April 16 in History

The 1450s BC was a decade lasting from January 1, 1459, BC to December 31, 1450, BC.

AD 69 (LXIX) was a common year starting on Sunday of the Julian calendar. In the Roman Empire, it was known as the Year of the consulship of Galba and Vinius. The denomination AD 69 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

AD 73 (LXXIII) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Domitian and Messalinus. The denomination AD 73 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

The Byzantine Papacy was a period of Byzantine domination of the Roman Papacy from 537 to 752, when popes required the approval of the Byzantine Emperor for their episcopal consecration, and many popes were chosen from the apocrisiarii (liaisons from the pope to the emperor) or the inhabitants of Byzantine-ruled Greece, Syria, or Sicily. Justinian I reconquered the Italian Peninsula in the Gothic War (535–554) and appointed the next three popes, a practice that would be continued by his successors and later be delegated to the Exarchate of Ravenna. With the exception of Martin I, no pope during this period questioned the authority of the Byzantine monarch to confirm the election of the bishop of Rome before consecration could occur; however, theological conflicts were common between pope and emperor in the areas such as monothelitism and iconoclasm. Greek speakers from Greece, Syria, and Sicily replaced members of the powerful Roman nobles in the papal chair during this period. Rome under the Greek popes constituted a "melting pot" of Western and Eastern Christian traditions, reflected in art as well as liturgy.

Stefan Uroš IV Dušan (Serbian Cyrillic: Стефан Урош IV Душан), also known as Dušan the Mighty (Serbian Cyrillic: Душан Силни; c. 1308 – 20 December 1355), was the King of Serbia from 8 September 1331 and Emperor of the Serbs, Greeks, Bulgarians and Albanians from 16 April 1346 until his death in 1355. Dušan is considered one of the greatest medieval Balkan conquerors. Dušan conquered a large part of Southeast Europe, becoming one of the most powerful monarchs of the era. Under Dušan's rule, Serbia was the most powerful state in Southeast Europe and one of the most powerful European states. At the time, Serbia was an Eastern Orthodox, multi-ethnic, and multilingual empire that stretched from the Danube in the north to the Gulf of Corinth in the south, with its capital in Skopje. He enacted the constitution of the Serbian Empire, known as Dušan's Code, perhaps the most important literary work of medieval Serbia. Dušan promoted the Serbian Church from an archbishopric to a patriarchate, completed his father's mausoleum Visoki Dečani Monastery (now a UNESCO site), and founded the monastery of the Holy Archangels, among others. Under his rule, Serbia reached its territorial, political, economic, and cultural peak. Stefan Dušan worked to forge a coalition with Venice to address the advancing threat of the Ottoman Turks into Europe. However, his efforts were interrupted by his sudden death in December 1355 at his court in Prizren. After his death, the Serbian Empire began to weaken significantly. With the death of Dušan's successor, Emperor Stefan Uroš V, the empire was definitively divided into numerous independent Serbian states, marking what is historically referred to as the Fall of the Serbian Empire. He was originally buried in his foundation near Prizren, but his remains were later relocated to the Church of Saint Mark in Belgrade, where they rest to this day.

