October 31 in History

Romulus Augustus (c. 460–465 – c. 511–530), nicknamed Augustulus, was Roman emperor of the West from 31 October 475 until 4 September 476. Romulus was placed on the imperial throne while still a minor by his father Orestes, the magister militum, for whom he served as little more than a figurehead. After a rule of ten months, the barbarian general Odoacer defeated and killed Orestes and deposed Romulus. As Odoacer did not proclaim any successor, Romulus is typically regarded as the last Western Roman emperor, his deposition marking the end of the Western Roman Empire as a political entity. The deposition of Romulus Augustulus is also sometimes used by historians to mark the transition from antiquity to the medieval period. Very few records survive of Romulus's reign. There are no known policies, laws or inscriptions of significance of the emperor, which leaves the impression that he was a shadowy and relatively inconsequential figure. The nickname "Augustulus" means "little Augustus" and was a derisive reference to his young age. Romulus's immediate family, including his father and possibly his mother, and maybe both his paternal and maternal grandparents, were from the Roman province of Pannonia, and many of his family members had military backgrounds. Romulus came to power through the usurpation of his predecessor Julius Nepos (r. 474–475 in Italy) in 475. Nepos fled to Dalmatia and continued to claim the imperial title in exile, which hampered Romulus's legitimacy and ensured that he was never recognised by the Eastern Roman emperor Zeno. In 476, the allied barbarian foederati in Italy demanded Italian lands to settle on, which was refused by Orestes. Under Odoacer, the foederati defeated and killed Orestes and deposed Romulus, whereafter Odoacer became the first King of Italy and accepted Emperor Zeno as his nominal superior. Romulus's life was spared by Odoacer, and he was allowed to retire to the castellum Lucullanum, a great fortress in Campania. Little certain information is known concerning Romulus's life in exile. He might have played a role in founding a monastery at castellum Lucullanum in the 480s or 490s, dedicated to Saint Severinus of Noricum. Romulus could have been alive as late as 507 or 511 when Theodoric the Great, Odoacer's successor, wrote a letter to a "Romulus" concerning a pension, but was likely dead before his mid-40s, as accounts of the eastern Roman invasion of Italy at that time do not mention him.

The Lateran Council of 649 was a synod held in the Basilica of St. John Lateran to condemn Monothelitism, a Christology espoused by many Eastern Christians, and (to some degree) Pope Honorius. The Council did not achieve ecumenical status in either East or West, but represented the first attempt of a pope to convene an ecumenical council independent of the Roman emperor. According to Andrew Ekonomou, the irony of the council was that the denunciation of the theology of Constantinople came from the "collaboration of a Greco-Palestinian pope and a Constantinopolitan monk employing a style of theological discourse whose tradition was purely Eastern." Although Pope Martin I and Maximus the Confessor were abducted by Constans II and tried in Constantinople for their role in the council (Martin I being replaced as pope before dying in exile), their position was ultimately endorsed by the Third Council of Constantinople in 680.

Irene of Athens (Greek: Εἰρήνη, Eirḗnē; 750/756 – 9 August 803), surname Sarantapechaena (Greek: Σαρανταπήχαινα, Sarantapḗchaina), was Byzantine empress consort to Emperor Leo IV from 775 to 780, regent during the childhood of their son Constantine VI from 780 until 790, co-ruler from 792 until 797, and finally empress regnant and sole ruler of the Byzantine Empire from 797 to 802. A member of the politically prominent Sarantapechos family, she was selected as Leo IV's bride for unknown reasons in 768. Even though her husband was an iconoclast, she harbored iconophile sympathies. During her regency, in 787, she called the Second Council of Nicaea which condemned iconoclasm as heretical and brought an end to the first iconoclast period (730–787). Irene's concluding five years of sole rule were unprecedented in Roman and Byzantine history. Her public figure in this period was polarizing, due to the setbacks faced by the Empire and her iconophilic stances, often attributed to her gender and the influence of her retinue. After the death of her husband, Irene secured the throne for her family, setting herself in charge. During her regency with Constantine VI, she became very influential in government policies, largely overshadowing her son. As Constantine VI reached maturity, he began to move out from under the influence of his mother. In the early 790s, several revolts attempted to proclaim him as sole ruler. One of these revolts succeeded, but in 792 Irene was re-established in all imperial powers as "co-emperor" with Constantine VI. In 797, Irene organized a conspiracy in which her supporters gouged out her son's eyes. Constantine was imprisoned and probably died shortly afterwards. With him out of the way, Irene proclaimed herself sole ruler. Pope Leo III—already seeking to break links with the Byzantine East—used Irene's alleged unprecedented status as a female ruler of the Roman Empire to proclaim Charlemagne as Emperor of the Romans on Christmas Day of 800 under the pretext that a woman could not hold the position solely and thus the Roman throne was actually vacant. A revolt in 802 overthrew Irene and exiled her to the island of Lesbos, supplanting her on the throne with Nikephoros I. Irene died in exile less than a year later.

