May 22 in History

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, appearing roughly every 74–79 years. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley.

The Sack of Damietta was a successful raid on the port city of Damietta on the Nile Delta by the Byzantine navy on 22–24 May 853. The city, whose garrison was absent at the time, was sacked and plundered, yielding not only many captives but also large quantities of weapons and supplies intended for the Arab Emirate of Crete. The Byzantine attack, which was repeated in the subsequent years, shocked the Abbasid authorities, and urgent measures were taken to refortify the coasts and strengthen the local fleet, beginning a revival of the Egyptian navy that culminated in the Tulunid and Fatimid periods.

The Order of Assassins was a Nizari Isma'ili Shia Islamic military order founded by Hasan-i Sabbah in 1090. Based in the Nizari Isma'ili state, which comprised a network of mountain castles in Persia and Syria, they conducted several high-profile assassinations throughout the Levant during the Crusades. The Assassins held a strict subterfuge policy in the region and are believed to have killed hundreds of people who were deemed enemies of their state over the course of 200 years, including other Shias, as well as Sunnis and Christians alike.

John (Christmastide 1166/7 – 19 October 1216) was King of England from 1199 until his death in 1216. He lost the Duchy of Normandy and most of his other French lands to King Philip II of France, resulting in the collapse of the Angevin Empire and contributing to the subsequent growth in power of the French Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of Magna Carta, a document considered a foundational milestone in English and later British constitutional history. John was the youngest son of King Henry II of England and Duchess Eleanor of Aquitaine. He was nicknamed John Lackland (Norman: Jean sans Terre, lit. 'John without land') because, as a younger son, he was not expected to inherit significant lands. He became Henry's favourite child after Henry faced a failed revolt from John's older brothers, Henry the Young King, Richard, and Geoffrey. Henry II appointed John Lord of Ireland in 1177 and gave him lands in England and on the continent. During the reign of his brother Richard I, John unsuccessfully attempted a rebellion against Richard's administrators while the King was participating in the Third Crusade, but he was proclaimed king after Richard died in 1199. Philip II of France agreed to recognise John's possession of the continental Angevin lands at the peace treaty of Le Goulet in 1200. When war with France broke out again in 1202, John achieved early victories, but shortages of military resources and his treatment of Norman, Breton, and Anjou nobles resulted in the collapse of his empire in northern France in 1204. He spent much of the next decade attempting to regain these lands, raising huge revenues, reforming his armed forces and rebuilding continental alliances. His judicial reforms had a lasting effect on the English common law system, as well as providing an additional source of revenue. His dispute with Pope Innocent III over the election of Stephen Langton as Archbishop of Canterbury led Innocent to ban church services in England from 1208 until 1214 and excommunicate John from 1209 until 1213. John's attempt to defeat Philip in 1214 failed because of the French victory over John's allies at the Battle of Bouvines. When he returned to England, John faced a rebellion by many of his barons, who were unhappy with his fiscal policies and his treatment of powerful English nobles. John and the barons agreed to Magna Carta as a peace treaty in 1215. However, neither side complied with its conditions. Civil war erupted shortly afterwards, with the barons aided by Philip's son Louis, and soon descended into a stalemate. Amid the civil war, John died of dysentery in eastern England in late 1216; supporters of his son Henry III went on to achieve victory over Louis and the rebel barons the following year. Contemporary chroniclers were mostly critical of John's performance as king, and his reign has since been the subject of significant debate and periodic revision by historians from the 16th century onwards. Historian Jim Bradbury has summarised the current historical opinion of John's positive qualities, observing that John is today usually considered a "hard-working administrator, an able man, an able general". Nonetheless, modern historians agree that he also had many faults as king, including what historian Ralph Turner describes as "distasteful, even dangerous personality traits", such as pettiness, spitefulness, and cruelty. These negative qualities provided extensive material for fiction writers in the Victorian era, and John remains a recurring character within Western popular culture, primarily as a villain in Robin Hood folklore.

