History by Frederick Dielman

History is the systematic study of the past. As an academic discipline, it analyzes and interprets evidence to construct narratives about what happened and explain why it happened, focusing primarily on the human past. 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 slightly different sense, the term history refers not to an academic field but to the past itself or to individual texts about the past.

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, social history, and economic history. Branches associated with specific research methods include quantitative history, comparative history, and oral history.

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 integrate the perspectives of several individual sources to develop a coherent narrative. Different schools of thought, such as positivism, the Annales school, Marxism, and postmodernism, have distinct methodological approaches.

History emerged as a field of inquiry in the ancient period to replace myth-infused narratives, with influential early traditions originating in Greece, China, and later also 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...)

  A XX Bomber Command B-29 Superfortress taking off from an airfield in India during June 1944

  
  Operation Boomerang was a partially successful air raid by the United States Army Air Forces' (USAAF) XX Bomber Command against oil refining facilities in Japanese-occupied Dutch East Indies during World War II. The attack took place on the night of 10/11 August 1944 and involved attempts to bomb an oil refinery at Palembang and lay mines to interdict the Musi River.
  
  The raid formed part of a series of attacks on Japanese-occupied cities in South East Asia that XX Bomber Command conducted as an adjunct to its primary mission of bombing Japan. The command raided the Japanese city of Nagasaki on the same night as Operation Boomerang. (Full article...)

  Illustration of the Battle of Inab by Jean Colombe from the Passages d'outremer by Sébastien Mamerot, c. 1473–1474

  
  The Second Crusade (1147–1150) was the second major crusade launched from Europe. The Second Crusade was started in response to the fall of the County of Edessa in 1144 to the forces of Zengi. The county had been founded during the First Crusade (1096–1099) by the future King Baldwin I of Jerusalem in 1098. While it was the first Crusader state to be founded, it was also the first to fall.
  
  The Second Crusade was announced by Pope Eugene III, and was led in the east by European kings Louis VII of France and Conrad III of Germany, with help from a number of other European nobles. The armies of the two kings marched separately across Europe. After crossing Byzantine territory into Anatolia, both armies were separately defeated by the Seljuk Turks. The main Western Christian source, Odo of Deuil, and Syriac Christian sources claim that the Byzantine Emperor Manuel I Komnenos secretly hindered the crusaders' progress, particularly in Anatolia, where he is alleged to have deliberately ordered Turks to attack them. However, this alleged sabotage of the Crusade by the Byzantines was likely fabricated by Odo, who saw the Empire as an obstacle; moreover, Emperor Manuel had no political reason to do so. Louis and Conrad reached Jerusalem in 1148, where the remnants of their armies participated in an ill-advised attack on Damascus that ended in their retreat. Crusader efforts were successful in Iberia, where several territories—including Lisbon, the future capital of the Portuguese Empire—were conquered. (Full article...)

  M4 Sherman tanks and infantrymen of the U.S. 4th Armored Division in Coutances

  
  Operation Cobra was an offensive launched by the First United States Army under Lieutenant General Omar Bradley seven weeks after the D-Day landings, during the Normandy campaign of World War II. The intention was to take advantage of the distraction of the Germans by the British and Canadian attacks around Caen in Operation Goodwood, and thereby break through the German defenses that were penning in their forces, while the Germans were unbalanced. Once a corridor had been created, the First Army would then be able to advance into Brittany, rolling up the German flanks once free of the constraints of the bocage country. After a slow start, the offensive gathered momentum and German resistance collapsed as scattered remnants of broken units fought to escape to the Seine. Lacking the resources to cope with the situation, the German response was ineffectual mainly due to the effect of Operation Bluecoat and the entire Normandy front soon collapsed. Operation Cobra, together with concurrent offensives by the British Second Army and the Canadian First Army, was decisive in securing an Allied victory in the Normandy campaign.
  
  Having been delayed several times by poor weather, Operation Cobra commenced on 25 July 1944, with a concentrated aerial bombardment from thousands of Allied aircraft. Supporting offensives had drawn the bulk of German armored reserves toward the British and Canadian sector and, coupled with the general lack of men and materiel available to the Germans, it was impossible for them to form successive lines of defense. Units of the U.S. VII Corps led the initial two-division assault, while other First U.S. Army corps mounted supporting attacks designed to pin German units in place. Progress was slow on the first day but opposition started to crumble once the defensive crust had been broken. By 27 July, most organized resistance had been overcome and the VII and VIII Corps advanced rapidly, isolating the Cotentin Peninsula. (Full article...)

