August 17 in History

The Byzantine–Bulgarian wars were a series of conflicts fought between the Byzantine Empire and the Bulgarian Empire which began already in the late 5th century when the Bulgars defeated a 15.000 Roman army led by Magister Aristus (499 AD). The Bulgars permanently conquered parts of the Balkan Peninsula after 680 AD. The Byzantine and First Bulgarian Empire continued to clash over the next century with varying success, until the Bulgarians, led by Krum, inflicted a series of crushing defeats on the Byzantines. After Krum died in 814, his son Omurtag negotiated a thirty-year peace treaty. Simeon I had multiple successful campaigns against the Byzantines during his rule from 893 to 927. His son Peter I negotiated another long-lasting peace treaty. His rule was followed by a period of decline of the Bulgarian state. In 971 John I Tzimiskes, the Byzantine emperor, subjugated much of the weakening Bulgarian Empire by defeating Boris II and capturing Preslav, the Bulgarian capital. Samuel managed to stabilize the Bulgarian state with its center around the town of Prespa. Near the end of his rule, the Byzantines regained the upper hand, and under Basil II they won the Battle of Kleidion and completely conquered Bulgaria in 1018. There were rebellions against Byzantine rule from 1040 to 1041, and in the 1070s and the 1080s, but these failed. In 1185, however, Theodore Peter and Ivan Asen started a revolt, and the weakening Byzantine Empire, facing internal dynastic troubles of its own, was unable to quash the revolt. After the army of the Fourth Crusade conquered Constantinople in 1204, Kaloyan, the Bulgarian emperor, tried to establish friendly relations with the crusaders. However, the newly created Latin Empire spurned any offer of alliance with the Bulgarians. Because of his cold reception, Kaloyan allied with the Nicaeans, which reduced the crusaders' power in the area. Although his nephew Boril allied with the Latin Empire, Boril's successors sided with the Nicaeans, despite a few continuing attacks from them. After the Latin Empire collapsed, the Byzantines, took advantage of the Bulgarian civil war and captured portions of Thrace, however the Bulgarian emperor Theodore Svetoslav retook these lands. The Byzantine-Bulgarian relations continued to fluctuate until the Ottoman Turks captured the Bulgarian capital in 1393 and the Byzantine capital in 1453.

The Georgenberg Pact (also called the Georgenberg Compact, German: Georgenberger Handfeste) was a treaty signed between Duke Leopold V of Austria and Duke Ottokar IV of Styria on 17 August 1186 at Enns Castle on the Georgenberg mountain. The treaty consisted of two parts. The first part was an agreement under which the childless and deathly ill Ottokar IV, the first and last Styrian duke from the Otakar dynasty who had contracted leprosy while on the Third Crusade, was to pass his duchy to the Austrian duke Leopold V and to his son Frederick from the Franconian Babenberg dynasty, under the stipulation that Austria and Styria would henceforth remain united forever. The second part consists of a delineation of rights of the Styrian estates and citizens. It has been incorrectly called by English-speaking historians a "Styrian Magna Carta", for it sought to maintain the rights of the Styrian ministeriales in anticipation of the Babenberg acquisition. The territory of Styria at the time went far beyond the modern Austrian state of Styria, and included lands not only in modern Slovenia (Lower Styria), but also in Upper Austria, more precisely the Traungau region around the cities of Wels and Steyr, as well as the present-day districts of Wiener Neustadt and Neunkirchen in Lower Austria. The case of succession came to pass upon Ottokar's death in 1192, Styria has since then remained connected to Austria. The treaty was acknowledged by Emperor Frederick II in 1237. It was continued under the rule of the Habsburg dynasty after the line of Babenberg dukes became extinct in 1246; despite several interludes when the Styrian lands were ruled by Inner Austrian cadet branches. The Georgenberg Pact thus was the first step towards the creation of a complex of "hereditary lands" of the Habsburg monarchy. The Pact formed an integral part of the Austrian constitution until the Revolutions of 1848. The original document is kept at the Styrian State Archive in Graz.

Karl Thopia sometimes written as Charles Thopia, was an Albanian feudal prince and warlord who ruled Albanian domains from 1358 until the first Ottoman conquest of Albania in 1388. Thopia usually maintained good relations with the Roman Curia.