Henry Raspe (German: Heinrich Raspe; c. 1204 – 16 February 1247) was the Landgrave of Thuringia from 1231 until 1239 and again from 1241 until his death. In 1246, with the support of the Papacy, he was elected King of Germany in opposition to Conrad IV, but his contested reign lasted a mere nine months.

The Kingdom of Serbia, also known by historical exonym Rascia, was a medieval Serbian kingdom in Southern Europe comprising most of what is today Serbia, Kosovo, and Montenegro, as well as southeastern Bosnia and Herzegovina, parts of coastal Croatia south of the Neretva river, Albania north of the Drin River, North Macedonia, and a small part of western Bulgaria.

The Brussels massacre was an antisemitic episode in Brussels (then within the Duchy of Brabant) in 1370 in connection with an alleged host desecration at the Brussels synagogue. In May 1370, a number of Jews, variously given as six or about twenty, were executed or otherwise killed, while the rest of the small community was banished. Many Jews from then on migrated further east to both modern day Germany and the Polish–Lithuanian Commonwealth. The supposedly recovered hosts became objects of veneration for local Christians as the Sacrament of Miracle. The cult survived until after the Second World War and the Holocaust, after which its antisemitic elements pushed the local church to derecognise it. It was claimed that the hosts had been stabbed by Jews and had miraculously shed blood, but been otherwise unharmed. The reliquary (without the hosts) is currently preserved in the cathedral's treasury (the hosts may have been present inside it as late as the year 2000).

Pope Gregory XI (Latin: Gregorius XI; born Pierre Roger de Beaufort; c. 1329 – 27 March 1378) was head of the Catholic Church from 30 December 1370 to his death, in March 1378. He was the seventh and last Avignon pope and the most recent French pope. In 1377, Gregory XI returned the papal court to Rome, ending nearly 70 years of papal residency in Avignon, in modern-day France. His death was swiftly followed by the Western Schism involving two Avignon-based antipopes.

The Wars of the Roses, known at the time and in the following centuries as the Civil Wars, were a series of armed confrontations, machinations, battles and campaigns fought for control of the English throne from 1455 to 1487. The conflict was fought between supporters of the House of York (whose emblem was a white rose) and the House of Lancaster (whose emblem, by 1485, was a red rose), two rival cadet branches of the royal House of Plantagenet. The conflict resulted in the end of Lancaster's male line in 1471, leaving the Tudor family to inherit, through the female line, the Lancaster claim to the throne. The conflict was largely brought to an end upon the union of the two houses through marriage, creating the Tudor dynasty that would subsequently rule England. The Wars of the Roses were rooted in English socio-economic troubles caused by the Hundred Years' War (1337–1453) with France, as well as the quasi-military bastard feudalism resulting from the powerful duchies created by King Edward III (died 1377). The mental instability of the House of Lancaster's King Henry VI (first reign: 1422 to 1461) revived his cousin Richard of York, 3rd Duke of York's interest in a claim to the throne. Warfare began in 1455 with York's capture of Henry at the First Battle of St Albans, upon which York was appointed Lord Protector by Parliament. Fighting resumed four years later when Yorkists led by Richard Neville, Earl of Warwick, captured Henry again, at the Battle of Northampton. After attempting to seize the throne, York was killed at the Battle of Wakefield, and his son Edward inherited his claim per the controversial Act of Accord. The Yorkists lost custody of Henry in 1461 after the Second Battle of St Albans, but defeated the Lancastrians at the Battle of Towton. The Yorkist Edward IV was formally crowned in June 1461. In 1464, Edward married Elizabeth Woodville against Warwick's advice, and reversed Warwick's policy of seeking closer ties with France. Warwick rebelled against Edward in 1469, leading to Edward's imprisonment after Warwick's supporters defeated a Yorkist army at the Battle of Edgcote. Edward was allowed to resume his rule after Warwick failed to replace him with Edward's brother George of Clarence. Within a year, Warwick launched an invasion of England alongside Henry VI's wife, Margaret of Anjou. Edward fled to Flanders, and Henry VI was restored as king in 1470. Edward mounted a counter-invasion with aid from Burgundy a few months later and killed Warwick at the Battle of Barnet. Henry was imprisoned again, and his sole heir was later killed by Edward at the Battle of Tewkesbury, followed by Henry's own death in the Tower of London, possibly on Edward's orders. Edward ruled unopposed for the next twelve years, during which England enjoyed a period of relative peace. Upon his death in 1483, he was succeeded by his twelve-year-old son, Edward V, who reigned for 78 days, before being deposed by his uncle Richard. Richard III assumed the throne amid controversies regarding the disappearance of Edward IV's two sons. He was met with a short-lived but major revolt and a wave of Yorkist defections. Amid the chaos, Henry Tudor, a descendant of Edward III through Lady Margaret Beaufort and a veteran Lancastrian, returned from exile with an army and defeated and killed Richard at the Battle of Bosworth Field in 1485. Tudor then assumed the English throne as Henry VII and united the rival houses by marrying Elizabeth of York, Edward IV's eldest daughter and heir. The wars concluded in 1487, with Henry VII's defeat of the remaining Yorkist opposition at Stoke Field. The House of Tudor would rule England until 1603, a period that saw the strengthening of the monarchy and the end of the medieval period in England

