The Historians' History of the World

History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term history refers not to an academic field but to the past itself, times in the past, or to individual texts about the past.

Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a coherent narrative. Different schools of thought, such as positivism, the Annales school, Marxism, and postmodernism, have distinct methodological approaches.

History is a broad discipline encompassing many branches. Some focus on specific time periods, such as ancient history, while others concentrate on particular geographic regions, such as the history of Africa. Thematic categorizations include political history, military history, social history, and economic history. Branches associated with specific research methods and sources include quantitative history, comparative history, and oral history.

History emerged as a field of inquiry in antiquity to replace myth-infused narratives, with influential early traditions originating in Greece, China, and later in the Islamic world. Historical writing evolved throughout the ages and became increasingly professional, particularly during the 19th century, when a rigorous methodology and various academic institutions were established. History is related to many fields, including historiography, philosophy, education, and politics. (Full article...)

  View of Badajoz, across the Guadiana river from the foothills of the San Cristóbal heights, by Eugène-Ferdinand Buttura

  
  The Battle of the Gebora took place during the Peninsular War between Spanish and French armies on 19 February 1811, northwest of Badajoz, Spain. An outnumbered French force routed and nearly destroyed the Spanish Army of Extremadura.
  
  In a bid to help extricate Marshal André Masséna's army from its position in Portugal—mired in front of Lisbon's defensive Lines of Torres Vedras—Marshal Jean de Dieu Soult led part of the French Armée du Midi (Army of the South) from Andalusia into the neighbouring Spanish region of Extremadura and laid siege to the important fortress town of Badajoz. Viscount Wellington and the Spanish captain-general Pedro Caro y Sureda, 3rd Marquis de La Romana, sent a large Spanish army to raise the siege. La Romana, however, died before the army could depart, and command fell to General Gabriel de Mendizábal Iraeta. Supported by a small force of Portuguese cavalry, the Spaniards reached the town and camped on the nearby heights of San Cristóbal in early February 1811. (Full article...)

  Manchester Cenotaph in 2017, in its new location near the town hall; looking south

  
  Manchester Cenotaph is a war memorial in St Peter's Square, Manchester, England. Manchester was late in commissioning a First World War memorial compared with most British towns and cities; the city council did not convene a war memorial committee until 1922. The committee quickly achieved its target of raising £10,000 but finding a suitable location for the monument proved controversial. The preferred site in Albert Square would have required the removal and relocation of other statues and monuments, and was opposed by the city's artistic bodies. The next choice was Piccadilly Gardens, an area already identified for a possible art gallery and library; but in the interests of speedier delivery, the memorial committee settled on St Peter's Square. The area within the square had been had been purchased by the City Council in 1906, having been the site of the former St Peter's Church; whose sealed burial crypts remained with burials untouched and marked above ground by a memorial stone cross. Negotiations to remove these stalled so the construction of the cenotaph proceeded with the cross and burials in situ.
  
  Having picked a site, it was originally proposed to choose an architect by open competition, but the memorial committee was criticised in the local press when it reserved the right to overrule the judgement of the independent assessor. A sub-committee therefore approached Sir Edwin Lutyens directly, who produced, in a matter of weeks, a variation of his design for the Cenotaph in London. The memorial consists of a central cenotaph and a Stone of Remembrance flanked by twin obelisks, all features characteristic of Lutyens' works. Raised steps on either side of the Stone of Remembrance provided east-facing tribunes for the colour party in memorial parades. The cenotaph is topped by an effigy of a fallen soldier and decorated with relief carvings of the imperial crown, Manchester's coat of arms and inscriptions commemorating the dead. The structures, based on classical architecture, use abstract, ecumenical shapes rather than overt religious symbolism. In submitting the design, Lutyens stated that he envisaged the crypts and cross as remaining in place; as the cenotaph could stand on the foundations of the former church tower and the cross would serve to "consecrate the site", while there would be no explicit religious symbolism on the cenotaph itself.

  1946 emblem of the 509th Composite Group while part of the 58th Bombardment Wing, Very Heavy

  
  The 509th Composite Group (509 CG) was a unit of the United States Army Air Forces created during World War II and tasked with the operational deployment of nuclear weapons. It conducted the atomic bombings of Hiroshima and Nagasaki, Japan, in August 1945.
  