The Revolt of the Comuneros (Spanish: Guerra de las Comunidades de Castilla, "War of the Communities of Castile") was an uprising by citizens of Castile against the rule of Charles I and his administration between 1520 and 1521. At its height, the rebels controlled the heart of Castile, ruling the cities of Valladolid, Tordesillas, and Toledo. The revolt occurred in the wake of political instability in the Crown of Castile after the death of Queen Isabella I in 1504. Isabella's daughter Joanna succeeded to the throne. Due to Joanna's mental instability, Castile was ruled by the nobles and her father, King Ferdinand II of Aragon, as a regent, while Joanna was confined. After Ferdinand's death in 1516, Joanna's sixteen-year-old son Charles was proclaimed her co-monarch of both Castile and Aragon; while Joanna also succeeded as Queen of Aragon, during her co-regency with her own son, she remained confined. Charles had been raised in the Netherlands with little knowledge of Castilian. He arrived in Spain in October 1517 accompanied by a large retinue of Flemish nobles and clerics. These factors resulted in mistrust between the new king and the Castilian social elites, who could see the threat to their power and status. In 1519, Charles was elected Holy Roman Emperor. He departed for Germany in 1520, leaving the Dutch cardinal Adrian of Utrecht to rule Castile in his absence. Soon, a series of anti-government riots broke out in the cities, and local city councils (Comunidades) took power. The rebels chose Charles' own mother, Queen Joanna, as an alternative ruler, hoping they could control her madness. The rebel movement took on a radical anti-feudal dimension, supporting peasant rebellions against the landed nobility. On 23 April 1521, after nearly a year of rebellion, the reorganized supporters of the emperor struck a crippling blow to the comuneros at the Battle of Villalar. The following day, rebel leaders Juan López de Padilla, Juan Bravo, and Francisco Maldonado were beheaded. The army of the comuneros fell apart. Only the city of Toledo kept alive the rebellion led by María Pacheco, until its surrender in October 1521. The character of the revolution is a matter of historiographical debate. According to some scholars, the revolt was one of the first modern revolutions, notably because of the anti-noble sentiment against social injustice and its basis on ideals of democracy and freedom. Others consider it a more typical rebellion against high taxes and perceived foreign control. From the 19th century onwards, the revolt has been mythologized by various Spaniards, generally liberals who drew political inspiration from it. Conservative intellectuals have traditionally adopted more pro-Imperial stances toward the revolt, and have been critical of both the motives and the government of the comuneros. With the end of Franco's dictatorship and the establishment of the autonomous community of Castile and León, positive commemoration of the Comunidades has grown. 23 April is now celebrated as Castile and León Day, and the incident is often referred to in Castilian nationalism.

Conquistadors or conquistadores were Spanish and Portuguese colonists who explored, traded with, and conquered many parts of the Americas, Africa, Asia, and Oceania during the Age of Discovery. Sailing beyond the Iberian Peninsula, they established numerous colonies and trade routes, and brought much of the New World under the dominion of Spain and Portugal.

The Battle of Culloden took place on 16 April 1746, near Inverness, in the Scottish Highlands. A Jacobite army under Charles Edward Stuart was decisively defeated by a British government force commanded by the Duke of Cumberland, thereby ending the Jacobite rising of 1745. Charles landed in Scotland in July 1745, seeking to restore his father James Francis Edward Stuart to the British throne. He quickly won control of large parts of Scotland, and an invasion of England reached as far south as Derby before being forced to turn back. However by April 1746 the Jacobites were short of supplies, facing a superior and better-equipped opponent. The Jacobite commanders decided their only option was to stand and fight. When the two armies met at Culloden, the battle was brief, lasting less than an hour, with the Jacobites suffering an overwhelming and bloody defeat. This effectively ended both the 1745 rising and Jacobitism as a significant element in British politics.

Franz Friedrich Wilhelm von Fürstenberg (7 August 1729 in Schloss Herdringen – 16 September 1810 in Münster) was a German politician and the most important statesman in the Principality of Münster in the second half of the 18th century. Fürstenberg was committed to a cautious and enlightened course of reform.

The Spithead and Nore mutinies were two major mutinies by sailors of the Royal Navy in 1797. They were the first in an increasing series of outbreaks of maritime radicalism in the Atlantic World. Despite their temporal proximity, the mutinies differed in character. The Spithead mutiny was a simple, peaceful, successful strike action to address economic grievances, while the Nore mutiny was a more radical action, articulating political ideals as well, which failed. The mutinies were extremely concerning for Britain, because at the time the country was at war with Revolutionary France, and the Navy was the main component of the war effort. There were also concerns among the government that the mutinies might be part of wider attempts at revolutionary sedition instigated by societies such as the London Corresponding Society and the United Irishmen.