The Massacre in the Great Temple, also called the Toxcatl Massacre, or the Alvarado Massacre, was an event on 22 May 1520, in the Mexica, also known as the Aztec, capital of Tenochtitlan during the Spanish conquest of the Aztec Empire, in which the celebration of the Feast of Toxcatl ended in a massacre of Mexica elites. In late April of 1520, Cuban Governor Diego Velázquez de Cuéllar ordered Spanish conquistador, Pánfilo de Narváez, to arrest Hernán Cortés while he was in Tenochtitlan. Cortés heard about Narváez coming from Cuba, so he and some of his army left the city of Tenochtitlan to fight them. Before he departed, he entrusted one of his captains, Pedro de Alvarado, with governing both the Spanish and Mexica. During his absence, the Mexica emperor Moctezuma, also known as Montezuma, asked Alvarado for permission to celebrate the festival of Toxcatl, a Mexica festivity in honor of Tezcatlipoca, one of their main gods. Moctezuma had previously gotten authorization to celebrate the festival of Toxcatl from Cortés. However, Alvarado suspected that the Mexica were using Toxcatl as cover for a rebellion against the Spaniards. After the festivities had started, Alvarado turned on the Mexica, killing performers, spectators, and nobles celebrating inside Tenochtitlan's Great Temple. According to Mexica accounts, the Spanish blocked all exits and charged ferociously at the celebrants, killing indiscriminately. Spanish accounts of the massacre suggest several possible incitements, some saying the Mexica wanted to reclaim the gold the Spaniards had taken, and others blaming Narváez for causing Cortés' abrupt departure. The Mexica also say the Spaniards openly coveted the gold the Mexica were wearing, prompting a Mexica rebellion against the orders of Moctezuma. Although Alvarado's motive was debated, all accounts agree that the Mexica at the feast were mostly unarmed and the massacre was not directly provoked, and occurred with no warning. There were already tensions between the Mexica and the occupying Spaniards, who were holding Moctezuma prisoner. When Cortés and his men returned, the Mexica drove the Spaniards out of the city on the so-called the Sad Night (La Noche Triste), losing most of their men in battle or as prisoners who were then sacrificed.

