March 4 in History

The 50s decade ran from January 1, 50, to December 31, 59. It was the sixth decade in the Anno Domini/Common Era, if the nine-year period from 1 AD to 9 AD is considered as a "decade".

A martyr is someone who suffers persecution and death for advocating, renouncing, or refusing to renounce or advocate, a religious belief or other cause as demanded by an external party. In colloquial usage, the term can also refer to any person who suffers a significant consequence in protest or support of a cause.

Emperor Wen of Sui (隋文帝; 21 July 541 – 13 August 604), personal name Yang Jian (楊堅), childhood name Naluoyan (那羅延), Xianbei name Puliuru Jian (普六茹堅), was the founding emperor of the Sui dynasty of China. As a Buddhist, he encouraged the spread of Buddhism through the state. He is credited with reunifying China proper in 589, bringing an end to nearly three centuries of political fragmentation that began with the breakaway of the Cheng-Han and Han-Zhao regimes from the Western Jin in 304. His reign also saw the initiation of the Grand Canal, a major infrastructure project that would later facilitate the integration of northern and southern China. As a Northern Zhou official, Yang Jian served with apparent distinction during the reigns of the Emperor Wu and Emperor Xuan. When the erratic Emperor Xuan died in 580, Yang, as his father-in-law, seized power as regent. After defeating General Yuchi Jiong, who resisted him, he seized the throne for himself, establishing the new Sui dynasty. Yang Jian was the first ethnic Han ruler to control the entirety of North China after the Xianbei people conquered the region from the Liu Song dynasty (not counting the brief reconquest by Emperor Wu of Liang). Generally speaking, Emperor Wen's reign was a great period of prosperity, not seen since the Han dynasty. Economically, the nation prospered. It was said that there was enough food stored for 50 years. The military was also powerful. At the beginning of his reign, Sui faced the threat of the Göktürks in the north, neighbored Tibetan tribes in the west, Goguryeo in the northeast, and Champa (Linyi) in the south. By the end of Emperor Wen's reign, the Göktürks had split into an eastern and a western khaganate, the eastern one being nominally submissive to Sui, as was Goguryeo. Champa was defeated and, while not conquered, did not remain a threat.

A knyaz, also knez, knjaz, kniaź or kniaz, is a historical Slavic title, used both as a royal and noble title in different times. It is usually translated into English as 'prince', 'king' or 'duke', depending on specific historical context and the potentially known Latin equivalents at the time; the word was originally derived from the common Germanic *kuningaz ('king').

In religion, a relic is an object or article of religious significance from the past. It usually consists of the physical remains or personal effects of a saint or other person preserved for the purpose of veneration as a tangible memorial. Relics are an important aspect of some forms of Buddhism, Hinduism, Christianity, Islam, Shamanism, and many other religions. Relic derives from the Latin reliquiae, meaning "remains", and a form of the Latin verb relinquere, to "leave behind, or abandon". A reliquary is a shrine that houses one or more religious relics.

Frederick Barbarossa (December 1122 – 10 June 1190), also known as Frederick I (German: Friedrich; Italian: Federico), was the Holy Roman Emperor from 1155 until his death in 1190. He was elected King of Germany in Frankfurt on 4 March 1152 and crowned in Aachen on 9 March 1152. He was crowned King of Italy on 24 April 1155 in Pavia and emperor by Pope Adrian IV on 18 June 1155 in Rome. Two years later, the term sacrum ("holy") first appeared in a document in connection with his empire. He was later formally crowned King of Burgundy, at Arles on 30 June 1178. His nickname of Barbarossa (meaning "Red Beard" in Italian) "was first used by the Florentines only in 1298 to differentiate the emperor from his grandson, Frederick II ... and was never employed in medieval Germany" (the colour red was "also associated in the Middle Ages with malice and a hot temper"; in reality, Frederick's hair was "blond", although his beard was described by a contemporary as "reddish"). In German, he was known as Kaiser Rotbart, which in English means "Emperor Redbeard". The prevalence of the Italian nickname, even in later German usage, reflects the centrality of the Italian campaigns under his reign, and "remains to this day one of the [most] powerful historical monikers." Frederick was by inheritance Duke of Swabia (1147–1152, as Frederick III) before his imperial election in 1152. He was the son of Duke Frederick II of the Hohenstaufen dynasty and Judith, daughter of Henry IX, Duke of Bavaria, from the rival House of Welf. Frederick, therefore, descended from the two leading families in Germany, making him an acceptable choice for the Empire's prince-electors. Frederick joined the Third Crusade and opted to travel overland to the Holy Land. In 1190, Frederick drowned attempting to cross the Saleph River, leading to most of his army abandoning the Crusade before reaching Acre. Historians consider him among the Holy Roman Empire's greatest medieval emperors. He combined qualities that made him appear almost superhuman to his contemporaries: his longevity, his ambition, his extraordinary skills at organization, his battlefield acumen, and his political perspicacity. His contributions to Central European society and culture include the re-establishment of the Corpus Juris Civilis, or the Roman rule of law, which counterbalanced the papal power that had dominated the German states since the conclusion of the Investiture controversy. Due to his popularity and fame, in the 19th and early 20th centuries, he was used as a political symbol by many movements and regimes: the Risorgimento, the Wilhelmine government in Germany (especially under Emperor Wilhelm I), and the Nazi movement (Operation Barbarossa, Barbarossa decree) resulting in mixed legacies.

