393 Roman_emperor

Roman emperor Theodosius I proclaims his eight-year-old son Honorius co-emperor.

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 alongside other Republican titles, notably consul and pontifex maximus.
971 Crossbow

Using crossbows, Song dynasty troops soundly defeat a war elephant corps of the Southern Han at Shao.

A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun. Crossbows shoot arrow-like projectiles called bolts or quarrels. A person who uses a crossbow is called a crossbowman, an arbalister or an arbalist.
1229 Nousiainen

The episcopal seat is moved from Nousiainen to Koroinen (located near the current centre of Turku) by the permission of Pope Gregory IX.

The date is starting to be considered as the founding of Turku.
Nousiainen is a municipality of Finland. It is located in the Southwest Finland region, 20 kilometres (12 mi) from Turku along Highway 8 (E8). The Finnish-speaking municipality has a population of 4,667 (31 December 2025) and covers an area of 199.55 square kilometres (77.05 sq mi) of which 0.62 km2 (0.24 sq mi) is water. The population density is 23.46 inhabitants per square kilometre (60.8/sq mi).
1264 Henry III of England

In the conflict between King Henry III of England and his rebellious barons led by Simon de Montfort, King Louis IX of France issues the Mise of Amiens, a one-sided decision in favour of Henry that later leads to the Second Barons' War.

Henry III (1 October 1207 – 16 November 1272), also known as Henry of Winchester, was King of England, Lord of Ireland and Duke of Aquitaine from 1216 until his death in 1272. The son of John, King of England, and Isabella of Angoulême, Henry acceded to the throne when he was only nine in the middle of the First Barons' War. Cardinal Guala Bicchieri declared the war against the rebel barons to be a religious crusade and Henry's forces, led by William Marshal, defeated the rebels at the battles of Lincoln and Sandwich in 1217. Henry promised to abide by the Great Charter of 1225, a later version of Magna Carta (1215), which limited royal power and protected the rights of the major barons. Henry's early reign was dominated first by William Marshal, and after his death in 1219 by the magnate Hubert de Burgh, Earl of Kent. In 1230 the King attempted to reconquer the provinces of France that had once belonged to his father, but the invasion was a debacle. A revolt led by William Marshal's son Richard broke out in 1232, ending in a peace settlement negotiated by the Catholic Church. Following the revolt, Henry ruled England personally, rather than governing through senior ministers. He travelled less than previous monarchs, investing heavily in a handful of his favourite palaces and castles. He married Eleanor of Provence, with whom he had five children. He was known for his piety, holding lavish religious ceremonies and giving generously to charities; he was particularly devoted to the figure of Edward the Confessor, whom he adopted as his patron saint. He extracted huge sums of money from the Jews in England, ultimately crippling their ability to do business. As attitudes towards the Jews hardened, he later introduced the Statute of Jewry, which attempted to segregate the Jewish community from the English populace. In a fresh attempt to reclaim his family's lands in France, he invaded Poitou in 1242, leading to the disastrous Battle of Taillebourg. After this, he relied on diplomacy, cultivating an alliance with Frederick II, Holy Roman Emperor. He supported his brother Richard of Cornwall in his successful bid to become King of the Romans in 1256, but was unable to place his own son Edmund Crouchback on the throne of Sicily, despite investing large amounts of money. He planned to go on crusade to the Levant, but was prevented from doing so by rebellions in Gascony. By 1258, Henry's rule had grown increasingly unpopular due to the failure of his expensive foreign policies, the notoriety of his Poitevin half-brothers, and the role of his local officials in collecting taxes and debts. In response to this state of affairs, a coalition of his barons seized power in a coup d'état and expelled the Poitevins from England, reforming the royal government through a process called the Provisions of Oxford. In 1259, Henry and the baronial government consented to the Treaty of Paris, under which Henry gave up his rights to his other lands in France in return for King Louis IX recognising him as the rightful ruler of Gascony. Despite the ultimate collapse of the baronial regime, Henry was unable to reform a stable government and instability continued across England. In 1263 one of the more radical barons, Simon de Montfort, seized power, resulting in the Second Barons' War. Henry persuaded Louis to support his cause and mobilised an army. The Battle of Lewes was fought in 1264 when Henry was defeated and taken prisoner. Henry's eldest son, Edward, escaped from captivity to defeat Simon at the Battle of Evesham the following year and freed his father. Henry initially exacted a harsh revenge on the remaining rebels but was persuaded by the Church to mollify his policies through the Dictum of Kenilworth. Reconstruction was slow, and Henry had to acquiesce to several measures, including further suppression of the Jews, to maintain baronial and popular support. He died in 1272, leaving Edward as his successor. His body was buried in Westminster Abbey, which he had rebuilt in the second half of his reign, and was moved to his current tomb in 1290. Some miracles were declared after his death, but he was not canonised. His reign of 56 years was the longest in medieval English history and would not be surpassed by an English, or later British, monarch until that of George III in the 18th and 19th centuries.
1368 Hongwu Emperor

