May 13 in History

Pope Agapetus I (489/490 – 22 April 536) was the bishop of Rome from 13 May 535 to his death on 22 April 536. His father, Gordianus, was a priest in Rome and he may have been related to two popes, Felix III and Gregory I. In 536, Agapetus traveled to Constantinople at the behest of King Theodahad of the Ostrogoths and unsuccessfully tried to persuade Emperor Justinian I to call off a Byzantine invasion of the Ostrogoth kingdom. While in Constantinople, Agapetus also deposed the patriarch Anthimus I and personally consecrated his successor who is Menas of Constantinople. Four of Agapetus’ letters from this period have survived: two addressed to Justinian, one to the bishops of Africa, and one to the Bishop of Carthage. Agapetus was canonized in both the Catholic and Orthodox traditions; his feast day is April 22.

Baldwin I was the first count of Edessa from 1098 to 1100 and king of Jerusalem from 1100 to his death in 1118. He was the youngest son of Count Eustace II of Boulogne and Ida of Lorraine and married a Norman noblewoman, Godehilde of Tosny. He received the County of Verdun in 1096, but he soon joined the crusader army of his brother Godfrey of Bouillon and became one of the most successful commanders of the First Crusade.

The Latin Church is the largest autonomous particular church within the Catholic Church, whose members constitute the vast majority of the 1.3 billion Catholics. The Latin Church is one of 24 sui iuris churches in full communion with the pope; the other 23 are collectively referred to as the Eastern Catholic Churches, and they have approximately 18 million members combined.

Julian of Norwich (c. 1343 – after 1416), also known as Juliana of Norwich, the Lady Julian, Dame Julian or Mother Julian, was a medieval English Catholic anchoress. Her writings, now known as Revelations of Divine Love, are the earliest surviving English-language works attributed to a woman. They are also the only surviving English-language works by an anchoress. Julian lived in the English city of Norwich in Norfolk, an important centre for commerce that also had a vibrant religious life. During her lifetime, the city suffered the devastating effects of the Black Death of 1348–1350, the Peasants' Revolt (which affected large parts of England in 1381), and the suppression of the Lollards. In 1373, aged 30 and so seriously ill she thought she was on her deathbed, Julian received a series of visions or shewings of the Passion of Christ. She recovered from her illness and wrote two versions of her experiences, the earlier one being completed soon after her recovery—a much longer version, today known as the Long Text, was written many years later. Julian lived in permanent seclusion as an anchoress in her cell attached to St Julian's Church, Norwich. Four wills are known in which sums were bequeathed to a Norwich anchoress named Julian, and an account by the celebrated mystic Margery Kempe exists which provides evidence of counsel Kempe was given by the anchoress. Details of Julian's family, education, or of her life before becoming an anchoress are not known; it is unclear whether her actual name was Julian. Preferring to write anonymously, and seeking isolation from the world, she was nevertheless influential in her lifetime. While her writings were carefully preserved, the Reformation prevented their publication in print. The Long Text was first published in 1670 by the Benedictine monk Serenus de Cressy, reissued by George Hargreaves Parker in 1843, and published in a modernised version in 1864. Julian's writings emerged from obscurity in 1901 when a manuscript in the British Museum was transcribed and published with notes by Grace Warrack; many translations have been made since. Julian is today considered to be an important Christian mystic and theologian.

Amerigo Vespucci (9 March 1454 – 22 February 1512) was an Italian explorer and navigator from the Republic of Florence after whom the Americas are named. Vespucci participated in at least two voyages of the Age of Discovery between 1497 and 1504, first on behalf of Spain (1499–1500) and then for Portugal (1501–1502). In 1503 and 1505, two booklets were published under his name containing colourful descriptions of these explorations and other voyages. Both publications were extremely popular and widely read throughout much of Europe. Historians still dispute the authorship and veracity of these accounts, but they were instrumental in raising awareness of the discoveries and enhancing the reputation of Vespucci as an explorer and navigator. Vespucci claimed to have understood in 1501 that Brazil was part of a fourth continent unknown to Europeans, which he called the "New World" (Mundus Novus). The claim inspired cartographer Martin Waldseemüller to recognize Vespucci's accomplishments in 1507 by applying the Latinized form "America" to a map showing the New World. Other cartographers followed suit, securing the tradition of marking the name "America" on maps of the newly discovered continents. It is unknown whether Vespucci was ever aware of these honours. In 1505, he was made a subject of Castile by royal decree, and he was appointed to the position of piloto mayor (master navigator) for Spain's Casa de Contratación (House of Trade) in Seville in 1508, a post which he held until his death in 1512.