Alexios II Komnenos (Greek: Ἀλέξιος Κομνηνός, romanized: Aléxios Komnēnós; 14 September 1169 – September 1183), Latinized Alexius II Comnenus, was Byzantine emperor from 1180 to 1183. He ascended to the throne as a minor. For the duration of his short reign, the imperial power was de facto held by regents.

The Battle of the Sit River took place on 4 March 1238 between the Mongol forces of Batu Khan and the army of Vladimir-Suzdal led by Grand Prince Yuri II of Vladimir during the Mongol invasion of Kievan Rus'. The engagement occurred in the northern part of what is now the Sonkovsky District of Tver Oblast, near the selo of Bozhonka.

King U-thong (Thai: พระเจ้าอู่ทอง; pronounced [ʔùː.tʰɔ̄ːŋ]) or King Ramathibodi I (Thai: สมเด็จพระรามาธิบดีที่ ๑; Rāmādhipatī; , 1314–1369) was the founder and first monarch of the Ayutthaya Kingdom, reigning from 1351 to 1369. He is traditionally regarded as a pivotal figure in Thai history for unifying the rival power centers of Lopburi (Lavo) and Suphan Buri (Suphannaphum), establishing a centralized state that would dominate mainland Southeast Asia for over four centuries. Ramathibodi I was the son of a mixed Siamese Mon–Chinese monarch Baramaraja, previously a prince of Si Satchanalai who subsequently ascended the throne of Xiān's Ayodhya, and Sunandhadevī, a younger princess of the court of Suvarnaraja, the ninth monarch of Xiān. Originally known by the title Varashreṣṭhakumāra (วรเชษฐกุมาร), he succeeded his father as king of Xiān in 1344. In 1351, he was formally enthroned as the founding monarch of the Ayutthaya Kingdom. His maternal lineage can be traced back to the Dvaravati period, specifically under the ruling dynasty of the polity situated in the Phraek Si Racha region.

Jogaila (Lithuanian: [jɔˈɡâːɪɫɐ] ; c. 1352/1362 – 1 June 1434), later Władysław II Jagiełło (Polish: [vwaˈdɨswaf jaˈɡʲɛwwɔ] ), was Grand Duke of Lithuania beginning in 1377 and King of Poland from 1386 until his death. As Grand Duke, he ruled Lithuania from 1377 to 1381 and from 1382 to 1401, at which time he became the Supreme Duke of Lithuania in exchange for naming his cousin Vytautas as the new Grand Duke. Władysław II initially served as King of Poland alongside his wife Jadwiga until her death in 1399, and then the sole ruler until his own death in 1434. Raised a Lithuanian polytheist, he converted to Catholicism in 1386 and baptized as Ladislaus (Polish: Władysław) in Kraków, married the young Queen Jadwiga, and was crowned King of Poland as Władysław II Jagiełło. In 1387, he converted Lithuania to Catholicism. His sole reign in Poland started in 1399, upon the death of Queen Jadwiga, lasted a further thirty-five years, and laid the foundation for the centuries-long Polish–Lithuanian union. He was a member of the Jagiellonian dynasty in Poland that bears his name and was previously also known as the Gediminid dynasty in the Grand Duchy of Lithuania. The dynasty ruled both states until 1572, and became one of the most influential dynasties in late medieval and early modern Europe. Jogaila was the last pagan ruler of medieval Lithuania. After he became King of Poland, as a result of the Union of Krewo, the newly formed Polish-Lithuanian union confronted the growing power of the Teutonic Order. The allied victory at the Battle of Grunwald in 1410, followed by the Peace of Thorn, secured the Polish and Lithuanian borders and marked the emergence of the Polish–Lithuanian alliance as a significant force in Europe. The reign of Władysław II Jagiełło extended Polish frontiers and is often considered the beginning of Poland's Golden Age.