The French Revolutionary Wars were a series of sweeping military conflicts resulting from the French Revolution that lasted from 1792 until 1802. They pitted France against Great Britain, Austria, Prussia, Russia, and several other countries. The wars are divided into two periods: the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered territories in the Italian peninsula, the Low Countries, and the Rhineland with its very large and powerful military which had been totally mobilized for war against most of Europe with mass conscription of the vast French population. French success in these conflicts ensured military occupation and the spread of revolutionary principles over much of Europe.

The United States Senate is a chamber of the bicameral United States Congress; it is the upper house, and the U.S. House of Representatives is the lower house. Together, the Senate and House have the authority under Article One of the Constitution to make and pass or defeat federal legislation.

The French Army is the land service branch of the French Armed Forces. The Army is commanded by the Chief of Staff of the French Army (CEMAT), who is subordinate to the Chief of the Defence Staff (CEMA), who in turn is responsible to the President of France. CEMAT is also directly responsible to the Ministry of Armed Forces for administration, preparation and equipment.

Māori are the indigenous Polynesian people of mainland New Zealand. Māori are descended from East Polynesian settlers who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed a distinct culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some Polynesians moved to the Chatham Islands from the New Zealand mainland, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori.

The Great Indian Peninsula Railway was a predecessor of the Central Railway, whose headquarters was at the Bori Bunder railway station in Mumbai. The Great Indian Peninsula Railway Company was incorporated on 1 August 1849 by the Great Indian Peninsula Railway Company Act 1849 of the Parliament of the United Kingdom. It had a share capital of 50,000 pounds. On 21 August 1847 it entered into a formal contract with the East India Company for the construction and operation of a railway line, 56 km long, to form part of a trunk line connecting Bombay with Khandesh and Berar and generally with the other presidencies of India. The Court of Directors of the East India Company appointed James John Berkley as Chief Resident Engineer and Charles Buchanan Ker and Robert Wilfred Graham as his assistants. It was India's first passenger railway, the original 21 miles (33.8 km) section opening in 1853, between Bombay (Mumbai) and Tanna. On 1 July 1925, its management was taken over by the government. On 5 November 1951, it was incorporated into the Central Railway.

The American Civil War was a civil war in the United States between the Union and the Confederacy, 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 and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the abolition of slavery, freeing four million African Americans.

The Vicksburg campaign was a series of maneuvers and battles in the Western Theater of the American Civil War directed against Vicksburg, Mississippi, a fortress city that dominated the last Confederate-controlled section of the Mississippi River. The Union Army of the Tennessee under Major General Ulysses S. Grant gained control of the river by capturing this stronghold and defeating Lieutenant General John C. Pemberton's forces stationed there. The campaign consisted of many important naval operations, troop maneuvers, failed initiatives, and eleven distinct battles from December 26, 1862, to July 4, 1863. Military historians divide the campaign into two formal phases: operations against Vicksburg (December 1862 – January 1863) and Grant's operations against Vicksburg (March–July 1863). Grant initially planned a two-pronged approach in which half of his army, under Maj. Gen. William Tecumseh Sherman, would advance to the Yazoo River and attempt to reach Vicksburg from the northeast, while Grant took the remainder of the army down the Mississippi Central Railroad. Both of these initiatives failed. Grant conducted a number of "experiments" or expeditions—Grant's bayou operations—that attempted to enable waterborne access to the Mississippi south of Vicksburg's artillery batteries. All five of these initiatives failed as well. Finally, Union gunboats and troop transport boats ran the batteries at Vicksburg and met up with Grant's men who had marched overland in Louisiana. On April 29 and 30, 1863, Grant's army crossed the Mississippi and landed at Bruinsburg, Mississippi. An elaborate series of demonstrations and diversions fooled the Confederates and the landings occurred without opposition. Over the next 17 days, Grant maneuvered his army inland and won five battles, captured the state capital of Jackson, Mississippi, and assaulted and laid siege to Vicksburg. After Pemberton's army surrendered on July 4 (one day after the Confederate defeat at Gettysburg), and when Port Hudson surrendered to Maj. Gen. Nathaniel P. Banks on July 9, Texas and Arkansas were effectively cut off from the Confederacy, and the Mississippi River was once again open for northern commerce to reach the Gulf of Mexico, and as a supply line for the Union army. Grant's Vicksburg campaign is studied as a masterpiece of military operations and a major turning point of the war.