Mary, Queen of Scots (8 December 1542 – 8 February 1587), also known as Mary Stuart or Mary I of Scotland, was Queen of Scotland from 14 December 1542 until her forced abdication on 24 July 1567. The only surviving legitimate child of King James V of Scotland, Mary was six days old when her father died, and she inherited the throne. During her childhood, Scotland was governed by regents, first by the heir to the throne, James Hamilton, Earl of Arran, and then by her mother, Mary of Guise. In 1548, she was betrothed to Francis, the Dauphin of France, and was sent to be brought up in France, where she would be safe from invading English forces during the Rough Wooing. Mary married Francis in 1558, becoming queen consort of France from his accession in 1559 until his death in December 1560. Widowed, Mary returned to Scotland in August 1561. The tense religious and political climate following the Scottish Reformation that Mary encountered on her return to Scotland was further agitated by prominent Scots such as John Knox, who openly questioned whether her subjects had a duty to obey her. The early years of her personal rule were marked by pragmatism, tolerance, and moderation. She issued a proclamation accepting the religious settlement in Scotland as she had found it upon her return, retained advisers such as James Stewart, Earl of Moray (her illegitimate half-brother), and William Maitland of Lethington, and governed as the Catholic monarch of a Protestant kingdom. In 1565, Mary married her half-cousin Henry Stuart, Lord Darnley; they had a son, James. Their marriage soured after Darnley orchestrated the murder of Mary's Italian secretary and close friend David Rizzio. In February 1567, Darnley's residence was destroyed by an explosion, and he was found murdered in the nearby garden. James Hepburn, 4th Earl of Bothwell, was generally believed to have orchestrated Darnley's death, but he was acquitted of the charge in April 1567 and in the following month, he married Mary. Following an uprising against the couple, Mary was imprisoned in Lochleven Castle. In July 1567, she was forced to abdicate in favour of her one-year-old son James VI. After an unsuccessful attempt to regain the throne, she fled southward seeking the protection of her first cousin once removed, Elizabeth I of England. As a great-granddaughter of Henry VII of England, Mary had once claimed Elizabeth's throne as her own and was considered the legitimate sovereign of England by many English Catholics, including participants in a rebellion known as the Rising of the North. Perceiving Mary as a threat, Elizabeth had her confined in various castles and manor houses in the interior of England. After eighteen and a half years in captivity, Mary was found guilty of plotting to assassinate Elizabeth in 1586 and was beheaded the following year at Fotheringhay Castle. Mary's life and execution established her in popular culture as a romanticised historical figure.

Miyamoto Musashi was a Japanese swordsman, strategist, artist, and writer who became renowned through stories of his unique double-bladed swordsmanship and undefeated record in his 62 duels. Musashi is considered a kensei of Japan. He was the founder of the Niten Ichi-ryū style of swordsmanship. In his final years, Musashi authored The Book of Five Rings and Dokkōdō.

Johan van Oldenbarnevelt (Dutch pronunciation: [ˈjoːɦɑɱ vɑn ɔldə(m)ˈbɑrnəvɛlt]; 14 September 1547 – 13 May 1619), Heer van Berkel en Rodenrijs (1600), Gunterstein (1611) and Bakkum (1613), was a Dutch statesman and revolutionary who played an important role in the Dutch struggle for independence from Spain. Van Oldenbarnevelt was born in Amersfoort. He studied law at the universities of Leuven, Bourges, Heidelberg, and Padua, and traveled in France and Italy before settling permanently in The Hague. He favored William the Silent in his revolt against Philip II of Spain, and fought in William's army. In his later years he was a supporter of the Arminians during the religious-political controversy which split the young Dutch Republic. He was the founder of the Dutch East India Company.

Cort Sivertsen Adeler, known in Denmark as Coort Sifvertsen Adelaer, in the Netherlands as Koert Sievertsen Adelaer and in Italy as Curzio Suffrido Adelborst, was the name of honour given to Kurt Sivertsen, a Norwegian seaman, who rendered distinguished service to the Dano-Norwegian and Dutch navies, and also to the Republic of Venice against the Turks.