The Wars of the Roses, known at the time and in the following centuries as the Civil Wars, were a series of armed confrontations, machinations, battles and campaigns fought for control of the English throne from 1455 to 1487. The conflict was fought between supporters of the House of York and the House of Lancaster, two rival cadet branches of the royal House of Plantagenet. The conflict resulted in the end of Lancaster's male line in 1471, leaving the Tudor family to inherit, through the female line, the Lancaster claim to the throne. The conflict was largely brought to an end upon the union of the two houses through marriage, creating the Tudor dynasty that would subsequently rule England.

Christopher Columbus (; between 25 August and 31 October 1451 – 20 May 1506) was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish transatlantic voyages in the name of the Catholic Monarchs, opening the way for the widespread European exploration and colonization of the Americas. His expeditions were the first known European contact with the Caribbean and Central and South America. The name Christopher Columbus is the anglicization of the Latin Christophorus Columbus. Growing up on the coast of Liguria, he went to sea at a young age and traveled widely, as far north as the British and Irish Isles and as far south as what is now Ghana. He married Portuguese noblewoman Filipa Moniz Perestrelo, who bore a son, Diego, and was based in Lisbon for several years. He later took a Castilian mistress, Beatriz Enríquez de Arana, who bore a son, Ferdinand. Largely self-educated, Columbus was knowledgeable in geography, astronomy, and history. He developed a plan to seek a western sea passage to the East Indies, hoping to profit from the lucrative spice trade. After the Granada War, and Columbus's persistent lobbying in multiple kingdoms, the Catholic Monarchs, Queen Isabella I and King Ferdinand II, agreed to sponsor a journey west. Columbus left the Port of Palos in August 1492 with three ships and made landfall in the Americas on 12 October, ending the period of human habitation in the Americas now referred to as the pre-Columbian era. His landing place was an island in the Bahamas, known by its native inhabitants as Guanahani. He then visited the islands now known as Cuba and Hispaniola, establishing a colony in what is now Haiti. Columbus returned to Castile in early 1493, with captured natives. Word of his voyage soon spread throughout Europe. Columbus made three further voyages to the Americas, exploring the Lesser Antilles in 1493, Trinidad and the northern coast of South America in 1498, and the east coast of Central America in 1502. Many of the names given to geographical features by Columbus, particularly the names of islands, are still in use. He gave the name indios ('Indians') to the Indigenous peoples he encountered. The extent to which he was aware that the Americas were a wholly separate landmass is uncertain; he never clearly renounced his belief he had reached the Far East. As a colonial governor, Columbus was accused by some of his contemporaries of significant brutality and removed from the post. Columbus's strained relationship with the Crown of Castile and its colonial administrators in America led to his arrest and removal from Hispaniola in 1500, and later to protracted litigation over the privileges he and his heirs claimed were owed to them by the Crown. Columbus's expeditions inaugurated a period of exploration, conquest, and colonization that lasted for centuries, thus bringing the Americas into the European sphere of influence. The transfer of plants, animals, precious metals, culture, human populations, technology, diseases, and ideas between the Old World and New World that followed his first voyage are known as the Columbian exchange, named after him. These events and the effects which persist to the present are often cited as the beginning of the modern era. Diseases introduced from the Old World contributed to the genocide of Hispaniola's Indigenous peoples, who were also subject to enslavement and other mistreatments by Columbus's government. Increased public awareness of these interactions has led to Columbus being less celebrated in Western culture, which has historically idealized him as a heroic discoverer. Numerous places have been named for him.

Hernán Cortés, 1st Marquis of the Valley of Oaxaca (c. 1485 – 2 December 1547) was a Spanish conquistador, military commander, explorer, captain general, and writer who led an expedition that caused the fall of the Aztec Empire and brought large portions of what is now mainland Mexico under the rule of the King of Castile in the early 16th century. Cortés was part of the generation of Spanish explorers and conquistadors who began the first phase of the Spanish colonization of the Americas. Born in Medellín, Spain, to a family of lesser nobility, Cortés chose to pursue adventure and riches in the New World. He went to Hispaniola and later to Cuba, where he received an encomienda (the right to the labour of certain subjects). For a short time, he served as alcalde (magistrate) of the second Spanish town founded on the island. In 1519, he was elected captain of the third expedition to the mainland, which he partly funded. His enmity with the governor of Cuba, Diego Velázquez de Cuéllar, resulted in the recall of the expedition at the last moment, an order which Cortés ignored. Arriving on the continent, Cortés executed a successful strategy of allying with some indigenous people against others. He also used a native woman, Doña Marina, as an interpreter. She later gave birth to his first son. When the governor of Cuba sent emissaries to arrest Cortés, he fought them and won, using the extra troops as reinforcements. Cortés wrote letters directly to the king asking to be acknowledged for his successes instead of being punished for mutiny. After he overthrew the Aztec Empire, Cortés was awarded the title of marqués del Valle de Oaxaca, while the more prestigious title of viceroy was given to a high-ranking nobleman, Antonio de Mendoza. In 1541, Cortés returned to Spain, where he died six years later of natural causes.