Zhu Yuanzhang proclaims himself the Hongwu Emperor, beginning the Ming dynasty.

The Hongwu Emperor (21 October 1328 – 24 June 1398), personal name Zhu Yuanzhang, was the founding emperor of the Ming dynasty of China, reigning from 1368 to 1398. Born in 1328 into a peasant family in Anhui, Zhu Yuanzhang grew up during a period of epidemics, famines, and widespread uprisings in China under the Mongol-led Yuan dynasty. When he was 16, his parents and brother died in an epidemic. The orphaned Zhu briefly lived as a novice monk, begging for alms and gaining insight into the hardships of the common people. He also developed a dislike for book-dependent scholars. In 1352, he joined the Red Turban rebels, a movement that sought to overthrow Yuan rule, and quickly rose to command his own army. He captured Nanjing in 1356 and built a powerful regional regime in southern China. He adopted Yuan administrative practices and applied them to his expanding territory. Although he nominally acknowledged the authority of the Red Turban figurehead Han Lin'er, Zhu increasingly acted independently and, after defeating rival rebels, declared himself King of Wu in 1364. After successfully dominating southern and central China in early 1368, Zhu decided to rename the Kingdom of Wu to Da Ming, which translates to 'Great Radiance'. He adopted Hongwu, meaning 'Vastly Martial', as his era name. In the following four-year war, he drove out the Mongol forces loyal to the Yuan dynasty and unified the country, but failed to conquer Mongolia. During the Hongwu Emperor's 30-year reign, Ming China experienced significant growth and recovered from the effects of prolonged wars. The Emperor had a strong understanding of the structure of society and believed in implementing reforms to improve institutions. This approach differed from the Confucian belief that the ruler's moral example was the most important factor. The Hongwu Emperor also prioritized the safety of his people and the loyalty of his subordinates, demonstrating pragmatism and caution in military affairs. He maintained a disciplined army and made efforts to minimize the impact of war on civilians. He died in 1398 and was succeeded by his grandson, the Jianwen Emperor. In 1402, the Hongwu Emperor's fourth son, Zhu Di, overthrew the Jianwen Emperor following a civil war and took the throne as the Yongle Emperor.
1546 François_Rabelais

Having published nothing for eleven years, François Rabelais publishes the Tiers Livre, his sequel to Gargantua and Pantagruel.

François Rabelais was a French writer who has been called the first great French prose author. A humanist of the French Renaissance and Greek scholar, he attracted opposition from both Protestant theologian John Calvin and from the hierarchy of the Catholic Church. Though in his day he was best known as a physician, scholar, diplomat, and Catholic priest, later he became better known as a satirist for his depictions of the grotesque, and for his larger-than-life characters.
1556 Earthquake

The deadliest earthquake in history, the Shaanxi earthquake, hits Shaanxi province, China.

The death toll may have been as high as 830,000.
An earthquake, also called a quake, tremor, or temblor, is the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy released per unit volume.
1565 Deccan_sultanates

The Deccan Sultanates defeat Rama Raya of the Vijayanagara Empire at the Battle of Talikota, resulting in over 100,000 casualties and the destruction of the capital Vijayanagara.