The Senate of Finland combined the functions of cabinet and supreme court in the Grand Duchy of Finland and, from 1917, in independent Finland. It was established in 1809 as the Governing Council of the Grand Duchy of Finland, renamed the Imperial Senate of Finland in 1816, and dissolved in 1918.

Dodge City is a city in and the county seat of Ford County, Kansas, United States. As of the 2020 census, the population of the city was 27,788. It was named after nearby Fort Dodge, which was named in honor of Grenville Dodge. The city is known in American culture for its history as a wild frontier town of the Old West.

Natural Bridges National Monument is a U.S. National Monument located about 50 miles (80 km) northwest of the Four Corners boundary of southeast Utah, in the western United States, at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name. The three bridges in the park are named Kachina, Owachomo, and Sipapu (the largest), which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. During periods of flash floods, particularly, the stream undercuts the walls of rock that separate the meanders (or "goosenecks") of the stream until the rock wall within the meander is undercut and the meander is cut off and the new stream bed then flows underneath the bridge. Eventually, as erosion and gravity enlarge the bridge's opening, the bridge collapses under its own weight. There is evidence of at least two collapsed natural bridges within the Monument.

Ice hockey, known simply as hockey in North America and parts of Europe, is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. The two opposing teams score by using their sticks to control and advance a vulcanized rubber hockey puck, and then shooting it into the net of the other team. Each goal is worth one point. The team with the highest score after an hour of gameplay, broken down into three 20-minute periods, is declared the winner; ties are broken in overtime or a shootout. In a formal game, each team has six skaters on the ice at a time, barring any penalties, including a goaltender. It is a full contact game and one of the more physically demanding team sports.

Harriet Quimby (May 11, 1875 – July 1, 1912) was an American pioneering aviator, journalist, and film screenwriter. In 1911, she became the first woman in the United States to receive a pilot's license and in 1912 the first woman to fly solo across the English Channel. Although Quimby flew for only one year and died at the age of 37 in a flying accident, she strongly influenced the role of women in aviation.

The Russian Revolution was a period of political and social change in Russia, starting in 1917. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a civil war. It can be seen as the precursor for other revolutions that occurred in the aftermath of World War I, such as the German Revolution of 1918–1919. The Russian Revolution was a key event of the 20th century. The Russian Revolution was inaugurated with the February Revolution in 1917, in the midst of World War I. With the German Empire inflicting defeats on the front, and increasing logistical problems causing shortages of bread and grain, the Russian Army was losing morale, with large scale mutiny looming. Officials were convinced that if Tsar Nicholas II abdicated, the unrest would subside. Nicholas stepped down on 15 March [O.S. 2 March], ushering in a provisional government led by the Duma (parliament). During the unrest, Soviet councils were formed by locals in Petrograd (now Saint Petersburg) that initially did not oppose the new government; however, the Soviets insisted on their influence in the government and control over militias. By March, Russia had two rival governments. The Provisional Government held state power in military and international affairs, whereas the network of Soviets held domestic power. Critically, the Soviets held the allegiance of the working class, and urban middle class. There were mutinies, protests and strikes. Socialist and other leftist political organizations competed for influence within the Provisional Government and Soviets. Factions included the Mensheviks, Socialist Revolutionaries, Anarchists, and the Bolsheviks, a far-left party led by Vladimir Lenin. The Bolsheviks won popularity with their program promising peace, land, and bread: an end to the war, land for the peasantry, and ending famine. After assuming power, the Provisional Government continued fighting the war in spite of public opposition. Taking advantage, the Bolsheviks and other factions gained popular support to advance the revolution. Responding to discontent in Petrograd, the Provisional Government repressed protestors leading to the July Days. The Bolsheviks merged workers' militias loyal to them into the Red Guards. The volatile situation reached its climax with the October Revolution, a Bolshevik armed insurrection in Petrograd beginning 7 November [O.S. 25 October] that overthrew the Provisional Government. The Bolsheviks established their own government and proclaimed the establishment of the Russian Soviet Federative Socialist Republic (RSFSR). Under pressure from German military offensives, the Bolsheviks relocated the capital to Moscow. The RSFSR began reorganizing the empire into the world's first socialist state, to practice soviet democracy on a national and international scale. Their promise to end Russia's participation in World War I was fulfilled when Bolshevik leaders signed the Treaty of Brest-Litovsk with Germany in March 1918. The Bolsheviks established the Cheka, a secret police and revolutionary security service working to uncover, punish, and eliminate those considered to be "enemies of the people" in campaigns called the Red Terror. Although the Bolsheviks held large support in urban areas, they had foreign and domestic enemies that refused to recognize their government. Russia erupted into a bloody civil war, which pitted the Reds (Bolsheviks), against their enemies, which included nationalist movements, anti-Bolshevik socialist parties, anarchists, monarchists and liberals; the latter two parties strongly supported the Russian White movement which was led mainly by right-leaning officers and seen as fighting for the restoration of the imperial order. The Bolshevik commissar Leon Trotsky began organizing workers' militias loyal to the Bolsheviks into the Red Army. While key events occurred in Moscow and Petrograd, every city in the empire was convulsed, including the provinces of national minorities, and in the rural areas peasants took over and redistributed land. As the war progressed, the RSFSR established Soviet power in Armenia, Azerbaijan, Byelorussia, Georgia, and Ukraine. Wartime cohesion and intervention from foreign powers prompted the RSFSR to begin unifying these nations under one flag and created the Soviet Union. Historians consider the end of the revolutionary period to be in 1922, when the civil war concluded with the defeat of the White Army and separatist factions, leading to mass emigration from Russia. The victorious Bolshevik Party reconstituted itself into the All-Union Communist Party (Bolsheviks) and remained in power for six decades.