The Massachusetts Bay Colony (1628–1691), more formally the Colony of Massachusetts Bay, was an English settlement on the east coast of North America around Massachusetts Bay, a territory inhabited by Algonquian Native American tribes. The colony was in a territory the colonists called New England, with initial settlements on two natural harbors and surrounding land about 15.4 miles (24.8 km) apart—the areas around Salem and Boston, north of the previously established Plymouth Colony. The territory nominally administered by the Massachusetts Bay Colony covered much of central New England, including portions of what are now Massachusetts, Maine, New Hampshire, and Connecticut. The territory of the Massachusetts Bay colony was one of the several colonial territories reorganized as the Province of Massachusetts Bay in 1691. The Massachusetts Bay Colony was founded by the owners of the Massachusetts Bay Company—a joint-stock company established by English royal charter. The company included investors in the failed Dorchester Company, which had established a short-lived settlement on Cape Ann in 1623; the Massachusetts Bay Colony was therefore a second attempt at colonization five years later. It was successful, with about 20,000 people migrating to New England in the 1630s. The population was Puritan and was governed largely by a small group of leaders strongly influenced by Puritan teachings. It was the first slave-holding colony in New England, and its governors were elected by an electorate limited to freemen who had been formally admitted to the local church. As a consequence, the colonial leadership showed little tolerance for other religious views, including Anglican, Quaker, and Baptist theologies. The colonists maintained relations with the Massachusett and other Algonquians of the Northeastern Woodlands and sought to convert them to Christianity; however, they did join their neighbor colonies in the Pequot War (1636–1638) and King Philip's War (1675–1678). After that, most of the tribes of southern New England made peace treaties with the colonists or were sold into slavery after King Philip's War (apart from the Pequot tribe, whose survivors were largely absorbed into the Narragansett and Mohegan tribes following the Pequot War). The Massachusetts Bay Colony was economically successful, trading with England, Mexico, and the West Indies. In addition to barter, transactions were done in English pounds, Spanish "pieces of eight", and wampum in the 1640s. In 1652, a currency shortage prompted the colony to authorize silversmith John Hull to issue coinage, now known as the oak tree, willow tree, and pine tree shillings. Political differences with England after the English Restoration led to the forced separation of the northern county as the Province of New Hampshire in 1680 and the revocation of the colonial charter in 1684. King James II established the Dominion of New England in 1686 to bring all of the New England colonies under firmer crown control. The Dominion collapsed after the Glorious Revolution of 1688 deposed James, and the Massachusetts Bay Colony reverted to rule under its revoked charter until 1691, when a new charter was issued for the Province of Massachusetts Bay. This new province combined the Massachusetts Bay territories with those of the Plymouth Colony and proprietary holdings on Nantucket and Martha's Vineyard. Sir William Phips arrived in 1692 bearing the charter and formally took charge of the new province, when the colony, beginning in Salem Village, was coming to grips with the witch trials crises.

Charles II was King of Scotland from 1649 until 1651 and King of England, Scotland, and Ireland from the 1660 Restoration of the monarchy until his death in 1685.

John Flamsteed (19 August 1646 – 31 December 1719) was an English astronomer and the first Astronomer Royal. His main achievements were the preparation of a 3,000-star catalogue, Catalogus Britannicus, and a star atlas called Atlas Coelestis, both published posthumously. He also made the first recorded observations of Uranus, although he mistakenly catalogued it as a star, and he laid the foundation stone for the Royal Greenwich Observatory.