The Abbasid Caliphate or Abbasid Empire was the third Islamic caliphate, ruled by the Abbasid dynasty. The dynasty was descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib, after whom it is named. The Abbasids rose to power in 750, when the Abbasid Revolution overthrew the preceding Umayyad Caliphate. They ruled as caliphs from their base in Iraq until 1258, with Baghdad as their capital for most of their history.

Leiden University Libraries is the set of libraries of Leiden University, founded in 1575 in Leiden, Netherlands. Holdings include some five million volumes, one million e-books, ninety thousand e-journals, two thousand current paper journals, and three thousand cuneiform tablets. The library manages large collections on Indonesia and the Caribbean, and curates seven entries in UNESCO's international and Dutch Memory of the World Register. Joseph Justus Scaliger, who was a languages and history professor at Leiden from 1593 up to 1609, commented in Latin on the library:Est hic magna commoditas bibliothecae ut studiosi possint studere. Here [at Leiden] is the great convenience of a library so that those who want to study [students], can study.

General John Churchill, 1st Duke of Marlborough, 1st Prince of Mindelheim, 1st Count of Nellenburg, Prince of the Holy Roman Empire was a British army officer and statesman. From a gentry family, he served as a page at the court of the House of Stuart under James, Duke of York, through the 1670s and early 1680s, earning military and political advancement through his courage and diplomatic skill. He is known for never having lost a battle.

Pyotr Stepanovich Kotlyarevsky (23 June 1782 – 2 November 1852) was a Russian military officer of Ukrainian origin. He was known for his service in the Russo-Persian War (1804–1813), where he won many battles against Iran.

Agustín Cosme Damián de Iturbide y Arámburu (Spanish pronunciation: [aɣusˈtin de ituɾˈbiðe] ; 27 September 1783 – 19 July 1824), commonly known as Agustín de Iturbide and later by his regnal name Agustín I, was a Mexican army officer and politician who served as the first Emperor of Mexico from 1822 until his abdication in 1823. A criollo from a family of Valladolid's landed gentry, Iturbide entered the royal Spanish army in 1805 and became one of the most important commanders in the Mexican War of Independence, repeatedly defeating the insurgent forces from 1810 to 1815, culminating in the capture and execution of José María Morelos in 1815. He was dismissed from command in 1816 for corruption and cruelty towards the insurgent forces, but was reinstated in 1820 to defeat Vicente Guerrero. However, fearing the onset of republicanism following Spain's restoration of the liberal constitution of 1812, Iturbide allied with the insurgents under the plan of Iguala of 1821, which aimed to turn Mexico into a monarchy, with Roman Catholicism as its official religion and the abolition of the racial caste system and slavery. The new Army of the Three Guarantees quickly defeated the Spanish forces, and on 27 September 1821 Iturbide marched into Mexico City; the next day, Mexico was proclaimed an independent empire. Iturbide was proclaimed president of the Regency in 1821. The refusal by Ferdinand VII of Spain to accept the Mexican crown paved the way for Iturbide to assume the mantle of emperor on 21 July 1822. His reign was turbulent, characterized by the political conflict with former insurgents, progressives and loyalists to Ferdinand VII, economic troubles and fears of a Spanish invasion. His dissolution of Congress on 31 October 1822 precipitated a military revolt in December led by Antonio López de Santa Anna, Guadalupe Victoria and Guerrero. With his forces defecting to the rebels, Iturbide decided to abdicate on 19 March 1823. In May 1823 he went into exile in Europe. When he returned to Mexico in July 1824, he was arrested and executed by a local legislature.