  Winfield Scott Hancock (February 14, 1824 – February 9, 1886) was a United States Army officer and the Democratic nominee for President of the United States in 1880. He served with distinction in the Army for four decades, including service in the Mexican–American War and as a Union general in the American Civil War. Known to his Army as "Hancock the Superb," he was noted in particular for his personal leadership at the Battle of Gettysburg in 1863. His military service continued after the Civil War, as Hancock participated in the military Reconstruction of the South and the U.S.'s western expansion and war with the Native Americans at the Western frontier. This concluded with the Medicine Lodge Treaty. From 1881 to 1885 he was president of the Aztec Club of 1847 for veteran officers of the Mexican-American War.
  
  Hancock's reputation as a war hero at Gettysburg, combined with his status as a Unionist and supporter of states' rights, made him a potential presidential candidate. When the Democrats nominated him for president in 1880, he ran a strong campaign, but was narrowly defeated by Republican James A. Garfield. Hancock's last public service involved the oversight of President Ulysses S. Grant's funeral procession in 1885. (Full article...)

  HMS Bellerophon (centre) in 1827, Thomas Luny

  
  HMS Bellerophon, known to sailors as the "Billy Ruffian", was a ship of the line of the Royal Navy. A third-rate of 74 guns, she was launched in 1786. Bellerophon served during the French Revolutionary and Napoleonic Wars, mostly on blockades or convoy escort duties. She fought in three fleet actions: the Glorious First of June (1794), the Battle of the Nile (1798) and the Battle of Trafalgar (1805). While the ship was on blockade duty in 1815, Napoleon boarded Bellerophon so he could surrender to the ship's captain, ending 22 years of almost continuous war between Britain and France.
  
  Built at Frindsbury, near Rochester in Kent, Bellerophon was initially laid up in ordinary, briefly being commissioned during the Spanish and Russian Armaments. She entered service with the Channel Fleet on the outbreak of the French Revolutionary Wars in 1792, and took part in the Glorious First of June in 1794, the first major fleet action of the wars. Bellerophon narrowly escaped being captured by the French in 1795, when her squadron was nearly overrun by a more powerful French fleet at the First Battle of Groix, but the bold actions of the squadron's commander, Vice-Admiral Sir William Cornwallis, caused the French to retreat. She played a minor role in efforts to intercept a French invasion force bound for Ireland in 1797, and then joined the Mediterranean Fleet under Sir John Jervis. Detached to reinforce Rear-Admiral Sir Horatio Nelson's fleet in 1798, she took part in the decisive defeat of a French fleet at the Battle of the Nile, where she suffered severe damage and lost several officers while engaging the much larger French flagship Orient. She returned to England before being sent to the West Indies, where she spent the Peace of Amiens (1802–03) on cruises and convoy escort duty between the Caribbean and North America.

  Group Captain Ian McLachlan as Officer Commanding No. 73 Wing at Goodenough Island, New Guinea, preparing to vote in the Australian federal election, c. August 1943

  
  Air Vice Marshal Ian Dougald McLachlan, CB, CBE, DFC (23 July 1911 – 14 July 1991) was a senior commander in the Royal Australian Air Force (RAAF). Born in Melbourne, he was a cadet at the Royal Military College, Duntroon, before joining the Air Force in December 1930. After serving in instructional and general flying roles, he took command of No. 3 Squadron in December 1939, leading it into action in the Middle East less than a year later. Awarded the Distinguished Flying Cross, he returned to Australia in 1942 to command air bases in Canberra and Melbourne. The following year he was posted to the South West Pacific, where he led successively Nos. 71 and 73 Wings. Having been promoted to group captain, he took charge of Southern Area Command in 1944, and No. 81 Wing in the Dutch East Indies the following year.
  
