August 30 in History

The foundation of Constantinople in 330 AD marks the conventional start of the Byzantine Empire, which fell to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title.

The Mirdasid dynasty, also called the Banu Mirdas, was an Arab Shia Muslim dynasty which ruled an Aleppo-based emirate in northern Syria and the western Jazira more or less continuously from 1014 until 1080.

Peter III of Aragon (In Aragonese, Pero; in Catalan, Pere; in Italian, Pietro; c. 1239 – 11 November 1285) was King of Aragon, King of Valencia (as Peter I), and Count of Barcelona (as Peter II) from 1276 to his death. At the invitation of some rebels, he conquered the Kingdom of Sicily and became King of Sicily (as Peter I) in 1282, pressing the claim of his wife, Constance II of Sicily, uniting the kingdom to the crown.

Pope Paul II (Latin: Paulus II; Italian: Paolo II; 23 February 1417 – 26 July 1471), born Pietro Barbo, was head of the Catholic Church and ruler of the Papal States from 30 August 1464 to his death in 1471. When his maternal uncle became Pope Eugene IV, Barbo switched from training to be a merchant to religious studies. His rise in the Church was relatively rapid. Elected pope in 1464, Paul amassed a great collection of art and antiquities.

A papal bull is a type of public decree, letters patent, or charter issued by the pope of the Catholic Church. It is named after the leaden seal (bulla) traditionally appended to authenticate it.

Guru Ram Das (Gurmukhi: ਗੁਰੂ ਰਾਮ ਦਾਸ, pronunciation: [gʊɾuː ɾaːmᵊ d̯aːsᵊ]; 24 September 1534 – 1 September 1581), sometimes spelled as Guru Ramdas, was the fourth of the ten Sikh gurus. He was born to a family based in Lahore. His birth name was Jetha, and he was orphaned at age seven; he thereafter grew up with his maternal grandmother in a village. At age 12, Bhai Jetha and his grandmother moved to Goindval, where they met Guru Amar Das, the third leader of Sikhism. The boy accepted the guru as his mentor, served him, and eventually joined his family by marrying his daughter. When it came time for Guru Amar Das to name his successor, he passed over his own sons and chose Bhai Jetha, citing his exemplary service, selfless devotion, and unquestioning obedience. Renamed Ram Das ("servant of God"), Bhai Jetha became the fourth Guru of Sikhism in 1574. He faced hostility from the sons of Guru Amar Das, and shifted his official base to lands identified by Guru Amar Das as Guru-ka-Chak. He founded the town of Ramdaspur, later renamed Amritsar and known as the holiest city of Sikhism. Unlike the first three Gurus, he appointed his own son as his successor. Whereas the first four Gurus were not related to their predecessors by descent, the fifth through tenth were all direct descendants of Guru Ram Das. He served until his death in 1581. He is remembered in the Sikh tradition for expanding the manji organization for clerical appointments and donation collections to theologically and economically support the Sikh movement. In a similar light to his predecessor, Guru Ram Das also encouraged widow remarriage.

Tokugawa Ieyasu (born Matsudaira Takechiyo; January 31, 1543 – June 1, 1616) was a Japanese samurai, daimyo and the founder and first shogun of the Tokugawa shogunate of Japan, which ruled from 1603 until the Meiji Restoration in 1868. He was the third of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as ally, vassal, and general of the Oda clan, and building up his strength under Oda Nobunaga. After Oda Nobunaga's death, Ieyasu was briefly a rival of Toyotomi Hideyoshi, before declaring his allegiance to Toyotomi and fighting on his behalf. Under Toyotomi, Ieyasu was relocated to the Kanto plains in eastern Japan, away from the Toyotomi power base in Osaka. He built his castle in the fishing village of Edo (now Tokyo). He became the most powerful daimyo and the most senior officer under the Toyotomi regime. Ieyasu preserved his strength during Toyotomi's failed attempts to conquer Korea. After Hideyoshi's death and the Battle of Sekigahara, Ieyasu seized power in 1600. He received appointment as shōgun in 1603, and voluntarily resigned from his position in 1605, although he still held the de facto control of government until his death in 1616. He implemented a set of careful rules known as the bakuhan system. This system used precisely graded rewards and punishments to encourage (or compel) the daimyo and samurai to live in peace with each other under the Tokugawa shogunate. Following his death, his successors shifted the government to Edo in 1638 and enacted the Sakoku policy of isolationism in 1639 which closed off Japan from the outside world for over 200 years until the Meiji era began in 1868.