The Holy Roman Emperor, originally and officially the Emperor of the Romans (Latin: Imperator Romanorum; German: Kaiser der Römer) during the Middle Ages, and also known as the Roman-German Emperor since the early modern period (Latin: Imperator Germanorum; German: Römisch-deutscher Kaiser), was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of King of Italy (Rex Italiae) from the 8th to the 16th century, and, almost without interruption, with the title of King of Germany (Rex Teutonicorum, lit. 'King of the Teutons') throughout the 12th to 18th centuries. The Holy Roman Emperor title provided the highest prestige among medieval Catholic monarchs, because the empire was considered by the Catholic Church to be the only successor of the Roman Empire during the Middle Ages and the early modern period. Thus, in theory and diplomacy, the emperors were considered primus inter pares—first among equals—among other Catholic monarchs across Europe. From an autocracy in Carolingian times (AD 800–924), the title by the 13th century evolved into an elective monarchy, with the emperor chosen by the prince-electors. Various royal houses of Europe, at different times, became de facto hereditary holders of the title, notably the Ottonians (962–1024), the Salians (1027–1125) and the Hohenstaufen (1138–1254). Following the late medieval crisis of government, the Habsburgs kept possession of the title (with only one interruption) from 1452 to 1806. The final emperors were from the House of Habsburg-Lorraine, from 1765 to 1806. The Holy Roman Empire was dissolved by Francis II, after a devastating defeat by Napoleon at the Battle of Austerlitz. The emperor was widely perceived to rule by divine right, though he often contradicted or rivaled the Pope, most notably during the Investiture controversy. The Holy Roman Empire never had an empress regnant, though women such as Theophanu and Maria Theresa exerted strong influence. Throughout its history, the position was viewed as a defender of the Catholic faith. Until Maximilian I in 1508, the Emperor-elect (Imperator electus) was required to be crowned by the pope before assuming the imperial title. Charles V was the last to be crowned by the Pope in 1530. There were short periods in history when the electoral college was dominated by Protestants, and the electors usually voted in their own political interest. However, even after the Reformation, the elected emperor was always a Catholic.

Prussia was a German state centred on the North European Plain. It originated from the 1525 secularization act of the Prussian part of the State of the Teutonic Order. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany. Prussia formed the German Empire when it united the German states in 1871. It was de facto dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and de jure by an Allied decree in 1947.

The Trevi Fountain (Italian: Fontana di Trevi) is an 18th-century fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Giuseppe Pannini in 1762. Standing 26.3 metres (86 ft) high and 49.15 metres (161.3 ft) wide, it is the largest Baroque fountain in the world and one of the most famous fountains in the world.

The 1766 Istanbul earthquake was a strong earthquake with epicenter in the eastern part of the Sea of Marmara, in the Çınarcık Basin (or near the Princes' Islands, north of the basin) which occurred in the early hours of Thursday morning, 22 May 1766. The earthquake had an estimated magnitude of 7.1 on the surface-wave magnitude scale, and caused effects in a vast area extending from Izmit to Rodosto (now Tekirdağ). In this area, the earthquake was followed by a tsunami which caused significant damage. The earthquake of 1766 was the last major earthquake to rock Istanbul because of a rupture of the North Anatolian Fault in the Marmara region.

The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark, along with 30 others, set out from Camp Dubois (Camp Wood), Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, ending six months later on September 23. President Thomas Jefferson commissioned the expedition, shortly after the Louisiana Purchase of 1803, to explore and detail as much of the new territory as possible. Furthermore, he wished to find a practical travel route across the western half of the continent—directly avoiding the hot and desolate desert southwest—and to establish an American presence in the new lands before European powers attempted to establish claims of their own. The campaign's secondary objectives were scientific, economical and humanitarian, i.e., to document the West's biodiversity, topography and geography and to establish positive trade relations with (potentially unknown) Native American tribes. The expedition returned to St. Louis to report their findings to President Jefferson via maps, sketches, and various journals.

In the Battle of Aspern–Essling (21–22 May 1809), Napoleon crossed the Danube near Vienna, but the French and their allies were attacked and forced back across the river by the Austrians under Archduke Charles. It was the first time Napoleon had been personally defeated in a major battle, as well as his first battle defeat in 10 years since the siege of Acre, and his first battle defeat as head of state, although he did suffer a tactical defeat in the Battle of Caldiero and in the Second Battle of Bassano. Archduke Charles drove out the French but fell short of destroying their army. The French lost approximately 23,000 men, including one of Napoleon's ablest field commanders and closest friends, Marshal Jean Lannes.

