July 31 in History

The Gildonic War (Latin: Bellum Gildonicum) was a rebellion in the year 398 led by Comes Gildo against Roman emperor Honorius. The revolt was subdued by Stilicho, the magister militum of the Western Roman Empire.

Mount Fuji is an active stratovolcano located on the Japanese island of Honshu, with a summit elevation of 3,776.24 m. It is the highest mountain in Japan, the second-highest volcano on any Asian island, and the seventh-highest peak of an island on Earth. Mount Fuji last erupted from 1707 to 1708.

John Komnenos (Latinized as Comnenus), nicknamed "the Fat" (Greek: Ἰωάννης Κομνηνὸς ὁ παχύς, romanized: Ioannis Komninos o pahys), was a Byzantine noble who attempted to usurp the imperial throne from Alexios III Angelos in a short-lived coup in Constantinople on 31 July 1201 (or 1200). The coup drew on opposition to the ruling Angelid dynasty among rival aristocratic families and the common people, who were dissatisfied by the dynasty's failures against external foes. John had previously been an obscure figure, but he became the figurehead of the uprising because of his imperial blood, as he was descended from the illustrious Komnenian dynasty (1081–1185). However, the real driving force behind his coup was probably the ambitious Alexios Doukas Mourtzouphlos. With the support of the capital's populace, the plotters managed to seize most of the Great Palace in Constantinople's southeastern corner, which the mob proceeded to loot, and John Komnenos was crowned in the Hagia Sophia. Alexios III, however, was secure in his residence in the northwestern Palace of Blachernae, and he sent forces by sea to land in the part of the Great Palace still held by the loyal Varangian Guard. Most of the urban mob dispersed for the night, and the Varangians had little difficulty in suppressing the coup. John Komnenos was captured and executed with many of his followers.

The Hundred Years' War was a series of conflicts between the kingdoms of England and France and a civil war in France during the late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years. However, it was an intermittent conflict which was frequently interrupted by external factors, such as the Black Death, and several years of truces.

Jacques Cœur was a French government official and state-sponsored merchant whose personal fortune became legendary and led to his eventual disgrace. He initiated regular trade routes between France and the Levant. His memory retains iconic status in Bourges, where he built a palatial house that is preserved to this day.

The Alhambra Decree (also known as the Edict of Expulsion; Spanish: Decreto de la Alhambra, Edicto de Granada) was an edict issued on 31 March 1492 by the joint Catholic Monarchs of Spain, Isabella I of Castile and Ferdinand II of Aragon, ordering the expulsion of unconverted Jews from the Crowns of Castile and Aragon and its territories and possessions by 31 July of that year. Its primary purpose was to minimize the influence of the remaining Jews on Spain's large converso New Christian population, converted from Judaism, to minimize the possibility that the latter and their descendants would be able to secretly practice their former faith. Over half of Spain's Jews had converted as a result of the religious persecution and pogroms which occurred in 1391. Due to continuing attacks, around 50,000 more had converted by 1415. A further number of those remaining chose to convert to avoid expulsion. As a result of the Alhambra Decree and persecution in the years leading up to the expulsion of Spain's estimated 300,000 Jewish origin population, a total of over 200,000 had converted to Catholicism in order to remain in Spain, and between 40,000 and 100,000 remained Jewish and suffered expulsion. An unknown number of the expelled eventually succumbed to the pressures of life in exile away from formerly-Jewish relatives and networks back in Spain, and so converted to Catholicism to be allowed to return in the years following expulsion.:17 In 1924, the regime of Primo de Rivera granted Spanish citizenship to a part of the Sephardic Jewish diaspora, though few people benefited from it in practice. The decree was then formally and symbolically revoked on 16 December 1968 by the regime of Francisco Franco, following the Second Vatican Council. This was a full century after Jews had been openly practising their religion in Spain and synagogues were once more legal places of worship under Spain's Laws of Religious Freedom. In 2015, the government of Spain passed a law allowing dual citizenship to Jewish descendants who apply, to "compensate for shameful events in the country's past". Thus, Sephardic Jews who could prove that they are the descendants of those Jews expelled from Spain because of the Alhambra Decree would "become Spaniards without leaving home or giving up their present nationality". The Spanish law expired in 2019, and new applications for Spanish citizenship on the basis of Sephardic Jewish family heritage are no longer allowed. However, the descendants of the Jews exiled from the Iberian Peninsula may still apply for Portuguese citizenship.

