History by Frederick Dielman

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, politics, and archaeology. (Full article...)

  The farthing (derived from the Old English feorthing, a fourth part) was a British coin worth a quarter of an old penny (1⁄960 of a pound sterling). This is the equivalent of around 1⁄10 of a new penny. It ceased to be struck after 1956 and was demonetised from 1 January 1961.
  
  The British farthing is a continuation of the English farthing, struck by English monarchs prior to the Act of Union 1707, which unified the crowns of England and Scotland into the Kingdom of Great Britain. Only pattern farthings were struck under Queen Anne as there was a glut of farthings from previous reigns. The coin was struck intermittently under George I and George II, but by the reign of George III, counterfeits were so prevalent the Royal Mint ceased striking copper coinage after 1775. The next farthings were the first struck by steam power, in 1799 by Matthew Boulton at his Soho Mint under licence. Boulton coined more in 1806, and the Royal Mint resumed production in 1821. The farthing was struck fairly regularly under George IV and William IV. By then it carried a scaled-down version of the penny's design, and would continue to mirror the penny and halfpenny until after 1936. (Full article...)

  No. 38 Squadron was a Royal Australian Air Force (RAAF) transport and training unit active between 1943 and 2018. It was formed on 15 September 1943 and saw service during World War II transporting supplies and personnel between Australia and the combat zones in New Guinea and Borneo, using Douglas Dakota aircraft. Following the war, the squadron conducted regular courier flights between Australia and Japan in 1947 and 1948. No. 38 Squadron was deployed to Singapore from 1950 to 1952, supplying Commonwealth forces engaged in the Malayan Emergency and undertaking courier flights across Asia. In 1954 it became responsible for training RAAF personnel to operate Dakotas.
  
  After being re-equipped with de Havilland Canada DHC-4 Caribou in 1964, No. 38 Squadron served as the RAAF's operational conversion unit for the type and also conducted transport tasks within Australia and its territories. Throughout Australia's involvement in the Vietnam War, it prepared aircrew for operational service with No. 35 Squadron, and maintained a detachment in Papua and New Guinea to provide pilots with experience flying in tropical conditions. A Caribou was deployed to Pakistan from 1975 to 1978 to support United Nations peacekeepers, and detachments were established within Australia during the 1980s to provide search and rescue capabilities and work with Australian Army units. From 1999 until 2001, a detachment was deployed to East Timor as part of the Australian-led peacekeeping force in the newly independent nation. No. 38 Squadron continued to operate Caribou after No. 35 Squadron was disbanded in 2000, though the age of the aircraft increasingly affected its operations. (Full article...)

  Philip I's portrait on the obverse of a tetradrachm

  
  Philip I Epiphanes Philadelphus (Ancient Greek: Φίλιππος Ἐπιφανής Φιλάδελφος; between 124 and 109 BC–83 or 75 BC) was a Hellenistic Seleucid monarch who reigned as the king of Syria from 94 to either 83 or 75 BC. He was a son of King Antiochus VIII. He ascended the throne after the murder of his elder brother Seleucus VI, becoming king with his twin brother Antiochus XI. In 93 BC Antiochus XI took the Syrian capital Antioch from their cousin, Antiochus X. Antiochus XI became the senior king, and Philip I remained in a base in Cilicia. Antiochus X returned and killed Antiochus XI that year. Philip I then allied with his younger brother Demetrius III, who was based in Damascus. Antiochus X was probably killed in 88 BC. Demetrius III took the capital and besieged Philip I in Beroea (Aleppo), but the latter prevailed and took Antioch; their youngest brother Antiochus XII took Damascus.
  
  Philip I tried unsuccessfully to take Damascus for himself, after which he disappears from the historical record; there is no information about when or how he died. The Antiochenes, apparently refusing to accept Philip I's minor son Philip II as his successor, invited Tigranes II of Armenia to take the city. While the invasion of Tigranes II is traditionally dated to 83 BC, the year most scholars agree on for Philip I's death, the conflict may have taken place in 74 BC. Numismatic evidence and clues in ancient contemporary literature indicate that Philip I might have died in 75 BC, giving Antiochus X's widow Cleopatra Selene and her son Antiochus XIII, who probably took control of the south following the death of Antiochus XII in 82 BC, a year of claiming the whole kingdom. Philip I initiated monetary reforms, and his coins remained in circulation until the Romans conquered Syria in 64 BC. Thereafter, Roman authorities in Syria continued to issue coins modeled on Philip I's coins, including his portrait, until 13 BC. (Full article...)