Littleport is a town in East Cambridgeshire, in the Isle of Ely, Cambridgeshire, England. It lies about 6 miles (10 km) north-east of Ely and 6 miles (10 km) south-east of Welney, on the Bedford Level South section of the River Great Ouse, close to Burnt Fen and Mare Fen. It is served by Littleport railway station. There are two primary schools, Millfield Primary and Littleport Community, and a secondary, Vista Academy. The Littleport riots of 1816 influenced the passage of the Vagrancy Act 1824.

SS Savannah was an American hybrid sailing ship/sidewheel steamer built in 1818. She was the first steamship to cross the Atlantic Ocean, transiting mainly under sail power from May to June 1819. In spite of this historic voyage, the great space taken up by her large engine and its fuel at the expense of cargo, and the public's anxiety over embracing her revolutionary steam power, kept Savannah from being a commercial success as a steamship. Originally laid down as a sailing packet, she was, following a severe and unrelated reversal of the financial fortunes of her owners, converted back into a sailing ship shortly after returning from Europe. Savannah was wrecked off Long Island, New York in 1821. No other American-owned steamship would cross the Atlantic for almost thirty years after Savannah's pioneering voyage. Two British sidewheel steamships, Brunel's SS Great Western and Menzies' SS Sirius, raced to New York in 1838, both voyages being made under steam power alone.

HMS Beagle was a Cherokee-class 10-gun brig-sloop of the Royal Navy, one of more than 100 ships of this class. The vessel, constructed at a cost of £7,803, was launched on 11 May 1820 from the Woolwich Dockyard on the River Thames. Later reports say the ship took part in celebrations of the coronation of George IV, passing under the old London Bridge, and was the first rigged man-of-war afloat upriver of the bridge. There was no immediate need for Beagle, so she "lay in ordinary", moored afloat but without masts or rigging. She was then adapted as a survey barque and took part in three survey expeditions.

The Associated Press (AP) is an American not-for-profit news agency headquartered in New York City. Founded in 1846, it operates as a cooperative, unincorporated association, and produces news reports that are distributed to its members, major U.S. daily newspapers and radio and television broadcasters. Since the Pulitzer Prize was established in 1917, the AP has earned 60 of them, including 36 for photography. The AP distributes its widely used AP Stylebook, its AP polls tracking NCAA sports, and its election polls and results during U.S. elections. It sponsors the National Football League's annual awards. In 2016, news collected by the AP was published and republished by more than 1,300 newspapers and broadcasters. The AP operates 235 news bureaus in 94 countries, and publishes in English, Spanish, and Arabic. It also operates the AP Radio Network, which provides twice hourly newscasts and daily sportscasts for broadcast and satellite radio and television stations. Many newspapers and broadcasters outside the United States are AP subscribers, paying a fee to use AP material without being contributing members of the cooperative. As part of their cooperative agreement with the AP, most member news organizations grant automatic permission for the AP to distribute their local news reports. As of 2025, the AP attracts more than 128 million monthly website visits, making it one of the top 10 news websites in the U.S.

The president of the United States (POTUS) is the head of state and head of government of the United States. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.

The United States House of Representatives is a chamber of the bicameral United States Congress; it is the lower house, with the United States Senate being the upper house. Together, the House and Senate have the authority under Article One of the Constitution of the United States in enumerated matters to pass or defeat federal legislation, known as bills. Those that are also passed by the Senate are sent to the president for signature or veto. The House's exclusive powers include initiating all revenue bills, impeaching federal officers, and electing the president if no candidate receives a majority of votes in the Electoral College.