The Muscogee, Mvskoke or Mvskokvlke, also known as Muscogee Creek or just Creek, are a group of related Indigenous peoples of the Southeastern Woodlands in the United States. Their historical homelands are in what now comprises southern Tennessee, much of Alabama, western Georgia and parts of northern Florida.

The New Zealand Wars took place from 1845 to 1872 between the New Zealand colonial government and allied Māori on one side, and Māori and Māori-allied settlers on the other.

Nevada ( , nə-VAD-ə; Spanish: [ne.ˈβa.ða] ) is a landlocked state in the Western United States. It is also sometimes placed in the Mountain West and Southwestern United States. It borders Idaho to the northeast, Oregon to the northwest, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the seventh-most extensive and the 31st-most populous U.S. state. Nearly three-quarters of Nevada's population live in Clark County, which contains the Las Vegas–Paradise metropolitan area. Nevada's capital is Carson City. Las Vegas is the largest city in the state. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War; as the "Sagebrush State", for the native plant of the same name; and as the "Sage-hen State". Native Americans of the Paiute, Shoshone, and Washoe tribes inhabit what is now Nevada. The first Europeans to explore the region were Spanish. They called the region Nevada (snowy) because of the snow which covered the mountains in winter, similar to the Sierra Nevada in Spain. The area formed from mostly Alta California and part of Nuevo México's territory within the Viceroyalty of New Spain, which gained independence as Mexico in 1821. The United States annexed the area in 1848 after its victory in the Mexican–American War, and it was incorporated as part of the New Mexico and Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a population boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31, 1864, as the second of two states added to the Union during the Civil War (the first being West Virginia). Nevada is known for its libertarian laws. In 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populous state, Wyoming. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century. Nevada is the only U.S. state where prostitution is legal, though it is illegal in its most populated regions – Clark County (Las Vegas), Washoe County (Reno) and Carson City (which, as an independent city, is not within the boundaries of any county). The tourism industry remains Nevada's largest employer, with mining continuing as a substantial sector of the economy: Nevada is the fourth-largest producer of gold in the world. The state's name means "snowy" in Spanish, referring to Nevada's extensive number of mountain ranges capped with snow in winter, which help make Nevada among the highest US states by mean altitude. These include the Carson Range portion of the Sierra Nevada (and about 1/3 of Lake Tahoe by surface area), as well as the Toiyabe Range, Ruby Mountains, and Spring Mountains (which exemplify the sky islands of the Great Basin montane forests), in western, central, northeastern, and southern Nevada, respectively. Nevada is the driest U.S. state, both lying in the rain shadow of the Sierra Nevada and receiving among the highest solar irradiance of any U.S. state, and is thus largely desert and semi-arid. Nevada comprises the majority of the Great Basin, as well as a large portion of the Mojave Desert. In 2020, 80.1% of the state's land was managed by various jurisdictions of the U.S. federal government, both civilian and military. Droughts in Nevada, which are influenced by climate change, have been increasing in frequency and severity, putting a further strain on Nevada's water security. Nonetheless, Nevada is among the leaders in adapting to climate change, including via climate science at Desert Research Institute, extensive water recycling in the Las Vegas metropolitan area, voter-mandated investment in solar power, hosting leading electric vehicle manufacturing ecosystem resources at the largest industrial park in the U.S., and developing the largest lithium mine in the U.S. for use in electric batteries.

The Purdue wreck was a railroad train collision in Indianapolis, Indiana, on Saturday, October 31, 1903, between two special trains that killed 17 people, including 14 players of the 1903 Purdue University football team. Team captain and future Indiana governor Harry G. Leslie was initially thought to have died in the accident, but was later revived.

The Parliament of Finland is the unicameral and supreme legislature of Finland, founded on 9 May 1906. In accordance with the Constitution of Finland, sovereignty belongs to the people, and that power is vested in the Parliament. The Parliament consists of 200 members, 199 of whom are elected every four years from 13 multi-member districts electing 6 to 37 members using the proportional D'Hondt method. In addition, there is one member from Åland.