James VI and I (James Charles Stuart; 19 June 1566 – 27 March 1625) was King of Scotland as James VI from 24 July 1567, and King of England and Ireland as James I from the union of the Scottish and English crowns on 24 March 1603, until his death in 1625. Though he long attempted to get both countries to adopt a closer political union, the kingdoms of Scotland and England remained sovereign states ruled by James in personal union, with their own parliaments, judiciaries and laws. James was the son of Mary, Queen of Scots, and a great-great-grandson of Henry VII, King of England and Lord of Ireland, and thus a potential successor to all three thrones. He acceded to the Scottish throne at the age of thirteen months, after his mother was forced to abdicate. Although his mother was a Catholic, James was raised as a Protestant. Four regents governed during his minority, which ended officially in 1578, though he did not gain full control of his government until 1583. In 1589, he married Anne of Denmark. Three of their children survived to adulthood: Henry Frederick, Elizabeth, and Charles. In 1603, James succeeded his cousin Elizabeth I, the last Tudor monarch of England and Ireland, who had died childless. He reigned in all three kingdoms for 22 years, a period known as the Jacobean era, until he died in 1625. After the Union of the Crowns in 1603, he based himself in England, returning to Scotland only once in 1617, and styled himself King of Great Britain and Ireland. He advocated for a single parliament for England and Scotland. During his reign, the Plantation of Ulster and the English colonisation of the Americas began. At 57 years and 246 days, James's reign in Scotland was the longest of any Scottish monarch. He achieved most of his aims in Scotland but faced great difficulties in England, including the Gunpowder Plot in 1605 and conflicts with the English Parliament. Under James, the "Golden Age" of Elizabethan literature and drama continued, with writers such as William Shakespeare, John Donne, Ben Jonson, and Francis Bacon contributing to a flourishing literary culture. James was a prolific writer, authoring works such as Daemonologie (1597), The True Law of Free Monarchies (1598), and Basilikon Doron (1599). He sponsored an early translation of the Bible into English (later named for him as the Authorized King James Version), and the 1604 revision of the Book of Common Prayer. Contemporary courtier Anthony Weldon claimed that James had been termed "the wisest fool in Christendom" (wise in small things, foolish otherwise), an epithet associated with his character ever since. Since the latter half of the 20th century, historians have tended to revise James's reputation and treat him as a serious and thoughtful monarch. He was strongly committed to a peace policy and tried to avoid involvement in religious wars, especially the Thirty Years' War that devastated much of Central Europe. He tried but failed to prevent the rise of hawkish elements in the English Parliament who desired war with Catholic Spain. The first English king of the House of Stuart, he was succeeded by his second son, Charles I.

