Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. Their number varies according to the approximately 11-year solar cycle.

Nobility is a social class found in many societies that have an aristocracy. It is normally appointed by and ranked immediately below royalty. Nobility has often been an estate of the realm with many exclusive functions and characteristics. The characteristics associated with nobility may constitute substantial advantages over or relative to non-nobles or simply formal functions, and vary by country and by era. Membership in the nobility, including rights and responsibilities, is typically hereditary and patrilineal.

Öljeyitü Khan (Mongolian: Өлзийт Хаан; Mongolian script: ᠥᠯᠵᠡᠶᠢᠲᠦ Öljeyitü; Chinese: 完澤篤汗), born Temür (Mongolian: Төмөр ᠲᠡᠮᠦᠷ; Chinese: 鐵穆耳; 15 October 1265 – 10 February 1307), also known by his temple name as the Emperor Chengzong of Yuan (Chinese: 元成宗; pinyin: Yuán Chéngzōng; Wade–Giles: Yüan2 Ch'eng2-tsung1), was the second emperor of the Yuan dynasty of China, ruling from 10 May 1294 to 10 February 1307. Apart from being the Emperor of China, he is considered as the sixth Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire. He was an able ruler of the Yuan dynasty, and his reign established the patterns of power for the next few decades. Temür was the third son of the Crown Prince Zhenjin and a grandson of the Yuan dynasty founder Kublai Khan. During his rule, he achieved the nominal suzerainty of all Mongol states of the time. He showed respect for Confucianism, and called off invasions of Burma, Đại Việt, and Japan. His reign was beset by corruption and administrative inefficiencies.

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

Christopher Columbus 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.

Jacques Cartier (Breton: Jakez Karter; 31 December 1491 – 1 September 1557) was a French maritime explorer from Brittany. Jacques Cartier was the first European to describe and map the Gulf of Saint Lawrence and the shores of the Saint Lawrence River, which he named "Canada" after the Iroquoian names for the two big settlements he saw at Stadacona (Quebec City) and at Hochelaga (Montreal Island). Jacques Cartier, author of now-lost maps and accounts of his voyages, was the first European to describe and name this region and its inhabitants—at a time when the Spanish had already settled in the Caribbean, Mexico, and Central America, and were beginning their conquest of Peru.

Elizabeth I was Queen of England and Ireland from 17 November 1558 until her death in 1603. She was the last and longest reigning monarch of the House of Tudor. Her eventful reign, and its effect on history and culture, gave name to the Elizabethan era.

King Narai the Great (Thai: สมเด็จพระนารายณ์มหาราช, RTGS: Somdet Phra Narai Maharat, pronounced [sǒm.dèt pʰráʔ nāː.rāːj mā.hǎː.râːt] ), or Ramathibodi III (Thai: รามาธิบดีที่ ๓ ), was the 27th monarch of Ayutthaya Kingdom, the 4th and last monarch of the Prasat Thong dynasty. He was the king of Ayutthaya Kingdom from 1656 to 1688 and arguably the most famous king of the Prasat Thong dynasty. His reign was the most prosperous during the Ayutthaya period and saw the great commercial and diplomatic activities with foreign nations including the Middle East and the West. During the later years of his reign, Narai gave his favorite – the Greek adventurer Constantine Phaulkon – so much power that Phaulkon technically became the chancellor of the state. Through the arrangements of Phaulkon, the Siamese kingdom came into close diplomatic relations with the court of Louis XIV and French soldiers and missionaries filled the Siamese aristocracy and defense. The dominance of French officials led to frictions between them and the native mandarins and led to the turbulent revolution of 1688 towards the end of his reign. Narai's reign was also known for the 1662–1664 invasion of Burma, the destruction of the briefly independent port city of the Sultanate of Singgora (1605–1680), and the conflict he had with the English East India Company. The presence of numerous foreigners from the French Jesuits to the Persian delegates has left historians with rich sources of material on the city of Ayutthaya and its conflicts and courtly life in the seventeenth century that otherwise would not have survived the complete destruction of the capital in 1767.

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.

