six million Jews in the Holocaust as well as the deaths of millions of other victims. Hitler was born in Braunau am Inn in Austria-Hungary and moved to Germany in 1913. He was decorated during his service in the German Army in the First World War, receiving the Iron Cross. In 1919, he joined the German Workers' Party (DAP), the precursor of the Nazi Party, and in 1921, was appointed the leader of the Nazi Party. In 1923, he attempted to seize governmental power in a failed coup in Munich and was sentenced to five years in prison, serving just over a year. While there, he dictated the first volume of his autobiography and political manifesto Mein Kampf ('my struggle'). After his early release in 1924, he gained popular support by attacking the Treaty of Versailles as well as promoting pan-Germanism, antisemitism, and anti-communism with charismatic oratory and Nazi propaganda. He frequently denounced communism as being part of an international Jewish conspiracy. Following elections to the Reichstag in November 1932, the Nazi Party held the most seats in the Reichstag ('parliament'), but not a majority. Subsequently, former chancellor Franz von Papen and other conservative politicians convinced Reichspräsident ('president') Paul von Hindenburg to appoint Hitler as chancellor on 30 January 1933. Shortly thereafter, on 23 March, the Reichstag passed the Enabling Act of 1933, which ultimately began the Weimar Republic's transformation into Nazi Germany. Upon Hindenburg's death on 2 August 1934, Hitler replaced him as head of state and thereafter Germany became a totalitarian dictatorship. Domestically, Hitler began to implement numerous racist policies, which marginalised and scapegoated German Jews. His first six years in power resulted in rapid economic recovery from the Great Depression, the abrogation of restrictions imposed on Germany after the First World War, and the annexation of territories inhabited by millions of ethnic Germans, which won him significant popularity. One of Hitler's key goals was Lebensraum ('living space') for the German people in Eastern Europe. His aggressive, expansionist foreign policy is considered the primary cause of World War II in Europe. On 1 September 1939, Hitler oversaw the German invasion of Poland, thereby causing Britain and France to declare war on Germany. After ordering an invasion of the Soviet Union in June 1941, he declared war on the United States in December of the same year. By the end of 1941, German forces and the European Axis powers occupied most of Europe and North Africa. These gains were gradually reversed after 1941 until the Allied forces defeated the German military in 1945. On 29 April 1945, Hitler married his longtime partner, Eva Braun, in the Führerbunker ('leader's bunker') in Berlin. They committed suicide the next day to avoid capture by the Soviet Red Army. The historian and biographer Ian Kershaw described Hitler as "the embodiment of modern political evil". Under Hitler's leadership and racist ideology, the Nazi regime was responsible for the genocide of an estimated six million Jews and millions of other victims, whom he and his followers deemed Untermenschen ('subhumans') or socially undesirable. Hitler and the Nazis were also responsible for the deliberate killing of an estimated 19.3 million civilians and prisoners of war. In addition, 28.7 million soldiers and civilians died as a result of military action in the European theatre. In absolute terms, the number of civilians killed during World War II was unprecedented in warfare, and the casualties make it the deadliest conflict in history.

The Spanish Civil War (Spanish: guerra civil española) was fought in Spain from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans loyal to the left-leaning Popular Front government of the Second Spanish Republic included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists, who established the military-led Spanish State and were directly aided by an intervention from Fascist Italy and participation of Nazi Germany. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or communism and fascism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975. The war began after the partial failure of the coup d'état of July 1936 against the Popular Front government by a group of generals of the Spanish Republican Armed Forces. They were supported by right-wing groups including the Christian traditionalist party CEDA; monarchists, including both the opposing Alfonsists and the religious conservative Carlists; and the Falange Española de las JONS, a fascist political party. However, rebelling units in almost all important cities did not gain control, leaving Spain militarily and politically divided. The Nationalists were initially led by a military junta, until General Francisco Franco was appointed supreme leader on 1 October 1936 of what he called the Spanish State. The rebellion was countered by the arming of left-wing social movements and parties, and the formation of militias. This led to rapid socioeconomic and political transformation in the Republican zone, referred to as the Spanish Revolution. The Nationalist forces received munitions, soldiers, and air support from Fascist Italy which conducted a large-scale intervention and Nazi Germany which sent its Condor Legion, while the Republican government received support from the Soviet Union and Mexico. Other countries, such as the United Kingdom, France, and the United States, continued to recognise the Republican government, but followed official policies of non-intervention. Despite this, tens of thousands of citizens from non-interventionist countries directly participated in the conflict, mostly in the pro-Republican International Brigades. Franco gradually emerged as the primary leader of the Nationalists, becoming the dictator of the Spanish State by 1937 and co-opting Falangism, gaining recognition as a fascist leader. The Nationalists advanced from their strongholds in the south and west, capturing most of Spain's northern coastline in 1937 and besieging Madrid. After much of Catalonia was captured in 1938 and 1939 and Madrid was cut off from Barcelona, the Republican military position became hopeless. On 5 March 1939, in response to allegedly increasing communist dominance of the Republican government and the deteriorating military situation, Colonel Segismundo Casado led a military coup against the Republican government, intending to seek peace with the Nationalists. These peace overtures, however, were rejected by Franco. Following internal conflict between Republican factions in Madrid in the same month, Franco entered the capital and declared victory on 1 April 1939. Hundreds of thousands of those associated with the Republicans fled Spain, mostly to refugee camps in southern France; many of those who stayed were persecuted by the victorious Nationalists. The war became notable for the passion and political division it inspired worldwide, and for the many atrocities that occurred. Organised purges occurred in territory captured by Franco's forces to consolidate power. Mass executions took place in areas controlled by the Republicans, with the participation of local authorities varying by location.