In the Great Northern War (1700–1721) a coalition led by Russia successfully contested the supremacy of Sweden in Northern, Central and Eastern Europe. The initial leaders of the anti-Swedish alliance were Peter I of Russia, Frederick IV of Denmark–Norway and Augustus II the Strong of Saxony-Poland-Lithuania. Frederick IV and Augustus II were defeated by Sweden, under Charles XII, and forced out of the alliance in 1700 and 1706, respectively, but rejoined it in 1709 after the defeat of Charles XII at the Battle of Poltava. George I of Great Britain and the Electorate of Hanover joined the coalition in 1714 for Hanover and in 1717 for Britain, and Frederick William I of Brandenburg-Prussia joined it in 1715. Charles XII led the Swedish Army. Swedish allies included Holstein-Gottorp, several Polish magnates under Stanisław I Leszczyński (1704–1710) and Cossacks under the Ukrainian Hetman Ivan Mazepa (1708–1710). The Ottoman Empire temporarily hosted Charles XII of Sweden and intervened against Peter I. The war began when Denmark–Norway, Saxony and Russia, sensing an opportunity as Sweden was ruled by the young Charles XII, formed a coalition against Sweden. Denmark invaded Sweden's ally Holstein-Gottorp, while Saxony and Russia declared war on the Swedish Empire and attacked Swedish Livonia and Swedish Ingria, respectively. Sweden parried the Danes at Travendal (August 1700) and the Russians at Narva (November 1700), and in a counter-offensive pushed Augustus II's forces through the Polish–Lithuanian Commonwealth to Saxony, dethroning Augustus on the way (September 1706) and forcing him to acknowledge defeat in the Treaty of Altranstädt (October 1706). The treaty also secured the extradition and execution of Johann Reinhold Patkul, architect of the alliance seven years earlier. Meanwhile, the forces of Peter I had recovered from defeat at Narva and gained ground in Sweden's Baltic provinces, where they cemented Russian access to the Baltic Sea by founding Saint Petersburg in 1703. Charles XII moved from Saxony into Russia to confront Peter, but the campaign ended in 1709 with the destruction of the main Swedish army at the decisive Battle of Poltava (in present-day Ukraine) and Charles' exile in the Ottoman town of Bender. The Ottoman Empire defeated the Russian–Moldavian army in the Pruth River Campaign, but that peace treaty was in the end without great consequence to Russia's position. After Poltava, the anti-Swedish coalition revived and subsequently Hanover and Prussia joined it. The remaining Swedish forces in plague-stricken areas south and east of the Baltic Sea were evicted, with the last city, Tallinn, falling in the autumn of 1710. By 1714, Russia had occupied Finland. On 18 October 1709, Sweden received Denmark-Norway’s declaration of war, presented as a response to the alleged maltreatment of Danes by Sweden in Scania. Swedish victory at Helsingborg amounted to only a brief respite before ultimate defeat in the west. From June 1716, Denmark and Russia prepared a joint invasion of Sweden proper, which the Tsar envisioned as dealing the Swedish king a decisive blow. Earlier that year, Charles XII had invaded south-eastern Norway, but a string of successive defeats, together with the systematic disruption of Swedish logistics by the Norwegians, had forced him back towards the border. In June and July, a renewed offensive against Fredrikshald, or Halden, was frustrated by the combined efforts of the town's garrison and inhabitants. The campaign was finally abandoned after Tordenskjold, the Norwegian naval hero, captured almost the entire Swedish supply and transport fleet at Dynekilen, forcing Charles XII to finally retreat across the border. In the meantime, a Danish-Russian invasion force was assembling across the strait. Severe delays, however, pushed the operation into autumn and, together with growing distrust and strategic divergence between the allied monarchs, ultimately led to its cancellation. In 1718, Sweden launched a second and even larger campaign against Norway. Charles XII was ultimately killed in the trenches before Fredriksten, while a second Swedish field army was forced onto the Carolean Death March during its retreat from Trøndelag, losing most of its men. The failure of the Norwegian campaign constituted a severe strategic defeat for Sweden and effectively brought its offensive war to an end. The war ended with the defeat of Sweden, leaving Russia as the new dominant power in the Baltic region and as a new major force in European politics. The Western powers, Great Britain and France, became caught up in the separate War of the Spanish Succession (1701–1714), which broke out over the Bourbon Philip of Anjou's succession to the Spanish throne and a possible joining of France and Spain. The formal conclusion of the Great Northern War came with the Swedish-Hanoverian and Swedish-Prussian Treaties of Stockholm (1719), the Dano-Swedish Treaty of Frederiksborg (1720), and the Russo-Swedish Treaty of Nystad (1721). By these treaties Sweden ceded its exemption from the Sound Dues and lost the Baltic provinces and the southern part of Swedish Pomerania. The peace treaties also ended its alliance with Holstein-Gottorp. Hanover gained Bremen-Verden, Brandenburg-Prussia incorporated the Oder estuary (Stettin Lagoons), Russia secured the Baltic Provinces, and Denmark strengthened its position in Schleswig-Holstein. In Sweden, the absolute monarchy had come to an end with the death of Charles XII, and Sweden's Age of Liberty began.