John Wilkes (17 October 1725 – 26 December 1797) was a British radical, journalist, politician, magistrate and writer. He was first elected a Member of Parliament in 1757. In the Middlesex election dispute, he fought for the right of his voters – rather than the House of Commons – to determine their representatives. In 1768, angry protests of his supporters were suppressed in the Massacre of St George's Fields. In 1771, he was instrumental in obliging the government to concede the right of printers to publish verbatim accounts of parliamentary debates. In 1776, he introduced the first bill for parliamentary reform in the British Parliament. During the American War of Independence, Wilkes was a supporter of the Patriots, who in turned admired his beliefs and support for their cause. In 1780 he commanded militia forces which helped put down the Gordon Riots, damaging his popularity with many British radicals. This marked a turning point, leading him to embrace increasingly conservative policies which caused dissatisfaction among the radical low- to middle-income landowners. This was instrumental in the loss of his Middlesex parliamentary seat in the 1790 general election. At the age of 65, Wilkes retired from politics and took no part in the social reforms following the French Revolution, such as Catholic emancipation in the 1790s. During his life, he earned a reputation as a libertine.

The Parliament of Great Britain was formed in May 1707 following the ratification of the Acts of Union by both the Parliament of England and the Parliament of Scotland. The Acts ratified the treaty of Union which created a new unified Kingdom of Great Britain and created the parliament of Great Britain located in the former home of the English parliament in the Palace of Westminster, near the City of London. This lasted nearly a century, until the Acts of Union 1800 merged the separate British and Irish Parliaments into a single Parliament of the United Kingdom with effect from 1 January 1801.

Louis XVI (Louis-Auguste; French: [lwi sɛːz]; 23 August 1754 – 21 January 1793) was the last king of France before the fall of the monarchy during the French Revolution. The son of Louis, Dauphin of France (son and heir apparent of King Louis XV), and Maria Josepha of Saxony, Louis became the new Dauphin when his father died in 1765. In 1770, he married Marie Antoinette. He became King of France and Navarre on his paternal grandfather's death on 10 May 1774, and reigned until the abolition of the monarchy on 21 September 1792. From 1791 onwards, he used the style of king of the French. The first part of Louis XVI's reign was marked by attempts to reform the French government in accordance with Enlightenment ideas. These included efforts to increase tolerance toward non-Catholics as well as abolishing the death penalty for deserters. The French nobility reacted to the proposed reforms with hostility, and successfully opposed their implementation. Louis implemented deregulation of the grain market, advocated by his economic liberal minister Turgot, but it resulted in an increase in bread prices. In periods of bad harvests, it led to food scarcity which, during a particularly bad harvest in 1775, prompted the masses to revolt. From 1776, Louis XVI actively supported the North American colonists, who were seeking their independence from Great Britain, which was realised in the Treaty of Paris (1783). The ensuing debt and financial crisis contributed to the unpopularity of the ancien régime. This led to the convening of the Estates General of 1789. Discontent among France's middle and lower classes intensified opposition to the French aristocracy and the absolute monarchy led by Louis XVI and his wife, Marie Antoinette. Tensions progressively rose, punctuated by violent riots such as the storming of the Bastille, which forced Louis to recognize the legislative authority of the National Assembly. Louis's indecisiveness and conservatism toward the demands of the Estates led many to despise him as the embodiment of ancien régime tyranny, and his popularity deteriorated progressively. His unsuccessful flight to Varennes in June 1791 seemed to confirm suspicions that the king hoped for foreign intervention to restore his power, deeply undermining his legitimacy. Four months later, the constitutional monarchy was declared, and the replacement of the monarchy with a republic became an ever-increasing possibility. The growth of anti-clericalism among revolutionaries resulted in the abolition of the dîme (religious land tax) and several government policies aimed at the dechristianization of France. With the outbreak of civil and international war, Louis XVI was arrested during the Insurrection of 10 August 1792. One month later, the monarchy was abolished and the French First Republic was proclaimed on 21 September 1792. The former king became a desacralized French citizen, addressed as Citoyen (Citizen) Louis Capet in reference to his ancestor Hugh Capet. Louis was tried by the National Convention (self-instituted as a tribunal for the occasion), found guilty of high treason, and executed by guillotine on 21 January 1793. Louis XVI's death brought an end to more than a thousand years of continuous French monarchy. Both of his sons died in childhood, before the Bourbon Restoration; his only child to reach adulthood, Marie Thérèse, was released to her Austrian relatives in exchange for French prisoners of war, eventually dying childless in 1851.