  Kapucínska Street, where passersby were assaulted during the riots

  
  
  The Partisan Congress riots were attacks on Jews in Bratislava and other cities and towns in the autonomous Slovak region of Czechoslovakia between 1 and 6 August 1946. Nineteen people were injured, four seriously, in Bratislava alone.
  
  After World War II in Europe ended in May 1945, former Slovak partisans were often appointed as national administrators of businesses that had been Aryanized, or confiscated, from Jews by the Axis client state known as the Slovak State, leading to conflict with Jews seeking to regain their property. This conflict sporadically erupted into attacks on Jews. Tensions between Jewish and non-Jewish Slovaks were exacerbated in May 1946 by the passage of an unpopular law that mandated the restitution of Aryanized property and businesses to their original owners. Both antisemitic leaflets and attacks on Jews—many of them initiated by former partisans—increased following the restitution law. (Full article...)

  Official portrait, 1945

  
  Ernest Joseph King (23 November 1878 – 25 June 1956) was a fleet admiral in the United States Navy who served as Commander in Chief, United States Fleet (COMINCH) and Chief of Naval Operations (CNO) during World War II. Franklin Delano Roosevelt appointed King to command global American strategy during World War II and he held supreme naval command in his unprecedented double capacity as COMINCH and CNO. He was the U.S. Navy's second-most senior officer in World War II after Fleet Admiral William D. Leahy, who served as Chief of Staff to the Commander in Chief. King commanded the United States Navy's operations, planning, and administration and was a member of the Joint Chiefs of Staff and Combined Chiefs of Staff.
  
  King graduated fourth in the United States Naval Academy class of 1901. He received his first command in 1914, of the destroyer USS Terry in the occupation of Veracruz. During World War I, he served on the staff of Vice Admiral Henry T. Mayo, the commander in chief of the Atlantic Fleet. After the war, King was the head of the Naval Postgraduate School and commanded submarine divisions. He directed the salvage of the submarine USS S-51, earning the first of his three Navy Distinguished Service Medals, and later that of the USS S-4. He qualified as a naval aviator in 1927, and was captain of the aircraft carrier USS Lexington. He then served as Chief of the Bureau of Aeronautics. Following a period on the Navy's General Board, he became commander in chief of the Atlantic Fleet in February 1941. (Full article...)

  Scale model of Kaga as originally designed

  
  The Tosa-class battleships (土佐型戦艦, Tosa-gata Senkan) were two dreadnoughts ordered as part of the "Eight-Eight" fleet for the Imperial Japanese Navy (IJN) during the early 1920s. The ships were larger versions of the preceding Nagato class, and carried an additional 41-centimeter (16.1 in) twin-gun turret. The design for the class served as a basis for the Amagi-class battlecruisers.
  
  Both ships were launched in late 1921, but the first ship, Tosa, was cancelled in accordance with the terms of the Washington Naval Treaty before it could be completed, and was used in experiments testing the effectiveness of its armor scheme before being scuttled in the Bungo Channel. The hull of the second ship, Kaga, was converted into an aircraft carrier of the same name. The carrier supported Japanese troops in China during the Second Sino-Japanese War of the late 1930s, and took part in the attack on Pearl Harbor on 7 December 1941 and the invasion of Rabaul in the Southwest Pacific in January 1942. The following month her aircraft participated in the combined carrier airstrike on Darwin, Australia, during the Dutch East Indies campaign. She was sunk during the Battle of Midway in 1942.

  Clare Grant Stevenson, AM, MBE (18 July 1903 – 22 October 1988) was the inaugural Director of the Women's Auxiliary Australian Air Force (WAAAF), from May 1941 to March 1946. She was described in 2001 as "the most significant woman in the history of the Air Force". Formed as a branch of the Royal Australian Air Force (RAAF) in March 1941, the WAAAF was the first and largest uniformed women's service in Australia during World War II, numbering more than 18,000 members by late 1944 and making up over thirty per cent of RAAF ground staff.
  
