March 18 in History

The 30s decade ran from January 1, AD 30, to December 31, AD 39.

Pope Zosimus was the bishop of Rome from 18 March 417 to his death on 26 December 418. Zosimus took a decided part in the protracted dispute in Gaul as to the jurisdiction of the See of Arles over that of Vienne, giving energetic decisions in favour of the former, but without settling the controversy. His fractious temper coloured all the controversies in which he took part, in Gaul, Africa and Italy, including Rome, where at his death the clergy were very much divided.

Frederick II (Italian: Federico, Sicilian: Fidiricu, German: Friedrich, Latin: Fridericus; 26 December 1194 – 13 December 1250) was King of Sicily from 1198, King of Germany from 1212, King of Italy and Holy Roman Emperor from 1220, and King of Jerusalem from 1225 to 1228. He was the son of Emperor Henry VI, of the Hohenstaufen dynasty (the second son of Emperor Frederick Barbarossa), and Queen Constance I of Sicily, of the Hauteville dynasty. Frederick is considered to be one of the most brilliant and powerful figures of the Middle Ages and ruled a vast area, extending from Sicily in the south, through much of Italy, to Germany in the north. Viewing himself as a direct successor to the Roman emperors of antiquity, he was Emperor of the Romans from his papal coronation in 1220 until his death and also a claimant to the title of King of the Romans from 1212 and unopposed holder of that dignity from 1215. As such, he was King of Germany, Italy, and Burgundy. At the age of three, he was crowned King of Sicily as co-ruler with his mother, Constance, Queen of Sicily, the daughter of Roger II of Sicily. His other royal title was King of Jerusalem by virtue of marriage and his connection with the Sixth Crusade. Frequently at war with the papacy, which was hemmed in between Frederick's lands in northern Italy and his Kingdom of Sicily (the Regno) to the south, he was "excommunicated four times between 1227 and his own death in 1250" and was often vilified in pro-papal chronicles of the time and after. Pope Innocent IV went so far as to declare him preambulus Antichristi (forerunner of the Antichrist). For his many-sided activities, dynamic personality and talents, Frederick II has been called the greatest of all the German emperors, perhaps even of all medieval rulers. In the Kingdom of Sicily and much of Italy, Frederick built upon the work of his Norman predecessors and forged an early absolutist state bound together by an efficient secular bureaucracy. He was known by the appellation Stupor mundi ('Wonder of the World') and maintains a reputation as a Renaissance man avant la lettre and polymath: a visionary statesman, an inspired naturalist, scholar, mathematician, architect, poet and composer. Frederick also reportedly spoke six languages: Latin, Sicilian, Middle High German, Old French, Greek, and Arabic. As an avid patron of science and the arts, he played a major role in promoting literature through the Sicilian School of poetry. His Sicilian imperial-royal court in Palermo, beginning around 1220, was the cultural and intellectual hub of the early 13th century and saw the first use of a literary form of an Italo-Romance language, Sicilian. The poetry that emanated from the school had a significant influence on literature and on what was to become the modern Italian language. He was also the first monarch to formally outlaw trial by ordeal, which had come to be viewed as superstitious. Though Frederick's line was still in a strong position at the time of his death, it did not survive for long, and the House of Hohenstaufen came to an end. Furthermore, the Holy Roman Empire entered a long period of decline during the Great Interregnum. His complex political and cultural legacy has continued to attract fierce debate and fascination to this day.

The Mongol invasion of Poland from late 1240 to 1241 culminated in the Battle of Legnica, where the Mongols defeated an alliance which included forces from fragmented Poland and their allies, led by Henry II the Pious, the Duke of Silesia and High Duke of Poland. The first invasion's intention was to secure the flank of the main Mongolian army attacking the Kingdom of Hungary. The Mongols neutralized any potential help to King Béla IV being provided by the Poles or any military orders.