  The group was activated on 17 December 1944 at Wendover Army Air Field, Utah. It was commanded by Lieutenant Colonel Paul W. Tibbets. Because it contained flying squadrons equipped with Boeing B-29 Superfortress bombers, C-47 Skytrain, and C-54 Skymaster transport aircraft, the group was designated as a "composite", rather than a "bombardment" formation. It operated Silverplate B-29s, which were specially configured to enable them to carry nuclear weapons. (Full article...)

  The Battle of Khafji was the first major ground engagement of the Gulf War. It took place in and around the Saudi Arabian city of Khafji, from 29 January to 1 February 1991.
  
  Iraqi leader Saddam Hussein, who had already tried and failed to draw Coalition forces into costly ground engagements by shelling Saudi Arabian positions and oil storage tanks and firing Scud surface-to-surface missiles at Israel, ordered the invasion of Saudi Arabia from southern Kuwait. The 1st and 5th Mechanized Divisions and 3rd Armored Division were ordered to conduct a multi-pronged invasion toward Khafji, engaging Saudi Arabian, Kuwaiti, and U.S. forces along the coastline, with a supporting Iraqi commando force ordered to infiltrate further south by sea and harass the Coalition's rear.

  Lithograph of SMS Kaiser Friedrich III in 1900

  
  SMS Kaiser Friedrich III ("His Majesty's Ship Emperor Frederick III") was the lead ship of the Kaiser Friedrich III class of pre-dreadnought battleships. She was laid down at the Kaiserliche Werft in Wilhelmshaven in March 1895, launched in July 1896, and finished in October 1898. The ship was armed with a main battery of four 24-centimeter (9.4 in) guns in two twin gun turrets supported by a secondary battery of eighteen 15 cm (5.9 in) guns.
  
  Sea trials and modifications lasted more than a year, and once she entered active service in October 1899, the ship became the flagship of Prince Heinrich in I Squadron of the German Heimatflotte (Home Fleet). I Squadron was primarily occupied with training exercises throughout each year, and also made numerous trips to other European countries, particularly Great Britain and Sweden–Norway. In 1901, the ship was severely damaged after striking submerged rocks in the Baltic Sea; the incident contributed to design changes in later German battleships to make them more resistant to underwater damage.

  King Władysław II Jagiełło, detail of the Triptych of Our Lady of Sorrows in the Wawel Cathedral, Kraków

  
  Jogaila (Lithuanian: [jɔˈɡâːɪɫɐ] ^ⓘ; c. 1352/1362 – 1 June 1434), later Władysław II Jagiełło (Polish: [vwaˈdɨswaf jaˈɡʲɛwwɔ] ^ⓘ), was Grand Duke of Lithuania beginning in 1377 and starting in 1386, becoming King of Poland as well. As Grand Duke, he ruled Lithuania from 1377 to 1381 and from 1382 to 1401, at which time he became the Supreme Duke of Lithuania in exchange for naming his cousin Vytautas as the new Grand Duke. Władysław II initially served as King of Poland alongside his wife Jadwiga until her death in 1399, and then the sole ruler until his own death in 1434.
  
  Raised a Lithuanian polytheist, he converted to Catholicism in 1386 and baptized as Ladislaus (Polish: Władysław) in Kraków, married the young Queen Jadwiga, and was crowned King of Poland as Władysław II Jagiełło. In 1387, he converted Lithuania to Catholicism. His reign in Poland started in 1399, upon the death of Queen Jadwiga, lasted a further thirty-five years, and laid the foundation for the centuries-long Polish–Lithuanian union. He was a member of the Jagiellonian dynasty in Poland that bears his name and was previously also known as the Gediminid dynasty in the Grand Duchy of Lithuania. The dynasty ruled both states until 1572, and became one of the most influential dynasties in late medieval and early modern Europe. (Full article...)

  Leonard Cyril Deighton (/ˈdeɪtən/ DAY-tən; born 18 February 1929) is a British author. His publications have included cookery books and works on history, but he is best known for his spy novels.
  