  Raised to acting air commodore in 1946, McLachlan served as senior air staff officer for the British Commonwealth Air Group in Japan until 1948. After leading North-Eastern Area Command in 1951–53, he was appointed a Commander of the Order of the British Empire and posted to Britain, where he attended the Imperial Defence College. Promoted air vice marshal, he returned to Australia in 1957 as Air Officer Commanding Training Command; in this role he carried out two major reviews focussing on the RAAF's educational and command systems. He was Deputy Chief of the Air Staff from 1959 to 1961, and then Head of the Australian Joint Services Staff in Washington, D.C., until 1963. Appointed a Companion of the Order of the Bath in 1966, McLachlan's final post before retiring in 1968 was as Air Member for Supply and Equipment. He was a consultant to Northrop after leaving the RAAF, and lived in Darling Point, Sydney, until his death in 1991. (Full article...)

  A US soldier, Robert L. Witzig, with a 2.36-inch bazooka prepares to take aim at a North Korean tank during the Battle of Pyongtaek which took place after the Battle of Osan. On his right is Kenneth R. Shadrick, who was later reported as the first American killed in the Korean War.

  
  The Battle of Osan (Korean: 오산 전투) was the first engagement between the United States and North Korea during the Korean War. On July 5, 1950, Task Force Smith, an American task force of 540 infantry supported by an artillery battery, was moved to Osan, south of Seoul, the capital of South Korea, and was ordered to fight as a rearguard to delay the advancing North Korean forces while more US troops arrived to form a stronger defensive line to the south. The task force lacked both anti-tank guns and effective infantry anti-tank weapons and had been equipped with obsolete 2.36-inch (60 mm) rocket launchers and a few 57 mm recoilless rifles. Aside from a limited number of HEAT shells for the unit's 105 mm howitzers, crew-served weapons that could defeat T-34/85 tanks from the Soviet Union had not yet been distributed to the US Army forces in South Korea.
  
  A North Korean tank column equipped with ex-Soviet T-34/85 tanks overran the task force in the first encounter and continued its advance south. After the North Korean tank column had breached US lines, the task force opened fire on a force of some 5,000 North Korean infantry that were approaching its position, which held up their advance. North Korean troops eventually flanked and overwhelmed the US positions, and the rest of the task force retreated in disorder. (Full article...)

  The Song dynasty at its greatest extent in 1111

  
  The Song dynasty (/sʊŋ/) was an imperial dynasty of China that ruled from 960 to 1279. The dynasty was founded by Emperor Taizu of Song, who usurped the throne of the Later Zhou dynasty and went on to conquer the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China following attacks by the Jin dynasty, the Song was eventually conquered by the Mongol-led Yuan dynasty.
  
  The dynasty's history is divided into two periods: during the Northern Song (北宋; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now East China. The Southern Song (南宋; 1127–1279) comprise the period following the loss of control over the northern half of Song territory to the Jurchen-led Jin dynasty in the Jin–Song wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng in Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.

  SS Washingtonian was a refrigerated cargo ship launched in 1913 by the Maryland Steel of Sparrows Point, Maryland, near Baltimore, as one of eight sister ships for the American-Hawaiian Steamship Company. When completed, she was the largest cargo ship in the US registry. During the United States occupation of Veracruz in April 1914, Washingtonian was chartered by the United States Department of the Navy for service as a non-commissioned refrigerated supply ship for the US fleet stationed off the Mexican coast.
  
  In January 1915, after a little more than one year of service, Washingtonian collided with the schooner Elizabeth Palmer off the Delaware coast and sank in ten minutes with the loss of her $1,000,000 cargo of 10,000 long tons (10,200 t) of raw Hawaiian sugar. In the days after Washingtonian's sinking, the price of sugar in the United States increased almost nine percent, partly attributed to the loss of Washingtonian's cargo. Lying under about 100 feet (30 m) of water, Washingtonian's wreck is one of the most popular recreational dive sites on the eastern seaboard. (Full article...)

  Lombardy in 1522. The location of the battle is marked.

  
  The Battle of Bicocca or La Bicocca (Italian: Battaglia della Bicocca) was fought on 27 April 1522, during the Italian War of 1521–26. A combined French and Venetian force under Odet de Foix, Vicomte de Lautrec, was decisively defeated by an Imperial–Spanish and Papal army under the overall command of Prospero Colonna. Lautrec then withdrew from Lombardy, leaving the Duchy of Milan in Imperial hands.
  