The War of the Bavarian Succession (German: Bayerischer Erbfolgekrieg; 3 July 1778 – 13 May 1779) was a dispute between the Austrian Habsburg monarchy and an alliance of Saxony and Prussia over succession to the Electorate of Bavaria after the extinction of the Bavarian branch of the House of Wittelsbach. The Habsburgs sought to acquire Bavaria, and the alliance opposed them, favoring another branch of the Wittelsbachs. Both sides mobilized large armies, but the only fighting in the war was a few minor battles. However, thousands of soldiers died from disease and starvation, earning the conflict the name Kartoffelkrieg (Potato War) in Prussia and Saxony; in Habsburg Austria, it was sometimes called the Zwetschgenrummel (Plum Fuss). On 30 December 1777, Maximilian III Joseph, the last of the junior Wittelsbach line, died of smallpox, leaving no children. Charles Theodore, a scion of a senior branch of the House of Wittelsbach, held the closest claim of kinship, but he also had no legitimate children to succeed him. His cousin, Charles II August, Duke of Zweibrücken, therefore had a legitimate legal claim as Charles Theodore's heir presumptive. Across Bavaria's southern border, Emperor Joseph II coveted the Bavarian territory and had married Maximilian Joseph's sister Maria Josepha in 1765 to strengthen any claim he could extend. His agreement with the heir, Charles Theodore, to partition the territory neglected any claims of the heir presumptive, Charles August. Acquiring territory in the German-speaking states was an essential part of Joseph's policy to expand his family's influence in Central Europe. For King Frederick the Great of Prussia, Joseph's claim threatened Prussian influence in German politics, but he questioned whether he should preserve the status quo through war, diplomacy, or trade. Empress Maria Theresa, Joseph's mother and co-ruler, considered any conflict over the Bavarian electorate not worth bloodshed, and neither she nor Frederick saw any point in pursuing hostilities. Joseph would not drop his claim despite his mother's contrary insistence. Elector Frederick August III of Saxony wanted to preserve the territorial integrity of Bavaria for his brother-in-law, Charles August, and had no interest in seeing the Habsburgs acquire additional territory on his southern and western borders. Despite his dislike of Prussia, which had been Saxony's enemy in two previous wars, Charles August sought the support of Frederick, who was happy to challenge the Habsburgs. France became involved to maintain the balance of power. Finally, Empress Catherine the Great of Russia's threat to intervene on the side of Prussia with fifty thousand Russian troops forced Joseph to reconsider his position. With Catherine's assistance, he and Frederick negotiated a solution to the problem of the Bavarian succession with the Treaty of Teschen, signed on 13 May 1779. For some historians, the War of the Bavarian Succession was the last of the old-style cabinet wars of the Ancien Régime era, in which troops maneuvered while diplomats traveled between capitals to resolve their monarchs' complaints. The subsequent French Revolutionary and Napoleonic Wars differed in scope, strategy, organization, and tactics.

General Charles Cornwallis, 1st Marquess Cornwallis (31 December 1738 – 5 October 1805) was a British Army officer, Whig politician and colonial administrator. In the United States and United Kingdom, he is best known as one of the leading British general officers in the American War of Independence. His surrender in 1781 to a combined Franco-American force at the siege of Yorktown ended significant hostilities in North America. Cornwallis later served as a civil and military governor in Ireland, where he helped to bring about the Act of Union; and in India, where he helped to enact the Cornwallis Code and the Permanent Settlement. Born into an aristocratic family and educated at Eton College and the University of Cambridge, Cornwallis joined the British Army in 1757, seeing action in the Seven Years' War. Upon his father's death in 1762 he succeeded to his peerage and entered the House of Lords. From 1766 to 1805 he was colonel of the 33rd Regiment of Foot. Cornwallis next saw military action in 1776 in the American War of Independence. Active in the advance forces of many campaigns, in 1780 he inflicted a major defeat on the Continental Army at the Battle of Camden. He also commanded British forces in the March 1781 Pyrrhic victory at Guilford Court House. Cornwallis surrendered his army at Yorktown in October 1781 after an extended campaign through the Southern colonies, marked by disagreements between him and his superior, Sir Henry Clinton. Despite this defeat, Cornwallis retained the confidence of successive British governments and continued to enjoy an active career. Knighted in 1786, he was in that year appointed to be Governor-General and commander-in-chief in India. There he enacted numerous significant reforms within the East India Company and its territories, including the Cornwallis Code, part of which implemented important land taxation reforms known as the Permanent Settlement. From 1789 to 1792 he led British and Company forces in the Third Anglo-Mysore War to defeat the Mysorean ruler Tipu Sultan. Returning to Britain in 1794, Cornwallis was given the post of Master-General of the Ordnance. In 1798 he was appointed Lord Lieutenant and Commander-in-chief of Ireland, where he oversaw the response to the 1798 Irish Rebellion, including a French invasion of Ireland, and was instrumental in bringing about the Union of Great Britain and Ireland. Following his Irish service, Cornwallis was the chief British signatory to the 1802 Treaty of Amiens and was reappointed to India in 1805. He died in India not long after his arrival.

