December 24 in History

Year 502 (DII) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Avienus and Probus. The denomination 502 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Pope John IV (Latin: Ioannes IV; died 12 October 642) was the bishop of Rome from 24 December 640 to his death on 12 October 642. His election followed a four-month vacancy. He wrote to the clergy of Ireland and Scotland to tell them of the mistakes they were making with regard to the time of keeping Easter and condemned Monothelitism as heresy. According to sacred tradition, he created the Catholic Church in Croatia with Abbot Martin.

The Tang dynasty was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point of Chinese civilisation, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, surpassed that of the Han dynasty.

The Crusades were a series of military campaigns launched by the papacy between 1095 and 1291 against Muslim rulers for the recovery and defence of the Holy Land, as part of a wider crusading movement. The First Crusade was proclaimed by Pope Urban II at the Council of Clermont in November 1095—a call to arms for Christians to reconquer Jerusalem from the Muslims, with promises of spiritual reward. By this time, the papacy's position as head of the Catholic Church had strengthened, and earlier conflicts with secular rulers and wars on the frontiers of Western Christendom had prepared it for the direction of armed force in religious causes. The successes of the First Crusade led to the establishment of four Crusader states in the Levant, whose defence required further expeditions from Catholic Europe. The organisation of such large-scale campaigns demanded complex religious, social, and economic institutions, including crusade indulgences, military orders, and the taxation of clerical income. Over time, the crusading movement expanded to include campaigns against pagans, Christian dissidents, and other enemies of the papacy, promoted with similar spiritual rewards and continuing into the 18th century.

Pope Boniface VIII (Latin: Bonifacius PP. VIII, Italian: Bonifacio VIII; born Benedetto Caetani; c. 1230 – 11 October 1303) was head of the Catholic Church and leader of the Papal States from 24 December 1294 until his death in 1303. The Caetani family was of baronial origin with connections to the papacy. He succeeded Pope Celestine V, who had abdicated from the papal throne. Boniface spent his early pontificate abroad in diplomatic roles. Boniface VIII put forward some of the strongest claims of any pope to temporal as well as spiritual power. He involved himself often with foreign affairs, including in France, Sicily, Italy, and the First War of Scottish Independence. These views, and his chronic intervention in temporal affairs, led to many bitter quarrels with Albert I of Germany, Philip IV of France, and later Dante Alighieri, who expected the pope to soon arrive at the eighth circle of Hell in his Divine Comedy, among the simoniacs. Boniface systematized canon law by collecting it in a new volume, the Liber Sextus (1298), which continues to be important source material for canon lawyers. He established the first Catholic jubilee year to take place in Rome. Boniface had first entered into conflict with King Philip IV in 1296 when the latter sought to reinforce the nascent nation state by imposing taxes on the clergy and barring them from administration of the law. Boniface excommunicated Philip and all others who prevented French clergy from traveling to the Holy See, after which the king sent his troops to attack the pope's residence in Anagni on 7 September 1303 and capture him. Boniface was held for three days. He died a month afterwards. King Philip IV pressured Pope Clement V of the Avignon Papacy into staging a posthumous trial of Boniface. He was accused of heresy, but no verdict against him was delivered.

The Republic of Venice, officially the Most Serene Republic of Venice and traditionally known as La Serenissima, was a maritime republic with its capital in Venice, on the northeastern coast of Italy. Founded, according to tradition, in 697 by Paolo Lucio Anafesto, over the course of its 1,100 years of history it established itself as one of the major European commercial and naval powers. Initially extended in the Dogado area, during its history it annexed a large part of Northeast Italy, Istria, Dalmatia, the coasts of present-day Montenegro and Albania as well as numerous islands in the Adriatic and eastern Ionian seas. At the height of its expansion, between the 13th and 16th centuries, it also governed Crete, Cyprus, the Peloponnese, a number of Greek islands, as well as several cities and ports in the eastern Mediterranean.

The Maratha Empire, also referred to as the Maratha Confederacy, was an early modern polity in the Indian subcontinent. For most of its existence, it comprised the realms of the Peshwa and four major independent Maratha states under the nominal leadership of the former and nominal loyalty to the Chhatrapatis who were successors of Shivaji.