Jacques de Molay (French: [də mɔlɛ]; c. 1240–1250 – 11 or 18 March 1314), also spelled "Molai", was the 23rd and last grand master of the Knights Templar, leading the order sometime before 20 April 1292 until it was dissolved by order of Pope Clement V in 1312. Though little is known of his actual life and deeds except for his last years as Grand Master, he is one of the best known Templars. Jacques de Molay's goal as grand master was to reform the order, and adjust it to the situation in the Holy Land during the waning days of the Crusades. As European support for the Crusades diminished, the French monarchy sought to disband the order and claim the wealth of the Templars as its own. King Philip IV of France, deeply in debt to the Templars, had Molay and many other French Templars arrested in 1307 and tortured into making false confessions. When Molay later retracted his confession, Philip had him burned upon a scaffold on an island in the River Seine in March, 1314. Both the sudden end of the centuries-old order of Templars and the dramatic execution of its last leader turned Molay into a legendary figure.

Albert II (German: Albrecht II., 10 August 1397 – 27 October 1439) was King of the Romans and a member of the House of Habsburg. By inheritance he became Albert V, Duke of Austria. Through his wife Elizabeth of Luxembourg (jure uxoris), he also became King of Hungary, King of Croatia, King of Bohemia, and inherited a claim to the Duchy of Luxembourg. He played a significant role in the Hussite Wars, assisting his father-in-law Sigismund and suffering defeats like the Battle of Domažlice in 1431. Crowned King of Hungary in 1438, he struggled to control Bohemia and fought against Polish-Bohemian forces. He later became King of the Romans but died in 1439 while defending Hungary from the Ottomans. His reign saw anti-Hussite and anti-Jewish persecutions, continuing medieval crusades against perceived heretics. Austrian Jews faced increased taxation and expulsions, culminating in the 1420 Vienna pogrom, partly driven by accusations of aiding the Hussites.

Valletta, also known as Città Umilissima, is the capital city of Malta and one of its 68 council areas. Located between the Grand Harbour to the east and Marsamxett Harbour to the west, its population as of 2021 was 5,157. As Malta's capital city, it is a commercial centre for shopping, bars, dining, and café life. It is also the southernmost capital of Europe, and, at just 0.61 square kilometres (0.24 sq mi), it is the European Union's smallest capital city.

Susenyos I (Ge'ez: ሱስንዮስ Sūsinyōs; c. 1571–1575 – 17 September 1632), also known as Susenyos the Catholic, was Emperor of Ethiopia from 1607 to 1632, and a member of the Solomonic dynasty. His throne names were Seltan Sagad and Malak Sagad III. He was the son of Abeto Fasil, as well as the grandson of Abeto Yakob and the great-grandson of Dawit II. As a result, while some authorities list Susenyos as a member of the Solomonic dynasty, others consider him—rather than his son, Fasilides—as the founder of the Gondar line of the dynasty (which is, however, ultimately a subset of the Solomonic dynasty). The life of Susenyos is known through his chronicle, written by several official writers (sehafe te’ezaz). The Jesuits, who were closely associated with Susenyos’s reign, also left numerous documents on their mission in Ethiopia. Manuel de Almeida, a Portuguese Jesuit who lived in Ethiopia during Susenyos reign, described the emperor as "tall with the features of a man of quality, large handsome eyes, and an ample and well groomed beard. He wore a tunic of crimson velvet down to the knee, breeches of the Moorish style, a sash or girdle of many large pieces of fine gold, and an outer coat of damask of the same colour, like a capelhar." The Spanish Jesuit, Pedro Paez described him as "tall and well-proportioned, with large eyes, a straight nose and thin lips, a joyful expression and dark complexion. He is very good-natured and has excellent qualities; he is very prudent, a great and courageous captain, cunning and experienced in matters of war, because he has spent most of his life in it, and he has made it his office to govern an army. He is very generous, affable and a man who has the word of a king, because no fault can ever be found in what he says or promises, which is something rare in Ethiopia."