Yusuf Karamanli, Caramanli or Qaramanli or al-Qaramanli, (1766–1838) was the longest-reigning Pasha of the Karamanli dynasty of Ottoman Tripolitania. He is noted for his role in the Barbary Wars against the United States.

Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. It also includes the Galápagos Province which contains the Galápagos Islands in the Pacific, about 1,000 kilometers west of the mainland. The country's capital is Quito, and the largest city is Guayaquil.

The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the United States intervention in Mexico, (April 25, 1846 – February 2, 1848) was an invasion of Mexico by the United States. It followed the 1845 American annexation of Texas, which Mexico still considered its territory because it refused to recognize the Treaties of Velasco, signed by President Antonio López de Santa Anna after he was captured by the Texian Army during the 1836 Texas Revolution. The Republic of Texas was de facto an independent country, but most of its Anglo-American citizens who had moved from the United States to Texas after 1822 wanted to be annexed by the United States. Sectional politics over slavery in the United States had previously prevented annexation because Texas would have been admitted as a slave state, upsetting the balance of power between Northern free states and Southern slave states. In the 1844 United States presidential election, Democrat James K. Polk was elected on a platform of expanding U.S. territory to Oregon, California (also Mexican territory), and Texas by any means, with the 1845 annexation of Texas furthering that goal. However, the boundary between Texas and Mexico was disputed, with the Republic of Texas and the U.S. asserting it to be the Rio Grande and Mexico claiming it to be the more northerly Nueces River. Polk sent a diplomatic mission to Mexico in an attempt to buy the disputed territory, together with California and everything in between for $25 million (equivalent to $798 million in 2024), an offer the Mexican government refused. Polk then sent a group of 80 soldiers across the disputed territory to the Rio Grande, ignoring Mexican demands to withdraw. Mexican forces interpreted this as an attack and repelled the U.S. forces on April 25, 1846, a move that Polk used to convince the Congress of the United States to declare war. Beyond the disputed area of Texas, U.S. forces quickly occupied the regional capital of Santa Fe de Nuevo México along the upper Rio Grande. U.S. forces also moved against the province of Alta California and then turned south. The Pacific Squadron of the U.S. Navy blockaded the Pacific coast in the lower Baja California Territory. The U.S. Army, under Major General Winfield Scott, invaded the Mexican heartland via an amphibious landing at the port of Veracruz on March 9 and captured the capital, Mexico City, in September 1847. Although Mexico was defeated on the battlefield, negotiating peace was politically complex. Some Mexican factions refused to consider any recognition of its loss of territory. Although Polk formally relieved his peace envoy, Nicholas Trist, of his post as negotiator, Trist ignored the order and successfully concluded the 1848 Treaty of Guadalupe Hidalgo. It ended the war, and Mexico recognized the cession of present-day Texas, California, Nevada, and Utah as well as parts of present-day Arizona, Colorado, New Mexico, and Wyoming. The U.S. agreed to pay $15 million (equivalent to $479 million in 2024) for the physical damage of the war and assumed $3.25 million of debt already owed by the Mexican government to U.S. citizens. Mexico relinquished its claims on Texas and accepted the Rio Grande as its northern border with the United States. The victory and territorial expansion Polk had spearheaded inspired patriotism among some sections of the United States, but the war and treaty drew fierce criticism for the casualties, monetary cost, and heavy-handedness. The question of how to treat the new acquisitions intensified the debate over slavery in the United States. Some scholars see the Mexican–American War as leading to the American Civil War. Many officers who had trained at West Point gained experience in the war and later played prominent leadership roles during the Civil War. In Mexico, the war worsened domestic political turmoil and led to a loss of national prestige, as it suffered large losses of life in both its military and civilian population, had its financial foundations undermined, and lost more than half of its territory.

The Principality of Montenegro was a principality in Southeastern Europe that existed from 13 March 1852 to 28 August 1910. It was then proclaimed a kingdom by Nikola I, who then became King of Montenegro.

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

The Great Comet of 1861, formally designated as C/1861 J1 and 1861 II, is a long-period comet that was visible to the naked eye for approximately 3 months. It was categorized as a great comet—one of the eight brightest comets of the 19th century.