Kiritimati (Gilbertese pronunciation: [kiˈrɪsmæs]), also known as Christmas Island, is a Pacific Ocean atoll in the northern Line Islands. It is part of the Republic of Kiribati. The name is derived from the English word "Christmas" written in Gilbertese according to its phonology, in which the combination ti is pronounced /s/. Kiritimati is one of the world's largest atolls in terms of land area, consisting of about 312.38 km2 (120.61 sq mi) land area and a 328 km2 (127 sq mi) network of lagoons. The atoll is about 150 km (93 mi) in perimeter, while the lagoon shoreline extends for over 48 km (30 mi). Kiritimati comprises over 70% of the total land area of Kiribati, a country encompassing 33 Pacific atolls and islands. It lies 232 km (144 mi) north of the equator, 2,160 km (1,340 mi) south of Honolulu, and 5,360 km (3,330 mi) from San Francisco. Kiritimati is in the world's furthest forward time zone, UTC+14, and is therefore one of the first inhabited places on Earth to experience New Year's Day (see also Caroline Atoll, Kiribati). Although it lies 2,460 km (1,530 mi) east of the 180th meridian, the Republic of Kiribati realigned the International Date Line in 1995, placing Kiritimati to the west of the dateline. Nuclear tests were conducted on and around Kiritimati by the United Kingdom in the late 1950s, and by the United States in 1962. During these tests, the island was not evacuated, exposing the Kiribati residents and the British, New Zealand, and Fijian servicemen to nuclear radiation. The entire island is a wildlife sanctuary; access to five particularly sensitive areas is restricted.

The Plot of the rue Saint-Nicaise, also known as the machine infernale plot, was an assassination attempt on the First Consul of France, Napoleon Bonaparte, in Paris on 24 December 1800. It followed the conspiration des poignards of 10 October 1800 and was one of many Royalist and Catholic plots. Though Napoleon and his wife Joséphine narrowly escaped the attempt, five people were killed and twenty-six others were injured. The name of the machine infernale, the 'infernal device', was in reference to an episode during the sixteenth-century revolt against Spanish rule in Flanders. In 1585, during the Siege of Antwerp by the Spaniards, an Italian engineer in Spanish service made an explosive device from a barrel bound with iron hoops, filled with gunpowder, flammable materials and bullets, and set off by a blunderbuss triggered from a distance by a string. The Italian engineer called it la macchina infernale.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Northwestern Europe, off the coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland, with a population of over 69 million in 2024. The UK includes the island of Great Britain, the north-eastern part of the island of Ireland, and most of the smaller islands within the British Isles, covering 94,354 square miles (244,376 km2). It shares a land border with the Republic of Ireland and is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea, while maintaining sovereignty over the Crown Dependencies and the British Overseas Territories. The capital and largest city of England and the UK is London; Edinburgh, Cardiff and Belfast are the national capitals of Scotland, Wales and Northern Ireland, respectively.

"Silent Night" (German: "Stille Nacht, heilige Nacht") is a popular Christmas carol, composed in 1818 by Franz Xaver Gruber to lyrics by Joseph Mohr in Oberndorf bei Salzburg, Austria. It was declared an intangible cultural heritage by UNESCO in 2011. The song was first recorded in 1905 and has remained a popular success, appearing in films and multiple successful recordings, as well as being quoted in other musical compositions. It is one of the most recorded Christmas songs, with more than 137,000 known recordings.

The Crown Colony of Labuan was a British Crown colony on the island of Labuan – just off the northwestern shore of Borneo – established in 1848 after its acquisition from the Sultanate of Brunei in 1846. Apart from the main island, Labuan consists of six smaller islands: Burung, Daat, Kuraman, Papan, Rusukan Kecil, and Rusukan Besar. Labuan was expected by the British to be a second Singapore, but it did not fulfill its promise especially after the failure of its coal production that did not become fruitful, causing investors to withdraw their money, leaving all machinery equipment and Chinese workers that had entered the colony previously. The Chinese workers then began involving themselves in other businesses with many becoming chief traders of the island's produce of edible bird's nest, pearl, sago and camphor, with the main successful production later being the coconut, rubber and sago. World War II brought the invasion of Japanese forces which abruptly ended British administration. Subsequently, Labuan became the place where the Japanese commander in Borneo surrendered to the Allied forces, with the territory placed under a military administration before merging into the Crown Colony of North Borneo.