  Born and educated in Victoria, Stevenson was an executive with the Berlei company when she was appointed Director WAAAF. Initially ranked squadron officer, she rose to become group officer by April 1942. Stevenson resumed her civilian career following her discharge from the Air Force in 1946. Long active in adult education and social welfare, she helped form aid organisations including the Carers Association of New South Wales (now Carers NSW) after retiring from Berlei in 1960. Stevenson was appointed a Member of the Order of the British Empire and a Member of the Order of Australia for her services to the community and to female veterans. (Full article...)

  The 2nd Red Banner Army (Russian: 2-я Краснознамённая армия, romanized: 2-ya Krasnoznamennaya armiya) was a Soviet field army of World War II that served as part of the Far Eastern Front.
  
  The army was formed at Khabarovsk in the Soviet Far East in 1938 as the 2nd Army. After the Far Eastern Front was split in September that year it became the 2nd Independent Red Banner Army. When the front was reformed in June 1940, the army was redesignated as the 2nd Red Banner Army, stationed in the Blagoveshchensk area. It spent the bulk of World War II guarding the border in that area, sending formations to the Eastern Front while undergoing several reorganizations. In August 1945, the army fought in the Soviet invasion of Manchuria, capturing the Japanese fortified regions of Aihun and Sunwu adjacent to its sector of the border, and advancing into Manchuria to Qiqihar. The army was disbanded after the war in late 1945. (Full article...)

  Bahia sometime before its mid-1920s modernization, as indicated by its two funnels

  
  Bahia was the lead ship of a two-vessel class of cruisers built for Brazil by the British company Armstrong Whitworth. Crewmen mutinied in November 1910 aboard Bahia, Deodoro, Minas Geraes, and São Paulo, beginning the four-day Revolta da Chibata (Revolt of the Lash). Brazil's capital city of Rio de Janeiro was held hostage by the possibility of a naval bombardment, leading the government to give in to the rebel demands which included the abolition of flogging in the navy. During the First World War, Bahia and its sister ship Rio Grande do Sul were assigned to the Divisão Naval em Operações de Guerra (Naval Division in War Operations), the Brazilian Navy's main contribution in that conflict. The squadron was based in Sierra Leone and Dakar and escorted convoys through an area believed to be heavily patrolled by U-boats.
  
  Bahia was extensively modernized in the mid-1920s. It received three new Brown–Curtis turbine engines and six new Thornycroft boilers, and it was converted from coal-burning to oil. The refit resulted in a striking aesthetic change, with the exhaust being trunked into three funnels instead of two. The armament was also modified, adding three 20 mm (0.79 in) Madsen autocannons, a 7 mm (0.28 in) Hotchkiss machine gun, and four 533 mm (21.0 in) torpedo tubes. In the 1930s, it served with government forces during multiple revolutions. (Full article...)

  Sir Thomas Erpingham's effigy (possibly taken from his tomb) in the Erpingham Gate, Norwich

  
  Sir Thomas Erpingham (c. 1357 – 27 June 1428) was an English soldier and administrator who loyally served three generations of the House of Lancaster, including Henry IV and Henry V, and whose military career spanned four decades. After the Lancastrian usurpation of the English throne in 1399, his career in their service was transformed as he rose to national prominence, and through his access to royal patronage he acquired great wealth and influence.
  
  Erpingham was born in the English county of Norfolk, and knighted when a young man. During the reign of Richard II he served under the King's uncle John of Gaunt, Duke of Lancaster, in Spain and Scotland, and was with Gaunt's son Henry Bolingbroke on crusades in Lithuania, Prussia and the Holy Land. Erpingham accompanied Bolingbroke into exile in October 1398, and was with him when he landed at Ravenspur in July 1399 to reclaim his inheritance as Duke of Lancaster, after his lands had been forfeited by Richard. Bolingbroke rewarded Erpingham by appointing him as constable of Dover Castle and warden of the Cinque Ports, and after ascending the throne as Henry IV he made him chamberlain of the royal household. Erpingham later helped to suppress the Epiphany Rising and was appointed guardian of Henry's second son Thomas. He was a member of the Privy Council, acting at one point as marshal of England. He attempted to have Henry le Despenser, the anti-Lancastrian bishop of Norwich, impeached as a rebel. (Full article...)