Pakistan Railways is the state-owned railway operator in Pakistan. Founded in 1886 as the North Western State Railway and headquartered in Lahore, it owns 7,791 kilometres of operational track, stretching from Peshawar to Karachi, offering both freight and passenger services, covering 494 operational stations across Pakistan.

Robert Smalls (April 5, 1839 – February 23, 1915) was an American politician who was born into slavery in Beaufort, South Carolina. During the American Civil War, the still enslaved Smalls commandeered a Confederate transport ship in Charleston Harbor and sailed it from the Confederate-controlled waters of the harbor to the U.S. blockade that surrounded it. He then piloted the ship to the Union-controlled enclave in the Beaufort–Port Royal–Hilton Head area, where it became a Union warship. In the process, he freed himself, his crew, and their families. His example and persuasion helped convince President Abraham Lincoln to accept black soldiers into the Union Army. After the Civil War, Smalls returned to Beaufort and became a politician, winning election as a Republican to the South Carolina Legislature and the United States House of Representatives during the Reconstruction era. He authored state legislation providing for South Carolina to have the first free and compulsory public school system in the United States. He was a founder of the Republican Party of South Carolina and the last member of that party to represent South Carolina's 5th congressional district until the election of Mick Mulvaney in 2010.

The 1909 Giro d'Italia was the 1st edition of the Giro d'Italia, organized and sponsored by the Italian major sport newspaper La Gazzetta dello Sport. The event began in Milan on 13 May with a 397 km (247 mi) first stage to Bologna, finishing back in Milan on 30 May after a final stage of 206 km (128 mi) and a total distance covered of 2,447.9 km (1,521 mi). The race was won by the Italian rider Luigi Ganna of the Atala team, with fellow Italians Carlo Galetti and Giovanni Rossignoli coming in second and third respectively. Conceived by La Gazzetta to boost its circulation at the expense of its rival Corriere della Sera, the 1909 Giro was the first stage road race. Its eight stages, although relatively few compared to modern Grand Tours, were each much longer than those raced today. The event began with a long primarily flat stage that was won by Dario Beni. He lost the lead after the next stage to the eventual winner Luigi Ganna, who in turn lost it to Carlo Galetti after the mountainous third stage. Ganna regained the lead after the fourth stage and successfully defended it all the way to the finish in Milan, winning three stages en route. Atala won the team classification.

The Royal Flying Corps (RFC) was the air arm of the British Army before and during the First World War until it merged with the Royal Naval Air Service on 1 April 1918 to form the Royal Air Force. During the early part of the war, the RFC supported the British Army by artillery co-operation and photographic reconnaissance. This work gradually led RFC pilots into aerial battles with German pilots and later in the war included the strafing of enemy infantry and emplacements, the bombing of German military airfields and later the strategic bombing of German industrial and transport facilities.

Our Lady of Fátima (Portuguese: Nossa Senhora de Fátima, pronounced [ˈnɔsɐ sɨˈɲɔɾɐ ðɨ ˈfatimɐ]; formally known as Our Lady of the Holy Rosary of Fátima) is a Catholic title of Mary, mother of Jesus, based on the Marian apparitions reported in 1917 by three shepherd children at the Cova da Iria in Fátima, Portugal. The three children were Lúcia dos Santos and her cousins Francisco and Jacinta Marto. José Alves Correia da Silva, Bishop of Leiria, declared the events worthy of belief on 13 October 1930. Pope Pius XII granted a pontifical decree of canonical coronation via the papal bull Celeberrima solemnia towards the venerated image on 25 April 1946. The designated papal legate, Cardinal Benedetto Aloisi Masella, carried out the coronation on 13 May 1946, now permanently enshrined at the Chapel of the Apparitions of Fátima. The same Roman Pontiff also raised the Sanctuary of Fátima to the status of a minor basilica by the apostolic letter Luce superna on 11 November 1954. The published memoirs of Sister Lúcia in the 1930s revealed two secrets that she claimed came from the Virgin Mary, while the third secret was to be revealed by the Catholic Church in 1960. The controversial events at Fátima, including the Miracle of the Sun, gained fame due partly to elements of the secrets, prophecy and eschatological revelations allegedly related to the Second World War and possibly more global wars in the future, particularly the Virgin's request for the Consecration of Russia to the Immaculate Heart of Mary.

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.