William Penn (24 October [O.S. 14 October] 1644 – 10 August [O.S. 30 July] 1718) was an English writer, theologian, religious thinker, and influential Quaker who founded the Province of Pennsylvania. An advocate of democracy and religious freedom, Penn was known for his amicable relations and successful treaties with the Lenape native peoples who had resided in present-day Pennsylvania before European colonisation there. Penn was expelled from the University of Oxford in 1662 for his religious nonconformity. That early break with institutional authority became central to his life. He embraced Quakerism, defended freedom of conscience, and repeatedly challenged the established Church of England’s restrictions on religious dissent. Penn built a remarkable life outside conventional institutions, combining religious leadership, writing, political advocacy, and practical enterprise. Today, his legacy is commemorated at Christ Church, Oxford, where his portrait is displayed in the dining hall. His most important undertaking was Pennsylvania. In 1681, King Charles II granted Penn an area of land corresponding to the present-day U.S. states of Pennsylvania and Delaware to offset debts he owed to Penn’s father, the admiral and politician Sir William Penn. Penn developed the land as a territory grounded in Quaker ideals of peace and equality alongside economic opportunity and representative government. The following year, Penn left England and sailed up Delaware Bay and the Delaware River, where he founded Philadelphia on the river's western bank. Penn's Quaker government was not viewed favorably by the Dutch, Swedish and English settlers in what is now Delaware, and the land was also claimed by the Calverts, proprietors of the neighbouring Province of Maryland. In 1704, the three southernmost counties of the province of Pennsylvania were granted permission to form a new, semi-autonomous Delaware Colony. As one of the earliest supporters of colonial unification, Penn wrote and urged the union of all the British colonies into what would later become the United States. The democratic principles that he included in the West Jersey Concessions and outlined in the Pennsylvania Frame of Government inspired delegates to the 1787 Constitutional Convention in Philadelphia when they came to write the Constitution of the United States. A man of deep religious conviction, Penn authored numerous works, exhorting believers to adhere to the spirit of Primitive Christianity. Penn was imprisoned several times in the Tower of London due to his faith. His book No Cross, No Crown, published in 1669 while he was in jail, has become a classic of Christian theological literature.

The Order of Preachers, commonly known as the Dominican Order, is a Catholic mendicant order of pontifical right that was founded in France by the Castilian priest Dominic de Guzmán. It was approved by Pope Honorius III via the papal bull Religiosam vitam on 22 December 1216. Members of the order, who are referred to as Dominicans, generally display the letters OP after their names, standing for Ordo Praedicatorum, meaning of "the Order of Preachers". Membership in the order includes friars, nuns, active sisters, and lay or secular Dominicans, formerly known as tertiaries. More recently, there have been a growing number of associates of the religious sisters who are unrelated to the tertiaries.

Wolfgang Amadeus Mozart (27 January 1756 – 5 December 1791) was a Classical composer and musician. He completed more than 800 works in his life—including outstanding examples of most of the genres of his time: symphonies, concertos, chamber music, opera and choral music—and is regarded as one of the greatest composers in the history of Western music. Born in Salzburg, Mozart quickly emerged as a child prodigy under the training of his father Leopold, a skilled pedagogue. At the age of five he was already competent on keyboard and violin, had begun to compose, and had performed before European royalty. His father took him on a grand tour of Europe and then three trips to Italy. At 17 he was a musician at the Salzburg court but grew restless and travelled in search of a better position. A fruitless journey in search of employment (1777–1779) led him to Paris, Mannheim, Munich and eventually back to Salzburg. During this time he wrote his five violin concertos, the Sinfonia Concertante, various masses and the opera Idomeneo. While he was visiting Vienna in 1781, Mozart's quarrels with his Salzburg employers came to a head and he was dismissed. He chose to remain in Vienna, where he stayed for the rest of his life, achieving fame and some financial success, but no long-term security. During Mozart's early years in Vienna he produced several notable works, such as the opera Die Entführung aus dem Serail, the Great Mass in C minor, the "Haydn" Quartets and a number of symphonies. Throughout his Vienna years Mozart composed more than a dozen piano concertos, many considered some of his greatest achievements. In the final years of his life, he wrote many of his best-known works, including his last three symphonies, culminating in the Jupiter, the serenade Eine kleine Nachtmusik, his Clarinet Concerto, the operas Le nozze di Figaro, Don Giovanni, Così fan tutte and Die Zauberflöte, the Piano Concerto No. 27 and his Requiem. The Requiem was largely unfinished at the time of his death at the age of 35.