Anne, Princess Royal (2 November [O.S. 22 October] 1709 – 12 January 1759) was the second child and eldest daughter of King George II of Great Britain and his consort Caroline of Ansbach. She was the wife of William IV, Prince of Orange, the first hereditary stadtholder of all seven provinces of the Dutch Republic. She was Regent of the Netherlands from 1751 until her death in 1759, exercising extensive powers on behalf of her son William V. She was known as an Anglophile, due to her English upbringing and family connections, but was unable to convince the Dutch Republic to enter the Seven Years' War on the side of the British. Princess Anne was the second daughter of a British sovereign to hold the title Princess Royal. In the Netherlands she was styled Anna van Hannover.

The Battle of Gross Jägersdorf (Gross-Jägersdorf; 30 August 1757) was a victory for the Russian force under Field Marshal Stepan Fyodorovich Apraksin over a smaller Prussian force commanded by Field Marshal Hans von Lehwaldt, during the Seven Years' War. This was the first battle in which Russia engaged during the Seven Years' War. Despite the tactical success, supply problems made a successful advance further into East Prussia impractical. Apraksin decided not to take Königsberg and ordered a withdrawal soon after the battle. Suspecting collusion between Apraksin and Chancellor Alexey Bestuzhev-Ryumin, who had opposed the invasion, Elizabeth of Russia removed Apraksin from command, ordered Bestuzhev-Ryumin to face trial for treason, and appointed William Fermor as the head of the army. Femor led the army back into East Prussia in the following year.

HMS Pandora was a 24-gun Porcupine-class sixth-rate post ship of the Royal Navy launched in May 1779. The vessel is best known for its role in hunting down the Bounty mutineers in 1790, which remains one of the best-known stories in the history of seafaring. Pandora was partially successful by capturing 14 of the mutineers, but wrecked on the Great Barrier Reef on the return voyage in 1791. HMS Pandora is considered to be one of the most significant shipwrecks in the Southern Hemisphere.

In the Vlieter incident of 30 August 1799 a Batavian Navy fleet under Schout-bij-nacht Samuel Story surrendered to the Royal Navy. The incident occurred during the Anglo-Russian invasion of Holland in the tidal trench between Texel and the mainland that was known as De Vlieter, near Wieringen.

The Convention of Cintra (or Sintra) was an agreement signed on 30 August 1808, during the Peninsular War. By the agreement, the defeated French were allowed to evacuate their troops from Portugal without further conflict. The convention was signed at the Palace of Queluz, in Queluz, Cintra, Estremadura.

The Battle of Kulm was fought near the town Kulm (Czech: Chlumec) and the village Přestanov (then called Priesten) in northern Bohemia. It was fought on 29–30 August 1813, during the War of the Sixth Coalition. A French corps under General Dominique Vandamme attacked Alexander Osterman-Tolstoy's Russian corps on 29 August. The next day, Friedrich von Kleist's Prussian corps hit Vandamme in the rear while Russian and Austrian reinforcements attacked the French front and left. Vandamme was defeated with the loss of between 13,000 and 25,000 men and 82 guns. Frederick William created an award for those who distinguished themselves in battle, the Kulm Cross.

The Creek War was a regional conflict between opposing Native American factions, European powers, and the United States during the early 19th century. The Creek War began as a conflict within the tribes of the Muscogee, but the United States quickly became involved. British traders and Spanish colonial officials in Florida supplied the Red Sticks with weapons and equipment due to their shared interest in preventing the expansion of the United States into regions under their control.