The Ku Klux Klan, sometimes referred to as the Klan, is an American white supremacist and far-right hate group. Historians widely identify it as one of the earliest terrorist groups in the United States, citing its organized use of violence and intimidation to influence political and social conditions, particularly in the post-Civil War South. Across its three major iterations, the Klan has operated as a secret society made up of multiple affiliated organizations that used threats, assaults, and killings to advance their aims. Over its various eras, its targets included African Americans, Jews, Catholics, and immigrants.

The Presidential Guard is a ceremonial infantry unit that guards the Tomb of the Unknown Soldier and the Presidential Mansion in Athens, Greece. The unit is distinguished as the last unit of Evzones in the Hellenic Army, and is closely associated with the traditional Evzone's uniform, which evolved from the clothes worn by the klephts in the Greek War of Independence. The most visible item of this uniform is the fustanella, a kilt-like garment. In 1868–1914 and 1937–1973, the guard also included a cavalry company.

Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-American electrical engineer and inventor who received hundreds of patents in fields related to radio and sonar between 1891 and 1936 (seven of them after his death). Fessenden pioneered developments in radio technology, including the foundations of amplitude modulation (AM) radio. His achievements included the first transmission of speech by radio (1900), and the first two-way radiotelegraphic communication across the Atlantic Ocean (1906). In 1932 he claimed that, in late 1906, he had also made the first radio broadcast of entertainment and music, although that claim has not been well documented. He did a majority of his work in the United States and, in addition to his Canadian citizenship, claimed U.S. citizenship through his American-born father.

The Italian Hall disaster (sometimes referred to as the 1913 Massacre) was a tragedy that occurred on Wednesday, December 24, 1913, at Italian Hall in Calumet, Michigan, United States. Seventy-three people—mostly striking mine workers and their families—were crushed to death in a stampede when someone falsely shouted "fire" at a crowded Christmas party.

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.

In the immediate aftermath of World War I, the region of Međimurje was occupied by forces loyal to the National Council of the State of Slovenes, Croats and Serbs, one of the predecessor states to the Kingdom of Yugoslavia, in November and December 1918. Predominantly inhabited by Croats, this territory was a part of the Kingdom of Hungary until it was captured by Yugoslav forces. The Paris Peace Conference (1919–1920) awarded the region to Yugoslavia, which annexed the territory. The campaign to capture Međimurje began in November 1918, ostensibly in response to Hungarian actions against a revolt by the population of Međimurje. Major Ivan Tomašević led a 300-strong force that was routed by Hungarian forces near Čakovec, the region's largest town. Pleas for military help from the Royal Serbian Army and the French Armée d'Orient were rebuffed due to obligations assumed under the Armistice of Belgrade between the Entente Powers and Hungary that defined the Drava River as the line of Hungarian control in the area. The National Council mounted a new effort on 24 December, sending a 3,000-strong force made up by Slovene volunteers and much of the Royal Croatian Home Guard. Major Dragutin Perko planned the second incursion into Međimurje in greater detail, and he later commanded a large part of the attacking forces. Međimurje was captured on 24 December without resistance from the Hungarian garrison. Perko was appointed its administrator, and the region was declared a part of the Kingdom of Serbs, Croats and Slovenes with a reference to the principle of self-determination. The Paris Peace Conference later confirmed the region's accession.

General Gabriele D'Annunzio, Prince of Montenevoso (12 March 1863 – 1 March 1938), sometimes written d'Annunzio as he used to sign himself, was an Italian poet, playwright, orator, journalist, aristocrat, and Royal Italian Army officer during World War I. He occupied a prominent place in Italian literature from 1889 to 1910 and in its political life from 1914 to 1924. He had the epithets il Profeta (The Prophet) and il Vate (The Poet): vate stems from the Latin vates, meaning a prophetic, divinatory, or inspirational poet. D'Annunzio was associated with the Decadent movement in his literary works, which interplayed closely with French symbolism and British aestheticism. Such works represented a turn against the naturalism of the preceding romantics and was both sensuous and mystical. He came under the influence of Friedrich Nietzsche, which would find outlets in his literary and later political contributions. His affairs with several women, including Eleonora Duse and Luisa Casati, received public attention. In his politics, which evolved many times, he associated himself with socialism and the progressivist views of the political left, responding to the illiberal and reactionary policies of Luigi Pelloux, as well as with the Historical Far Left. During World War I, D'Annunzio's image in Italy transformed from literary figure to national war hero. He was associated with the elite Arditi storm troops of the Italian Army and took part in actions such as the Flight over Vienna. As part of an Italian nationalist reaction against the Paris Peace Conference of 1919, he set up the short-lived Italian Regency of Carnaro in Fiume with himself as Duce. The Charter of Carnaro made music the fundamental principle of the state, which was corporatist in nature. Although D'Annunzio later preached nationalism and never called himself a fascist, he has been credited with partially inventing Italian fascism, as both his ideas and his aesthetics were an influence upon Benito Mussolini. At the same time, he was an influence on Italian socialists and an early inspiration to the first phase of the Italian resistance movement to fascism.