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.

Maurice of Orange (Dutch: Maurits van Oranje; 14 November 1567 – 23 April 1625) was stadtholder of all the provinces of the Dutch Republic—except Friesland—from 1585 until his death. Prior to inheriting the title Prince of Orange from his elder half-brother, Philip William, in 1618, he was known as Maurice of Nassau (Dutch: Maurits van Nassau). Born in Dillenburg, Nassau, Maurice was educated at the Heidelberg University and the University of Leiden. He succeeded his father, William the Silent, as stadtholder of Holland and Zeeland in 1585, and later assumed the same position in Utrecht, Guelders, and Overijssel (1590), and Groningen (1620). As Captain-General and Admiral of the Union, Maurice reorganized the Dutch States Army, transforming the Dutch Revolt into a disciplined and effective military campaign. Working alongside the Land's Advocate of Holland, Johan van Oldenbarnevelt, Maurice led a series of victories that drove Spanish forces from much of the northern and eastern Netherlands. He gained wide recognition as one of the foremost military strategists of his time, particularly for his innovations in siege warfare and the development of a modern military drill system. He is widely credited with pioneering training methods that drew from classical principles outlined by Vegetius, forming one of the basis for early modern European armies. During the Twelve Years' Truce (1609–1621), a theological and political conflict broke out within the Republic, culminating in a power struggle between Maurice and Oldenbarnevelt. The dispute ended with Oldenbarnevelt's arrest and execution by beheading in 1619, a controversial act that marked a shift in Maurice's political role. After the truce, his military campaigns saw little further success. Maurice died in The Hague in 1625 without legitimate issue. He was succeeded by his half-brother, Frederick Henry. The island of Mauritius was named in his honor.

The Polish–Russian War of 1654–1667 was a major conflict between the Tsardom of Russia and the Polish–Lithuanian Commonwealth. Between 1655 and 1660, the Swedish invasion was also fought in the Polish–Lithuanian Commonwealth and so the period became known as "The Deluge". The Commonwealth initially suffered defeats, but it regained its ground and won several decisive battles. However, its plundered economy was not able to fund the long conflict. Facing internal crisis and civil war, the Commonwealth was forced to sign a truce. The war ended with significant Russian territorial gains and marked the beginning of the rise of Russia as a great power in Eastern Europe.

Alamgir I (Muhi al-Din Muhammad; 3 November 1618 – 3 March 1707), commonly known by the title Aurangzeb, was the sixth Mughal emperor, reigning from 1658 until his death in 1707. Under his reign, the Mughal Empire reached its greatest extent, with territory spanning nearly the entirety of the Indian subcontinent. Aurangzeb and the Mughals belonged to a branch of the Timurid dynasty. He held administrative and military posts under his father Shah Jahan (r. 1628–1658) and gained recognition as an accomplished military commander. Aurangzeb served as the viceroy of the Deccan in 1636–1637 and the governor of Gujarat in 1645–1647. He jointly administered the provinces of Multan and Sindh in 1648–1652 and continued expeditions into the neighbouring Safavid territories. In September 1657, Shah Jahan nominated his eldest and liberalist son Dara Shikoh as his successor, a move repudiated by Aurangzeb, who proclaimed himself emperor in February 1658. In April 1658, Aurangzeb defeated the allied army of Shikoh and the Kingdom of Marwar at the Battle of Dharmat. Aurangzeb's decisive victory at the Battle of Samugarh in May 1658 cemented his sovereignty and his suzerainty was acknowledged throughout the Empire. After Shah Jahan recovered from illness in July 1658, Aurangzeb declared him incompetent to rule and imprisoned his father in the Agra Fort. Following this, Aurangzeb had Dara Shikoh executed by beheading and his head was placed in a box and presented to their imprisoned father. Aurangzeb's reign is characterised by a period of rapid military expansion, with several dynasties and states being overthrown by the Mughals and many atrocities against non-Muslims. The Mughals also surpassed Qing China as the world's largest economy and biggest manufacturing power. The Mughal military gradually improved and became one of the strongest armies in the world. A staunch Muslim, Aurangzeb is credited with the construction of numerous mosques and patronising works of Arabic calligraphy. He successfully imposed the Fatawa-i Alamgiri as the principal regulating body of the empire and prohibited religiously forbidden activities in Islam. Although Aurangzeb suppressed several local revolts, he maintained cordial relations with foreign governments. His empire was also one of the largest in Indian history. However, his emperorship has a complicated legacy. He is often criticized for his actions against non-Muslims, including his ordering of the demolition of non-Muslim schools and temples and the reimposition of the jizya, a tax on non-Muslims, which had been suspended for the previous 100 years by his great-grandfather Akbar. He has also been criticized for his conservative view of Islam, with some arguing that he abandoned the legacy of pluralism and tolerance of the earlier Mughal emperors.