The Anglo–Powhatan Wars were three wars fought between settlers of the Colony of Virginia and the Powhatan Confederacy of Tsenacommacah in the early 17th century. The first war started in 1609 and ended in a peace settlement in 1614. The second war lasted from 1622 to 1632. The third war lasted from 1644 until 1646 and ended when Opechancanough was captured and killed. That war resulted in a defined boundary between the Native Americans and colonial lands that could only be crossed for official business with a special pass. This situation lasted until 1677 and the Treaty of Middle Plantation which established Indian reservations following Bacon's Rebellion.

John Berkeley, 1st Baron Berkeley of Stratton (1602 – 26 August 1678) of Berkeley House in Westminster and of Twickenham Park in Middlesex, was an English royalist soldier, politician and diplomat, of the Bruton branch of the Berkeley family. From 1648 he was closely associated with James, Duke of York (the future King James II), and rose to prominence, fortune, and fame. He and Sir George Carteret were the founders of the Province of New Jersey, a British colony in North America that would eventually become the U.S. state of New Jersey. The territorial designation of his title refers to his role at the Battle of Stratton, Cornwall, in 1643 at which the Royalists destroyed Parliament's field army in Devon and Cornwall.

George Clarke (1676 – 12 January 1760) was a British colonial administrator and landowner who served as the acting governor of New York from 1736 to 1743.

The American Revolution (1765–1789) was a political movement in the Thirteen Colonies of Great Britain. It began as a colonial rebellion and turned into a revolution eventually resulting into the creation of the United States, which was the outcome of the associated American Revolutionary War (1775–1783). The Second Continental Congress, as the provisional government, established the Continental Army and appointed George Washington as its commander-in-chief in 1775. The following year, the Congress passed the Lee Resolution on July 2nd and unanimously adopted the Declaration of Independence on July 4th. Throughout most of the war, the outcome appeared uncertain, but a 1781 victory by Washington and the Continental Army in the Siege of Yorktown led King George III and the Fox–North coalition in government to negotiate the cessation of British colonial rule and the acknowledgment of American sovereignty, which was formalized in the Treaty of Paris, signed on September 3, 1783. The second U.S. Constitution took effect in 1789 and the Bill of Rights was ratified in 1791.

The Low Countries theatre of the War of the First Coalition, also known as the Flanders campaign, was a series of campaigns in the Low Countries conducted from 20 April 1792 to 7 June 1795 during the first years of the War of the First Coalition. As the French Revolution radicalised, the revolutionary National Convention and its predecessors broke the Catholic Church's power (1790), abolished the monarchy (1792) and even executed the deposed king Louis XVI (1793), vying to spread the Revolution beyond the new French Republic's borders, by violent means if necessary. The First Coalition, an alliance of reactionary states representing the Ancien Régime in Central and Western Europe – Habsburg Austria, Prussia, Great Britain, the Dutch Republic, Hanover and Hesse-Kassel – mobilised military forces along all the French frontiers, threatening to invade Revolutionary France and violently restore the monarchy. The subsequent combat operations along the French borders with the Low Countries and Germany became the primary theatre of the War of the First Coalition until March 1796, when Napoleon took over French command on the Italian front.

The Tolpuddle Martyrs were six agricultural labourers from the village of Tolpuddle in Dorset, England, who were arrested and tried in 1834 for swearing a secret oath as members of a friendly society. Led by George Loveless, the group had formed the Friendly Society of Agricultural Labourers during a labour dispute over wage cuts that reduced their income to near-starvation levels. Such unions were technically legal, but the British government, wary of organised labour, invoked an obscure 1797 law against "unlawful oaths" to bring charges. In R v Loveless and Others the men were convicted and sentenced to penal transportation in Australia. They were pardoned in 1836 after mass protests by sympathisers and support from Lord John Russell, and returned to England between 1837 and 1839. Most of the men later emigrated to Canada. The Tolpuddle Martyrs became a popular cause for the early union and workers' rights movements. Annual events in Tolpuddle honour their legacy.