The Deccan sultanates is a historiographical term referring to five medieval Persianate Muslim kingdoms based in the Deccan Plateau between the Krishna River and the Vindhya Range. They emerged after the disintegration of the Bahmani Sultanate and were ruled by various dynasties: Ahmadnagar, Berar, Bidar, Bijapur, and Golconda. Ahmadnagar was the first to declare independence, in 1490; followed by Bijapur and Berar in the same year. Bidar became independent in c. 1492, and Golconda in 1512 CE.
1570 James Stewart, 1st Earl of Moray

James Stewart, 1st Earl of Moray, regent for the infant King James VI of Scotland, is assassinated by firearm, the first recorded instance of such.

James Stewart, 1st Earl of Moray (c. 1531 – 23 January 1570) was a member of the House of Stewart as the illegitimate son of James V of Scotland. At times a supporter of his half-sister Mary, Queen of Scots, he was the regent of Scotland for his half-nephew, the infant James VI, from 1567 until his assassination in 1570. He was the first head of government to be assassinated with a firearm.
1571 Royal Exchange, London

The Royal Exchange opens in London.

The Royal Exchange is a building in central London, built to house the London Stock Exchange, which now operates elsewhere. Today, the Royal Exchange contains restaurants and luxury shops. It was founded in the 16th century by the merchant Sir Thomas Gresham on the suggestion of his factor Richard Clough to act as a centre of commerce for the City of London. The site was provided by the City of London Corporation and the Worshipful Company of Mercers, who still jointly own the freehold. The original foundation was ceremonially opened by Queen Elizabeth I who granted it its "royal" title. Rebuilt in the 1840s, the current neoclassical building has a trapezoidal floor plan and is flanked by Cornhill and Threadneedle Street, which converge at Bank junction in the heart of the city. It lies in the Ward of Cornhill. The exchange building has twice been destroyed by fire and subsequently rebuilt. The present building was designed by Sir William Tite. The site also housed the Lloyd's insurance market for nearly 150 years. Traditionally, the steps of the Royal Exchange are the place where certain royal proclamations (such as the dissolution of parliament) are read out by either a herald or a crier. Following the death or abdication of a monarch and the confirmation of the next monarch's accession to the throne by the Accession Council, the Royal Exchange Building is one of the locations where a herald proclaims the new monarch's reign to the public.
1579

The Union of Utrecht forms a Protestant republic in the Netherlands.

The Union of Utrecht (Dutch: Unie van Utrecht) was an alliance based on an agreement concluded on 23 January 1579 between a number of Dutch provinces and cities, to reach a joint commitment against the king, Philip II of Spain. By joining forces, they hoped to force him to stop his harsh administrative measures. In addition, some important political matters were regulated in areas such as defence, taxation and religion, which is why the treaty in question is also seen as a first version or precursor of a later constitution. The Union of Utrecht complemented the so-called General Union of 1576, established by the Pacification of Ghent, which is why it is also referred to as the Further Union.
1656 Blaise_Pascal

Blaise Pascal publishes the first of his Lettres provinciales.

Blaise Pascal was a French mathematician, physicist, inventor, philosopher, and Catholic writer.
1719

The Principality of Liechtenstein is created within the Holy Roman Empire.

A principality is a type of monarchical state or feudal territory ruled by a prince. Examples of principalities include the Principality of Monaco, the Grand Principality of Moscow, the Principality of Sheikhan, the Principality of Catalonia, and the Principality of Wales. The Principality of Antioch is another example of a principality, yet one created during the First Crusade which included parts of Anatolia and Syria. The principality was much smaller than the County of Edessa or the Kingdom of Jerusalem.
1755 Moscow_State_University

Moscow University is established (12 January 1755 O.S.).

Moscow State University (MSU), officially M. V. Lomonosov Moscow State University, is a public research university in Moscow, Russia. The university includes 15 research institutes, 43 faculties, more than 300 departments, and six branches. Alumni of the university include past leaders of the Soviet Union and other governments. As of 2019, 13 Nobel laureates, 6 Fields Medal winners, and 1 Turing Award winner were affiliated with the university.
1789 Georgetown University

Georgetown College, the first Catholic university in the United States, is founded in Georgetown, Maryland (now a part of Washington, D.C.) when Bishop John Carroll, Rev.