The Lincoln Highway is one of the first transcontinental highways in the United States and one of the first highways designed expressly for automobiles. Conceived in 1912 by Indiana entrepreneur Carl G. Fisher, and formally dedicated October 31, 1913, the Lincoln Highway runs coast-to-coast from Times Square in New York City west to Lincoln Park in San Francisco. The full route originally ran through 13 states: New York, New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Colorado, Wyoming, Utah, Nevada, and California. In 1915, the "Colorado Loop" was removed, and in 1928, a realignment routed the Lincoln Highway through the northern tip of West Virginia. Thus, there are 14 states, 128 counties, and more than 700 cities, towns, and villages through which the highway passed at some time in its history. The first officially recorded length of the entire Lincoln Highway in 1913 was 3,389 miles (5,454 km). Over the years, the road was improved and numerous realignments were made, and by 1924 the highway had been shortened to 3,142 miles (5,057 km). Counting the original route and all of the subsequent realignments, the path has included a grand total of 5,872 miles (9,450 km). The Lincoln Highway was gradually replaced with numbered designations after the establishment of the U.S. Numbered Highway System in 1926, with most of the route becoming U.S. Route 30 from Pennsylvania to Wyoming. After the Interstate Highway System was formed in the 1950s, the former alignments of the Lincoln Highway were largely superseded by Interstate 80 as the primary coast-to-coast route from the New York City area to San Francisco.

The Indianapolis streetcar strike of 1913 and the subsequent police mutiny and riots was a civil conflict in Indianapolis, Indiana. The events began as a workers strike by the union employees of the Indianapolis Traction and Terminal Company and their allies on Halloween night, October 31, 1913. The company was responsible for public transportation in Indianapolis, the capital city and transportation hub of the U.S. state of Indiana. The unionization effort was being organized by the Amalgamated Street Railway Employees of America who had successfully enforced strikes in other major United States cities. Company management suppressed the initial attempt by some of its employees to unionize and rejected an offer of mediation by the United States Department of Labor, which led to a rapid rise in tensions, and ultimately the strike. Government response to the strike was politically charged, as the strike began during the week leading up to public elections. The strike effectively shut down mass transit in the city and caused severe interruptions of statewide rail transportation and the 1913 city elections. A riot that lasted four days broke out on November 2 when strikebreakers attempted to restart transit services. At its height, eight to ten thousand rioters flooded downtown Indianapolis and vandalized the city's main business district. Numerous workers, strikebreakers, policemen, and bystanders were injured. Two strikebreakers and four union members were killed. The city police were unable to control the situation and refused orders to combat the rioters as the violence worsened. After pleas for help from city leaders following continued rioting on Election Day, Governor Samuel Ralston called out the Indiana National Guard and put the city under martial law on the evening of November 5. On November 6, an angry crowd surrounded the Indiana Statehouse, listed their grievances, demanded the military leave the city, and threatened more violence if their demands were not met. Ralston addressed the crowd to promise concessions if the workers would return to work. His speech was credited by the press with ending the strike. After three days of peace, the military withdrew from the city. The Indiana General Assembly met later that month and enacted Indiana's first minimum wage laws, regular working hours, workplace safety requirements, and began projects to improve the city's tenement slums. Arbitration between the company and its employees by the Indiana Public Service Commission resulted in a decision mostly favoring the company. The employees were permitted to unionize, guaranteed wage increases, a minimum monthly salary, and certain days off work. The company, however, was permitted to continue hiring non-union employees and to bar union membership solicitation on the company's property.

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 caused 15 to 22 million deaths, including those resulting from war crimes and genocides. The war also contributed to the spread of the Spanish flu pandemic. The conflict saw important developments in weaponry, including machine guns, artillery, aircraft, chemical weapons, and tanks.

The Aster Revolution or Chrysanthemum Revolution (Hungarian: Őszirózsás forradalom) was a revolution in Hungary led by Count Mihály Károlyi in the aftermath of World War I. It resulted in the foundation of the short-lived First Hungarian People's Republic. The revolution was brought about by widespread protests as World War I wore on, from which Mihály Károlyi emerged as the leader of the newly proclaimed First Hungarian People's Republic. This lasted between 16 November 1918 and 21 March 1919. Supporters of Károlyi, many of whom were demobilised soldiers, adopted the aster as the symbol of the revolution. Following its success, Hungary declared its independence. As a result, Austria-Hungary dissolved.