The Hundred Years' War (French: Guerre de Cent Ans; 1337–1453) was a series of conflicts between the kingdoms of England and France and a civil war in France during the late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving different factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years. However, it was an intermittent conflict which was frequently interrupted by external factors, such as the Black Death, and several years of truces. The Hundred Years' War was a significant conflict in the Middle Ages. During the war, five generations of kings from two rival dynasties fought for the throne of France, then the wealthiest and most populous kingdom in Western Europe. The war had a lasting effect on European history: both sides produced innovations in military technology and tactics, including professional standing armies and artillery, that permanently changed European warfare. Chivalry reached its height during the conflict and subsequently declined. Stronger national identities took root in both kingdoms, which became more centralized and gradually emerged as global powers. The term "Hundred Years' War" was adopted by later historians and included dynastically related conflicts in Spain and Belgium, resulting in the longest military conflict in European history. The war is commonly divided into three phases, separated by truces: the Edwardian War (1337–1360), the Caroline War (1369–1389), and the Lancastrian War (1415–1453). Each side drew many allies into the conflict, with English forces initially prevailing; however, the French forces under the House of Valois ultimately retained control over the Kingdom of France. The French and English monarchies thereafter remained separate, despite the monarchs of England and Great Britain styling themselves as sovereigns of France until 1802.

Cesare Borgia (13 September 1475 – 12 March 1507) was an Italian cardinal deacon and later a condottiero, as well as a member of the Spanish House of Borgia. He was the illegitimate son of Pope Alexander VI and sibling to Lucrezia Borgia. After initially entering the Church and becoming a cardinal on his father's election to the papacy, he resigned his diaconal profession after his brother was murdered in 1497. He was employed as a condottiero for King Louis XII of France around 1500, and occupied both Milan and Naples during the Italian Wars. At the same time, he carved out a state for himself in Central Italy, but he was unable to retain power for long after his father's death. His quest for political power was a major inspiration for The Prince by the renowned Florentine historian, Niccolò Machiavelli.

The Battle of Sampford Courtenay was one of the chief military engagements in the Western Rebellion of 1549.

The Catholic Church, also called the Roman Catholic Church, is the largest Christian church, with an estimated 1.28 to 1.41 billion baptized members worldwide as of 2026. It consists of 24 autonomous churches. The largest one of these churches is the Latin Church. Besides it, there are 23 smaller Eastern Catholic Churches. Together, the Latin Church and Eastern Catholic churches are organized into nearly 3,500 dioceses and eparchies governed by bishops. Throughout history, the church has had a large role in the development of Western civilization. Catholic communities are present worldwide through missions, immigration, and conversions. The majority of Catholics live in the Global South, reflecting rapid demographic growth in Africa, Asia, and Latin America, as well as secularization in parts of Europe and North America.

The Eighty Years' War or Dutch Revolt (c. 1566/1568–1648) was an armed conflict in the Habsburg Netherlands between disparate groups of rebels and the Spanish government. The causes of the war included the Reformation, centralisation, excessive taxation, and the rights and privileges of the Dutch nobility and cities. After the initial stages, Philip II of Spain, the sovereign of the Netherlands, deployed his armies and regained control over most of the rebel-held territories. However, widespread mutinies in the Spanish army caused a general uprising. Under the leadership of the exiled William the Silent, the Catholic and Protestant-dominated provinces sought to establish religious peace while jointly opposing the king's regime with the Pacification of Ghent, but the general rebellion failed to sustain itself. Despite steady military and diplomatic successes by the Governor of Spanish Netherlands and General for Spain, the Duke of Parma, the Union of Utrecht continued their resistance, proclaiming their independence through the 1581 Act of Abjuration and establishing the Calvinist-dominated Dutch Republic in 1588. In the Ten Years thereafter, the Republic (whose heartland was no longer threatened) made conquests in the north and east and received diplomatic recognition from France and England in 1596. The Dutch colonial empire emerged, which began with Dutch attacks on Portugal's overseas territories. Facing a stalemate, the two sides agreed to a Twelve Years' Truce in 1609; when it expired in 1621, fighting resumed as part of the broader Thirty Years' War. An end was reached in 1648 with the Peace of Münster when Spain retained the Southern Netherlands and recognised the Dutch Republic as an independent country.