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States. The South saw slavery as threatened because of the election of Abraham Lincoln as US president in 1860 and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the national abolition of slavery, freeing four million African Americans. Decades of controversy over slavery came to a head when Lincoln, a Republican who opposed slavery's expansion, won the 1860 presidential election. Seven slave states in the South responded to Lincoln's victory by seceding from the United States and forming the Confederate States of America. The Confederacy seized US forts and other federal assets in the South. The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina. A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president, Jefferson Davis, the Confederacy comprised eleven states, containing a third of the US population. Four years of intense combat, mostly in the South, ensued. During 1861–1862 in the western theater, the Union made permanent gains, though in the eastern theater the conflict was inconclusive. The abolition of slavery became a Union war goal on January 1, 1863, when Lincoln issued the Emancipation Proclamation, which declared all slaves in rebel states to be free, applying to more than 3.5 million of the 4 million enslaved people in the country. To the west, the Union first destroyed the Confederacy's river navy by the summer of 1862, then much of its western armies, and seized New Orleans. The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River, while Confederate general Robert E. Lee's incursion north failed at the Battle of Gettysburg. General Ulysses S. Grant's western successes led Lincoln to promote him to command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports, the Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union general William Tecumseh Sherman, followed by his March to the Sea, which culminated in his taking Savannah. The last significant battles raged around the ten-month siege of Petersburg, gateway to the Confederate capital of Richmond. The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following the Battle of Appomattox Court House, setting in motion the end of the war. Lincoln lived to see this victory but was shot by an assassin on April 14, dying the next day. By the end of the war, much of the South's infrastructure had been destroyed. The Confederacy collapsed, the Thirteenth Amendment abolished slavery, and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild the country, bring the former Confederate states back into the United States, and grant civil rights to freed slaves. The war is one of the most extensively studied and written about episodes in the history of the United States. It remains the subject of cultural and historiographical debate. Of continuing interest is the myth of the Lost Cause of the Confederacy. The war was among the first to use industrial warfare. Railroads, the electrical telegraph, steamships, the ironclad warship, and mass-produced weapons were widely used. The war left an estimated 700,000 soldiers dead, along with an undetermined number of civilian deaths, making it the deadliest in American history. The technology and brutality of the Civil War foreshadowed the coming world wars.

During the American Civil War, the United States Army, the land force that fought to preserve the collective Union of the states, was often referred to as the Union army, Federal army, or Northern army. It proved essential to the restoration and preservation of the United States as a working, viable republic. The Union army was made up of the permanent regular army of the United States, but further fortified, augmented, and strengthened by the many temporary units of dedicated volunteers, as well as including those who were drafted in to service as conscripts. To this end, the Union army fought and ultimately triumphed over the efforts of the Confederate States Army. Over the course of the war, 2,128,948 men enlisted in the Union army, including 178,895, or about 8.4% being colored troops; 25% of the white men who served were immigrants, and a further 18% were second-generation Americans. 596,670 Union soldiers were killed, wounded or went missing during the war. The initial call-up in 1861 was for just three months, after which many of these men chose to reenlist for an additional three years.

Oliver Fisher Winchester (November 30, 1810 – December 10, 1880) was an American businessman and politician, best known as being the founder of the Winchester Repeating Arms Company.

The Reconstruction era, often simply called Reconstruction, was a period in United States history that followed the American Civil War (1861–1865) and was dominated by the legal, social, and political challenges of the abolition of slavery and federal control over, and reintegration of, the former Confederate States into the United States. Three amendments were added to the United States Constitution to grant citizenship and equal civil rights to the newly freed slaves. To circumvent these, former Confederate states imposed poll taxes and literacy tests and sought to intimidate and control the Black population and discourage or prevent them from voting.

The Messa da Requiem is a musical setting of the Catholic funeral mass (Requiem) for four soloists, double choir and orchestra by Giuseppe Verdi. It was composed in memory of Alessandro Manzoni, whom Verdi admired, and is therefore also referred to as the Manzoni Requiem. The first performance, at the San Marco church in Milan on 22 May 1874, conducted by the composer, marked the first anniversary of Manzoni's death. It was followed three days later by the same performers at La Scala. Verdi conducted his work at major venues in Europe. Verdi composed the music for the last part of the text, Libera me, first, as his contribution to the Messa per Rossini, which he had begun after Gioachino Rossini had died. Considered too operatic to be performed in a liturgical setting, the Requiem is usually given in concert form; a performance lasts around 90 minutes. Musicologist David Rosen calls it "probably the most frequently performed major choral work composed after Mozart's Requiem".