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 Second Continental Congress (1775–1781) was the meeting of delegates from the Thirteen Colonies that united in support of the American Revolution and Revolutionary War, which established American independence from Great Britain. The Congress constituted a new federation that it first named the United Colonies of North America, and in 1776, renamed the United States of America. The Congress began convening in present-day Independence Hall in Philadelphia, on May 10, 1775, with representatives from 12 of the 13 colonies, following the Battles of Lexington and Concord, the first battles of the Revolutionary War, which were fought on April 19, 1775. The Second Continental Congress succeeded the First Continental Congress, which met from September 5 to October 26, 1774, also in Philadelphia. The Second Congress functioned as the de facto federation government at the outset of the Revolutionary War by raising militias, directing strategy, appointing diplomats, and writing petitions such as the Declaration of the Causes and Necessity of Taking Up Arms and the Olive Branch Petition. All 13 colonies were represented by the time the Congress adopted the Lee Resolution, which declared independence from Great Britain on July 2, 1776, and the Congress unanimously agreed to the Declaration of Independence two days later. Congress functioned as the provisional government of the United States of America through March 1, 1781, when congress became what is now often called the Confederation Congress. During this period, it successfully managed the war effort, drafted the Articles of Confederation and Perpetual Union, adopted the first U.S. constitution, secured diplomatic recognition and support from foreign nations, and resolved state land claims west of the Appalachian Mountains. Many of the delegates who attended the Second Congress had also attended the First. They again elected Peyton Randolph as president of the Congress and Charles Thomson as secretary. Notable new arrivals included Benjamin Franklin of Pennsylvania and John Hancock of Massachusetts. Within two weeks, Randolph was summoned back to Virginia to preside over the House of Burgesses; Hancock succeeded him as president, and Thomas Jefferson replaced Randolph in the Virginia delegation. The number of participating colonies also grew, as Georgia endorsed the Congress in July 1775 and adopted the continental ban on trade with Britain.

The War of the First Coalition was a set of wars between a coalition of several European powers and France fought from 1792 to 1797. The coalition was only loosely allied and fought without much coordination; each power wanted to annex a different part of France should they defeat the French, something that never occurred.

The First Barbary War (1801–1805), also known as the Tripolitan War and the Barbary Coast War, was a conflict during the 1801–1815 Barbary Wars, in which the United States fought against Ottoman Tripolitania. Tripolitania had declared war against the United States over disputes regarding tributary payments in exchange for a cessation of Tripolitanian commerce raiding at sea. United States president Thomas Jefferson refused to pay this tribute. The First Barbary War was the first major American war fought outside the New World, and in the Arab world, besides the American–Algerian War (1785–1795).

The National Gallery is an art museum in Trafalgar Square in the City of Westminster, in Central London, England. Founded in 1824, it houses a collection of more than 2,300 paintings dating from the mid-13th century to 1900. The current director of the National Gallery is Gabriele Finaldi. The National Gallery is an exempt charity, and a non-departmental public body of the Department for Culture, Media and Sport. Its collection is held in trust by the charity on behalf of the British public, and entry to the main collection is free of charge. Unlike comparable museums in continental Europe, the National Gallery was not formed by nationalising an existing royal or princely art collection. It came into being when the British government bought 38 paintings from the heirs of John Julius Angerstein in 1824. After that initial purchase, the gallery was shaped mainly by its early directors, especially Charles Lock Eastlake, and by private donations, which now account for two-thirds of the collection. The collection is smaller than many European national galleries, but encyclopaedic in scope; most major developments in Western painting "from Giotto to Cézanne" are represented with important works. It used to be claimed that this was one of the few national galleries that had all its works on permanent exhibition, but this is no longer the case. The present building, the third site to house the National Gallery, was designed by William Wilkins. Building began in 1832 and it opened to the public in 1838. Only the façade onto Trafalgar Square remains essentially unchanged from this time, as the building has been expanded piecemeal throughout its history. Wilkins's building was often criticised for the perceived weaknesses of its design and for its lack of space; the latter problem led to the establishment of the Tate Gallery for British art in 1897. The Sainsbury Wing, a 1991 extension to the west by Robert Venturi and Denise Scott Brown, is a significant example of Postmodernist architecture in Britain.

The Lê Văn Khôi revolt (Vietnamese: Cuộc nổi dậy Lê Văn Khôi, 1833–1835) was an important revolt in 19th-century Vietnam, in which southern Vietnamese, Vietnamese Catholics, French Catholic missionaries and Chinese settlers under the leadership of Lê Văn Khôi opposed the rule of Emperor Minh Mạng.