Sir Walter Raleigh (; c. 1553 – 29 October 1618) was an English statesman, soldier, writer and explorer. One of the most notable figures of the Elizabethan era, he played a leading part in English colonisation of North America, suppressed rebellion in Ireland, helped defend England against the Spanish Armada and held political positions under Elizabeth I. Raleigh was born to a landed gentry family of Protestant faith in Devon, the son of Walter Raleigh and Catherine Champernowne, daughter of Sir Philip Champernowne. He was the younger half-brother of Sir Humphrey Gilbert and a cousin of Sir Richard Grenville. Little is known of his early life, though in his late teens he spent some time in France taking part in the religious civil wars. In his 20s he took part in the suppression of rebellion in the colonisation of Ireland; he also participated in the siege of Smerwick. Later, he became a landlord of property in Ireland and mayor of Youghal in east Munster. Raleigh rose rapidly in the favour of Queen Elizabeth I and was knighted in 1585. He was granted a royal patent to explore Virginia, paving the way for future English settlements. In 1591, he secretly married Elizabeth Throckmorton, one of the Queen's ladies-in-waiting, without the Queen's permission, for which he and his wife were sent to the Tower of London. After his release, they retired to his estate at Sherborne, Dorset. In 1594, Raleigh heard of a "City of Gold" in South America and sailed to find it, publishing an exaggerated account of his experiences in a book that contributed to the legend of "El Dorado". After Queen Elizabeth died in 1603, Raleigh was again imprisoned in the Tower, this time for being involved in the Main Plot against King James I, who was not favourably disposed towards him. In 1616, he was released to lead a second expedition in search of El Dorado. During the expedition, men led by his top commander sacked a Spanish outpost, in violation of both the terms of his pardon and the 1604 peace treaty with Spain. Raleigh returned to England and, to appease the Spanish, he was arrested and executed in 1618.

The Parliamentarians, commonly called Roundheads by their enemies and in modern historiography, were the supporters of the Parliament of England during the English Civil War (1642–1651). They fought against King Charles I of England and his supporters, known as the Cavaliers or Royalists, who claimed rule by absolute monarchy and the principle of the divine right of kings. The goal of the Roundheads was to give to Parliament the supreme control over executive administration of England.

The Austro-Turkish War (1716–1718) was fought between the Habsburg monarchy and the Ottoman Empire. The 1699 Treaty of Karlowitz was not an acceptable permanent agreement for the Ottoman Empire. Twelve years after Karlowitz, it began the long-term prospect of taking revenge for its defeat at the Battle of Vienna in 1683. First, the army of Turkish Grand Vizier Baltacı Mehmet defeated Peter the Great's Russian Army in the Russo-Turkish War (1710–1713). Then, during the Ottoman–Venetian War (1714–1718), Ottoman Grand Vizier Damat Ali reconquered the Morea from the Venetians. As the guarantor of the Treaty of Karlowitz, the Austrians threatened the Ottoman Empire, which caused it to declare war in April 1716. On 2 August 1716, the first engagement of the war took place at the Battle of Karlowitz, which resulted in an Ottoman victory. Three days later, Prince Eugene of Savoy defeated the Turks at the Battle of Petrovaradin. The Banat and its capital, Temesvár, were conquered by Prince Eugene in October 1716. The following year, after the Austrians captured Belgrade, the Turks sought peace, and the Treaty of Passarowitz was signed on 21 July 1718. The Habsburgs gained control of Lower Syrmia, the city of Temesvár (the last Ottoman fortress in Hungary) and its region (establishing the Banat of Temeswar), and also gained Belgrade with portions of central Serbia and Bosnian sections of Posavina. Principality of Wallachia (an autonomous Ottoman vassal) ceded Oltenia (Lesser Wallachia) to the Habsburg monarchy, which established the Banat of Craiova. The Turks retained control only of the territory south of the Danube river. The pact stipulated for Venice to surrender the Morea to the Ottomans, but it retained the Ionian Islands and also made some minor gains in border regions of Ottoman Bosnia, thus extending the Venetian Dalmatia.

Ioan Giurgiu Patachi (or Latin: Ioannes Nemes de Pataki, 1680–1727) was Bishop of Fogaras and Primate of the Romanian Greek Catholic Church from 1721 to his death in 1727.