  After completing his national service in the Royal Air Force, Deighton attended the Saint Martin's School of Art and the Royal College of Art in London; he graduated from the latter in 1955. He had several jobs before becoming a book and magazine illustrator and designed the cover for the first UK edition of Jack Kerouac's 1957 work On the Road. He also worked for a period in an advertising agency. During an extended holiday in France he wrote his first novel, The IPCRESS File, which was published in 1962 and was a critical and commercial success. He wrote several spy novels featuring the same central character, an unnamed working-class intelligence officer, cynical and tough. Between 1962 and 1966 Deighton was the food correspondent for The Observer and drew cookstrips—black-and-white graphic recipes with a limited number of words. A selection of these was collected and published in 1965 as Len Deighton's Action Cook Book, the first of five cookery books he wrote. Other topics of non-fiction include military history.

  Divizijski đeneral Dušan Trifunović commanded the Yugoslav 7th Army during the Axis invasion of Yugoslavia

  
  The 7th Army was a Royal Yugoslav Army formation raised prior to the German-led Axis invasion of Yugoslavia in April 1941, during World War II. It consisted of two divisions, two brigade-strength mountain detachments, and a brigade-strength infantry detachment. It formed part of the 1st Army Group, and was responsible for the defence of Yugoslavia's north-western frontier with Italy and Germany. Like all Yugoslav formations at the time, the 7th Army had serious deficiencies in both mobility and firepower.
  
  Despite concerns over a possible Axis invasion, orders for the general mobilisation of the Royal Yugoslav Army were not issued by the government until 3 April 1941, not to provoke Germany any further following the military coup d'état and precipitate war. When the invasion commenced on 6 April, the 7th Army was only partially mobilised, and on the first day the Germans seized several mountain passes and bridges over the Drava river. Slovene politicians formed a National Council of Slovenia with the intent of separating from Yugoslavia, and on the right flank of the 7th Army, the 4th Army was seriously weakened by Croat fifth column activities within its major units and higher headquarters from the outset. This alarmed the 7th Army commander, Divizijski đeneral Dušan Trifunović, but he was not permitted to withdraw from the border areas until the night of 7/8 April, and this was followed by the German capture of Maribor on 8 April as they continued to expand their bridgeheads, supported by the Luftwaffe.

  The Byzantine civil war of 1341–1347, sometimes referred to as the Second Palaiologan Civil War, was a conflict that broke out in the Byzantine Empire after the death of Andronikos III Palaiologos over the guardianship of his nine-year-old son and heir, John V Palaiologos. It pitted on the one hand Andronikos III's chief minister, John VI Kantakouzenos, and on the other a regency headed by the Empress-Dowager Anna of Savoy, the Patriarch of Constantinople John XIV Kalekas, and the megas doux Alexios Apokaukos. The war polarized Byzantine society along class lines, with the aristocracy backing Kantakouzenos and the lower and middle classes supporting the regency. To a lesser extent, the conflict acquired religious overtones; Byzantium was embroiled in the Hesychast controversy, and adherence to the mystical doctrine of Hesychasm was often equated with support for Kantakouzenos.
  
  As the chief aide and closest friend of Emperor Andronikos III, Kantakouzenos became regent for the underage John V upon Andronikos's death in June 1341. While Kantakouzenos was absent from Constantinople in September the same year, a coup d'état led by Alexios Apokaukos and the Patriarch John XIV secured the support of Empress Anna and established a new regency. In response, Kantakouzenos' army and supporters proclaimed him co-emperor in October, cementing the rift between himself and the new regency. The split immediately escalated into armed conflict.

  Michigan at a naval review off New York City, October 1912

  
  Two South Carolina-class battleships, also known as the Michigan class, were built for the United States Navy in the early twentieth century. Named South Carolina and Michigan, they were the first American dreadnoughts—powerful warships whose capabilities far outstripped those of the world's older battleships.
  
  At the turn of the twentieth century, the prevailing theory of naval combat was that battles would continue to be fought at relatively close range using many small, fast-firing guns. As such, each of the ships in the United States' previous Connecticut-class battleships carried many medium-sized weapons alongside four large guns. This paradigm was soon to be subverted, as American naval theorists proposed that a ship mounting a homogeneous battery of large guns would be more effective in battle. (Full article...)