Mohandas Karamchand Gandhi (2 October 1869 – 30 January 1948) was an Indian lawyer, anti-colonial nationalist, and political ethicist who employed nonviolent resistance to lead the successful campaign for India's independence from British rule, which would later inspire movements for civil rights and freedom across the world. The honorific Mahātmā (Sanskrit: "great-souled", "venerable"), first applied to him in 1914 in South Africa, is now used throughout the world. Born and raised in a Hindu family in coastal Gujarat, Gandhi was trained in the law at the Inner Temple in London and was called to the bar at the age of 22. After two uncertain years in India, where he was unable to start a successful law practice, Gandhi moved to South Africa in 1893 to represent an Indian merchant in a lawsuit. He went on to live in South Africa for the next 21 years. Here, Gandhi raised a family and first employed nonviolent resistance in a campaign for civil rights. In 1915, aged 45, he returned to India and soon set about organising peasants, farmers, and urban labourers to protest against discrimination and excessive land tax. Assuming leadership of the Indian National Congress in 1921, Gandhi led nationwide campaigns for easing poverty, expanding women's rights, building religious and ethnic amity, ending untouchability, and, above all, achieving swaraj or self-rule. Gandhi adopted the short dhoti woven with hand-spun yarn as a mark of identification with India's rural poor. He began to live in a self-sufficient residential community, to eat simple food, and undertake long fasts as a means of both introspection and political protest. Bringing anti-colonial nationalism to the common Indians, Gandhi led them in challenging the British-imposed salt tax with the 400 km (250 mi) Dandi Salt March in 1930 and in calling for the British to quit India in 1942. He was imprisoned many times and for many years in both South Africa and India. Gandhi's vision of an independent India based on religious pluralism was challenged in the early 1940s by a Muslim nationalism which demanded a separate homeland for Muslims within British India. In August 1947, Britain granted independence, but the British Indian Empire was partitioned into two dominions, a Hindu-majority India and a Muslim-majority Pakistan. As many displaced Hindus, Muslims, and Sikhs made their way to their new lands, religious violence broke out, especially in Punjab and Bengal. Abstaining from the official celebration of independence, Gandhi visited the affected areas, attempting to alleviate distress. In the months following, he undertook several hunger strikes to stop the religious violence. The last of these was begun in Delhi on 12 January 1948, when Gandhi was 78. The belief that Gandhi had been too resolute in his defence of both Pakistan and Indian Muslims spread among some Hindus in India. Among these was Nathuram Godse, a militant Hindu nationalist from Pune, western India, who assassinated Gandhi by firing three bullets into his chest at an interfaith prayer meeting in Delhi on 30 January 1948. Gandhi's birthday, 2 October, is commemorated in India as Gandhi Jayanti, a national holiday, and worldwide as the International Day of Nonviolence. Gandhi is considered to be the Father of the Nation in post-colonial India. During India's nationalist movement and in several decades immediately after, he was also commonly called Bapu, an endearment roughly meaning "father".