Benito Amilcare Andrea Mussolini (29 July 1883 – 28 April 1945) was a fascist dictator who was the prime minister of Italy from 1922 until his deposition in 1943. Known as Il Duce during his rule, he established a totalitarian dictatorship led by the National Fascist Party (PNF) in the Kingdom of Italy. Born in Predappio, Mussolini originally worked as a journalist for the Italian Socialist Party (PSI) newspaper Avanti!. He was expelled from the party for advocating military intervention in World War I and called up for the Royal Italian Army in 1915, where he served until his discharge after being wounded in 1917. During the war, Mussolini turned to nationalism and denounced the PSI. He founded the Fasci Italiani di Combattimento in 1919, which opposed egalitarianism and class conflict and instead promoted a form of revolutionary nationalism transcending class lines. The Combattimento are often considered the world's first fascist movement. The Combattimento were reorganised into the PNF in 1921. Fascist militants marched on Rome and Mussolini was appointed prime minister by King Victor Emmanuel III in 1922. He established the OVRA in 1927 to silence opposition, outlawed labour strikes, and consolidated power through the Acerbo Law among others, transforming Italy from a parliamentary democracy into a one-party state. He ordered the Pacification of Libya, characterised by some scholars as a genocide, and signed the Lateran Treaty to formally establish the Vatican City in 1929. Mussolini generally espoused autarkist and corporatist policies to grow the Italian economy, especially after the Great Depression. Mussolini's foreign policy shifted from cautious pragmatism to aggressive expansion and close alignment with Nazi Germany in the mid-1930s. Initially, he sought to expand Italy's influence without risking a major conflict with France or Britain, aligning with them during tensions over Austria. However, his invasion of Ethiopia resulted in condemnations from the League of Nations, which isolated Italy diplomatically. This pushed Mussolini toward Adolf Hitler, leading to a rapprochement and the formation of the Rome–Berlin Axis in 1936. Mussolini began militarily supporting Francisco Franco's forces during the Spanish Civil War. Although he acted as a mediator at the Munich Conference in 1938, his ambitions for territorial expansion and growing distrust of the Western powers led him to strengthen ties with Germany, resulting in the creation of the Pact of Steel in 1939. The wars of the 1930s cost Italy enormous resources, leaving it unprepared for World War II; Mussolini initially declared Italy's non-belligerence. However, in June 1940, believing that German victory was imminent, he joined the war on Germany's side to share the spoils. Following defeats at the hands of the Allies and the landing in Sicily, the Grand Council of Fascism voted on the Grandi motion, which effectively ended Mussolini's leadership and restored powers to King Victor Emmanuel III who then immediately dismissed Mussolini as head of government and placed him in custody in July 1943. After the king agreed to an armistice with the Allies in September 1943, Mussolini was rescued by the Germans during the Gran Sasso raid. Hitler made Mussolini the figurehead of a puppet state in German-occupied north Italy, the Italian Social Republic, which served as a collaborationist regime of Germany. With Allied victory imminent, Mussolini and his mistress Clara Petacci attempted to flee to Switzerland, but were captured by communist partisans and summarily executed on 28 April 1945.

The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride. The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F.

The World Savings Day was established on October 31, 1924, during the 1st International Savings Bank Congress (World Society of Savings Banks) in Milan, Italy. The Italian Professor Filippo Ravizza declared this day the "International Saving Day" on the last day of the congress. In the resolutions of the Thrift Congress it was decided that 'World Thrift Day' should be a day devoted to the promotion of savings all over the world. In their efforts to promote thrift, the savings banks also worked with the support of the schools, the clergy, as well as cultural, sports, professional, and women's associations. Representatives of 29 countries wanted to bring to mind the "thought of saving" to the worldwide public and its relevance to the economy and the individual. The World Savings Day is usually held on October 31 except in countries where this day is a public holiday, since the idea is for the banks to be open, so that the people are able to transfer their savings into their account. The idea of World Thrift Day was not created spontaneously. There had been examples of other days committed to the idea of saving money in order to gain a higher standard of life and to secure the economy; for example, in Spain, the first national thrift day was celebrated in 1921, or in the United States. In other countries, such as Germany, the peoples' confidence in savings had to be restored since many of them had lost their savings in the German monetary reform of 1923. After the Second World War, World Thrift Day continued and reached the peak of its popularity in the years between 1955 and 1970. It practically became a veritable tradition in certain countries. In Austria, for instance, the official mascot of saving, the so-called 'Sparefroh' (lit. 'Happy Saver', or rather "save happily!") reached a higher degree of brand awareness than the republic's President and even a street was named after him. In the 1970s, the 'Sparefroh-Journal', an educational magazine for younger people, reached a circulation of 400,000 copies. Nowadays the focus of the banks that organise the World Savings Day is on developing countries, where many people are unbanked. Savings banks play an important role in enhancing savings in these countries with certain campaigns and initiatives such as working with non-governmental organisations in order to double the number of savings accounts held by the poor.