The Political Bureau of the Central Committee of the Communist Party of the Soviet Union, abbreviated as Politburo, was the de facto highest executive authority in the Communist Party of the Soviet Union (CPSU). While elected by and formally accountable to the Central Committee, in practice the Politburo operated as the ruling body of Soviet Russia and the Soviet Union from its creation in 1919 until the party's dissolution in 1991. Full members and candidate (non-voting) members held among the most powerful positions in the Soviet hierarchy, often overlapping with top state roles. Its duties, typically carried out at weekly meetings, included formulating state policy, issuing directives, and ratifying appointments.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many engaging in total war on an unprecedented scale. World War II was the deadliest conflict in history, causing the deaths of 60 to 75 million people, a majority of whom were civilians. Millions died as a result of massacres, starvation, disease, and genocides including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Workers' and Peasants' Red Army, often referred by its shortened name as the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army was renamed the "Soviet Army". Following the dissolution of the Soviet Union, it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army.

The Cold War was a period of international geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc. It began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

Joseph Stalin (born Ioseb Besarionis dze Jughashvili; 18 December 1878 – 5 March 1953) was a Soviet politician and revolutionary who ruled the Soviet Union from 1922 until his death in 1953, holding the titles of General Secretary of the Communist Party of the Soviet Union from 1922 to 1952 and the nation's Premier from 1941 to 1953. Initially presiding over an oligarchic one-party system that governed by plurality, he ultimately became the de facto dictator of the Soviet Union by the 1930s. Ideologically committed to the Leninist interpretation of Marxism, Stalin helped to formalise these ideas as Marxism–Leninism, while his own policies became known as Stalinism. Born into a poor Georgian family in Gori, Russian Empire, Stalin began his revolutionary career by joining the Marxist Russian Social Democratic Labour Party as a youth. There, he edited the party's newspaper, Pravda, and raised funds for Vladimir Lenin's Bolshevik faction via robberies, kidnappings, and protection rackets. Repeatedly arrested, he underwent several internal exiles. After the Bolsheviks seized power in Russia during the 1917 October Revolution, Stalin joined the party's governing Politburo, where he was instrumental in overseeing the Soviet Union's establishment in 1922. After Lenin fell ill and then died in 1924, Stalin assumed leadership over the country. During Stalin's rule, "Socialism in One Country" became a central tenet of the party's dogma, and Lenin's New Economic Policy was replaced with a centralized command economy. Under the Five-Year Plan system, the country underwent collectivisation and rapid industrialization but experienced significant disruptions in food production that contributed to the famine of 1932–33. To eradicate those regarded as "enemies of the working class", Stalin instituted the "Great Purge", in which over a million were imprisoned and at least 700,000 executed between 1934 and 1939. Stalin's government promoted Marxism–Leninism abroad through the Communist International and supported anti-fascist movements throughout Europe during the 1930s, particularly in the Spanish Civil War. In 1939, it signed a non-aggression pact with Nazi Germany, resulting in their joint invasion of Poland. Germany ended the pact by invading the Soviet Union in 1941. Despite initial setbacks, the Soviet Red Army repelled the German incursion and captured Berlin in 1945, ending World War II in Europe. The Soviets annexed the Baltic states and helped establish Soviet-aligned governments throughout Central and Eastern Europe, China and North Korea. The Soviet Union and the United States emerged from the war as the two world superpowers. Tensions arose between the Soviet-backed Eastern Bloc and U.S.-backed Western Bloc which became known as the Cold War. Stalin led his country through its post-war reconstruction, during which it developed a nuclear weapon in 1949. In these years, the country experienced another major famine and an antisemitic campaign peaking in the doctors' plot. Stalin died in 1953 and was eventually succeeded by Nikita Khrushchev, who denounced his predecessor and initiated a de-Stalinisation process throughout Soviet society. Widely considered one of the 20th century's most significant figures, Stalin was the subject of a pervasive personality cult within the international Marxist–Leninist movement, for whom Stalin was a champion of socialism and the working class. Since the dissolution of the Soviet Union in 1991, Stalin has retained popularity in Russia as a victorious wartime leader who established the Soviet Union as one of the world's leading great powers. Conversely, his totalitarian government has been widely condemned for overseeing mass repressions, ethnic cleansing, hundreds of thousands of executions, and famines which caused the deaths of millions.