Pope Benedict XIV (Latin: Benedictus XIV; Italian: Benedetto XIV; 31 March 1675 – 3 May 1758), born Prospero Lorenzo Lambertini, was head of the Catholic Church and leader of the Papal States from 17 August 1740 to his death on 3 May 1758. His intellectualism and advocacy of science education earned him the nickname "the Enlightenment Pope". Perhaps one of the best scholars to sit on the papal throne, yet often overlooked, he promoted scientific learning, the Baroque arts, reinvigoration of Thomism, and the study of the human form. Firmly committed to carrying out the decrees of the Council of Trent and Catholic teaching, Benedict removed changes previously made to the Breviary, sought peacefully to reverse growing secularism in European courts, invigorated ceremonies with great pomp, and throughout his life and his reign published numerous theological and ecclesiastical treatises. In governing the Papal States, he reduced taxation on some products, but also raised taxes on others; he also encouraged agriculture and supported free trade within the Papal States. A scholar, he created the Sacred and Profane Museums, now part of the present Vatican Museums. He can be considered a polymath due to his numerous studies of ancient literature, his publishing of ecclesiastical books and documents, his interest in the study of the human body, and his devotion to art and theology. Towards the end of his papacy Benedict XIV was forced to contend with issues surrounding the Society of Jesus. He expelled them from Portugal at the behest of Joseph I in 1758, just before his death. The papacy reluctantly acceded to the anti-Jesuit demands while providing minimal theological justification for the suppressions. Horace Walpole described him as "loved by papists, esteemed by Protestants, a priest without insolence or interest, a prince without favorites, a pope without nepotism, an author without vanity, a man whom neither intellect nor power could corrupt."

Ridolfo Luigi Boccherini (, also US: ; Italian: [riˈdɔlfo luˈiːdʒi bokkeˈriːni] ; 19 February 1743 – 28 May 1805) was an Italian composer and cellist of the Classical era whose music retained a courtly and galante style even while he matured somewhat apart from the major classical musical centers. He is best known for the minuet from his String Quintet in E, Op. 11, No. 5 (G 275), and the Cello Concerto in B♭ major (G 482). The latter work was long known in the heavily altered version by German cellist and prolific arranger Friedrich Grützmacher, but has recently been restored to its original version. He is also particularly well known for his Musica notturna delle strade di Madrid (Night Music of the Streets of Madrid). Boccherini's output also includes several guitar quintets. The final movement of the Guitar Quintet No. 4 in D (G 448) is a fandango, a lively Spanish dance.

Vietnam, officially the Socialist Republic of Viet Nam (SRV), is a country at the eastern edge of Mainland Southeast Asia. With an area of about 331,000 square kilometres and a population of over 102 million, it is the world's 16th-most populous country. One of two communist states in Southeast Asia, Vietnam is bordered by China to the north, and Laos and Cambodia to the west; it lies along the Gulf of Thailand to the southwest and the South China Sea to the east, where it has shared and disputed maritime borders with other countries. Its capital is Hanoi, while its largest city is Ho Chi Minh City.

Robert Fulton (November 14, 1765 – February 24, 1815) was an American engineer and inventor who is widely credited with developing the world's first commercially successful steamboat, the North River Steamboat (also known as Clermont). In 1807, that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of 300 nautical miles (560 kilometers), in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers. Fulton became interested in steam engines and the idea of steamboats in 1777 when he was around age 12 and visited state delegate William Henry of Lancaster, Pennsylvania, who was interested in this topic. Henry had learned about inventor James Watt and his Watt steam engine on an earlier visit to England. In 1800, Fulton had been commissioned by Napoleon Bonaparte, leader of France, to attempt to design a submarine; he then produced Nautilus, the first practical submarine in history. Fulton is also credited with inventing some of the world's earliest naval torpedoes for use by the Royal Navy.

The Finnish War was fought between the Kingdom of Sweden and the Russian Empire from 21 February 1808 to 17 September 1809 as part of the Napoleonic Wars. As a result of the war, the eastern third of Sweden was established as the autonomous Grand Duchy of Finland within the Russian Empire. Other notable effects were the Swedish parliament's adoption of a new constitution and the establishment of the House of Bernadotte, the new Swedish royal house, in 1818.