The Peace of Breda, or Treaty of Breda was signed in the Dutch city of Breda, on 31 July 1667. It consisted of three separate treaties between England and each of its opponents in the Second Anglo-Dutch War: the Dutch Republic, France, and Denmark–Norway. It also included a separate Anglo-Dutch commercial agreement. Negotiations had been in progress since late 1666 but were slow, as both sides tried to improve their positions. This changed after the French invasion of the Spanish Netherlands in late May, which the Dutch viewed as a more serious threat. War-weariness in England was increased by the June Raid on the Medway. Both factors led to a rapid agreement of terms. Among the terms was confirmation of colonial territories taken in the War, including Suriname to the Dutch and New Netherland (New York) to the English. Prior to 1667, the Anglo-Dutch relationship had been dominated by commercial conflict, which the treaty did not end entirely. However, tensions decreased markedly and cleared the way for the 1668 Triple Alliance between the Dutch Republic, England and Sweden. With the brief anomaly of the 1672 to 1674 Third Anglo-Dutch War, the treaty marked the beginning of an alliance between the English and the Dutch that would last for a century.

Daniel Defoe was an English writer, journalist, merchant and spy. He is famous for his novels Robinson Crusoe (1719), Moll Flanders (1722) and Roxana: The Fortunate Mistress (1724). He has been seen as one of the earliest proponents of the English novel, and helped to popularise the form in Britain with others such as Aphra Behn and Samuel Richardson.

The 1715 Treasure Fleet was a combination of two Spanish treasure fleets returning from the New World to Spain, the "Nueva España Fleet", under Captain-General Don Juan Esteban de Ubilla, and the "Tierra Firme Fleet", under Don Antonio de Echeverz y Zubiza. At two in the morning on Wednesday, July 31, 1715, seven days after departing from Havana, Cuba, all eleven ships of the fleet were lost in a hurricane along the east coast of Florida. A 12th ship, the French frigate Le Grifon, had sailed with the fleet. Its captain was unfamiliar with the Florida coastline and elected to stay further out to sea. Le Grifon safely returned to Europe. Because the fleet was carrying silver, it is also known as the 1715 Plate Fleet (plata being the Spanish word for silver). Some artifacts and even coins still wash up on Florida beaches from time to time. According to Cuban records, around 1,500 sailors perished while a small number survived in lifeboats. Many ships, including pirates, took part in the initial salvage. Initially a privateer, Henry Jennings was first accused of piracy for attacking such salvage ships and claiming their salvages. By the end of August, relief ships from Havana arrived at the site of the sunken fleet. After Urca de Lima's cargo was salvaged, she was burned down to the waterline to hide her position from pirates and privateers of other nations, who had become aware of the sunken treasure fleet as well. In December, the pirates Henry Jennings and Charles Vane captured a Spanish mail ship and got the exact position of the main Spanish salvage camp and Urca de Lima from her captain, Pedro de la Vega. They surprised the camp with a superior force and Salmón had no choice but to surrender the rest of the salvaged treasure that still remained in the camp. The pirates made off with about £87,500 of gold and silver.