  Japanese transport under aerial attack in the Bismarck Sea, 3 March 1943

  
  The Battle of the Bismarck Sea (2–4 March 1943) took place in the South West Pacific Area (SWPA) during World War II when aircraft of the U.S. Fifth Air Force and the Royal Australian Air Force (RAAF) attacked a Japanese convoy carrying troops to Lae, New Guinea, as part of Operation 81. Most of the Japanese task force was destroyed, and Japanese troop losses were heavy.
  
  The Japanese convoy was a result of a Japanese Imperial General Headquarters decision in December 1942 to reinforce their position in the South West Pacific theatre. A plan was devised to move some 6,900 troops from Rabaul directly to Lae. The plan was understood to be risky, because Allied air power in the area was strong, but the Japanese decided to proceed because otherwise, the troops would have to be landed a considerable distance away and march through inhospitable swamp, mountain, and jungle terrain without roads before reaching their destination. On 28 February 1943, the convoy – comprising eight destroyers and eight troop transports with an escort of about 100 fighter aircraft – set out from Simpson Harbour in Rabaul. (Full article...)

  The Augustus of Prima Porta

  
  Augustus (born Gaius Octavius; 23 September 63 BC – 19 August AD 14), also known as Octavian (Latin: Octavianus), was the founder of the Roman Empire and the first Roman emperor from 27 BC until his death in AD 14. The reign of Augustus initiated an imperial cult and an era of imperial peace (the Pax Romana or Pax Augusta) when the Roman world was largely free of armed conflict. The principate, a style of government in which the emperor showed nominal deference to the Senate, was established during his reign and lasted until the Crisis of the Third Century.
  
  Octavian was born into an equestrian branch of the gens Octavia. Octavian's great-uncle, the dictator Julius Caesar, named him as his primary heir in his will, and after Caesar's assassination in 44 BC, Octavian inherited his estate and assumed his name. He fought for the loyalty of Caesar's legions. He was made a senator during a state emergency and seized power by marching on Rome in 43 BC, becoming its youngest elected consul. He, Mark Antony, and Marcus Lepidus formed a triumvirate regime with legally sanctioned powers to outlaw and oppose Caesar's assassins and their allies. Following their victory at the Battle of Philippi in 42 BC, the triumvirate divided the Roman Republic among themselves and ruled as de facto oligarchs. Competing ambitions eventually tore their alliance apart; Octavian had Lepidus exiled in 36 BC for opposing him in Sicily, while Marcus Agrippa, Octavian's naval commander, defeated Antony in Greece at the Battle of Actium in 31 BC. Antony and his wife Cleopatra, the Ptolemaic queen of Egypt, killed themselves during Octavian's invasion of Egypt, which then became Octavian's personal property. (Full article...)

  Oslyabya leaving Bizerte, French Tunisia, 1903

  
  Oslyabya (Russian: Ослябя) was the second of the three Peresvet-class second-class pre-dreadnought battleships built for the Imperial Russian Navy at the end of the nineteenth century, although construction delays meant that she was the last to be completed. The ship was part of the Second Pacific Squadron sent to the Far East during the Russo-Japanese War of 1904–05, and served as the flagship of Rear Admiral Baron Dmitry von Fölkersam. Oslyabya was sunk on 27 May 1905 at the Battle of Tsushima, and was the first all-steel battleship to be sunk by naval gunfire alone. Sources differ on the exact number of casualties, but over half her crew went down with the ship. (Full article...)