Melbourne ( MEL-bərn, locally [ˈmæɫbən] ) is the capital and most populous city of the Australian state of Victoria and the second-most populous city in Australia. The city's name generally refers to a 9,993-square-kilometre (3,858 sq mi) area, comprising an urban agglomeration of 30 local government areas. The name is also used specifically to refer to the local government area, also named the City of Melbourne, whose administrative area is centred on the Melbourne central business district and some immediate surrounds. The city occupies much of the northern and eastern coastlines of Port Phillip Bay. As of June 2025, the population of the city was 5.435 million, or 19% of the population of Australia. It is the southernmost city in the world with a population exceeding one million. Its inhabitants are known as "Melburnians". The area of Melbourne has been home to Aboriginal Victorians for over 40,000 years. Of the five peoples of the Kulin nation, the traditional custodians of the land encompassing Melbourne are the Boonwurrung, Woiwurrung and the Wurundjeri peoples. In 1803, a short-lived British penal settlement was established at Port Phillip, then part of the Colony of New South Wales. Melbourne was founded in 1835 with the arrival of free settlers from Van Diemen's Land (modern-day Tasmania). It was incorporated as a Crown settlement in 1837 and named after the then Prime Minister of the United Kingdom, William Lamb, 2nd Viscount Melbourne. Declared a city by Queen Victoria in 1847, it became the capital of the newly separated Colony of Victoria in 1851. During the 1850s Victorian gold rush, the city entered a lengthy boom period that, by the late 1880s, had transformed it into one of the largest and wealthiest metropolises in both Australia and the world. After the federation of Australia in 1901, Melbourne served as the interim seat of government of the new nation until Canberra became the permanent capital in 1927. Today, Melbourne is culturally diverse. It is a leading financial centre in the Asia-Pacific region, ranking 28th globally in the 2024 Global Financial Centres Index. The city's eclectic architecture blends Victorian-era structures, such as the World Heritage–listed Royal Exhibition Building, with a large skyline. Landmarks include the Melbourne Cricket Ground and the National Gallery of Victoria. Noted for its cultural heritage, the city gave rise to Australian rules football, Australian impressionism and Australian cinema, and is known for its street art, live music and theatre scenes. It hosts major annual sporting events, such as the Australian Grand Prix and the Australian Open Grand Slam, and also hosted the 1956 Summer Olympics. Melbourne ranked as the world's most liveable city on The Economist's measure for much of the 2010s. It was also voted the world's best city by Time Out in 2026. Melbourne Airport is the second-busiest airport in Australia and the Port of Melbourne is the nation's busiest seaport. Its main metropolitan rail terminus is Flinders Street station and its main regional rail and road coach terminus is Southern Cross station. It also has Australia's most extensive freeway network and the largest urban tram network in the world.

Houston is the most populous city in the U.S. state of Texas and the Southern United States. It is the fourth-most populous city in the United States, with a population of 2.3 million at the 2020 census. The Greater Houston metropolitan area, at 7.8 million residents, is the fifth-most populous metropolitan area in the nation and second-most populous in Texas. Located in Southeast Texas near Galveston Bay and the Gulf of Mexico, Houston is the county seat of Harris County. Covering a total area of 640.4 square miles (1,659 km2), it is the ninth largest city in the country and the largest whose municipal government is not consolidated with a county, parish, or borough. Although primarily located within Harris County, portions of the city extend into Fort Bend and Montgomery counties. Houston also functions as the southeastern anchor of the Texas Triangle megaregion.

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.

Julius Johannes Ludovicus Ritter von Payer (2 September 1841 – 29 August 1915), ennobled Ritter von Payer in 1876, was an officer of the Austro-Hungarian Army, mountaineer, arctic explorer, cartographer, painter, and professor at the Theresian Military Academy. He is chiefly known for the Austro-Hungarian North Pole expedition in 1872–1874 and the discovery of Franz Josef Land.