Albania, officially the Republic of Albania, is a country in Southeastern Europe. It is located in the Balkans, on the Adriatic and Ionian Seas within the Mediterranean Sea, and shares land borders with Montenegro to the northwest, Kosovo to the northeast, North Macedonia to the east and Greece to the south. With an area of 28,748 km2 (11,100 sq mi), it has a varied range of climatic, geological, hydrological and morphological conditions. Landscapes range from rugged snow-capped mountains in the Albanian Alps and the Korab, Skanderbeg, Pindus and Ceraunian Mountains, to fertile lowland plains extending from the Adriatic and Ionian sea coasts. Tirana is the capital and largest city, followed by Durrës, Vlorë, and Shkodër. Albania was inhabited by several Illyrian tribes, among them the Ardiaei, Bylliones, Dassaretii, Enchele, and Taulantians, with the Chaonians settled in the southwest. Several colonies were founded by the Ancient Greeks along the Albanian coast, most notably Apollonia. The Illyrians were the dominant power before the rise of Macedon. Following the Illyrian Wars, Albania was integrated into the Roman Empire and remained in the Byzantine Empire after its partition. During the Middle Ages, several Albanian principalities emerged, most notably the Principality of Arbanon, Kingdom of Albania, Principality of Albania and Albania Veneta. In the 15th century, Albania became a center of resistance against Ottoman expansion under the leadership of Gjergj Kastrioti Skanderbeg, whose military campaigns repelled Ottoman advances for over two decades. Although incorporated into the Ottoman Empire, Albania retained distinct cultural and social identities throughout four centuries of foreign rule, culminating in the Albanian Renaissance in the 19th century. Albania declared independence in 1912, followed by a turbulent 20th century marked by monarchy, foreign occupation during both World Wars, and a communist regime under Enver Hoxha. Since its independence in 1912, Albania has undergone many political changes, transitioning from a monarchy to a communist regime before becoming a sovereign parliamentary constitutional republic. Governed by a constitution prioritising the separation of powers, the political structure includes a parliament, a ceremonial president, a functional prime minister and a hierarchy of courts. Albania is a developing country with an upper-middle income economy driven by the service sector, with manufacturing and tourism—which attracted over 11 million visitors in 2024—playing significant roles. The illegal drug trade in Albania contributes around US$100 million to the economy per year. After the dissolution of its communist system, the country shifted from centralised planning to an open market economy. Citizens have universal health care access and free primary and secondary education. The country is an official candidate for membership in the European Union and has been negotiating accession since 2022.

Argentina, officially the Argentine Republic, is a country in the far south of South America. It covers an area of 2,780,085 km2 (1,073,397 mi2), making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. Argentina shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state divided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, the Southern Patagonian Ice Field, and a part of Antarctica.

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.

Kuching, officially the City of Kuching, is the capital and the most populous city in the state of Sarawak in Malaysia. It is also the capital of Kuching Division. The city is on the Sarawak River at the southwestern tip of Sarawak on the island of Borneo and covers an area of 431 km2 (166 sq mi) with a population of about 162,843 in the Kuching North administrative region and 351,815 in the Kuching South administrative region—a total of 514,658 people.

Benghazi is the second-largest city in Libya as well as the largest city in Cyrenaica, with an estimated population of 859,000 in 2023. Located on the Gulf of Sidra in the Mediterranean, Benghazi is also a major seaport.