William I (Willem Frederik; 24 August 1772 – 12 December 1843) was King of the Netherlands and Grand Duke of Luxembourg from 1815 until his abdication in 1840. Born as the son of William V, Prince of Orange, the last stadtholder of the Dutch Republic, and Wilhelmina of Prussia, William experienced significant political upheavals early in life. He fought against the French invasion during the Flanders campaign, and after the Batavian Revolution in 1795, his family went into exile. He briefly ruled the Principality of Nassau-Orange-Fulda before Napoleon's French troops' occupation forced him out of power. Following the defeat of Napoleon in 1814, William was invited back to the Netherlands, where he proclaimed himself Sovereign Prince of the United Netherlands. In 1815, William raised the Netherlands to a kingdom and concurrently became the grand duke of Luxembourg. His reign saw the adoption of a new constitution, which granted him extensive powers. He was a strong proponent of economic development, founding several universities and promoting trade. However, his efforts to impose the Reformed faith and the Dutch language in the mostly Catholic and partly French-speaking southern provinces, combined with economic grievances, sparked the Belgian Revolution in 1830. Unable to suppress the rebellion, William ultimately accepted Belgian independence in 1839 under the Treaty of London. William's later years were marked by dissatisfaction with constitutional changes and personal reasons, leading to his abdication in 1840 in favor of his son, King William II. He spent his final years in Berlin, where he died in 1843.

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom. It meets at the Palace of Westminster in London. It is bicameral, consisting of the House of Commons and the House of Lords, with the sovereign forming a third constitutional element. Acting together to legislate, these constitute the King-in-Parliament. Legislative authority has been devolved to the Scottish Parliament, Welsh Parliament, and Northern Ireland Assembly to differing degrees, while the UK Parliament retains authority to legislate in reserved matters and the power to legislate in devolved areas.

The American Indian Wars, also known as the American Frontier Wars, and the Indian Wars, were initially fought by European colonial empires, the United States, and briefly the Confederate States of America and Republic of Texas against various American Indian tribes in North America. These conflicts occurred from the time of the earliest colonial settlements in the 17th century until the end of the 19th century. The various conflicts resulted from a wide variety of factors, the most common being the desire of settlers and governments for tribal lands. The European powers and their colonies enlisted allied Indian tribes to help them conduct warfare against each other's colonial settlements. After the American Revolution, many conflicts were local to specific states or regions and frequently involved disputes over land use; many involved retaliatory violence. As American settlement expanded westward after the American Revolution, conflicts between the United States and Native American nations increased in scale and frequency. A major turning point came during the War of 1812, when Native confederacies in the Old Northwest and the Southern United States allied with the British against the United States. Following the war, armed resistance continued in some regions, but relations between the United States and Native nations were increasingly governed through treaties that transferred large areas of Indigenous land to the United States. Historians have noted that the United States frequently failed to uphold treaty obligations, contributing to recurring disputes and further conflict. The Indian Removal Act of 1830 authorized the president to negotiate treaties exchanging Native American lands east of the Mississippi River for lands in the west. Although the act itself provided for negotiated removals, federal and state authorities subsequently used a combination of treaties, political pressure, and coercion to relocate many Native nations from the southeastern United States to Indian Territory. The resulting removals, including the Trail of Tears, transferred millions of acres of Indigenous land to the United States and opened much of the Southeast to American settlement. As American settlement expanded across the Great Plains and the Western United States, the federal government increasingly confined Native peoples to Indian reservations through treaties, military campaigns, and congressional legislation. Native American tribes and confederacies often achieved significant military victories against American settlers and soldiers, but generally lacked the population, resources, and logistical capacity to sustain prolonged resistance against the expanding United States. Some scholars have characterized aspects of United States policies toward Native Americans, including forced removals, warfare, and reservation policies, as constituting genocide against Native Americans. Other scholars dispute the application of the term genocide to the American Indian Wars as a whole, arguing that the conflicts varied significantly across time and place.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States. The South saw slavery as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the abolition of slavery, freeing four million African Americans.

Charleston is the most populous city in the U.S. state of South Carolina. The city lies just south of the geographical midpoint of South Carolina's coastline on Charleston Harbor, an inlet of the Atlantic Ocean formed by the confluence of the Ashley, Cooper, and Wando rivers. Charleston had a population of 150,227 at the 2020 census, while the Charleston metropolitan area, comprising Berkeley, Charleston, and Dorchester counties, has an estimated 870,000 residents. It ranks as the third-most-populous metropolitan area in the state and the 71st-most-populous in the U.S. It is the county seat of Charleston County.

The Battle of Gainesville was an American Civil War engagement fought on August 17, 1864, when a Confederate force defeated Union detachments from Jacksonville, Florida. The result of the battle was the Confederate occupation of Gainesville for the remainder of the war.