The Great Depression was a severe global economic downturn from 1929 to 1939. The period was marked by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street crash of 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Germany.

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 Mount Rushmore National Memorial is a national memorial featuring a colossal sculpture carved into the granite face of Mount Rushmore (Lakota: Tȟuŋkášila Šákpe Pahá, or Six Grandfathers Mountain) in the Black Hills, about 2 mi (3 km) southwest of Keystone, South Dakota, United States. The sculptor, Gutzon Borglum, named it the Shrine of Democracy, and oversaw the execution from 1927 to 1941 with the help of his son, Lincoln Borglum. The sculpture features 60-foot-tall (18 m) depictions of the heads of four United States presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln, respectively chosen to represent the nation's foundation, expansion, development, and preservation. Mount Rushmore attracts more than two million visitors annually to the memorial park which covers 1,278 acres (2.00 sq mi; 517 hectares). Mount Rushmore is 3.7 mi (6.0 km) east-northeast of the summit of Black Elk Peak (formerly Harney Peak), the highest point in the Black Hills. Mount Rushmore is considered part of the Black Elk Range (formerly the Harney Range) in treatments that distinguish that subrange of the Black Hills. Its elevation at its highest point is 5,725 feet (1,745 m) above sea level. Borglum chose Mount Rushmore in part because of its southeast-facing direction and maximum exposure to sunlight. The carving was the idea of Doane Robinson, South Dakota's state historian. Robinson originally wanted the sculpture to feature American West heroes, such as Lewis and Clark, their expedition guide Sacagawea, Oglala Lakota chief Red Cloud, Buffalo Bill Cody, and Oglala Lakota chief Crazy Horse. Borglum, arguing that the sculpture should be national in scope rather than regional, convinced them to choose the four presidents instead. Peter Norbeck, U.S. senator from South Dakota, sponsored the project and secured federal funding. Construction began in 1927 and the presidents' faces were completed between 1934 and 1939. After Gutzon Borglum died in March 1941, his son Lincoln took over as leader of the construction project. Each president was originally to be depicted from head to waist, but lack of funding forced construction to end on October 31, 1941, and only Washington's sculpture includes any detail below chin level. The sculpture at Mount Rushmore was built on land that was taken from the Sioux Nation in the 1870s. In 1980, the U.S. Supreme Court ruled in United States v. Sioux Nation of Indians that the taking of the Black Hills required just compensation and awarded the tribe $102 million. The Sioux have refused the money, and continue to demand return of the land. This conflict continues, leading some critics of the monument to refer to it as a "Shrine of Hypocrisy".

USS Reuben James (DD-245) was a four-funnel Clemson-class destroyer that was constructed after World War I. She was the first United States Navy ship to be named after Boatswain's Mate Reuben James, who had distinguished himself fighting in the First Barbary War, and was the first US navy ship to be sunk by hostile action in the European Theater of World War II. Four US flagged merchant ships were also sunk by hostile action before the attack on Pearl Harbor.

The Vought F4U Corsair is an American fighter aircraft that saw service primarily in World War II and the Korean War. Designed and initially manufactured by Chance Vought, the Corsair was soon in great demand; additional production contracts were given to Goodyear, whose Corsairs were designated FG, and Brewster, designated F3A.