Operation Vulcan (22 April – 1 May 1943) was one of the last ground attacks by the Allied forces of the First Army against the Italian and German forces in Tunisia in the last Axis bridgeheads in North Africa, during the Tunisian campaign of the Second World War. An Axis attack on British positions on 20 April failed to delay Operation Vulcan which commenced two days later. The Allies hoped to breach the Axis defences and break out beyond towards Bizerte and Tunis. The attack by First Army succeeded in capturing important strategic locations such as Longstop Hill, Point 174 and Hill 609. This forced the Axis to withdraw resulting in large areas being abandoned to the Allies. Vulcan did not break out through into the open ground as planned, but it severely weakened the Axis forces, and became the first stage of the final Allied assault in the Tunisian campaign. Operation Strike commenced only a week after Vulcan had terminated, and within a few days allied forces broke through Axis frontlines, putting an end to the North Africa campaign.

Yevgeny Ananyevich Khaldei (Russian: Евгений Ананьевич Халдей; Ukrainian: Євген Ананійович Халдей, romanized: Yevhen Ananiyovych Khaldey; 23 March [O.S. 10 March] 1917 – 6 October 1997) was a Soviet naval officer and photographer. He is best known for his World War II photograph of a Soviet soldier raising a flag over the Reichstag in Berlin, the capital of the vanquished Nazi Germany, at the end of the war.

The 1948 Arab–Israeli War (15 May 1948 – 10 March 1949), also known as the First Arab–Israeli War, followed the civil war in Mandatory Palestine (29 November 1947 – 14 May 1948) as the second and final stage of the 1948 Palestine war. The civil war became a war of separate states with the Israeli Declaration of Independence on 14 May 1948, the end of the British Mandate for Palestine at midnight, and the entry of a military coalition of Arab states into the territory of Mandatory Palestine the following morning. The war formally ended with the 1949 Armistice Agreements which established the Green Line. Since the 1917 Balfour Declaration and the 1920 creation of the British Mandate of Palestine, and in the context of Zionism and the mass migration of European Jews to Palestine, there had been tension and conflict between Arabs, Jews, and the British in Palestine. On 29 November 1947, the United Nations General Assembly voted in favor of the United Nations Partition Plan for Palestine, proposing to divide the territory into an Arab state, a Jewish state, and an internationally administered corpus separatum for the cities of Jerusalem and Bethlehem. The land allocated to the Arab State included about 43% of Mandatory Palestine. The land allocated to the Jewish State, who constituted a third of the population, was 56% of Mandatory Palestine. While Jewish leaders in Palestine supported the plan, leaders of the Palestinian Arab community and in the broader Arab world did not. The following day, the conflict escalated into a civil war with attacks by Palestinian militias and mobs on Jewish areas. As the two communities battled, the British withdrew. In April 1948, Zionist forces launched an offensive codenamed Plan Dalet, during which they conquered and depopulated cities, villages, and territories in Mandatory Palestine in preparation for the establishment of a Jewish state. Just before the expiration of the British Mandate for Palestine, Zionist leaders announced the Israeli Declaration of Independence on 14 May 1948. The following morning, Egypt, Transjordan, Syria, and expeditionary forces from Iraq launched an invasion into Palestine, taking control of the Arab areas and attacking Israeli forces and settlements. The 10 months of fighting took place mostly on the territory of the British Mandate and in the Sinai Peninsula and southern Lebanon, interrupted by several truce periods. By the end of the war, the State of Israel controlled about 78% of the former territory of Mandatory Palestine: all of the area that the UN had proposed for a Jewish state, as well as almost 60% of the area proposed for an Arab state, including Jaffa, Lydda and Ramla (Ramle) area, Upper Galilee, some parts of the Negev, the west coast as far as Gaza City, and a wide strip along the Tel Aviv–Jerusalem road. Israel also took control of West Jerusalem, which was meant to be part of an international zone for Jerusalem and its environs. Transjordan took control of East Jerusalem and what became known as the West Bank, annexing it the following year. The territory known today as the Gaza Strip was occupied by Egypt. Expulsions of Palestinians, which had begun during the civil war, continued during the Arab-Israeli war.

The Troubles were an ethno-nationalist conflict in Northern Ireland that lasted from the late 1960s to 1998. Also known internationally as the Northern Ireland conflict, it is usually deemed to have ended with the Good Friday Agreement of 1998.

A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in cumulonimbus clouds. They are usually accompanied by strong winds and often produce heavy rain and sometimes snow, sleet, or hail, but some thunderstorms can produce little or no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction.