The Grand Duchy of Baden was a German polity on the east bank of the Rhine. It originally existed as a sovereign state from 1806 to 1871 and later as part of the German Empire until 1918.

Wilhelm Richard Wagner was a German composer, theatre director, essayist, and conductor, best known for his operas, although his mature works are often referred to as music dramas. Unlike most composers, Wagner wrote both the libretti and the music for all of his stage works. He first achieved recognition with works in the Romantic tradition of Carl Maria von Weber and Giacomo Meyerbeer, but revolutionised the genre through his concept of the Gesamtkunstwerk, which sought to unite poetic, musical, visual, and dramatic elements. In that approach, the drama unfolds as a continuously sung narrative, with the music evolving organically from the text rather than alternating between arias and recitatives. Wagner outlined those ideas in a series of essays published between 1849 and 1852, most fully realising them in the first half of his four-opera cycle Der Ring des Nibelungen.

The Dominican Republic is an island country on the eastern part of the Caribbean island of Hispaniola in the Greater Antilles of the Caribbean Sea in the North Atlantic Ocean. It shares a maritime border with Puerto Rico to the east and a land border with Haiti to the west, occupying the eastern five-eighths of Hispaniola which, along with Saint Martin, is one of only two islands in the Caribbean shared by two sovereign states. In the Antilles, the country is the second-largest by area after Cuba at 48,671 square kilometers (18,792 sq mi) and the second most populous after Haiti with approximately 11.4 million people in 2024, of whom 3.6 million reside in the metropolitan area of Santo Domingo, the capital city.

The death of Bridget Driscoll (née Swift; c. 1851 – 17 August 1896) was the first recorded case of a pedestrian killed in a collision with a motor car in Great Britain. Driscoll was born in Ireland but living in Croydon, Surrey with her husband and children at the time of her death. She had planned a three-day trip to London to attend a League of the Cross festival. She was in the company of her teenage daughter May and her friend Elizabeth Murphy and was crossing Dolphin Terrace in the grounds of the Crystal Palace in London when she was struck by the driver of a car belonging to the Anglo-French Motor Carriage Company that was being used to give demonstration rides. One witness described the car as being driven at "a reckless pace, in fact, like a fire engine". Although the car's maximum speed was 8 miles per hour (13 km/h), it had been limited deliberately to 4 miles per hour (6.4 km/h), the speed at which the driver, Arthur James Edsall of Upper Norwood, claimed to have been travelling. His passenger, Alice Standing of Forest Hill, alleged he modified the engine to allow the car to go faster, but another taxicab driver examined the car and said it was incapable of exceeding 4.5 miles per hour (7.2 km/h) because of a low-speed engine belt. The collision happened just a few weeks after a new act of parliament had increased the speed limit for cars to 14 miles per hour (23 km/h), from 2 miles per hour in towns and 4 miles per hour in the countryside. The jury returned a verdict of "accidental death" after an inquest lasting some six hours. The coroner, Percy Morrison (Croydon division of Surrey), said he hoped "such a thing would never happen again". The Royal Society for the Prevention of Accidents estimated 550,000 people had been killed on UK roads by 2010.

Pike Place Market is a public market in Seattle, Washington, United States. It opened on August 17, 1907, and is one of the older continuously operated public farmers' markets in the United States. Overlooking the Elliott Bay waterfront on Puget Sound, it serves as a place of business for many small farmers, craftspeople and merchants. It is named for its central street, Pike Place, which runs northwest from Pike Street to Virginia Street on the western edge of Downtown Seattle. Pike Place Market is Seattle's most popular tourist destination, with more than 20 million annual visitors.

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 contributed to the spread of 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.

Leo Max Frank was an American lynching victim wrongly convicted of the murder of 13-year-old Mary Phagan, an employee in a factory in Atlanta, Georgia, where he was the superintendent. Frank's trial, conviction, and unsuccessful appeals attracted national attention. His kidnapping from prison and lynching became the focus of social, regional, political, and racial concerns, particularly regarding antisemitism. Modern researchers agree that Frank was innocent.