William Henry Fry (August 10, 1813 – December 21, 1864) was an American composer, music critic, and journalist. Fry was the first known person born in the United States to write for a large symphony orchestra, and the first to compose a publicly performed opera. He was also the first music critic for a major American newspaper, and he was the first known person to insist that his fellow countrymen support American-made music.

The revolutions of 1848, also known as the springtime of the peoples, were a series of revolutions throughout Europe that spanned almost two years, between January 1848 and October 1849. They remain the most widespread revolutionary wave in European history to date. The revolutions varied widely in their aims but generally opposed conservative systems, such as absolute monarchy and feudalism, and sought to establish nation states, founded on constitutionalism and popular sovereignty. The revolutionary wave began with the revolution in Sicily in January and spread across Europe after the revolution in France in February 1848. Over fifty countries were affected, but with no significant coordination or cooperation among their respective revolutionaries. Some of the major political contributing factors were widespread dissatisfaction with political leadership, demands for more participation in government and democracy, for freedom of the press, and by the working class for economic rights, and the rise of nationalism. Other economic factors, such as the European potato failure, triggered mass starvation, migration, and civil unrest. The uprisings were led by temporary coalitions of workers and reformers, including figures from the middle and upper classes (the bourgeoisie); however, these coalitions did not hold together for long. Many of the revolutions were quickly suppressed, as tens of thousands of people were killed, and even more were forced into exile. Despite this, significant lasting reforms included the abolition of serfdom in Austria and Hungary, the end of absolute monarchy in Denmark, and the introduction of representative democracy in the Netherlands. The revolutions were most prominent in France, Italy, the Austrian Empire, and the states of the German Confederation that would make up the German Empire in the late 19th and early 20th centuries. The wave of uprisings ended in October 1849.

Spain, officially the Kingdom of Spain, is a country in Southern and Western Europe with territories in North Africa. Featuring the southernmost point of continental Europe, it is the largest country in Southern Europe and the fourth-most populous European Union (EU) member state. Spanning the majority of the Iberian Peninsula, its territory also includes the Canary Islands, in the Eastern Atlantic Ocean; the Balearic Islands, in the Western Mediterranean Sea; and the autonomous cities of Ceuta and Melilla, in mainland Africa. Peninsular Spain is bordered to the north by France, Andorra, and the Bay of Biscay; to the east and south by the Mediterranean Sea, Gibraltar and Morocco ; and to the west by Portugal and the Atlantic Ocean. Spain's capital and largest city is Madrid; other major urban areas include Barcelona, Valencia, Seville, Málaga, Zaragoza, Bilbao, Murcia, Palma de Mallorca and Las Palmas.

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 Southern 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 president in 1860 and the growing abolitionist movement in the North. The war ended with a Union victory, 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. The Confederate States seized United States forts and other federal assets in the South. The war began on April 12, 1861, when the Confederate States 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 Confederate 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. Union 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 Union blockade of Confederate ports, the Union army marshaled resources and the manpower to attack the Confederate States army from all directions. That 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 (except as punishment for a crime) and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild the country, reunite by bringing the former Confederate states back into the United States, and grant civil rights to freed black slaves. The war is one of the most extensively studied and written about episodes in the history of the United States, and it remains the subject of cultural and historiographical debate. Interest continues in 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 U.S. history. The technology and brutality of the Civil War foreshadowed the coming world wars.