  Having been driven from Milan by an Imperial advance in late 1521, Lautrec had regrouped, attempting to strike at Colonna's lines of communication. When the Swiss mercenaries in French service did not receive their pay, however, they demanded an immediate battle, and Lautrec was forced to attack Colonna's fortified position in the park of the Arcimboldi Villa Bicocca, north of Milan. The Swiss pikemen advanced over open fields under heavy artillery fire to assault the enemy positions, but were halted at a sunken road backed by earthworks. Having suffered massive casualties from the fire of Imperial-Spanish arquebusiers, the Swiss retreated. Meanwhile, an attempt by French cavalry to flank Colonna's position proved equally ineffective. The Swiss, unwilling to fight further, marched off to their cantons a few days later, and Lautrec retreated into Venetian territory with the remnants of his army. (Full article...)

  Charles Heaphy VC (1820 – 3 August 1881) was an English-born New Zealand explorer and recipient of the Victoria Cross (VC), the highest military award for gallantry "in the face of the enemy" that could be awarded to British and Empire forces at the time. He was the first soldier of the New Zealand armed forces to be awarded the VC. He was also a noted artist of the colonial period who created watercolours and sketches of early settler life in New Zealand.
  
  Born in England, Heaphy joined the New Zealand Company in 1839. He arrived in New Zealand later that year and was commissioned to make a visual record of the company's work which was used to advertise the country to potential English migrants. Much of the next 2+1⁄2 years was spent travelling around New Zealand and executing paintings of the land and its inhabitants. When his contract with the company ended in 1842, he lived in Nelson for several years and explored large parts of the West Coast. He later moved north to Auckland to take up employment as a surveyor. (Full article...)

  Charles Edward in 1933 as SA-Gruppenführer

  
  Charles Edward (Leopold Charles Edward George Albert; 19 July 1884 – 6 March 1954) was at various points in his life a British prince, a German duke, and a Nazi politician. He was the last ruling duke of Saxe-Coburg and Gotha, a state of the German Empire, from 30 July 1900 to 14 November 1918. He was later given multiple positions in the Nazi regime, including leader of the German Red Cross, and acted as an unofficial diplomat for the German government.
  
  Charles Edward's parents were Prince Leopold, Duke of Albany, and Princess Helen of Waldeck and Pyrmont. His paternal grandparents were Queen Victoria of the United Kingdom and Prince Albert of Saxe-Coburg and Gotha. Prince Leopold died before his son's birth. Charles Edward was born in Surrey, England, and brought up as a British prince. He was a sickly child who developed a close relationship with his grandmother and his only sibling, Alice. He was privately educated, including at Eton College. In 1899, Charles Edward was selected to succeed to the throne of Saxe-Coburg and Gotha because he was deemed young enough to be re-educated as a German. He moved to Germany at the age of 15. Between 1899 and 1905, he was put through various forms of education, guided by his cousin, German Emperor Wilhelm II. (Full article...)

  Captain James Newland c.1918

  
  James Ernest Newland, VC (22 August 1881 – 19 March 1949) was an Australian soldier, policeman and a recipient of the Victoria Cross, the highest decoration for gallantry "in the face of the enemy" that can be awarded to members of the British and Commonwealth armed forces. Newland was awarded the Victoria Cross following three separate actions in April 1917, during attacks against German forces retreating to the Hindenburg Line. While in command of a company, Newland successfully led his men in several assaults on German positions and repulsed subsequent counter-attacks.
  
  Born in the Victorian town of Highton, Newland joined the Australian military in 1899 and saw active service during the Second Boer War. He continued to serve in the Australian Army's permanent forces on his return to Australia, and completed several years' service in the artillery. Transferring to the militia in 1907, Newland became a police officer in Tasmania before re-joining the permanent forces in 1910. After the outbreak of the First World War, he was appointed to the Australian Imperial Force and was among the first wave of men to land at Gallipoli. In the following days, Newland was wounded and evacuated to Egypt where he was commissioned as a second lieutenant. (Full article...)

  SMS Kaiser

  
  The Kaiser class was a class of five dreadnought battleships that were built in Germany prior to World War I and served in the Kaiserliche Marine (Imperial Navy) during the war. They were the third class of German dreadnoughts, and the first to feature turbine engines and superfiring turrets. The five ships were Kaiser, Friedrich der Grosse, Kaiserin, Prinzregent Luitpold, and König Albert. As was usual for German battleships of the period, the Kaiser class mounted main guns that were smaller than those of their British rivals: 30.5 cm (12 in), compared to the 34.3 cm (13.5 in) guns of the British Orion class.
  