The 1915 Galveston hurricane was a tropical cyclone that caused extensive damage in the Galveston area in August 1915. Widespread damage was also documented throughout its path across the Caribbean Sea and the interior of the United States. Due to similarities in strength and trajectory, the storm drew comparisons with the deadly 1900 Galveston hurricane. While the newly completed Galveston Seawall mitigated a similar-scale disaster for Galveston, numerous fatalities occurred along unprotected stretches of the Texas coast due to the storm's 16.2 ft (4.9 m) storm surge. Overall, the major hurricane inflicted at least $30 million in damage and killed 403–405 people. A demographic normalization of landfalling storms suggested that an equivalent storm in 2005 would cause $68.0 billion in damage in the United States.

The Kingdom of Romania was a constitutional monarchy that existed from 25 March [O.S. 13 March] 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I, until 30 December 1947 with the abdication of King Michael I and the Romanian Parliament proclamation of the Romanian People's Republic.

The Bolsheviks, led by Vladimir Lenin, were a radical faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split with the Mensheviks at the Second Party Congress in 1903. The Bolshevik party, formally established in 1912, seized power in Russia in the October Revolution of 1917 and was later renamed the Russian Communist Party, All-Union Communist Party, and ultimately the Communist Party of the Soviet Union. Its ideology, based on Leninist and later Marxist–Leninist principles, became known as Bolshevism.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many engaging in total war on an unprecedented scale. World War II was the deadliest conflict in history, causing the deaths of 60 to 75 million people, a majority of whom were civilians. Millions died as a result of massacres, starvation, disease, and genocides including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Eighth Air Force (Air Forces Strategic) is a numbered air force (NAF) of the United States Air Force's Air Force Global Strike Command (AFGSC). It is headquartered at Barksdale Air Force Base, Louisiana. The command serves as Air Forces Strategic – Global Strike, one of the air components of United States Strategic Command (USSTRATCOM). The Eighth Air Force includes the heart of America's heavy bomber force: the Northrop Grumman B-2 Spirit stealth bomber, the Rockwell B-1 Lancer supersonic bomber, and the Boeing B-52 Stratofortress heavy bomber aircraft.

The Seventh Army was a United States army created during World War II that evolved into the United States Army Europe (USAREUR) during the 1950s and 1960s. It served in North Africa and Italy in the Mediterranean Theater of Operations and France and Germany in the European Theater between 1942 and 1945.

The Royal Air Force (RAF) is the air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the First World War on 1 April 1918 through the merger of the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, they emerged as the largest air force in the world. Since its formation, they have played a significant role in British military history.

Hurricane Diane was the first Atlantic hurricane to cause more than an estimated $1 billion in damage, including direct costs and the loss of business and personal revenue. It formed on August 7 from a tropical wave between the Lesser Antilles and Cape Verde. Diane initially moved west-northwestward with little change in its intensity, but began to strengthen rapidly after turning to the north-northeast. On August 12, the hurricane reached peak sustained winds of 105 mph (165 km/h), making it a Category 2 hurricane. Gradually weakening after veering back west, Diane made landfall near Wilmington, North Carolina, as a strong tropical storm on August 17, just five days after Hurricane Connie struck near the same area. Diane weakened further after moving inland, at which point the United States Weather Bureau noted a decreased threat of further destruction. The storm turned to the northeast, and warm waters from the Atlantic Ocean helped produce record rainfall across the northeastern United States. On August 19, Diane emerged into the Atlantic Ocean southeast of New York City, becoming extratropical two days later and completely dissipating by August 23.

Israeli settlements, also called Israeli colonies, are the civilian communities built by Israel throughout the Israeli-occupied territories. They are populated by Israeli citizens, almost exclusively of Jewish identity or ethnicity, and have been constructed on lands that Israel has militarily occupied since the Six-Day War in 1967. The international community considers Israeli settlements to be illegal under international law, but Israel disputes this. In 2024, the International Court of Justice (ICJ) found in an advisory opinion that Israel's occupation was illegal and ruled that Israel had "an obligation to cease immediately all new settlement activities and to evacuate all settlers" from the occupied territories. The population of the settlements increased rapidly over the last 35 years. The expansion of settlements often involves the confiscation of Palestinian land and resources, leading to displacement of Palestinian communities and creating a source of tension and conflict. Settlements are often protected by the Israeli military and are frequently flashpoints for violence against Palestinians. Furthermore, the presence of settlements and Jewish-only bypass roads creates a fragmented Palestinian territory, seriously hindering economic development and freedom of movement for Palestinians.