Robert Molyneux, and Rev. John Ashton purchase land for the proposed academy for the education of youth.
Georgetown University is a private Jesuit research university in Washington, D.C., United States. Founded by Bishop John Carroll in 1789, it is the oldest Catholic institution of higher education in the United States, the oldest university in Washington, D.C., and the nation's first federally chartered university. The university has eleven undergraduate and graduate schools. Its main campus, located in the Georgetown historic neighborhood, is on a hill above the Potomac River and identifiable by Healy Hall, a National Historic Landmark. It is classified among "R1: Doctoral Universities – Very high research activity." The university offers degree programs in forty-eight disciplines, enrolling an average of 7,500 undergraduate and 10,000 graduate students from more than 135 countries; it is the second largest Catholic university in terms of enrollment in North America. The school's athletic teams are nicknamed the Hoyas and include a men's basketball team, which is a member of the Big East Conference. Notable alumni include 32 Rhodes Scholars, 46 Marshall Scholars, 33 Truman Scholars, 565 Fulbright Scholars, at least 12 living billionaires, 26 U.S. governors, two U.S. Supreme Court justices, two U.S. presidents, and 116 members of the United States Congress including 26 senators, as well as international royalty and more than a dozen foreign heads of state. Georgetown has educated more U.S. diplomats than any other university including at least 92 ambassadors of the United States, as well as a number of American politicians and civil servants.
1793 Second Partition of Poland

Second Partition of Poland.

The 1793 Second Partition of Poland was the second of three partitions (or partial annexations) that ended the existence of the Polish–Lithuanian Commonwealth by 1795. The second partition occurred in the aftermath of the Polish–Russian War of 1792 and the Targowica Confederation of 1792, and was approved by its territorial beneficiaries, the Russian Empire and the Kingdom of Prussia. The division was ratified by the coerced Polish parliament (Sejm) in 1793 (see the Grodno Sejm) in a short-lived attempt to prevent the inevitable complete annexation of Poland, the Third Partition.
1795 Zuiderzee

After crossing the frozen Zuiderzee, the French cavalry capture 14 Dutch ships and 850 guns, in a rare occurrence of surrender of naval vessels to land forces.

The Zuiderzee or Zuider Zee, historically called Lake Almere and Lake Flevo, was a shallow bay of the North Sea in the northwest of the Netherlands. It extended about 100 km (62 mi) inland and at most 50 km (31 mi) wide, with an overall depth of about 4 to 5 m and a coastline of about 300 km (190 mi). It covered 5,000 km2 (1,900 sq mi). Its name is Dutch for "southern sea", indicating that the name originates in Friesland, to the north of the Zuiderzee.
1846 Slavery in Tunisia

Slavery in Tunisia is abolished.

Slavery in Tunisia was a specific manifestation of the Arab slave trade, which was abolished on 23 January 1846 by Ahmed I Bey. Tunisia was in a similar position to that of Algeria, with a geographic position which linked it with the main Trans-Saharan routes. It received caravans from Fezzan and Ghadamès, which consisted solely, in the eighteenth century, of gold powder and slaves, according to contemporary witnesses. At the beginning of the nineteenth century, slaves arrived annually in numbers ranging between 500 and 1,200. From Tunisia they were carried on to the ports of the Levant.
1849 Elizabeth Blackwell

Elizabeth Blackwell is awarded her M.D.