Charles VII (6 August 1697 – 20 January 1745) was elector of Bavaria from 26 February 1726 and Holy Roman Emperor from 24 January 1742 to his death on 20 January 1745. He was also King of Bohemia (as Charles Albert) from 1741 to 1743. Charles was a member of the House of Wittelsbach, and his reign as Holy Roman Emperor thus marked the end of three centuries of uninterrupted Habsburg imperial rule, although he was related to the Habsburgs by both blood and marriage. Charles was the eldest son of Elector Maximilian II Emanuel of Bavaria and the Polish princess Theresa Kunegunda Sobieska. He became elector following the death of his father in 1726. In 1722, Charles married Archduchess Maria Amalia of Austria, daughter of Joseph I, Holy Roman Emperor and niece of Charles VI, Holy Roman Emperor. The couple had seven children together. After Charles VI died in 1740, Elector Charles claimed the Archduchy of Austria and briefly gained hold of the Bohemian throne. In 1742, he was elected emperor of the Holy Roman Empire. He ruled until his death three years later.

The Odawa are an Indigenous North American people who primarily inhabit land in the Eastern Woodlands region, now in jurisdictions of the northeastern United States and southeastern Canada. Their territory long preceded the creation of the current border between the two countries in the 18th and 19th centuries.

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.

A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time, in exchange for publishing an enabling disclosure of the invention. It offers a bargain between society and inventor: for a limited period of exclusivity, the inventor agrees to make the invention public rather than to keep it secret. In most countries, patent rights fall under private law and the patent holder must sue someone infringing the patent in order to enforce their rights.

Christchurch ( ; Māori: Ōtautahi) is the largest city in the South Island and the second-largest city by urban area population in New Zealand. Christchurch has an urban population of 407,800, and a metropolitan population of 556,500. It is located in the Canterbury Region, near the centre of the east coast of the South Island, east of the Canterbury Plains. It is located near the southern end of Pegasus Bay, and is bounded to the east by the Pacific Ocean and to the south by the ancient volcanic complex of the Banks Peninsula. The Avon River / Ōtākaro winds through the centre of the city, with a large urban park along its banks. With the exception of the Port Hills, it is a relatively flat city, on an average about 20 m (66 ft) above sea level. Christchurch has a reputation for being an English city, with its architectural identity and nickname the 'Garden City' due to similarities with garden cities in England, but also has a historic Māori heritage. Christchurch has a temperate oceanic climate with moderate rainfall. The area of modern-day greater Christchurch was first inhabited by the historic Māori iwi Waitaha in the mid-thirteenth century. Waitaha, who occupied the swamplands with patchworks of marshland, were invaded by Kāti Māmoe in the sixteenth century, and then were absorbed by Kāi Tahu a century later. Ōtautahi was inhabited seasonally, and a major trading centre was established at Kaiapoi Pā. British colonial settlement began in the mid-nineteenth century. The First Four Ships were chartered by the Canterbury Association and brought the Canterbury Pilgrims from Britain to Lyttelton Harbour in 1850. It became a city by letters patent on 31 July 1856, making it officially the oldest established city in New Zealand. Christchurch was heavily industrialised in the early 20th century, with the opening of the Main South Line railway and the development of state housing causing rapid growth in the city's economy and population. Christchurch has strong cultural connections with its European elements and architectural identity. Christchurch is also home to a number of performing arts centres and academic institutions (including the University of Canterbury). Christchurch has hosted numerous international sporting events, notably the 1974 British Commonwealth Games at the purpose-built Queen Elizabeth II Park. The city has been recognised as an Antarctic gateway since 1901, and is nowadays one of the five Antarctic gateway cities hosting Antarctic support bases for several nations. Christchurch is served by the Christchurch Airport in Harewood, the country's second-busiest airport. The city suffered a series of earthquakes from September 2010, with the most destructive occurring on 22 February 2011, in which 185 people were killed and thousands of buildings across the city suffered severe damage, with many central city buildings collapsing, leading to ongoing recovery and rebuilding projects. Christchurch later became the site of the deadliest terrorist attack in New Zealand history, which targeted two mosques on 15 March 2019.

A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge (distance between the rails) narrower than 1,435 mm (4 ft 8+1⁄2 in) standard gauge. Most narrow-gauge railways are between 600 mm (1 ft 11+5⁄8 in) and 1,067 mm (3 ft 6 in). Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard: Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Australian states of Queensland, Western Australia and Tasmania have a 3 ft 6 in (1,067 mm) gauge, whereas Vietnam, Malaysia and Thailand have metre-gauge railways. Narrow-gauge trams, particularly metre-gauge, are common in Europe. Non-industrial, narrow-gauge mountain railways are (or were) common in the Rocky Mountains of the United States and the Pacific Cordillera of Canada, Mexico, Switzerland, Bulgaria, the former Yugoslavia, Greece, and Costa Rica.