The Paris Commune (French: Commune de Paris, pronounced [kɔ.myn də pa.ʁi]) was a French revolutionary government that seized power in Paris on 18 March 1871 and controlled parts of the city until 28 May 1871. During the Franco-Prussian War of 1870–1871, the French National Guard had defended Paris, and working class radicalism grew among its soldiers. Following the establishment of the French Third Republic in September 1870 (under French chief-executive Adolphe Thiers from February 1871) and the complete defeat of the French Army by the Germans by March 1871, soldiers of the National Guard seized control of the city on 18 March. The Communards killed two French Army generals and refused to accept the authority of the Third Republic; instead, the radicals set about establishing their own independent government. The Commune governed Paris for two months, promoting policies that tended toward a progressive, anti-religious system, which was an eclectic mix of many 19th-century schools of thought. These policies included the separation of church and state, self-policing, the remission of rent, the abolition of child labor, and the right of employees to take over an enterprise deserted by its owner. The Commune closed all Catholic churches and schools in Paris. Feminism, communism, old-style social democracy (a mix of reformism and revolutionism) and anarchist/Proudhonist currents, among other socialist schools of thought, played important roles in the Commune. The various Communards had little more than two months to achieve their respective goals before the national French Army suppressed the Commune during the semaine sanglante ("bloody week") beginning on 21 May 1871. The national forces still loyal to the Third Republic government either killed in battle or executed an estimated 10,000 to 15,000 Communards, though one unconfirmed estimate from 1876 put the toll as high as 20,000. In its final days the Commune executed the Archbishop of Paris, Georges Darboy, and about one hundred hostages, mostly gendarmes and priests. National army forces took 43,522 Communards as prisoners, including 1,054 women. More than half of the prisoners had not fought, and were released immediately. The Third Republic tried around 15,000 in court, 13,500 of whom were found guilty; 95 were sentenced to death, 251 to forced labor, and 1,169 to deportation (mostly to New Caledonia). Many other Commune supporters, including several of the leaders, fled abroad, mostly to England, Belgium or Switzerland. All the surviving prisoners and exiles received pardons in 1880 and could return home, where some resumed political careers. Debates over the policies and result of the Commune had significant influence on the ideas of Karl Marx and Friedrich Engels, who described the régime in Paris as the first example of the dictatorship of the proletariat. Engels wrote: "Of late, the Social-Democratic philistine has once more been filled with wholesome terror at the words: Dictatorship of the Proletariat. Well and good, gentlemen, do you want to know what this dictatorship looks like? Look at the Paris Commune. That was the Dictatorship of the Proletariat."

Phoebe ( FEE-bee) is the most massive irregular satellite of Saturn with a mean diameter of 213 km (132 mi). It was discovered by William Henry Pickering on 18 March 1899 from photographic plates that had been taken by DeLisle Stewart starting on 16 August 1898 at the Boyden Station of the Carmen Alto Observatory near Arequipa, Peru. It was the first natural satellite to be discovered photographically. Phoebe was the first target encountered upon the arrival of the Cassini spacecraft in the Saturn system in 2004, and is thus unusually well-studied for an irregular moon of its size. Cassini's trajectory to Saturn and time of arrival were chosen to permit this flyby. After the encounter and its insertion into orbit, Cassini did not go much beyond the orbit of Iapetus. Phoebe has a moderately eccentric, retrograde orbit, making it part of Saturn's Norse group of satellites. It is the second-largest retrograde satellite in the Solar System after Triton. Phoebe is roughly spherical and has a differentiated interior. It was spherical and hot early in its history and was battered out of roundness by repeated impacts. There is some evidence that it may be a captured centaur that originated in the Kuiper belt.

Macario Sakay y de León (March 1, 1870 – September 13, 1907) was a Filipino general who took part in the 1896 Philippine Revolution against the Spanish Empire and in the Philippine–American War. After the war was declared over by the United States in 1902, Sakay continued resistance by leading guerrilla raids. The following year he established the Tagalog Republic with himself as president. Sakay was executed by hanging in 1907.