The Polish–Lithuanian War was an undeclared war fought in the aftermath of World War I between newly independent Lithuania and Poland, with fighting mainly in the Vilnius and Suwałki regions, which was part of the Lithuanian Wars of Independence and lasted from May 1919 to 29 November 1920. From the spring of 1920 onward, the conflict happened alongside the wider Polish–Soviet War and was affected by its progress. It was subject to unsuccessful international mediation at the Conference of Ambassadors and the League of Nations. After World War I, the military and political situation in the region was chaotic, as multiple countries, notably Lithuania, Poland, and Soviet Russia, vied with each other over control of overlapping areas. The Polish–Lithuanian conflict was centered on Vilnius, which the Council of Lithuania declared the capital of the restored Lithuanian state. Control of Vilnius was transferred from Germans to Poles on January 2, 1919, but the Polish paramilitary lost the city to the Bolsheviks on January 5. The Polish Army seized Vilnius again on April 19, 1919 and came in contact with the Lithuanian Army fighting in the Lithuanian–Soviet War. Despite the antagonism over Vilnius, the Lithuanian and Polish armies sometimes cooperated when fighting against a common enemy, the Bolsheviks. As Lithuanian–Polish relations worsened, the Entente drew two demarcation lines in hopes to stall further hostilities. The lines did not please either side and were ignored. The first clashes between Polish and Lithuanian soldiers occurred on April 26 and May 8, 1919, near Vievis. With the Polish coup against the Lithuanian government failing in August 1919, the front stabilized until the summer of 1920. In July 1920, Polish forces retreated due to reverses in the Polish–Soviet War and the Lithuanians followed the retreating troops to secure their lands as delineated in the Soviet–Lithuanian Peace Treaty. However, the Red Army was the first to enter Vilnius. In August 1920, Poland won the Battle of Warsaw and forced the Soviets to retreat. The Polish Army encountered Lithuanian opposition, defending their new borders, which the Polish government considered illegitimate. Thus, the Polish invaded Lithuanian-controlled territory during the Battle of Sejny. Pressured by the League of Nations, Poland signed the Suwałki Agreement on October 7, 1920. The agreement left the Suwałki region on the Polish side and drew a new incomplete demarcation line, which left Vilnius vulnerable to a flanking maneuver. On October 8, 1920, Polish general Lucjan Żeligowski staged a mutiny, secretly planned and authorized by the Polish chief of state Józef Piłsudski. Żeligowski's forces marched on Vilnius and captured it one day before the Suwałki Agreement was to formally come into effect. Żeligowski proclaimed the creation of the Republic of Central Lithuania with its capital in Vilnius. Their further offensive towards Kaunas, the temporary capital of Lithuania, was halted by the Lithuanians, who thus defended their independence. On November 29, 1920, a ceasefire was signed. Overall, from early 1919 to late 1920, Vilnius would switch rule as many as seven times between Lithuanians, Poles and the Bolsheviks. The Republic of Central Lithuania was incorporated into Poland as the Wilno Voivodeship in 1922. The prolonged mediation by the League of Nations did not change the situation and the status quo was accepted in 1923. In March 1923, the Conference of Ambassadors recognized the armistice line as a de jure Polish–Lithuanian border, awarding Vilnius to Poland. However, the International Court of Justice in The Hague arbitrated in 1931 that Poland broke international law by occupying Vilnius. Lithuania remained adamant regarding its claim to Vilnius as its constitutional capital throughout the whole interwar, and breaking all diplomatic relations with Poland due to the latter's control of the city. Diplomatic relations were only restored as a result of the March 1938 Polish ultimatum to Lithuania. Vilnius was regained by Lithuania on 28 October 1939, following the Soviet–Lithuanian Mutual Assistance Treaty, twenty years after losing its capital. However, Lithuania as a whole lost its independence less than a year later following the Soviet ultimatum and occupation of the Baltic states.