by the Geneva Medical College of Geneva, New York, becoming the United States' first female doctor.
Elizabeth Blackwell (3 February 1821 – 31 May 1910) was an English-American physician, notable as the first woman to earn a medical degree in the United States, and the first woman on the Medical Register of the General Medical Council for the United Kingdom. Blackwell played an important role in both the United States and the United Kingdom as a social reformer, and was a pioneer in promoting education for women in medicine. Her contributions remain celebrated with the Elizabeth Blackwell Medal, awarded annually to a woman who has made a significant contribution to the promotion of women in medicine. Blackwell was not initially interested in a career in medicine. She became a schoolteacher in order to support her family. This occupation was seen as suitable for women during the 1800s; however, she soon found it unsuitable for her. Blackwell's interest in medicine was sparked after a friend fell ill and remarked that, had a female doctor cared for her, she might not have suffered so much. Blackwell began applying to medical schools and immediately began to endure the prejudice against her sex that would persist throughout her career. She was rejected from each medical school she applied to, except Geneva Medical College in New York, in which the male students voted in favor of Blackwell's acceptance, albeit as a joke. Thus, in 1847, Blackwell became the first woman to attend medical school in the United States. In 1871, Geneva Medical College was disbanded and was transferred to Syracuse University until 1950 when it became SUNY Upstate Medical University, which counts Elizabeth Blackwell among its alumni. Blackwell's inaugural thesis on typhoid fever, published in 1849 in the Buffalo Medical Journal and Monthly Review, shortly after she graduated, was the first medical article published by a female student from the United States. It portrayed a strong sense of empathy and sensitivity to human suffering, as well as strong advocacy for economic and social justice. This perspective was deemed by the medical community as feminine. Blackwell founded the New York Infirmary for Women and Children with her sister Emily Blackwell in 1857, and began giving lectures to female audiences on the importance of educating girls. She played a significant role during the American Civil War by organizing nurses, and the Infirmary developed a medical school program for women, providing substantial work with patients (clinical education). Returning to England, she helped found the London School of Medicine for Women in 1874.
1870 Montana

In Montana, U.S.

cavalrymen kill 173 Native Americans, mostly women and children, in what becomes known as the Marias Massacre.
Montana is a landlocked state in the Mountain West subregion of the Western United States. It is bordered by Idaho to the west, North Dakota to the east, South Dakota to the southeast, Wyoming to the south, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, but the eighth-least populous state and the third-least densely populated state. Its capital is Helena, while the most populous city is Billings. The western half of the state contains numerous mountain ranges, particularly the Rocky Mountains, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state.
1879 Anglo-Zulu War

Anglo-Zulu War: The Battle of Rorke's Drift ends.

The Anglo-Zulu War, or simply the Zulu War, was fought in present-day South Africa from January to early July 1879 between forces of the British Empire and the Zulu Kingdom. Two famous battles of the war were the Zulu victory at Isandlwana and the British defence at Rorke's Drift. Following the passing of the British North America Act 1867 forming a federation in Canada, Lord Carnarvon thought that a similar political effort, coupled with military campaigns, might lead to a ruling white minority over a black majority in South Africa. This would yield a large pool of cheap labour for the British sugar plantations and mines, and was intended to bring the African Kingdoms, tribal areas, and Boer republics into South Africa. In 1874, Sir Bartle Frere was appointed as British High Commissioner for Southern Africa to effect such plans. Among the obstacles were the armed independent states of the South African Republic and the Zulu Kingdom. Frere, on his own initiative, sent a provocative ultimatum on 11 December 1878 to Zulu King Cetshwayo. Upon its rejection, he ordered Lord Chelmsford to invade Zululand. The war had several particularly bloody battles, including an opening victory for the Zulu at the Battle of Isandlwana, followed by the defence of Rorke's Drift by a small British Garrison from an attack by a large Zulu force. However, the British eventually gained the upper hand at Kambula, before taking the Zulu capital of Ulundi. The British eventually won the war, ending Zulu dominance of the region. The British Empire made the Zulu Kingdom a protectorate and later annexed it in 1887. The war dispelled prior colonial notions of British invincibility, due to their massive early defeats. Together with famines, diplomatic misadventures, and other unpopular wars overseas (such as the Second Anglo-Afghan War), it contributed to the ejection of Benjamin Disraeli's government from office in 1880, after only one term.
1900 Second_Boer_War

Second Boer War: The Battle of Spion Kop between the forces of the South African Republic and the Orange Free State and British forces ends in a British defeat.

The Second Boer War was a conflict fought between 1899 and 1902 between the British Empire and the Boer republics, triggered by the discovery of gold in the Transvaal, specifically the Witwatersrand gold fields, and the ensuing political dispute over the voting rights of British expatriates (Uitlanders).
1904 Ålesund fire

Ålesund Fire: The Norwegian coastal town Ålesund is devastated by fire, leaving 10,000 people homeless and one person dead.

Kaiser Wilhelm II funds the rebuilding of the town in Jugendstil style.
The Ålesund fire happened on 23 January 1904 in the Norwegian city of Ålesund. It destroyed almost the whole city centre, built mostly of wood, like the majority of Norwegian towns at the time. The town has since been rebuilt and it is now the administrative centre of Ålesund Municipality.
1909 RMS Republic

RMS Republic, a passenger ship of the White Star Line, becomes the first ship to use the CQD distress signal after colliding with another ship, the SS Florida, off the Massachusetts coastline, an event that kills six people.