George I (born Prince William of Schleswig-Holstein-Sonderburg-Glücksburg; 24 December 1845 – 18 March 1913) was King of Greece from 30 March 1863 until his assassination on 18 March 1913. He was the first monarch of a Greek dynasty that ruled, with a few breaks, until the monarchy was abolished in 1973. Originally a Danish prince, George was born in Copenhagen, and seemed destined for a career in the Royal Danish Navy. He was only 17 years old when he was elected king by the Greek National Assembly, which had deposed the unpopular King Otto. His nomination was both suggested and supported by the great powers: the United Kingdom of Great Britain and Ireland, the Second French Empire and the Russian Empire. He married Grand Duchess Olga Constantinovna of Russia in 1867. Two of his sisters, Alexandra and Dagmar, married into the British and Russian royal families. Edward VII of the United Kingdom and Alexander III of Russia were his brothers-in-law, and George V of the United Kingdom, Christian X of Denmark, Haakon VII of Norway, and Nicholas II of Russia were his nephews. George's reign of almost 50 years (the longest in modern Greek history) was characterized by territorial gains as Greece established its place in pre-World War I Europe. Britain ceded the Ionian Islands peacefully in 1864, while Thessaly was annexed from the Ottoman Empire after the Russo-Turkish War (1877–1878). Greece was not always successful in its territorial ambitions; it was defeated in the Greco-Turkish War of 1897. During the First Balkan War, after Greek troops had captured much of Greek Macedonia and Epirus, George was assassinated in Thessaloniki.

World War I, or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. One of the deadliest conflicts in history, World War I caused 15 to 22 million deaths, including those resulting from war crimes and genocides. The war also contributed to the spread of the Spanish flu pandemic. The conflict saw important developments in weaponry, including machine guns, artillery, aircraft, chemical weapons, and tanks.

The Treaty of Riga was signed in Riga, Latvia, on 18 March 1921 between Poland on one side and Soviet Russia (acting also on behalf of Soviet Belarus) and Soviet Ukraine on the other, ending the Polish–Soviet War (1919–1921). The chief negotiators of the peace were Jan Dąbski for the Polish side and Adolph Joffe for the Soviet side. Under the treaty, Poland recognized Soviet Ukraine and Belarus, abrogating its 1920 Treaty of Warsaw with the Ukrainian People's Republic. The Treaty of Riga established a Polish–Soviet border about 250 kilometres (160 mi) east of the Curzon Line, incorporating large numbers of Ukrainians and Belarusians into the Second Polish Republic. Poland, which agreed to withdraw from areas further east (notably Minsk), renounced claims to the Polish–Lithuanian Commonwealth's border prior to the 1772 First Partition of Poland, recovering only those eastern regions (Kresy) lost to Russia in the 1795 Third Partition. Russia and Ukraine agreed to withdraw their claims to lands west of the demarcated border line. Poland, by recognising the Bolshevik-controlled Ukrainian and Belarusian states and simultaneously withdrawing recognition of the UPR (its only ally in the Polish–Bolshevik war), was in fact giving up on the federation programme, while Russia agreed to the whole of Galicia, as well as the territories of the former Russian Empire, inhabited largely by non-Polish people, being found within Poland's borders. The treaty also addressed matters of sovereignty, citizenship, national minorities, repatriation, and diplomatic and commercial relations. The Treaty lasted until the invasion of Poland by the Soviet Union in 1939, and their borders were redefined by an agreement in 1945.