  Federal Building and U.S. Courthouse, Milwaukee, Wisconsin

  
  United States of America v. Progressive, Inc., Erwin Knoll, Samuel Day, Jr., and Howard Morland, 467 F. Supp. 990 (W.D. Wis. 1979), was a lawsuit brought against The Progressive magazine by the United States Department of Energy (DOE) in 1979. A temporary injunction was granted against The Progressive to prevent the publication of an article written by activist Howard Morland that purported to reveal the "secret" of the hydrogen bomb. Though the information had been compiled from publicly available sources, the DOE claimed that it fell under the "born secret" clause of the Atomic Energy Act of 1954.
  
  Although the case was filed in the Western District of Wisconsin, the judge there recused himself as a friend of the magazine. The case was therefore brought before Judge Robert W. Warren, a judge in the Eastern District of Wisconsin. Because of the sensitive nature of information at stake in the trial, two separate hearings were conducted, one in public, and the other in camera. The defendants, Morland and the editors of The Progressive, would not accept security clearances, as they would have had to sign non-disclosure agreements that would have put restraints on their free speech (including, significantly, in written form), and so were not present at the in camera hearings. Their lawyers obtained clearances so that they could participate, but were forbidden from conveying anything they heard to their clients. (Full article...)

  Qantas Captain Lester Brain in the 1930s

  
  Lester Joseph Brain, AO, AFC (27 February 1903 – 30 June 1980) was a pioneer Australian aviator and airline executive. Born in New South Wales, he trained with the Royal Australian Air Force (RAAF) before joining Queensland and Northern Territory Aerial Services (Qantas) as a pilot in 1924. He was awarded the Air Force Cross in 1929, after locating the lost aircraft Kookaburra in northern Australia. Having risen to Chief Pilot at Qantas by 1930, he was appointed Flying Operations Manager in 1938. As a member of the RAAF reserve, Brain coordinated his airline's support for the Australian military during World War II. He earned a King's Commendation for his rescue efforts during an air raid on Broome, Western Australia, in 1942, and was promoted to wing commander in 1944.
  
  Seeing little prospect for advancement at Qantas once the war had ended, Brain left to join the fledgling government-owned domestic carrier Trans Australia Airlines (TAA) in June 1946. Appointed its first General Manager, he swiftly built up the organisation to the stage where it could commence scheduled operations later in the year. By the time he resigned in March 1955, TAA was firmly established as one half of the Commonwealth government's two-airline system. After his departure from TAA, Brain became Managing Director of de Havilland Aircraft in Sydney, before joining the board of East-West Airlines as a consultant in January 1961. He was appointed an Officer of the Order of Australia in January 1979 and died in June the following year, aged seventy-seven. (Full article...)

The monument comprises six square platforms topped by three circular platforms, and is decorated with 2,672 relief panels and 504 Buddha statues. The monument is both a shrine to the Lord Buddha and a place for Buddhist pilgrimage. Evidence suggests Borobudur was abandoned following the 14th-century decline of Buddhist and Hindu kingdoms in Java, and the Javanese conversion to Islam. The monument is a UNESCO World Heritage Site and is the most popular tourist attraction in the country.

Einstein in 1947

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist best known for developing the theory of relativity. Einstein also made important contributions to quantum theory. His mass–energy equivalence formula E = mc², which arises from special relativity, has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics for "his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".

Born as a subject to the Kingdom of Württemberg, part of the German Empire, Einstein moved to Switzerland in 1895, forsaking his citizenship the following year. In 1896, at the age of seventeen, he enrolled in the mathematics and physics teaching diploma program at the Swiss federal polytechnic school in Zurich, graduating in 1900. He acquired Swiss citizenship a year later, which he kept for the rest of his life, and afterwards secured a permanent position at the Swiss Patent Office in Bern. In 1905, he submitted a successful PhD dissertation to the University of Zurich. In 1914, he moved to Berlin to join the Prussian Academy of Sciences and the Humboldt University of Berlin, becoming director of the Kaiser Wilhelm Institute for Physics in 1917; he also became a Prussian and consequently also German citizen again. In 1933, while Einstein was visiting the United States, Adolf Hitler came to power in Germany. Horrified by the Nazi persecution of his fellow Jews, he decided to remain in the US, and was granted American citizenship in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential German nuclear weapons program and recommending that the US begin similar research, later carried out as the Manhattan Project. (Full article...)