The Republic sinks the next day.
RMS Republic was a steam-powered ocean liner built in 1903 by Harland and Wolff in Belfast, and lost at sea in a collision in 1909 while sailing for the White Star Line. The ship was equipped with a new Marconi wireless telegraphy transmitter, and issued a CQD distress call, resulting in the saving of around 1,500 lives, the first major marine rescue made possible by radio. Known as the "Millionaires' Ship" because of the number of wealthy Americans who traveled by her, she was described as a "palatial liner" and was the flagship of White Star Line's Boston service.
1912 First International Opium Convention

The First International Opium Convention is signed at The Hague.

It was followed in 1925 by the Second International Opium Convention signed in Geneva.
1919 Regional Congress of Peasants, Workers and Insurgents

The First Regional Congress of Peasants, Workers and Insurgents is held by the Makhnovshchina at Velykomykhailivka.

The Regional Congresses of Peasants, Workers and Insurgents represented the "highest form of democratic authority" within the political system of the Makhnovshchina. They brought together delegates from the region's peasantry, industrial workers and insurgent soldiers, which would discuss the issues at hand and take their decisions back with them to local popular assemblies.
1920 Wilhelm_II

The Netherlands refuses to surrender the exiled Kaiser Wilhelm II of Germany to the Allies.

Wilhelm II was the last German Emperor from 1888 until his abdication in 1918. His fall from power marked the end of the German Empire as well as the Hohenzollern dynasty's 400-year rule over Prussia.
1922 Insulin_(medication)

The first successful treatment with insulin is given to 14-year-old diabetic Leonard Thompson.

As a medication, insulin is any pharmaceutical preparation of the protein hormone insulin that is used to treat high blood glucose. Such conditions include type 1 diabetes, type 2 diabetes, gestational diabetes, and complications of diabetes such as diabetic ketoacidosis and hyperosmolar hyperglycemic states. Insulin is also used along with glucose to treat hyperkalemia. Typically it is given by injection under the skin, but some forms may also be used by injection into a vein or muscle. There are various types of insulin, suitable for various time spans. The types are often all called insulin in the broad sense, although in a more precise sense, insulin is identical to the naturally occurring molecule whereas insulin analogues have slightly different molecules that allow for modified time of action. It is on the World Health Organization's List of Essential Medicines. In 2023, it was the 157th most commonly prescribed medication in the United States, with more than 3 million prescriptions.
1937

The trial of the anti-Soviet Trotskyist center sees seventeen mid-level Communists accused of sympathizing with Leon Trotsky and plotting to overthrow Joseph Stalin's regime.

The Moscow trials were a series of show trials held by the Soviet Union between 1936 and 1938 at the instigation of Joseph Stalin. They were nominally directed against "Trotskyists" and members of the "Right Opposition" of the Communist Party of the Soviet Union.The "Case of the Trotskyite–Zinovievite Terrorist Center" ; The "Case of the Anti-Soviet Trotskyist Center" ; and The "Case of the Anti-Soviet 'Bloc of Rightists and Trotskyites'".
1941 Charles_Lindbergh

Charles Lindbergh testifies before the U.S.

Congress and recommends that the United States negotiate a neutrality pact with Adolf Hitler.
Charles Augustus Lindbergh was an American aviator, military officer, and author. On May 20–21, 1927, he made the first nonstop flight from New York to Paris, a distance of 3,600 miles (5,800 km), flying alone for over 33 hours. His aircraft, the Spirit of St. Louis, was built to compete for the $25,000 Orteig Prize for the first flight between the two cities. Although not the first transatlantic flight, it was the first solo crossing of the Atlantic and the longest at the time by nearly 2,000 miles (3,200 km), setting a new flight distance world record. The achievement garnered Lindbergh worldwide fame and stands as one of the most consequential flights in history, signalling a new era of international air transportation.
1942 World_War_II

World War II: The Battle of Rabaul commences Japan's invasion of Australia's Territory of New Guinea.

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.