  Fountain of Time in southeast Washington Park at the western edge of the Midway Plaisance

  
  Fountain of Time, or simply Time, is a sculpture by Lorado Taft, measuring 126 feet 10 inches (38.66 m) in length, situated at the western edge of the Midway Plaisance within Washington Park in Chicago, Illinois, in the United States. The sculpture is inspired by Henry Austin Dobson's poem "Paradox of Time". Its 100 figures passing before Father Time were created as a monument to the 100 years of peace between the United States and the United Kingdom following the Treaty of Ghent in 1814. Father Time faces the 100 from across a water basin. The fountain's water was turned on in 1920, and the sculpture was dedicated in 1922. It is a contributing structure to the Washington Park United States Registered Historic District, which is a National Register of Historic Places listing.
  
  Part of a larger beautification plan for the Midway Plaisance, Time was constructed from a new type of molded, steel-reinforced concrete that was claimed to be more durable and cheaper than alternatives. It was said to be the first of any kind of finished work of art made of concrete. Before the completion of Millennium Park in 2004, it was considered the most important art installation in the Chicago Park District. Time is one of several Chicago works of art funded by Benjamin Ferguson's trust fund. (Full article...)

  Maugham by Carl Van Vechten, 1934

  
  William Somerset Maugham CH (/mɔːm/ MAWM; 25 January 1874 – 16 December 1965) was an English writer, known for his plays, novels and short stories. Born in Paris, where he spent his first ten years, Maugham was schooled in England and went to a German university. He became a medical student in London and qualified as a physician in 1897. He never practised medicine, and became a full-time writer. His first novel, Liza of Lambeth (1897), a study of life in the slums, attracted attention, but it was as a playwright that he first achieved national celebrity. By 1908 he had four plays running at once in the West End of London. He wrote his 32nd and last play in 1933, after which he abandoned the theatre and concentrated on novels and short stories.
  
  Maugham's novels after Liza of Lambeth include Of Human Bondage (1915), The Moon and Sixpence (1919), The Painted Veil (1925), Cakes and Ale (1930) and The Razor's Edge (1944). His short stories were published in collections such as The Casuarina Tree (1926) and The Mixture as Before (1940); many of them have been adapted for radio, cinema and television. His great popularity and prodigious sales provoked adverse reactions from highbrow critics, many of whom sought to belittle him as merely competent. More recent assessments generally rank Of Human Bondage – a book with a large autobiographical element – as a masterpiece, and his short stories are widely held in high critical regard. Maugham's plain prose style became known for its lucidity, but his reliance on clichés attracted adverse critical comment. (Full article...)

  Jin dynasty (blue) and Song dynasty (orange) in 1141

  
  The Jin–Song Wars were a series of conflicts between the Jurchen-led Jin dynasty (1115–1234) and the Han-led Song dynasty (960–1279). In 1115, Jurchen tribes rebelled against their overlords, the Khitan-led Liao dynasty (916–1125), and declared the formation of the Jin. Allying with the Song against their common enemy the Liao dynasty, the Jin promised to cede to the Song the Sixteen Prefectures that had fallen under Liao control since 938. The Song agreed but the Jin's quick defeat of the Liao combined with Song military failures made the Jin reluctant to cede territory. After a series of negotiations that embittered both sides, the Jurchens attacked the Song in 1125, dispatching one army to Taiyuan and the other to Bianjing (modern Kaifeng), the Song capital.
  
  Surprised by news of an invasion, Song general Tong Guan retreated from Taiyuan, which was besieged and later captured. As the second Jin army approached the capital, Song emperor Huizong abdicated and fled south. Qinzong, his eldest son, was enthroned. The Jin dynasty laid siege to Kaifeng in 1126, but Qinzong negotiated their retreat from the capital by agreeing to a large annual indemnity. Qinzong reneged on the deal and ordered Song forces to defend the prefectures instead of fortifying the capital. The Jin resumed war and again besieged Kaifeng in 1127. They captured Qinzong, many members of the imperial family and high officials of the Song imperial court in an event known as the Jingkang Incident. This separated north and south China between Jin and Song. Remnants of the Song imperial family retreated to southern China and, after brief stays in several temporary capitals, eventually relocated to Lin'an (modern Hangzhou). The retreat divided the dynasty into two distinct periods, Northern Song and Southern Song. (Full article...)