The Panic of 1837 was a financial crisis in the United States that began a major depression which lasted until the mid-1840s. Profits, prices, and wages dropped, westward expansion was stalled, unemployment rose, and pessimism abounded. The panic had both domestic and foreign origins. Speculative lending practices in the West, a sharp decline in cotton prices, a collapsing land bubble, international specie flows, and restrictive lending policies in Britain were all factors. The lack of a central bank to regulate fiscal matters, which President Andrew Jackson had ensured by not extending the charter of the Second Bank of the United States, was also key. The ailing economy of early 1837 led investors to panic, and a bank run ensued, giving the crisis its name. The bank run came to a head on May 10, 1837, when banks in New York City ran out of gold and silver. They immediately suspended specie payments, and would no longer redeem commercial paper in specie at full face value. A significant economic collapse followed: despite a brief recovery in 1838, the recession persisted for nearly seven years. Over 40% of all banks failed, businesses closed, prices declined, and there was mass unemployment. From 1837 to 1844, deflation in wages and prices was widespread. As the nation underwent hardships, positive forces were at work that, in time, would invigorate the economy. Railroads had begun their relentless expansion, and furnace masters had discovered how to smelt greater quantities of pig iron. The machine tool and the metalworking industries were taking shape. Coal had begun its ascent, replacing wood as the nation's major source of heat. Innovations with agricultural machinery brought greater productivity from the land. The nation's population also increased by more than one-third during the 1840s, despite the economic turmoil (mostly due to immigration, especially Irish emigration during the Irish Famine). After downturns in 1845–1846 and 1847–1848, gold was discovered in California in 1848, setting off a prosperity of its own. Meanwhile, individuals and institutions were hurting.

The Astor Place Riot occurred on May 10, 1849, at the now-demolished Astor Opera House in Manhattan and left between 22 and 31 rioters dead, and more than 120 people injured. It was the deadliest to that date of a number of civic disturbances in Manhattan, which generally pitted immigrants and nativists against each other, or together against the wealthy who controlled the city's police and the state militia. The riot resulted in the largest number of civilian casualties due to military action in the United States since the American Revolutionary War, and led to increased police militarization (for example, riot control training and larger, heavier batons). Its ostensible genesis was a dispute between Edwin Forrest, one of the best-known American actors of that time, and William Charles Macready, a similarly notable English actor, which largely revolved around which of them was better than the other at acting the major roles of Shakespeare.

The Indian Rebellion of 1857 was a major uprising in India in 1857–58 against the rule of the British East India Company, which functioned as a sovereign power, including military forces, on behalf of the British Crown. The rebellion began on 10 May 1857 as a mutiny of sepoys of the company's garrison in Meerut, a town 40 miles (64 km) northeast of Delhi. It then erupted into other mutinies and civilian rebellions, chiefly in the upper Gangetic plain and central India, though incidents of revolt also occurred farther north and east. The rebellion posed a military threat to British power in that region, and was contained only with the rebels' defeat in Gwalior on 20 June 1858. On 1 November 1858, the British granted amnesty to all rebels not involved in murder, though they did not declare the hostilities to have formally ended until 8 July 1859. The name of the revolt is contested, and it is variously described as the Sepoy Mutiny, the Indian Mutiny, the Great Rebellion, the Revolt of 1857, the Indian Insurrection, and the First War of Independence. The Indian rebellion was fed by resentments born of diverse perceptions, including invasive British-style social reforms, harsh land taxes, summary treatment of some rich landowners and princes, and scepticism about British claims that their rule offered material improvement to the Indian economy. Many Indians rose against the British; however, many also fought for the British, and the majority remained seemingly compliant to British rule. Violence, which sometimes betrayed exceptional cruelty, was inflicted on both sides: on British officers and civilians, including women and children, by the rebels, and on the rebels and their supporters, including sometimes entire villages, by British reprisals; the cities of Delhi and Lucknow were laid waste in the fighting and the British retaliation. After the outbreak of the mutiny in Meerut, the rebels quickly reached Delhi, whose 81-year-old Mughal ruler, Bahadur Shah Zafar, was declared the Emperor of Hindustan. Soon, the rebels had captured large tracts of the North-Western Provinces and Awadh (Oudh). The East India Company's response came rapidly as well. With help from reinforcements, Kanpur was retaken by mid-July 1857, and Delhi by the end of September. However, it then took the remainder of 1857 and the better part of 1858 for the rebellion to be suppressed in Jhansi, Lucknow, and especially the Awadh countryside. Other regions of Company-controlled India— the Bengal Presidency, the Bombay Presidency, and the Madras Presidency—remained largely calm. In the Punjab, the Sikh princes crucially helped the British by providing both soldiers and support. The large princely states, Hyderabad, Mysore, Travancore, and Kashmir, as well as the smaller ones of Rajputana, did not join the rebellion, serving the British, in Governor-General Lord Canning's words, as "breakwaters in a storm". In some regions, most notably in Awadh, the rebellion took on the attributes of a patriotic revolt against British oppression. However, the rebel leaders proclaimed no articles of faith that presaged a new political system. Even so, the rebellion proved to be an important watershed in Indian and British Empire history. It led to the dissolution of the East India Company and forced the British to reorganize the army, the financial system, and the administration in India through passage of the Government of India Act 1858. India was thereafter administered directly by the British government in the new British Raj. On 1 November 1858, Queen Victoria issued a proclamation to Indians, which, while lacking the authority of a constitutional provision, promised rights similar to those of other British subjects. In the following decades, when admission to these rights was not always forthcoming, Indians were to pointedly refer to the Queen's proclamation in growing avowals of a new nationalism.