The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence or simply the American Revolution, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and, commanded by George Washington, defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war. In 1783, in the Treaty of Paris, the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation. In 1763, after the British Empire gained dominance in North America following its victory over the French in the Seven Years' War, tensions and disputes began escalating between the British and the Thirteen Colonies, especially following passage of the Stamp and Townshend Acts. The British Army responded by seeking to occupy Boston militarily, leading to the Boston Massacre on March 5, 1770. In mid-1774, with tensions escalating even further between the British Army and the colonies, the British Parliament imposed the Intolerable Acts, an attempt to disarm Americans, leading to the Battles of Lexington and Concord in April 1775, the first battles of the Revolutionary War. In June 1775, the Second Continental Congress voted to incorporate colonial-based Patriot militias into a central military, the Continental Army, and unanimously appointed Washington its commander-in-chief. Two months later, in August 1775, George III declared the colonies to be in a state of rebellion. In July 1776, the Second Continental Congress formalized the war, passing the Lee Resolution on July 2, and, two days later, unanimously adopting the Declaration of Independence, on July 4. In March 1776, in an early win for the newly-formed Continental Army under Washington's command, following a successful siege of Boston, the Continental Army successfully drove the British Army out of Boston. British commander in chief William Howe responded by launching the New York and New Jersey campaign, which resulted in Howe's capture of New York City in November. Washington responded by clandestinely crossing the Delaware River and winning small but significant victories at Trenton and Princeton. In the summer of 1777, as Howe was poised to capture Philadelphia, the Continental Congress fled to Baltimore. In October 1777, a separate northern British force under the command of John Burgoyne was forced to surrender at Saratoga in an American victory that proved crucial in convincing France and Spain that an independent United States was a viable possibility. France signed a commercial agreement with the revolutionaries, followed by a Treaty of Alliance in February 1778. In 1779, the Sullivan Expedition undertook a scorched earth campaign against British-allied factions of the Haudenosaunee Confederacy (also Iroquois). Native American raids on the American frontier, however, continued to be a problem. Also, in 1779, Spain allied with France against Great Britain in the Treaty of Aranjuez, though Spain did not formally ally with the Americans. Howe's replacement Henry Clinton intended to take the war against the Americans into the Southern Colonies. Despite some initial success, British General Cornwallis was besieged by a Franco-American army in Yorktown, Virginia, in September and October 1781. The French navy cut off Cornwallis's escape and he was forced to surrender in October. The British wars with France and Spain continued for another two years, but fighting largely ceased in North America. In the Treaty of Paris, signed on September 3, 1783, Great Britain acknowledged the sovereignty and independence of the United States, bringing the American Revolutionary War to an end. The Treaties of Versailles resolved Great Britain's conflicts with France and Spain, and forced Great Britain to cede Tobago, Senegal, and small territories in India to France, and Menorca, West Florida, and East Florida to Spain.

The 1st United States Congress, comprising the United States Senate and the United States House of Representatives, met from March 4, 1789, to March 4, 1791, during the first two years of George Washington's presidency, first at Federal Hall in New York City and later at Congress Hall in Philadelphia. With the initial meeting of the First Congress, the United States federal government officially began operations under the new (and current) frame of government established by the 1787 Constitution. The apportionment of seats in the House of Representatives was based on the provisions of Article I, Section 2, Clause 3, of the Constitution. Both chambers had a Pro-Administration majority. Twelve articles of amendment to the Constitution were passed by this Congress and sent to the states for ratification; the ten ratified as additions to the Constitution on December 15, 1791, are collectively known as the Bill of Rights, with an additional amendment ratified more than two centuries later to become the Twenty-seventh Amendment to the United States Constitution.

In the administrative divisions of France, the department is one of the three levels of government under the national level, between the administrative regions and the communes. There are a total of 101 departments, consisting of ninety-six departments in metropolitan France, and five overseas departments, which are also classified as overseas regions. Departments are further subdivided into 333 arrondissements and 2,054 cantons. These last two levels of government have no political autonomy, instead serving as the administrative basis for the local organisation of police, fire departments, and, in certain cases, elections.

Vermont ( ) is a landlocked state in the New England region of the Northeastern United States. It borders Massachusetts to the south, New Hampshire to the east, New York to the west, and the Canadian province of Quebec to the north. According to the most recent U.S. census estimates, the state has an estimated population of 644,663, making it the second-least populated of all U.S. states. It is the nation's sixth-smallest state by total area. The state's capital, Montpelier, is the least populous U.S. state capital. No other U.S. state has a most populous city with fewer residents than Vermont's most populous city, Burlington. Native Americans have inhabited the area for about 12,000 years. The competitive tribes of the Algonquian-speaking Abenaki and Iroquoian-speaking Mohawk were active in the area at the time of European encounter. During the 17th century, French colonists claimed the territory as part of New France. Conflict arose when the Kingdom of Great Britain began to settle colonies to the south along the Atlantic coast; France was defeated in 1763 in the Seven Years' War, ceding its territory east of the Mississippi River to Britain. Thereafter, the nearby British Thirteen Colonies disputed the extent of the area called the New Hampshire Grants to the west of the Connecticut River, encompassing present-day Vermont. The provincial government of New York sold land grants to settlers in the region, which conflicted with earlier grants from the government of New Hampshire. The Green Mountain Boys militia protected the interests of the established New Hampshire land grant settlers. Ultimately, a group of settlers with New Hampshire land grant titles established the Vermont Republic in 1777 as an independent state during the American Revolutionary War. The Vermont Republic abolished slavery before any other U.S. state. It was admitted to the Union in 1791 as the 14th state. The geography of the state is marked by the Green Mountains, which run north–south up the middle of the state, separating Lake Champlain and other valley terrain on the west from the Connecticut River Valley that defines much of its eastern border. A majority of its terrain is forested with hardwoods and conifers. The state has warm, humid summers and cold, snowy winters. Vermont's economic activity of $40.6 billion in 2022 is ranked last on the list of U.S. states and territories by GDP, but 21st in GDP per capita. Known for its progressivism, the state was one of the first in the U.S. to recognize same-sex civil unions and marriage, has the highest proportion of renewable electricity generation at 99.9%, and is one of the least religious and least racially/ethnically diverse states. Dairy, forestry, maple syrup, and wine are important sectors in Vermont's agricultural economy. Vermont produces approximately 50% of the nation's maple syrup.