Monarchism in France is the advocacy of restoring the monarchy in France, which was abolished after the 1870 defeat by Prussia, arguably before that in 1848 with the establishment of the French Second Republic. The French monarchist movements are roughly divided today into three groups:The Legitimists for the royal House of Bourbon, the Orléanists for the cadet branch of the House of Orléans, and the Bonapartists for the imperial House of Bonaparte

Dwight David "Ike" Eisenhower (born David Dwight Eisenhower; October 14, 1890 – March 28, 1969) was the 34th president of the United States, serving from 1953 to 1961. In his previous military career, he commanded the Allied Expeditionary Force during World War II, including in Operation Torch in North Africa and Operation Overlord on D-Day in Normandy. For his distinguished service in the U.S. Army, Eisenhower was honored with the five-star rank of General of the Army. Eisenhower graduated from West Point in 1915. During World War I, he was denied a request to serve in Europe and instead commanded a unit that trained tank crews. Between the wars he served in staff positions in the US and the Philippines, reaching the rank of brigadier general shortly before the entry of the US into World War II in 1941. After further promotion Eisenhower oversaw the Allied invasions of North Africa and Sicily before supervising the invasions of France and Germany. After the war ended in Europe, he served as military governor of the American-occupied zone of Germany (1945), as Army Chief of Staff (1945–1948), president of Columbia University (1948–1953), and as the first supreme commander of NATO (1951–1952). In 1952, Eisenhower entered the presidential race as a Republican, in part to block the presidential prospects of Senator Robert A. Taft, who opposed NATO and sought to undo the New Deal. Eisenhower won that year's election and the 1956 election in landslides, both times defeating Adlai Stevenson II. Eisenhower's main goals in office were to contain the spread of communism and reduce federal deficits. In 1953, Eisenhower considered using nuclear weapons to end the Korean War and may have threatened China with nuclear attack if an armistice was not reached quickly. China did agree and an armistice resulted, which remains in effect. His New Look policy of nuclear deterrence prioritized "inexpensive" nuclear weapons while reducing funding for expensive Army divisions. He continued Harry S. Truman's policy of recognizing Taiwan as the legitimate government of China, and he won congressional approval of the Formosa Resolution. His administration provided aid to help the French try to fight Vietnamese Communists in the First Indochina War. After the French left, he gave strong financial support to the new state of South Vietnam. Eisenhower supported regime-changing military coups in Iran and Guatemala orchestrated by his own administration. During the Suez Crisis of 1956, he condemned the Israeli, British, and French invasion of Egypt, and he forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. He deployed 15,000 soldiers during the 1958 Lebanon crisis. Near the end of his term, a summit meeting with the Soviet leader Nikita Khrushchev was cancelled when a US spy plane was shot down over the Soviet Union. Eisenhower approved the Bay of Pigs Invasion, which was left to John F. Kennedy to carry out. Eisenhower continued New Deal agencies and expanded Social Security. He covertly opposed Joseph McCarthy and contributed to the end of McCarthyism by openly invoking executive privilege. He signed the Civil Rights Act of 1957 and sent Army troops to enforce federal court orders which integrated schools in Little Rock, Arkansas. His administration undertook the development and construction of the Interstate Highway System, which remains the largest construction of roadways in American history. In 1957, following the Soviet launch of Sputnik, Eisenhower led the American response which included the creation of NASA and the establishment of a stronger, science-based education via the National Defense Education Act. The Soviet Union began to reinforce their own space program, escalating the Space Race. His two terms saw unprecedented economic prosperity except for a minor recession in 1958. In his farewell address, he expressed his concerns about the dangers of massive military spending, particularly deficit spending and government contracts to private military manufacturers, which he dubbed "the military–industrial complex". Historical evaluations of his presidency place him among the upper tier of US presidents.

SS Léopoldville was a 11,509 GRT passenger liner of the Compagnie Belge Maritime du Congo. She was converted for use as a troopship in the Second World War, and on 24 December 1944, while sailing between Southampton and Cherbourg, was torpedoed and sunk by the German submarine U-486. As a result, about 763 US soldiers and 15 officers of the ship's crew died. The crew had abandoned ship and left U.S. troops without proper evacuation orders.