The Kronstadt rebellion (Russian: Кронштадтское восстание, romanized: Kronshtadtskoye vosstaniye) was a 1921 insurrection of Soviet sailors, naval infantry, and civilians against the Bolshevik government in the Russian port city of Kronstadt. Located on Kotlin Island in the Gulf of Finland, Kronstadt defended the former capital city, Petrograd (now Saint Petersburg), as the base of the Baltic Fleet. For sixteen days in March 1921, rebels in Kronstadt's naval fortress rose in opposition to the Soviet government which they had helped to consolidate. Led by Stepan Petrichenko, it was the last major revolt against Bolshevik rule on Russian territory during the Russian Civil War. Disappointed in the direction of the Bolshevik government, the rebels—whom Leon Trotsky himself had praised earlier as the "adornment and pride of the revolution"—demanded a series of reforms: reduction in Bolshevik power, newly elected soviets (councils) to include socialist and anarchist groups, economic freedom for peasants and workers, dissolution of the bureaucratic governmental organs created during the civil war, and the restoration of civil rights for the working class. Trotsky signed the order to crush the rebellion which outlined a series of operational measures including a warning to the sailors to stop the rebellion in advance of a Red Army assault. However, he did not personally participate in the military operations or repressions which were organized by Felix Dzerzhinsky. Convinced of the popularity of the reforms they were fighting for (which they partially tried to implement during the revolt), the Kronstadt seamen waited in vain for the support of the population in the rest of the country and rejected aid from émigrés. Although the council of officers advocated a more offensive strategy, the rebels maintained a passive attitude as they waited for the government to take the first step in negotiations. By contrast, the authorities took an uncompromising stance, presenting an ultimatum demanding unconditional surrender on 5 March. Once this period expired, the Bolsheviks raided the island several times and suppressed the revolt on 18 March after shooting and imprisoning several thousand rebels. Supporters saw the rebels as revolutionary martyrs while the authorities saw the rebels as "agents of the Entente and counter-revolution." The Bolshevik response to the revolt caused great controversy and was responsible for the disillusionment of several supporters of the Bolshevik regime, such as Emma Goldman. While the revolt was suppressed and the rebels' political demands were not met, it served to accelerate the implementation of the New Economic Policy, which replaced war communism. According to Lenin, the crisis was the most critical the Bolsheviks had yet faced, "undoubtedly more dangerous than Denikin, Yudenich, and Kolchak combined".

The Mongolian Revolution of 1921, locally known as the People's Revolution of 1921, was a military and political event by which Mongolian revolutionaries, with the assistance of the Soviet Red Army, expelled Russian White Guards from the country, and founded the Mongolian People's Republic in 1924. Although nominally independent, the Mongolian People's Republic was a satellite state of the Soviet Union until the democratic revolution in January 1990. The revolution also ended the Chinese Beiyang government's occupation of Mongolia, which had begun in 1919.

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, and whose legacy 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".

In the midday and afternoon hours of Wednesday, March 18, 1925, the deadliest tornado in United States history and second-deadliest worldwide moved through Eastern Missouri, Southern Illinois and Southern Indiana, killing 695 people and injuring 2,027 more in what is sometimes known as the Tri-State tornado. The tornado touched down as part of a larger severe weather outbreak that hit the United States on the same day, and produced catastrophic damage across numerous villages and towns in all three states.

The Spanish Civil War was fought in Spain from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans loyal to the left-leaning Popular Front government of the Second Spanish Republic included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists, who established the military-led Spanish State and were directly aided by an intervention from Fascist Italy and participation of Nazi Germany. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or communism and fascism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975.

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.

An astronaut is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member of a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and space tourists.

Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets.

A gold standard is a monetary system in which the standard economic unit of account is defined by a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971, when the United States unilaterally terminated convertibility of the US dollar into gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.

Operation Menu was a covert United States Strategic Air Command (SAC) tactical bombing campaign conducted in eastern Cambodia from 18 March 1969 to 26 May 1970 as part of the Vietnam War. The targets of these attacks were sanctuaries and base areas of the People's Army of Vietnam and the Viet Cong (VC), which used them for resupply, training, and resting between campaigns across the border in the Republic of Vietnam. The impact of the bombing campaign on the Khmer Rouge guerrillas, the PAVN, and Cambodian civilians in the bombed areas is disputed by historians.

Lon Nol was a Cambodian-Chinese military officer, politician who served as Prime Minister of Cambodia twice, as well as serving repeatedly as defence minister and provincial governor.