The sultans of the Ottoman Empire, who were all members of the Ottoman dynasty, ruled over the transcontinental empire from its perceived inception in 1299 to its dissolution in 1922. At its height, the Ottoman Empire spanned an area from Hungary in the north to Yemen in the south and from Algeria in the west to Iraq in the east. Administered at first from the city of Söğüt from before 1280 and then from the city of Bursa from 1323 or 1324, the empire's capital was moved to Adrianople in 1363 following its conquest by Murad I and then to Constantinople in 1453 following its conquest by Mehmed II.

The Wright brothers, Orville Wright and Wilbur Wright, were American aviation pioneers who researched, invented, built, and flew the world's first successful airplane. They made the first controlled, sustained flight of an engine-powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, four miles (6 km) south of Kitty Hawk, North Carolina, at what is now known as Kill Devil Hills. In 1904 the Wright brothers developed the Wright Flyer II, which made longer-duration flights including the first circle, followed in 1905 by the first truly practical fixed-wing aircraft, the Wright Flyer III.

Lassen Peak, commonly referred to as Mount Lassen, is a 10,457-foot (3,187 m) lava dome volcano in Lassen Volcanic National Park in Northern California. Located in the Shasta Cascade region above the northern Sacramento Valley, it is the southernmost active volcano in the Cascade Range of the Western United States, and part of the Cascade Volcanic Arc stretching from southwestern British Columbia to Northern California. It supports many flora and fauna among its diverse habitats, which reach high elevations and are subject to frequent snowfall.

A multi-train rail crash occurred on 22 May 1915 outside the Quintinshill signal box near Gretna Green in Dumfriesshire, Scotland. It resulted in the deaths of over 200 people and remains the worst rail disaster in British history.

The British Army during the First World War fought the largest and most costly war in its long history. Unlike the French and German Armies, the British Army was made up exclusively of volunteers, as opposed to conscripts, at the beginning of the conflict. Furthermore, the British Army was considerably smaller than its French and German counterparts. During the First World War, there were four distinct British armies. The first comprised approximately 247,000 soldiers of the regular army, over half of whom were posted overseas to garrison the British Empire, supported by some 210,000 reserves and a potential 60,000 additional reserves.

Chiang Kai-shek was a Chinese military commander, revolutionary, and statesman who was President of the Republic of China from 1948 to 1975 and the head of the Nationalist government from 1925 to 1948. As the de facto leader of the Republic of China (ROC), he ruled the country through World War II and oversaw the relocation of its government to Taiwan following defeat in the Chinese Civil War.

Xining is the capital and most populous city of Qinghai province in western China and the largest city on the Tibetan Plateau. As of the 2020 census, it had 2,467,965 inhabitants, of whom 1,954,795 lived in the built-up area made of 5 urban districts. The city lies in the Huangshui River Valley, also known as Tsongkha, and owing to its high altitude, has a cool climate on the borderline between cool semi-arid and dry winter humid continental.

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.

The history of Mexico encompasses over 13,000 years between the initial migration of indigenous peoples and the modern day. Central and southern Mexico saw the rise and fall of complex indigenous civilizations such as the Olmecs, Mayas and Aztecs. Mesoamerican civilizations developed glyph based writing systems, recording the political history of conquests and rulers. Mesoamerican history prior to European arrival is variously called the pre-hispanic era and the pre-Columbian era. In the 16th Century, the Spanish conquest of the Aztec Empire resulted in the creation of New Spain and the introduction of Christianity. Following Mexico's independence from Spain in 1821, the country faced numerous challenges including conflicts between 'strongmen' or caudillos the Mexican–American War, and the French invasion. In the early 19th century, Mexican Revolution resulted in the rise of the Institutional Revolutionary Party (PRI) which has served as the pre-eminent political party in the country until the modern day. Experiments with nationalization, reforms, and development projects resulted in the Mexican miracle during the 1940s to 1970s. Since then, Mexico has been defined by its incorporation into the North American Free Trade Agreement (NAFTA) in 1994, the Mexican peso crisis, and the Mexican drug war.