The Russo-Japanese War (8 February 1904 – 5 September 1905) was fought between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and the Korean Empire. The major land battles of the war were fought on the Liaodong Peninsula and near Mukden in Southern Manchuria, with naval battles taking place in the Yellow Sea and the Sea of Japan. At the end of the First Sino-Japanese War, the Treaty of Shimonoseki of 1895 had ceded the Liaodong Peninsula and Port Arthur to Japan before the Triple Intervention, in which Russia, Germany, and France forced Japan to relinquish its claim. Japan feared that Russia would impede its plans to establish a sphere of influence in mainland Asia, especially as Russia built the Trans-Siberian Railroad, began making inroads in Korea, and acquired a lease of the Liaodong Peninsula and Port Arthur from China in 1898. Japan signed the Anglo-Japanese Alliance in 1902, and began offering to recognize Russia's dominance in Manchuria in exchange for recognition of Korea as part of Japan's sphere of influence. However, this was rejected by Russia. After negotiations broke down, Japan opened hostilities in a surprise attack on the Russian Pacific Fleet at Port Arthur on 9 February [O.S. 27 January] 1904. Both sides declared war, and Japanese troops landed in Korea, crossed the Yalu River into Manchuria in May, and landed more forces on the Liaodong Peninsula. In August, the Japanese laid siege to Port Arthur, which eventually fell in January 1905. In March 1905, Japanese troops took Mukden, the Manchurian capital, after heavy fighting. The Russian Baltic Fleet, which had sailed over seven months and 18,000 nautical miles (33,000 km) from the Baltic Sea to reinforce its Pacific Fleet, arrived in the region in May and was intercepted and destroyed by the Japanese Combined Fleet at the Battle of Tsushima. The war was concluded with the Treaty of Portsmouth (5 September [O.S. 23 August] 1905), mediated by US president Theodore Roosevelt. The treaty recognized Japanese interests in Korea, and awarded to Japan Russia's lease on the Liaodong Peninsula, control of the Russian-built South Manchuria Railway, and the southern half of the island of Sakhalin (Karafuto). The complete military victory of an Asian and non-Western nation over a European and Western power surprised international observers, and transformed the global balance of power, with the Empire of Japan emerging as a great power and the Russian Empire declining in prestige among the European powers. Russia's incurrence of substantial casualties and losses for a cause which resulted in a humiliating defeat contributed to internal unrest culminating in the 1905 Russian Revolution, during which the Russian autocracy was forced to make concessions. More widely, however, Japan's win effectively damaged the credibility of European dominance across Asia.

World War I, or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. One of the deadliest conflicts in history, World War I resulted in an estimated 15 to 22 million deaths, including those in war crimes and genocides. The war also helped spread the Spanish flu pandemic. The conflict saw important developments in weaponry, including the first large-scale use of machine guns, artillery, aircraft, chemical weapons, and tanks.

The Nazi Party, officially the National Socialist German Workers' Party, was a far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party, existed from 1919 to 1920. The Nazi Party emerged from the extremist German nationalist, racist, and populist Freikorps paramilitary culture, which fought against communist uprisings in post–World War I Germany. The party was created to draw workers away from communism and into völkisch nationalism. Hitler stated while on trial for his role in the Beer Hall Putsch in February 1924 that "I have resolved to be the destroyer of Marxism", a statement which he later applied to those opposed to the Nazi Party in 1926, claiming "They tried to paralyze the one party that would have been able to give opposition to this Red pest." Initially, Nazi political strategy used socialist rhetoric to gain the support of the lower middle class whilst maintaining other views; that was later downplayed to gain the support of business leaders. By the 1930s, the antisemitic and anti-Marxist themes of the party became even further emphasized. The party had little popular support until the Great Depression, when worsening living standards and widespread unemployment drove Germans into political extremism.