  All five ships saw action in the North Sea during the war; they served together as VI Division of III Battle Squadron. Four were present during the Battle of Jutland; König Albert was in dock at the time. Of the four ships that took part in the battle, only Kaiser was damaged, being struck by two heavy-caliber shells. The ships also took part in Operation Albion in the Baltic Sea; during the operation they were reorganized as IV Battle Squadron, under the command of Vice Admiral Wilhelm Souchon. (Full article...)

  Solidus of Glycerius marked:
  d·n· glycerius p·f· aug·

  
  Glycerius (died after 474) was Roman emperor of the West from 473 to 474. He served as comes domesticorum (commander of the palace guard) during the reign of Olybrius (r. 472), until Olybrius died in November 472. After a four-month interregnum, Glycerius was proclaimed as emperor in March 473 by Gundobad, the magister militum (master of soldiers) and power behind the throne. Very few of the events of his reign are known other than that an attempted invasion of Italy by the Visigoths was repelled by local commanders, diverting them to Gaul. Glycerius also prevented an invasion by the Ostrogoths through diplomacy, including a gift of 2,000 solidi.
  
  Glycerius was not recognized by the Eastern Roman emperor Leo I (r. 457–474), who instead nominated Julius Nepos (r. 474–475/480) as Western Emperor and sent him with an army to invade the Western Empire. Glycerius was without allies because Gundobad had abandoned him, and therefore was forced to abdicate on 24 June 474, and was succeeded by Nepos. He was appointed Bishop of Salona, which position he held until his death. He died, possibly in 480, and a nearly contemporaneous source blames him for the assassination of Nepos, but the records for this event are muddled. (Full article...)

  Edward Gibbon (1737–1794) was an English historian who published The History of the Decline and Fall of the Roman Empire in six volumes between 1776 and 1788. Born in Putney, Surrey, he became a voracious reader while being raised by his aunt, and was sent to study at Magdalen College, Oxford, and in Switzerland. Returning to England, in 1761 Gibbon published his first book, Essai sur l'Étude de la Littérature. This was well received, but Gibbon's next book was a failure. In the early 1770s Gibbon began writing his history of the Roman Empire, which was received with great praise.

  Finnish markka

  Banknote credit: Bank of Finland; photographed by Andrew Shiva

  The Finnish markka was the currency of Finland from 1860 to 2002. The currency was divided into 100 pennies and was first introduced by the Bank of Finland to replace the Russian ruble at a rate of four markkaa to one ruble. The markka was replaced by the euro on 1 January 2002 and ceased to be legal tender on 28 February later that year.
  
  This picture shows a 20-markka banknote issued in 1862, as part of the first issue of markka banknotes (1860 to 1862), for the Grand Duchy of Finland, then an autonomous part of the Russian Empire; 1862 was also the first year of issue for this particular denomination. The banknote's obverse depicts the coat of arms of Finland on a Russian double-headed eagle, and was personally signed by the director and the cashier of the Bank of Finland. The text on the obverse is in Swedish, whereas the reverse is primarily in Russian and Finnish.

  Alexander the Great (356–323 BC), the King of Macedonia, as depicted in a detail from the Alexander Mosaic. Originally from the House of the Faun in Pompeii and dated to c. 100 BC, the mosaic depicts a battle between the armies of Alexander the Great and Darius III of Persia. It is believed to be a copy of an early 3rd century BC Hellenistic painting, probably by Philoxenos of Eretria. The whole mosaic measures 2.72 × 5.13 m (8 ft 11 in × 16 ft 9 in).

Bust of Shen at the Beijing Ancient Observatory

Shen Kuo (Chinese: 沈括; 1031–1095) or Shen Gua, courtesy name Cunzhong (存中) and pseudonym Mengqi (now usually given as Mengxi) Weng (夢溪翁), was a Chinese polymath, scientist, and statesman of the Song dynasty (960–1279). Shen was a master in many fields of study including mathematics, optics, and horology. In his career as a civil servant, he became a finance minister, governmental state inspector, head official for the Bureau of Astronomy in the Song court, Assistant Minister of Imperial Hospitality, and also served as an academic chancellor. At court his political allegiance was to the Reformist faction known as the New Policies Group, headed by Chancellor Wang Anshi (1021–1085).

In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the pole star and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancers' compasses in regard to declination).