Kentucky, officially the Commonwealth of Kentucky, is a landlocked state in the Southeastern region of the United States. It borders Illinois, Indiana, and Ohio to the north, West Virginia to the northeast, Virginia to the east, Tennessee to the south, and Missouri to the west. Its northern border is defined by the Ohio River. Its capital is Frankfort and its most populous city is Louisville. As of 2024, the state's population was approximately 4.6 million.

America's first transcontinental railroad (known originally as the "Pacific Railroad" and later as the "Overland Route") was a 1,911-mile (3,075 km) continuous railroad line built between 1863 and 1869 that connected the existing eastern U.S. rail network at Council Bluffs, Iowa, with the Pacific coast at the Oakland Long Wharf on San Francisco Bay. The rail line was built by three private companies over public lands provided by extensive U.S. land grants. Building was financed by both state and U.S. government subsidy bonds as well as by company-issued mortgage bonds. The Western Pacific Railroad Company built 132 miles (212 km) of track from the road's western terminus at Alameda/Oakland to Sacramento, California. The Central Pacific Railroad Company of California (CPRR) constructed 690 miles (1,110 km) east from Sacramento to Promontory Summit, Utah Territory. The Union Pacific Railroad (UPRR) built 1,085 miles (1,746 km) from the road's eastern terminus at the Missouri River settlements of Council Bluffs and Omaha, Nebraska, westward to Promontory Summit. The railroad opened for through traffic between Sacramento and Omaha on May 10, 1869, when CPRR President Leland Stanford ceremonially tapped the gold "Last Spike" (later often referred to as the "Golden Spike") with a silver hammer at Promontory Summit. In the following six months, the last leg from Sacramento to San Francisco Bay was completed. The resulting coast-to-coast railroad connection revolutionized the settlement and economy of the American West. It brought the western states and territories into alignment with the northern Union states and made transporting passengers and goods coast-to-coast considerably quicker, safer and less expensive. The first transcontinental rail passengers arrived at the Pacific Railroad's original western terminus at Alameda Terminal on September 6, 1869, where they transferred to the steamer Alameda for transport across the Bay to San Francisco. The road's rail terminus was moved two months later to the Oakland Long Wharf, about a mile to the north, when its expansion was completed and opened for passengers on November 8, 1869. Service between San Francisco and Oakland Pier continued to be provided by ferry. The CPRR eventually purchased 53 miles (85 km) of UPRR-built grade from Promontory Summit (MP 828) to Ogden, Utah Territory (MP 881), which became the interchange point between trains of the two roads. The transcontinental line became popularly known as the Overland Route after the name of the principal passenger rail service to Chicago that operated over the length of the line until 1962.

Victoria Claflin Woodhull (born Victoria California Claflin; September 23, 1838 – June 9, 1927), later Victoria Woodhull Martin, was an American leader of the women's suffrage movement who ran for president of the United States in the 1872 election. While many historians and authors agree that Woodhull was the first woman to run for the presidency, some disagree with classifying it as a true candidacy because according to the Constitution she would have been too young to be president if elected. An activist for women's rights and labor reforms, Woodhull was also an advocate of "free love", by which she meant the freedom to marry, divorce and bear children without social restriction or government interference. "They cannot roll back the rising tide of reform", she often said. "The world moves." Woodhull twice went from rags to riches, her first fortune being made on the road as a magnetic healer before she joined the spiritualist movement in the 1870s. Together with her sister, Tennessee Claflin, she was the first woman to operate a brokerage firm on Wall Street, making a second fortune. They were among the first women to found a newspaper in the United States, Woodhull & Claflin's Weekly, which began publication in 1870. Authorship of many of her articles is disputed (many of her speeches on these topics were collaborations between Woodhull, her backers, and her second husband, Colonel James Blood). Woodhull was politically active in the early 1870s when she was nominated as the first woman candidate for the United States presidency. Woodhull was the candidate in 1872 from the Equal Rights Party, supporting women's suffrage and equal rights; her running mate (unbeknownst to him) was abolitionist leader Frederick Douglass. Her campaign inspired at least one other woman – apart from her sister – to run for Congress. A check on her activities occurred when she was arrested on obscenity charges a few days before the election. Her paper had published an account of the alleged adulterous affair between the prominent minister Henry Ward Beecher and Elizabeth Richards Tilton that had rather more detail than was considered proper at the time. However, it all added to the sensational coverage of her candidacy.