The Treaty of Rapallo was an agreement signed on 16 April 1922 between Germany and Russia under which both renounced all territorial and financial claims against each other and opened friendly diplomatic relations. The treaty was negotiated by Russian foreign minister Georgi Chicherin and German foreign minister Walther Rathenau. It was a major victory for Russia especially and also Germany, and a major disappointment to France and the United Kingdom. The term "spirit of Rapallo" was used for an improvement in friendly relations between Germany and Russia. The treaty was signed in Rapallo, Italy. Ratifications were exchanged in Berlin on 31 January 1923, and registered in League of Nations Treaty Series on 19 September 1923. The treaty did not include any military provisions, but secret military co-operation was already scheduled between Germany and Russia, which was a violation of the Treaty of Versailles. A supplementary agreement, signed in Berlin on 5 November, extended the treaty to cover Germany's relations with the other Soviet republics: Armenia, Azerbaijan, Byelorussia, Georgia, and Ukraine. Ratifications were exchanged in Berlin on 26 October 1923, and the supplementary protocol was registered in League of Nations Treaty Series on 18 July 1924. The agreement was reaffirmed by the Treaty of Berlin in 1926.

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 Ustaše was a Croatian fascist and ultranationalist organization active, as one organization, between 1929 and 1945. It was formally known as the Ustaša – Croatian Revolutionary Movement. From its inception and before the Second World War, the organization engaged in a series of terrorist activities against the Kingdom of Yugoslavia. It collaborated with IMRO to assassinate King Alexander I of Yugoslavia in 1934. During World War II in Yugoslavia, the Ustaše went on to perpetrate the Holocaust and genocide against its Jewish, Serb and Roma populations, killing hundreds of thousands of Serbs, Jews, Roma, as well as Muslim and Croat political dissidents. The ideology of the movement combined aspects of Clerical fascism and Croatian ultranationalism.

Albert Hofmann was a Swiss chemist known for being the first to synthesize, ingest, and learn of the psychedelic effects of lysergic acid diethylamide (LSD). Hofmann's team also isolated, named and synthesized the principal psychedelic mushroom compounds psilocybin and psilocin. Hofmann discovered the structure of chitin in 1929. He authored more than 100 scientific articles and numerous books, including LSD: Mein Sorgenkind.

The Allied bombing of Yugoslavia in World War II involved air attacks on cities and towns in the Kingdom of Yugoslavia by the United States Army Air Force (USAAF) and Royal Air Force (RAF), including the Balkan Air Force (BAF), between 1941 and 1945, during which period the entire country was occupied by the Axis powers. Dozens of Yugoslav cities and towns were bombed, many repeatedly. These attacks included intensive air support for Yugoslav Partisan operations in May–June 1944, and a bombing campaign against transport infrastructure in September 1944 as the German Wehrmacht withdrew from Greece and Yugoslavia. This latter operation was known as Operation Ratweek. Some of the attacks caused significant civilian casualties.

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 United States Army is the land service branch of the United States Armed Forces. It is designated as the army of the United States in the United States Constitution. As a part of the United States Department of Defense, it is one of the six armed forces of the United States and one of the eight uniformed services of the United States. Founded in 1784, it succeeded the Continental Army, formed in 1775 during the American Revolutionary War.

MV Goya was a Norwegian freighter used as a troop transport by Germany and sunk with a massive loss of life near the end of World War II. Completed in 1940 for the Johan Ludwig Mowinckel Rederi company, the ship was named after Spanish artist Francisco Goya.