The Suez Crisis, also known as the second Arab–Israeli war, the Tripartite Aggression in the Arab world and the Sinai War in Israel, was a British–French–Israeli invasion of Egypt in 1956. Israel invaded on 29 October, with the primary objective of re-opening the Straits of Tiran and the Gulf of Aqaba as the recent tightening of the eight-year-long Egyptian blockade prevented Israeli passage. After issuing a joint ultimatum for a ceasefire, the United Kingdom and France joined the Israelis on 31 October in an attempt to depose Egyptian president Gamal Abdel Nasser and regain control of the Suez Canal (which Nasser had nationalised earlier that year). The countries came under heavy political pressure from the United States, the Soviet Union and the United Nations, prompting their withdrawal from Egypt. The crisis demonstrated that the United Kingdom and France could no longer implement independent foreign policies without U.S. consent. Israel's four-month-long occupation of the Egyptian-occupied Gaza Strip and Egypt's Sinai Peninsula enabled it to freely navigate the Straits of Tiran, but the Suez Canal was closed from October 1956 to March 1957. The crisis strengthened Nasser's standing, internationally humiliating the British (as historians questioned its role as a superpower) and the French during the Cold War. The UN established an emergency force to police the Egypt–Israel border. For his diplomatic efforts to resolve the conflict through the UN, Canadian external-affairs minister Lester B. Pearson received the Nobel Peace Prize. Analysts have said that the crisis may have emboldened the USSR, facilitating the Soviet invasion of Hungary.

The Hungarian Revolution of 1956 (23 October – 4 November 1956; Hungarian: 1956-os forradalom), also known as the Hungarian Uprising, was an attempted countrywide revolution against the government of the Hungarian People's Republic (1949–1989) and the policies caused by the government's subordination to the Union of Soviet Socialist Republics (USSR). The uprising lasted 15 days before being crushed by Soviet tanks and troops on 7 November 1956 (outside of Budapest, firefights lasted until at least 12 November 1956). Thousands were killed or wounded, and nearly a quarter of a million Hungarians fled the country. The Hungarian Revolution began on 23 October 1956 in Budapest when university students appealed to the civil populace to join them at the Hungarian Parliament Building to protest the USSR's geopolitical domination of Hungary through the communist government of Mátyás Rákosi. A delegation of students entered the building of Magyar Rádió to broadcast their sixteen demands for political and economic reforms to civil society, but were detained by security guards. When the student protesters outside the radio building demanded the release of their delegation, a group of police from the ÁVH (State Protection Authority) fatally shot several of the students. The siege of the Radio building began shortly after midnight and ended around 8 a.m. At that point, the revolutionaries broke into the building and treated the soldiers, officer cadets, and members of the ÁVH (State Protection Authority) found there as prisoners. ÁVH officer Major Fehér was executed with a shot to the back of the head. Consequently, Hungarians organized into revolutionary militias to fight the ÁVH; local Hungarian communist leaders and ÁVH policemen were captured and summarily executed, and political prisoners were released and armed. To realize their political, economic, and social demands, local soviets (councils of workers) assumed control of municipal government from the Hungarian Working People's Party (Magyar Dolgozók Pártja). The new government of Imre Nagy disbanded the ÁVH (on 28 October), declared Hungary's withdrawal from the Warsaw Pact (on 1 November), and pledged to reestablish free elections. By the end of October, the intense fighting had subsided. Although initially showing willingness to negotiate the withdrawal of the Soviet Army from Hungary (having negotiations on 3 November), the USSR repressed the Hungarian Revolution on 4 November, and fought the Hungarian revolutionaries until Soviet victory on 10 November; repression of the Hungarian Uprising killed 2,000 Hungarians and 700 Soviet Army soldiers, and compelled 200,000 Hungarians to seek political refuge abroad, mostly in Austria.

The Provisional Irish Republican Army, officially known as the Irish Republican Army and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent socialist republic, which would encompass all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, the sole legitimate successor to the original IRA from the Irish War of Independence. It was designated a terrorist organisation in the United Kingdom and an unlawful organisation in the Republic of Ireland, both of whose authority it rejected.

In the Iraq disarmament crisis of the early 2000s, Iraq, led by president Saddam Hussein, was pressured by the United States and its other adversaries to destroy alleged stockpiles of weapons of mass destruction (WMD)—biological, chemical, and nuclear. In the 1980s, Iraq had programs to produce all three, but in the 1990s, the programs were ended, and the WMD were destroyed. The U.S.' rationale for its 2003 invasion of Iraq was that the country still had WMD, and would use them.

In world demographics, the world population is the total number of humans currently alive. It was estimated by the United Nations to have exceeded 8 billion (8,000,000,000) on November 15, 2022. It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 218 more years from there to reach 8 billion. As of 2026, the world population is approximately 8.3 billion. However, this figure is only a very rough approximation.