  Battle of Stanhope Park

  
  The Weardale campaign, part of the First War of Scottish Independence, occurred during July and August 1327 in Weardale, England. A Scottish force under James, Lord of Douglas, and the earls of Moray and Mar faced an English army commanded by Roger, Lord Mortimer of Wigmore, accompanied by the newly crowned Edward III.
  
  In 1326 the English king Edward II was deposed by a rebellion led by his wife, Isabella, and her lover, Mortimer. England had been at war with Scotland for 30 years and the Scots took advantage of the chaotic situation to launch large raids into England. Seeing opposition to the Scots as a way of legitimising their position, Isabella and Mortimer prepared a large army to oppose them. In July 1327 this set off from York to trap the Scots and force them to battle. After two weeks of poor supplies and bad weather the English confronted the Scots when the latter deliberately gave away their position. (Full article...)

  Jackson in 2009

  
  General Sir Michael David Jackson, GCB, CBE, DSO, DL (21 March 1944 – 15 October 2024) was a British Army officer and one of its most high-profile generals since the Second World War. Originally commissioned into the Intelligence Corps in 1963, he transferred to the Parachute Regiment in 1970, with which he served two of his three tours of duty in Northern Ireland. On his first, he was present as an adjutant at the events of the Ballymurphy massacre (1971), where eleven unarmed civilians were shot dead by British troops, and then at Bloody Sunday in 1972, when British soldiers opened fire on unarmed protesters, killing fourteen. On his second, he was a company commander in the aftermath of the Warrenpoint ambush (1979), when the IRA killed 18 soldiers with two roadside bombs, the British Army's heaviest single loss of life during the Troubles. He was assigned to a staff post at the Ministry of Defence (MoD) in 1982 before assuming command of the 1st Battalion, Parachute Regiment, in 1984. Jackson was posted to Northern Ireland for the third time, as a brigade commander, in the early 1990s.
  
  In 1995–1996, Jackson served his first tour in the Balkans, where he commanded a multi-national division of the Implementation Force. Following a staff job in the UK, he was appointed commander of NATO's Allied Rapid Reaction Corps (ARRC) in 1997. He returned to the Balkans with the ARRC during the Kosovo War, during which he famously refused to obey an order from American General Wesley Clark, his immediate superior in the NATO chain of command, to block the runways of Pristina Airport and isolate the Russian contingent that was positioned there. He reportedly told Clark, "I'm not going to start the Third World War for you". The incident attracted controversy, particularly in the United States, and earned Jackson the nickname "Macho Jacko" in the British tabloid press. Jackson established a working relationship with the Russian general commanding the detachment at Pristina, giving him a bottle of whisky, of which Jackson was known to be fond, and providing the Russians with the protection of a squad of British soldiers, commanded by his son, Mark.

Fermi in 1943

Enrico Fermi (Italian: [enˈriːko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian and naturalized American physicist, renowned for being the creator of the world's first artificial nuclear reactor, the Chicago Pile-1, and a member of the Manhattan Project. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of very few physicists to excel in both theoretical and experimental physics. Fermi was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and for the discovery of transuranium elements. With his colleagues, Fermi filed several patents related to the use of nuclear power, all of which were taken over by the US government. He made significant contributions to the development of statistical mechanics, quantum theory, and nuclear and particle physics.

Fermi's first major contribution involved the field of statistical mechanics. After Wolfgang Pauli formulated his exclusion principle in 1925, Fermi followed with a paper in which he applied the principle to an ideal gas, employing a statistical formulation now known as Fermi–Dirac statistics. Today, particles that obey the exclusion principle are called "fermions". Pauli later postulated the existence of an uncharged invisible particle emitted along with an electron during beta decay, to satisfy the law of conservation of energy. Fermi took up this idea, developing a model that incorporated the postulated particle, which he named the "neutrino". His theory, later referred to as Fermi's interaction and now called weak interaction, described one of the four fundamental interactions in nature. Through experiments inducing radioactivity with the recently discovered neutron, Fermi discovered that slow neutrons were more easily captured by atomic nuclei than fast ones, and he developed the Fermi age equation to describe this. After bombarding thorium and uranium with slow neutrons, he concluded that he had created new elements. Although he was awarded the Nobel Prize for this discovery, the new elements were later revealed to be nuclear fission products. (Full article...)