The Centennial International Exhibition, officially the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, was held in Philadelphia, Pennsylvania, from May 10 to November 10, 1876.

Karl Emil Malmelin (16 January 1872 – 26 February 1944) was a Finnish farmworker and mass murderer. Malmelin was born 1872 in Espoo as the illegitimate child of Helena Gustava Malmelin, a maid at a Lahnus croft. As an adult, Malmelin became a farmworker at the Simola croft in Klaukkala, a village in the southern part of the Nurmijärvi municipality. The tenant there was Johan Ezekiel Aspelin. Malmelin began dating Edla, the crofter's daughter, but when she would not become his wife, he killed everyone on the croft with an axe on 10 May 1899. Three of the victims were women and two were children. Malmelin was arrested a couple of weeks later. Malmelin was sentenced to life imprisonment by the Turku Court of Appeal. The case was the subject of a broadside ballad, and Nurmijärvi parish became popularly known as Murhajärvi (which literally means "murder lake"). Malmelin served 13 years of his sentence before being pardoned by Nicholas II in 1912. The later events of Malmelin's life remain unknown. He died to a long-term illness in 1944, aged 72, in Riipilä, Vantaa. Malmelin remains one of the worst axe murderers in Finnish history, along with Toivo Koljonen.

Kingman Reef is a largely submerged, uninhabited, triangle-shaped reef, geologically an atoll, 9.0 nmi (20 km) east-west and 4.5 nmi (8 km) north-south, in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa. It has an area of 3 hectares and is an unincorporated territory of the United States in Oceania. The reef is administered by the United States Fish and Wildlife Service as the Kingman Reef National Wildlife Refuge. It was claimed by the United States in 1859 and later used briefly as a stopover for commercial Pacific flying boat routes in the 1930s going to New Zealand; however, the route was changed with a different stopover. It was administered by the Navy from 1934 to 2000 and thereafter by the Fish and Wildlife Service. It has since become a marine protected area. In the 19th century, it was noted as a maritime hazard, earning the name Hazard Rocks, and is known to have been hit once in 1876. In the 21st century, it has been noted for its marine biodiversity and remote nature. Hundreds of fish and coral species are on and around the reef.

Censorship is the suppression of speech, public communication, or other information. This may be done on the basis that such material is considered objectionable, harmful, sensitive, or "inconvenient". Censorship can be conducted by governments and private institutions. When an individual such as an author or other creator engages in censorship of their own works or speech, it is referred to as self-censorship. General censorship occurs in a variety of different media, including speech, books, music, films, and other arts, the press, radio, television, and the Internet for a variety of claimed reasons including national security, to control obscenity, pornography, and hate speech, to protect children or other vulnerable groups, to promote or restrict political or religious views, and to prevent slander and libel. Specific rules and regulations regarding censorship vary between legal jurisdictions and/or private organizations.

A grenade is a small explosive projectile. It can be thrown by hand, launched by a rifle attachment, or launched by a dedicated launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and an arming safety secured by a transport safety. The user removes the transport safety pins before throwing, and once the grenade leaves the hand the arming safety gets released, allowing the striker to trigger a primer that ignites a fuze, which burns down to the detonator and explodes the main charge.

One World Trade Center, also known as One WTC and the Freedom Tower, is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City.

The solar storms of May 2024 were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10 to 13 May 2024 during solar cycle 25. Different names have been used for the event in different regions, including 2024 Mother's Day Storm , the Gannon storm, Han Anniversary Storm, and Victory Day Storm. Only a small fraction of the strongest geomagnetic storms of recent decades have acquired names commonly used by the scientific community, and the multiple names assigned to the May 2024 event have prompted calls for a standardized international system for naming space weather events. The geomagnetic storm was the most powerful to affect Earth since March 1989, and produced aurorae at far lower latitudes than usual.