The Philippine Revolution was a war of independence waged by the revolutionary organization Katipunan against the Spanish Empire from 1896 to 1898. It was the culmination of the 333-year colonial rule of Spain in the archipelago. The Philippines was one of the last major colonies of the Spanish Empire, which had already suffered a massive decline in the 1820s. Cuba rebelled in 1895, and in 1898, the United States intervened and the Spanish soon capitulated. In June 1898, Philippine revolutionaries declared independence. However, it was not recognized by Spain, which later sold the islands to the United States in the Treaty of Paris of 1898. Led by Andrés Bonifacio, the Katipunan was formed in secrecy in 1892 in the wake of the nascent La Liga Filipina, an organization created by Filipino nationalist José Rizal and others in Spain with the goal of Philippine representation to the Spanish Parliament. Katipunan soon gained influence across the islands, and sought an eventual armed revolution. However, the revolution started prematurely in August 1896 upon its discovery by Spanish authorities in Manila. The organization quickly declared war against Spain in Caloocan. Early battles and skirmishes were centered around sieging the capital city of Manila led by Bonifacio himself, which ultimately failed. However, revolutionaries in the neighboring provinces fared better, particularly in Cavite, where rebels led by Mariano Álvarez and cousins Baldomero and Emilio Aguinaldo won early major victories. This disparity in success, along with multiple factors, contributed to the eventual power struggle from within Katipunan's leadership. Two factions formed: Bonifacio's Magdiwang and Aguinaldo's Magdalo. This struggle culminated in the 1897 elections in Tejeros, which saw Emilio Aguinaldo elected as president in absentia. Bonifacio nullified the results after a Magdalo member questioned his election as the Secretary of the Interior. This resulted in a schism, with Bonifacio's supporters alleging that the elections were fraudulent, and Bonifacio himself refusing to recognize the results. In April 1897, Aguinaldo ordered the arrest of Bonifacio. A trial was set in Maragondon, where the Magdalo-led jury found Bonifacio and his brother Procopio guilty of treason and sentenced both of them to death. Despite calls for commuting the sentence for the sake of national unity, the brothers were executed in May 1897. Later that year, Aguinaldo's government and Spanish authorities signed the Pact of Biak-na-Bato, which temporarily reduced hostilities. Filipino revolutionary officers exiled themselves to Hong Kong. However, the hostilities never completely ceased. On April 21, 1898, after the sinking of the USS Maine in Havana Harbor, the United States declared war against Spain, starting the Spanish-American War. On May 1, the United States Asiatic Squadron, under George Dewey, decisively defeated the Spanish Navy in the Battle of Manila Bay, effectively seizing control of the area surrounding Manila. On May 19, Aguinaldo, unofficially allied with the United States, returned to the Philippines and resumed attacks against the Spaniards. By June, the rebels had gained control of nearly the entirety of the countryside, while the cities remained under Spanish control. On June 12, Aguinaldo issued the Philippine Declaration of Independence in Kawit. Although this signified the end date of the revolution, neither Spain nor the United States recognized Philippine independence. The Treaty of Paris was signed between Spain and the United States, formally ending the war and the Spanish rule to the islands. Despite attempts by the Filipino government, there were no Filipinos in the treaty. On February 4, 1899, fighting broke out between the Filipino and American forces, beginning the Philippine–American War. Aguinaldo immediately declared war, ordering "that peace and friendly relations with the Americans be broken and that the latter be treated as enemies". In June 1899, the First Philippine Republic formally declared war against the United States, which ended with the Philippine Organic Act in July 1902. As a result, the islands become an unincorporated territory of the United States. A commonwealth government was formed in 1935, with Manuel L. Quezon, Aguinaldo's aide-de-camp during the revolution, assuming the presidency. The Philippines was intended to become independent after a ten-year commonwealth period but was cut short by the advent of the Second World War in the Pacific. The country finally became fully independent on July 4, 1946, 50 years after the start of the revolution.

The Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. It is famous for the exceptional preservation of the soft parts of its fossils. At c.505 million years old (middle Cambrian), it is one of the earliest fossil beds containing soft-part imprints. The rock unit is a black shale and crops out at several localities near the town of Field in Yoho National Park and the Kicking Horse Pass. Another outcrop is in Kootenay National Park 42 km to the south.