Early Christmas morning, December 25, 1945, a fire destroyed the Sodder residence in Fayetteville, West Virginia, United States. At the time, it was occupied by George Sodder, his wife Jennie, and nine of their ten children. During the fire, George, Jennie, and four of the nine children escaped. The bodies of the other five children have never been found. The surviving Sodder family believed for the rest of their lives that the five missing children survived. The Sodders never rebuilt the house, instead converting the site into a memorial garden to the lost children. In the 1950s, as they came to doubt that the children had perished, the family put up a billboard at the site along State Route 16 with pictures of the five, offering a reward for information that would bring closure to the case. It remained standing until shortly after Jennie Sodder's death in 1989. In support of their belief that the children survived, the Sodders had pointed to a number of unusual circumstances before and during the fire. George disputed the Fayetteville fire department's finding that the blaze was electrical in origin, noting that he had recently had the house rewired and inspected. George and his wife suspected arson, leading to theories that the children had been taken by the Sicilian Mafia, perhaps in retaliation for George's outspoken criticism of the fascist government of his native Italy. State and federal efforts to investigate the case further in the early 1950s yielded no new information. The family did, however, later receive what may have been a picture of one of the boys as an adult during the 1960s. Their last surviving daughter, Sylvia, along with their grandchildren, continued to publicize the case in the 21st century in the media and online.

Libya, officially the State of Libya, is a country in the Maghreb region of North Africa. It borders the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest. With an area of almost 1.8 million km2 (700,000 sq mi), Libya is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world. The country claims 32,000 square kilometres of southeastern Algeria, south of the Libyan town of Ghat. The capital and largest city is Tripoli, located in the northwest and containing over a million of Libya's seven million people.

The Handley Page Victor is a British jet-powered strategic bomber developed and produced by Handley Page during the Cold War. It was the third and final 'V bomber' to be operated by the Royal Air Force (RAF), the other two being the Vickers Valiant and the Avro Vulcan.

The Tangiwai disaster was a railway accident that occurred at 10:21 p.m. on 24 December 1953, when a railway bridge over the Whangaehu River collapsed beneath an express passenger train at Tangiwai, North Island, New Zealand. The locomotive and the first six carriages derailed into the river, killing 151 people. The subsequent board of inquiry found that the accident was caused by the failure of the tephra dam holding back nearby Mount Ruapehu's Crater Lake, creating a rapid mudflow (lahar) in the Whangaehu River which destroyed one of the bridge piers at Tangiwai only minutes before the train reached the bridge. The volcano at Mount Ruapehu was not erupting at the time. The disaster remains New Zealand's worst rail accident.

From December 16 to 25, 1955, devastating flooding struck portions of California. It was caused by heavy rainfall and a levee break on the Feather River, and directly resulted in the deaths of 74 people, leaving damages of an estimated $150 million, one of the costliest floods ever recorded in California. The floods are commonly known as the Yuba–Sutter floods as there was extensive damage in Yuba and Sutter counties.

The Vietnam War was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam and South Vietnam and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct US military involvement escalated from 1965 until US forces were withdrawn in 1973. The fighting spilled into the Laotian and Cambodian civil wars, which ended with all three countries becoming communist in 1975.

Flying Tiger Line Flight 282 refers to the crash of a Lockheed Super Constellation aircraft, N6915C, shortly after takeoff from San Francisco International Airport in the early morning hours of Thursday, December 24, 1964.

The Canadair CL-44 was a Canadian turboprop airliner and cargo aircraft based on the Bristol Britannia that was developed and produced by Canadair in the late 1950s and early 1960s. Although innovative, only a small number of the aircraft were produced for the Royal Canadian Air Force (RCAF), and for commercial operators worldwide.

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. The Apollo program was conceived in 1960 in the Dwight D. Eisenhower presidency during Project Mercury and executed after Project Gemini. The Apollo program 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.

Allegheny Airlines Flight 736 was a regularly scheduled flight that crashed while attempting to land at Bradford Regional Airport in Bradford, Pennsylvania, on December 24, 1968. Of the 47 occupants on board, 20 were killed.

Umuahia is the capital city of Abia State in southeastern Nigeria. Umuahia is located along the rail road that lies between Port Harcourt to its south, and Enugu city to its north. Umuahia has a population of 359,230 according to the 2006 Nigerian census.

ETA, an acronym for Euskadi Ta Askatasuna, was an armed Basque nationalist and separatist organization active in Spain and France between 1959 and 2018. It was founded in 1959, during Francoist Spain, by a group of Basque nationalist students seeking to promote Basque identity and independence. Over time, ETA evolved into a clandestine paramilitary group that conducted a campaign of assassinations, bombings, and kidnappings primarily in Spain, particularly in the Basque Country and surrounding regions. ETA was considered the main organization of the Basque National Liberation Movement and played a central role in the Basque conflict, in which more than 850 people were killed, 2,600 were wounded, and nearly 90 were kidnapped. The group announced a definitive end to its armed activity in 2011 and formally dissolved in 2018.