The Eleventh Amendment (Amendment XI) is an amendment to the United States Constitution which was passed by Congress on March 4, 1794, and ratified by the states on February 7, 1795. The Eleventh Amendment restricts the ability of individuals to bring suit against states of which they are not citizens in federal court. The Eleventh Amendment was adopted to overrule the Supreme Court's decision in Chisholm v. Georgia (1793). In that case, the Court held that states did not enjoy sovereign immunity from suits made by citizens of other states in federal court. Although the Eleventh Amendment established that federal courts do not have the authority to hear cases brought by private parties against a state of which they are not citizens, the Supreme Court has ruled the amendment applies to all federal suits against states brought by private parties. The Supreme Court has also held that Congress can abrogate state sovereign immunity when using its authority under Section 5 of the Fourteenth Amendment. Other recent cases (Torres v. Texas Department of Public Safety, Central Virginia Community College v. Katz, PennEast Pipeline Co. v. New Jersey) have identified further exceptions to the general sovereign immunity of states when Congress acts pursuant to its Article I powers, which have alternatively been referred to as "waivers in the plan of the Convention". The Supreme Court has also held that federal courts can enjoin state officials from violating federal law.

John Adams (October 30, 1735 – July 4, 1826) was a Founding Father and the second president of the United States from 1797 to 1801. Before his presidency, he was a leader of the American Revolution that achieved independence from Great Britain. During the latter part of the Revolutionary War and in the early years of the new nation, he served the Continental Congress of the United States as a senior diplomat in Europe. Adams was the first vice president of the United States, serving from 1789 to 1797. He was a dedicated diarist and regularly corresponded with contemporaries, including his wife and advisor Abigail Adams and his friend and rival Thomas Jefferson. A lawyer and political activist prior to the Revolution, Adams was devoted to the right to counsel and presumption of innocence. He defied anti-British sentiment and successfully defended British soldiers against murder charges arising from the Boston Massacre. Adams was a Massachusetts delegate to the Continental Congress and became a leader of the revolution. He assisted Jefferson in drafting the Declaration of Independence in 1776 and was its primary advocate in Congress. As a diplomat, he represented the United States in France and the Netherlands during the war. He helped negotiate the peace treaty with Great Britain, secured Dutch loans for the American government, and was the first United States ambassador to Great Britain. Adams was the primary author of the Massachusetts Constitution in 1780, which, with his other political writings, influenced the United States Constitution. Adams was elected to two terms as vice president under President George Washington and was elected as the United States' second president in 1796 under the banner of the Federalist Party. Adams's term was dominated by the issue of the French Revolutionary Wars, and his insistence on American neutrality led to fierce criticism from both the Jeffersonian Republicans and from some in his own party, led by his rival Alexander Hamilton. Adams signed the controversial Alien and Sedition Acts and built up the Army and Navy in an undeclared naval war with France. He was the first president to reside in the White House. In his 1800 bid for reelection to the presidency, opposition from Federalists and accusations of despotism from Jeffersonians led to Adams losing to his vice president and former friend, Thomas Jefferson. After his defeat, he retired to Massachusetts. He eventually resumed his friendship with Jefferson by initiating a continuing correspondence. John Adams died on July 4, 1826 – the fiftieth anniversary of the adoption of the Declaration of Independence. The Adams political family included his son John Quincy Adams, the sixth president. Adams and his son are the only presidents of the first twelve who never owned slaves. Most historians have favorably ranked his administration.