Bulgaria, officially the Republic of Bulgaria, is a country in Southeastern Europe. It is situated on the eastern portion of the Balkans directly south of the Danube river and west of the Black Sea. Bulgaria is bordered by Greece and Turkey to the south, Serbia and North Macedonia to the west, and Romania across the Danube river to the north. It covers a territory of 110,994 square kilometres (42,855 sq mi), making it the tenth largest within the European Union and the sixteenth-largest country in Europe by area. Sofia is the nation's capital and largest city; other major cities include Plovdiv, Varna, and Burgas.

Gold is a chemical element; its chemical symbol is Au and atomic number 79. In its pure form, it is a bright-metallic-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactive chemical elements, being the second lowest in the reactivity series, with only platinum ranked as less reactive. Gold is solid under standard conditions.

The Holocaust, known in Hebrew as the Shoah, was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered around six million Jews across German-occupied Europe, approximately two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, Chełmno and Majdanek death camps in occupied Poland. Concurrent Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups, such as the Romani and Soviet POWs. The Nazis developed their ideology based on racism and pursuit of "living space", and seized power in early 1933. Meant to force all German Jews to emigrate, regardless of means, the regime passed anti-Jewish laws, encouraged violence, and orchestrated a nationwide pogrom known as Kristallnacht in November 1938. After Germany's invasion of Poland in September 1939, occupation authorities began to establish ghettos to segregate Jews. Following the June 1941 invasion of the Soviet Union, 1.5 to 2 million Jews were murdered by German forces and local collaborators. The Nazis first targeted Jewish Red Army POWs and male civilians, but quickly escalated to murdering Jewish women and children. By early 1942, following the Wannsee Conference presided by Reinhard Heydrich, the Nazis' Final Solution was implemented to murder all Jews in Europe. Some historians note that Adolf Hitler frequently communicated major policy decisions verbally to Heinrich Himmler rather than through written directives. Victims were deported to extermination camps where those who had survived the trip were gassed, while others were sent to forced labor camps where many died from starvation, abuse, exhaustion, or being used as test subjects in experiments. Property belonging to murdered Jews was redistributed to the German occupiers and other non-Jews. The murder rate was most intense during Operation Reinhard from March 1942 to November 1943. Although the majority of Holocaust victims died in 1942, the mass murders continued until the end of the war in 1945. Many Jewish survivors emigrated from Europe after the war. A few Holocaust perpetrators faced criminal trials. Billions of dollars in reparations have been paid, although falling short of the losses suffered by the European Jews. The Holocaust has also been commemorated in museums, memorials, and culture. It is considered to be the single deadliest genocide in human history, and has become central to Western historical consciousness as a symbol of the ultimate human evil.

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.

Pierre Jean Marie Laval (French: [pjɛʁ laval]; 28 June 1883 – 15 October 1945) was a French politician. He served as Prime Minister of France three times: 1931–1932 and 1935–1936 during the Third Republic, and 1942–1944 during Vichy France. After the war, Laval was tried as a Nazi collaborator and executed for treason. A socialist early in his life, Laval became a lawyer in 1909 and was famous for his defence of strikers, trade unionists and leftists from government prosecution. In 1914, he was elected to the Chamber of Deputies as a member of the French Section of the Workers' International (SFIO), and he remained committed to his pacifist convictions during the First World War. After his defeat in the 1919 election, Laval left the SFIO and became mayor of Aubervilliers. In 1924 he returned to the Chamber as an independent, and was elected to the Senate three years later. He also held a series of governmental positions, including Minister of Public Works, Minister of Justice and Minister of Labour. In 1931, Laval became prime minister, but his government fell only a year later. Laval joined the conservative government of Gaston Doumergue in 1934 and served as Minister of the Colonies and then Foreign Minister. In 1935, Laval again became prime minister. Seeking to contain Nazi Germany, he pursued foreign policies favourable to Italy and the Soviet Union, but his handling of the Abyssinia Crisis, which was widely denounced as appeasement of Benito Mussolini, prompted his resignation in 1936. After France's defeat by the blitzkrieg invasion of Nazi Germany, Laval, by this time a well-known fascist sympathizer, served in prominent roles in Philippe Pétain's Vichy France, first as the vice-president of the Council of Ministers from July 1940 to December 1940 and later as the head of government from April 1942 to August 1944. After the Liberation of France in 1944, Laval was imprisoned by the Germans. In April 1945, he fled to Spain but was soon extradited to France, where he was arrested by the French government. Laval was found guilty of plotting against the security of the state and of collaboration with the Nazis and was sentenced to death. After a thwarted suicide attempt, Laval was executed by firing squad in October 1945. Laval was a chain smoker, he was noted to have smoked 80 'tabac brun' each day.