The Sutton Wick air crash occurred on 5 March 1957 when a Blackburn Beverley C Mk 1 heavy transport aircraft, serial number XH117, of No. 53 Squadron RAF crashed at Sutton Wick, Drayton, Berkshire, England, following a shut-down of one engine and partial loss of power on another. Shortly after take-off, No. 1 engine was shut down as a precautionary measure then whilst on final approach back to RAF Abingdon, No. 2 engine failed to respond to throttle inputs. The aeroplane struck cables and trees 18 minutes after lifting off. Of 17 passengers and five crew aboard, all but four were killed in the accident. Two people on the ground were also killed. An investigation found that a non-return valve in the fuel system had been installed the wrong way round causing two of the engines to be starved of fuel. The technician found responsible for incorrectly fitting the valve was charged under the Air Force Act. Following the accident, the non-return valve was re-designed so it could not be installed incorrectly. Two RAF officers who took part in the rescue after the crash were highly praised for "refusing to give up while there was hope of finding survivors among the wreckage."

Patsy Cline (born Virginia Patterson Hensley; September 8, 1932 – March 5, 1963) was an American singer. One of the most influential vocalists of the 20th century, she was known as one of the first country music artists to successfully cross over into pop music. Cline had several major hits during her eight-year recording career, including two number-one hits on the Billboard Hot Country and Western Sides chart. Born in Winchester, Virginia, Cline's first professional performances began in 1948 at local radio station WINC when she was 15. In the early 1950s, Cline began appearing in a local band led by performer Bill Peer. Various local appearances led to featured performances on Connie B. Gay's Town and Country television broadcasts. She signed her first recording contract with the 4 Star label in 1954, and had minor success with her earliest 4 Star singles, including "A Church, a Courtroom, Then Goodbye" (1955) and "I've Loved and Lost Again" (1956). In 1957, Cline made her first national television appearance on Arthur Godfrey's Talent Scouts. After performing "Walkin' After Midnight", the single became her first major hit on both the country and pop charts. Cline's further singles with 4 Star Records were unsuccessful, although she continued performing and recording. In 1958, she relocated to Nashville, Tennessee, to further her career. Working with new manager Randy Hughes, Cline became a member of the Grand Ole Opry and then moved to Decca Records in 1960. Under the direction of producer Owen Bradley, her musical sound shifted, and she achieved consistent success. The 1961 single "I Fall to Pieces" became her first to top the Billboard country chart. Cline was severely injured in an automobile accident, which caused her to spend a month in the hospital. After she recovered, her next single, "Crazy", also became a major hit. During her final years, Cline had hits with "She's Got You", "When I Get Through with You", "So Wrong", and "Leavin' on Your Mind". She also toured and headlined shows with more frequency. On March 5, 1963, she was killed in the 1963 Camden PA-24 crash along with country musicians Cowboy Copas and Hawkshaw Hawkins, and manager Randy Hughes, during a flight from Kansas City, Kansas, back to Nashville. Since her death, Cline has been cited as one of the most celebrated, respected, and influential performers of the 20th century. Her music has influenced performers of various styles and genres. She has also been seen as a forerunner for women in country music, being among the first to sell records and headline concerts. In 1973, she became the first female performer to be inducted into the Country Music Hall of Fame. In the 1980s, Cline's posthumous successes continued in the mass media. She was portrayed twice in major motion pictures, including the 1985 biopic Sweet Dreams starring Jessica Lange. Several documentaries and stage shows about her have been made, including the 1988 musical Always...Patsy Cline. A 1991 box set of her recordings received critical acclaim. Her greatest-hits album sold over 10 million copies in 2005. In 2011, Cline's childhood home in Winchester was restored as a museum for visitors and fans to tour.