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 resulted in an estimated 15 to 22 million deaths, including those in war crimes and genocides. The war also helped spread the Spanish flu pandemic. The conflict saw important developments in weaponry, including the first large-scale use of machine guns, artillery, aircraft, chemical weapons, and tanks.

Sir Ernest Henry Shackleton was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.

The Thái Nguyên Uprising (Vietnamese: Khởi nghĩa Thái Nguyên) or officially Thái Nguyên Mutiny (Vietnamese: Binh biến Thái Nguyên) in 1917 has been described as the "largest and most destructive" anti-French rebellion in Vietnam (then part of French Indochina) between the Pacification of Tonkin in the 1880s and the Nghetinh Rebellion of 1930–31.

Fanny Efimovna Kaplan (Russian: Фанни Ефимовна Каплан; real name Feiga Haimovna Roytblat, Фейга Хаимовна Ройтблат; 10 February 1890 – 3 September 1918) was a Russian Socialist-Revolutionary who attempted to assassinate Vladimir Lenin. She was arrested and executed by the Cheka in 1918. Born into a Jewish family, Kaplan served a sentence of hard labor during the tsarist years for her revolutionary activities. As a member of the Socialist Revolutionary Party, Kaplan viewed Lenin as a "traitor to the revolution" when the Bolsheviks enacted one-party rule and banned her party. On 30 August 1918, she approached Lenin, who was leaving a Moscow factory, and fired three shots. Lenin was badly injured by two of the shots she fired. Interrogated by the Cheka, she refused to name any accomplices before being executed. The Kaplan attempt and the Moisei Uritsky assassination were used by the government of Soviet Russia for the reinstatement of capital punishment, which had been abolished by the Russian Provisional Government in March 1917.

The Battle of Dumlupınar (Greek: Μάχη του Τουμλού Μπουνάρ, romanized: Máchi tou Toumloú Bounár, Turkish: Dumlupınar (Meydan) Muharebesi, lit. 'Dumlupınar (Field) Battle'), also known as Field Battle of the Commander-in-Chief (Turkish: Başkumandanlık Meydan Muharebesi) in Turkey, was one of the important battles in the Greco-Turkish War (1919–1922) (part of the Turkish War of Independence). The battle was fought from 26 to 30 August 1922 near Dumlupınar, Kütahya in Turkey.

RMS Queen Mary is a former British ocean liner that operated primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard Line. It is currently a hotel, museum, and convention space in Long Beach, California, United States. It is on the US National Register of Historic Places and member of Historic Hotels of America, the official program of the National Trust for Historic Preservation. Built by John Brown & Company in Clydebank, Scotland, she was subsequently joined by RMS Queen Elizabeth in Cunard's two-ship weekly express service between Southampton, Cherbourg and New York. These "Queens" were the British response to the express superliners built by German, Italian, and French companies in the late 1920s and early 1930s. Queen Mary sailed on her maiden voyage on 27 May 1936 and won the Blue Riband that August; she lost the title to SS Normandie in 1937 and recaptured it in 1938, holding it until 1952, when the new SS United States claimed it. With the outbreak of World War II, she was converted into a troopship and ferried Allied soldiers during the conflict. On one voyage in 1943, she carried over 16,600 people, setting a record for the most people carried on one vessel at the same time that still stands. Following the war, Queen Mary returned to passenger service and, along with Queen Elizabeth, commenced the two-ship transatlantic passenger service for which the two ships were initially built. The pair dominated the transatlantic passenger transportation market until the dawn of the jet age in the late 1950s. By the mid-1960s, Queen Mary was ageing and operating at a loss. After several years of decreased profits, Cunard officially retired the Queen Mary from service in 1967. Bought by the City of Long Beach to function as a restaurant, museum, and hotel, she left Southampton for the last time on 31 October 1967 and sailed to the Port of Long Beach where she was permanently moored. After undergoing extensive refurbishment and modifications, Queen Mary opened to the public in 1971 and has remained operational since.