John F. Kennedy International Airport is the primary international airport serving the New York metropolitan area. It is located on the southwestern shore of Long Island, in Queens, New York City, bordering Jamaica Bay. It is the busiest of the three airports in the New York airport system, the sixth-busiest airport in the United States.

Nearly 100 airlines operate from JFK Airport, with nonstop or direct flights to destinations on all six permanently inhabited continents.

USS Nevada (BB-36), the third United States Navy ship to be named after the 36th state, was the lead ship of the two Nevada-class battleships. Launched in 1914, Nevada was a leap forward in dreadnought technology; four of her new features would be included on almost every subsequent US battleship: triple gun turrets, oil in place of coal for fuel, geared steam turbines for greater range, and the "all or nothing" armor principle. These features made Nevada, alongside her sister ship Oklahoma, the first US Navy "standard-type" battleships.

The Ranger program was a series of uncrewed space missions by the United States in the 1960s whose objective was to obtain the first close-up images of the surface of the Moon. The Ranger spacecraft were designed to take images of the lunar surface, transmitting those images to Earth until the spacecraft were destroyed upon impact. A series of mishaps, however, led to the failure of the first six flights. At one point, the program was called "shoot and hope". Congress launched an investigation into "problems of management" at NASA Headquarters and Jet Propulsion Laboratory. After two reorganizations of the agencies, Ranger 7 successfully returned images in July 1964, followed by two more successful missions.

MV Darlwyne was a pleasure cruiser, a converted Royal Navy picket boat, that disappeared off the Cornish coast on 31 July 1966 with its complement of thirty-one. Twelve bodies and a few artefacts were later recovered, but the rest of the victims and the main body of the wreck were never found.

A rum ration was a daily amount of rum given to sailors aboard naval ships. The Royal Navy, alongside several Commonwealth navies, were best known for the practice. It was abolished in Britain on Black Tot Day in 1970 after concerns that the intake of strong alcohol would lead to unsteady hands when working machinery. The practice ended worldwide in 1990 when New Zealand was the last navy to abolish the practice.

The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which landed the first humans on the Moon in 1969. Apollo was conceived in 1960 in the Dwight D. Eisenhower presidency during Project Mercury and executed after Project Gemini. Apollo was later dedicated to President John F. Kennedy's national goal, "before this decade is out, of landing a man on the Moon and returning him safely to the Earth" in his address to the U.S. Congress on May 25, 1961.

The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011. Its official program name was carried over from the 1969 plan for the Space Transportation System (STS) of reusable spacecraft. Only the shuttle and supporting rockets were funded for development; a proposed nuclear lunar shuttle in the plan was canceled in 1972. It flew 135 missions and carried 355 astronauts from 16 countries, many on multiple trips.

The Discovery Program is a series of Solar System exploration missions funded by the U.S. National Aeronautics and Space Administration (NASA) through its Planetary Missions Program Office. The cost of each mission is capped at a lower level than missions from NASA's New Frontiers or Flagship Programs. As a result, Discovery missions tend to be more focused on a specific scientific goal rather than serving a general purpose.

Operation Banner was the operational name for the British Armed Forces' operation in Northern Ireland from 1969 to 2007, as part of the Troubles. It was the longest continuous deployment in British military history. The British Army was initially deployed, at the request of the unionist government of Northern Ireland, in response to the August 1969 riots. Its role was to support the Royal Ulster Constabulary (RUC) and to assert the authority of the British government in Northern Ireland. This involved counter-insurgency and supporting the police in carrying out internal security duties such as guarding key points, mounting checkpoints and patrols, carrying out raids and searches, riot control and bomb disposal. More than 300,000 soldiers served in Operation Banner. At the peak of the operation in the 1970s, about 21,000 British troops were deployed, most of them from Great Britain. As part of the operation, a new locally-recruited regiment was also formed: the Ulster Defence Regiment (UDR).