The Castle Hill convict rebellion (also known as Battle of Vinegar Hill) was a convict rebellion in Castle Hill, Sydney, then part of the British colony of New South Wales. Led by veterans of the Irish Rebellion of 1798, the poorly armed insurgents confronted the colonial forces of Australia on 5 March 1804 at Rouse Hill. Their rout in the resulting skirmish was hailed by loyalists as "Australia's Vinegar Hill" after the 1798 battle of Vinegar Hill, where Society of United Irishmen rebels were decisively defeated. The incident was the first major convict uprising in Australian history to be suppressed under martial law. On 4 March 1804, 233 convicts, led by Philip Cunningham, a veteran of the Irish Rebellion of 1798 as well as a mutineer on the convict transport Anne, escaped from a prison farm, intent on "capturing ships to sail to Ireland". In response, martial law was quickly declared in the colony. The mostly Irish rebels, having gathered reinforcements, were pursued by colonial forces under George Johnston until they were caught on Rouse Hill on 5 March 1804. While negotiating under a flag of truce, Cunningham was arrested. Johnston's troops then charged and scattered the rebels, and the rebellion was suppressed. Nine of the rebel leaders were executed, and hundreds were punished, before martial law was revoked a week after the battle.

Charles Albert (Italian: Carlo Alberto I; 2 October 1798 – 28 July 1849) was the King of Sardinia and ruler of the Savoyard state from 27 April 1831 until his abdication in 1849. His name is bound up with the first Italian constitution, the Statuto Albertino, and with the First Italian War of Independence (1848–1849). During the Napoleonic period, Charles Albert resided in France, where he received a liberal education. As Prince of Carignano in 1821, he granted and then withdrew his support for a rebellion which sought to force Victor Emmanuel I to institute a constitutional monarchy. He became a conservative and participated in the legitimist expedition against the Spanish liberals in 1823 known as the "Hundred Thousand Sons of Saint Louis". Charles Albert became king of Sardinia in 1831 on the death of his distant cousin Charles Felix, who had no heir. As king, after an initial conservative period during which he supported various European legitimist movements, he adopted the neo-Guelph idea of a federal Italy, led by the Pope and freed from the House of Habsburg in 1848. In the same year, he granted the Albertine Statute, the first Italian constitution, which remained in force until 1947. Charles Albert led his forces against the Imperial Austrian army in the First Italian War of Independence but was abandoned by Pope Pius IX and Ferdinand II of the Two Sicilies, and was defeated in 1849 at the Battle of Novara, after which he abdicated in favour of his son, Victor Emmanuel II. Charles Albert died in exile a few months later in the Portuguese city of Porto. The attempt to free northern Italy from Austria represents the first attempt of the House of Savoy to alter the equilibrium established in the Italian peninsula after the Congress of Vienna. These efforts were continued successfully by his son Victor Emmanuel II, who became the first king of a unified Italy in 1861. Charles Albert received several nicknames including "the Italian Hamlet" (given to him by Giosuè Carducci on account of his gloomy, hesitant, and enigmatic character), as well as "the Hesitant King" (Re Tentenna) because he hesitated for a long time between the establishment of a constitutional monarchy and the reinforcement of absolute rule.

Zachary Taylor was the 12th president of the United States, serving from 1849 until his death in 1850.

As a result, he won election to the White House despite his vague political beliefs. His top priority as president was to preserve the Union. He died 16 months into his term from a stomach disease. Taylor had the third-shortest presidential term in U.S. history.

The flags of the Confederate States of America have a history of three successive designs during the American Civil War. The flags were known as the "Stars and Bars", used from 1861 to 1863; the "Stainless Banner", used from 1863 to 1865; and the "Blood-Stained Banner", used in 1865 shortly before the Confederacy's dissolution. A rejected national flag design was also used as a battle flag by the Confederate Army and featured in the "Stainless Banner" and "Blood-Stained Banner" designs. Although this design was never a national flag, it is the most commonly-recognized symbol of the Confederacy.

Johnson was a War Democrat who ran with Lincoln on the National Union Party ticket in the 1864 presidential election, coming to office as the American Civil War concluded. Johnson favored quick restoration of the seceded states to the Union without protection for the newly freed people who were formerly enslaved, as well as pardoning ex-Confederates. This led to conflict with the Republican Party-dominated U.S. Congress, culminating in his impeachment by the House of Representatives in 1868. He was acquitted in the Senate by one vote.

The Saimaa ringed seal is a species of seal. It is among the most endangered seals in the world, having a total population of only about 500 individuals. The only existing population of these seals is found in Lake Saimaa, Finland. It has lived in complete isolation from other ringed seal populations for around 9,500 years, and have diverged into a morphologically and ecologically different species or subspecies.

Basketball is a team sport in which two teams of five players each oppose one another on a rectangular court. Players compete with the primary objective of shooting a basketball through a hoop at each end of the court. Teams alternate between offense, and defense. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the fouled team either takes one to three free throws worth one point each, or restarts play with an inbound pass. The team with the most points at the end of the game wins. If regulation play expires with the score tied, most basketball leagues mandate additional periods of play (overtime) until the score is no longer tied.
