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 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 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 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 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...)

  Barracuda bombers and Corsair fighters being armed on the flight deck of HMS Formidable during Operation Goodwood

  
  Operation Goodwood was a series of British carrier air raids conducted against the German battleship Tirpitz at her anchorage in Kaafjord in occupied Norway during late August 1944. It was the last of several attacks made by the Home Fleet during 1944 which sought to damage or sink Tirpitz and thereby eliminate the threat it posed to Allied shipping. Previous raids on Kaafjord conducted by Fleet Air Arm aircraft had involved only one air attack; in Operation Goodwood several attacks were made in a single week. The Royal Navy hoped that these raids would wear down the formidable German defences.
  
  The British fleet departed its base on 18 August and launched the first raid against Kaafjord on the morning of 22 August. The attack failed, and a small raid that evening inflicted little damage. Attacks were conducted on 24 and 29 August and were also failures. Tirpitz had been hit by two bombs during the raid on 24 August, but neither caused significant damage. British losses during Operation Goodwood were 17 aircraft to all causes, a frigate sunk by a submarine, and an escort carrier badly damaged. German forces suffered the loss of 12 aircraft and damage to 7 ships. (Full article...)

  A British Lancaster bomber over Kaafjord during Operation Paravane

  A British Lancaster bomber over Kaafjord during Operation Paravane

  
  Operation Paravane was a British air raid of World War II that inflicted heavy damage on the German battleship Tirpitz, at anchor in Kaafjord in the far north of German-occupied Norway. The attack was conducted on 15 September 1944 by 21 Royal Air Force heavy bombers, which flew from an airfield in the north of the Soviet Union. The battleship was struck by one bomb, and further damaged by several near misses. This damage rendered Tirpitz unfit for combat, and she could not be repaired as it was no longer possible for the Germans to sail her to a major port.
  
  The attack on 15 September followed a series of raids conducted against Tirpitz with limited success by Royal Navy carrier aircraft between April and August 1944, seeking to sink or disable the battleship at her anchorage, so that she no longer posed a threat to Allied convoys travelling to and from the Soviet Union. The first of these raids was successful, but the other attacks failed due to shortcomings with the Fleet Air Arm's strike aircraft and the formidable German defences. As a result, the task of attacking the battleship was transferred to the RAF's Bomber Command. Avro Lancaster bombers from the Command's two elite squadrons flew to their staging airfield in the Soviet Union on the night of 11/12 September, and attacked on 15 September using heavy bombs and air-dropped mines. All of the British aircraft returned to base, though one of the Lancasters later crashed during its flight back to the United Kingdom. (Full article...)

  Polish culture during World War II was suppressed by the occupying powers of Nazi Germany and the Soviet Union, both of whom were hostile to Poland's people and cultural heritage. Policies aimed at cultural genocide resulted in the deaths of thousands of scholars and artists, and the theft and destruction of innumerable cultural artifacts. ''The maltreatment of the Poles was one of many ways in which the Nazi and Soviet regimes had grown to resemble one another", wrote British historian Niall Ferguson.
  
  The occupiers looted and destroyed much of Poland's cultural and historical heritage while persecuting and murdering members of the Polish cultural elite. Most Polish schools were closed, and those that remained open saw their curricula altered significantly. (Full article...)

  The stolen helicopter, now on display at NASJRB Willow Grove

  
  On February 17, 1974, U.S. Army Private First Class Robert Kenneth Preston (1953–2009) took off in a stolen Bell UH-1B Iroquois "Huey" helicopter from Tipton Field, Maryland, and landed it on the South Lawn of the White House in a significant breach of security. Preston had enlisted in the Army to become a helicopter pilot. However, he did not graduate from the helicopter training course and lost his opportunity to attain the rank of warrant officer pilot. His enlistment bound him to serve four years in the Army, and he was sent to Fort Meade as a helicopter mechanic. Preston believed this situation was unfair and later said he stole the helicopter to show his skill as a pilot.
  
  Shortly after midnight, Preston, on leave, was returning to Tipton Field, south of Fort Meade. Thirty helicopters at the base were fueled and ready to fly; he took off in one without turning on its anti-collision lights or making the standard radio calls. The Maryland State Police were alerted. Preston flew southwest toward Washington, D.C., where he hovered close to the Lincoln Memorial and the Washington Monument and over the South Lawn of the White House. He then flew back toward Fort Meade with two Bell 206 JetRanger police helicopters and police cars in pursuit. After a chase over Maryland, he reversed course toward Washington again and entered the White House grounds. The Secret Service opened fire this time. Preston was lightly wounded, landed the helicopter, and was arrested and held in custody. (Full article...)

  Three RAAF F/A-18A Hornets in 2012

  
  The Royal Australian Air Force (RAAF) operated McDonnell Douglas F/A-18 Hornet fighter aircraft between 1984 and 2021. The Australian Government purchased 75 A and B variants of the F/A-18 in 1981 to replace the RAAF's Dassault Mirage III fighters. The Hornets entered service with the RAAF between 1984 and 1990. Four Hornets were destroyed in flying accidents during the late 1980s and early 1990s.
  
  RAAF Hornets were first sent on a combat deployment as part of the Australian contribution to the 2003 invasion of Iraq. During the invasion, 14 Hornets flew patrols over Iraq, as well as close air support sorties to assist coalition ground forces. RAAF F/A-18s also provided security for the American air base at Diego Garcia between late 2001 and early 2002, and have protected a number of high-profile events in Australia. Between 2015 and 2017 a detachment of Hornets was deployed to the Middle East and struck ISIL targets as part of Operation Okra. (Full article...)

  Jilu Assyrians crossing the Asadabad Pass towards Baqubah, 1918

  
  
  The Sayfo (Syriac: ܣܲܝܦܵܐ, lit. 'sword'), also known as the Seyfo or the Assyrian genocide, was the mass murder and deportation of Assyrian/Syriac Christians in southeastern Anatolia and Persia's Azerbaijan province by Ottoman forces and some Kurdish tribes during World War I.
  
  
  The Assyrians were divided into mutually antagonistic churches, including the Syriac Orthodox Church, the Assyrian Church of the East, and the Chaldean Catholic Church. Before World War I, they largely lived in mountainous and remote areas of the Ottoman Empire and Persia, some of which were effectively stateless. The Ottoman Empire's nineteenth-century centralization efforts led to increased violence and danger for the Assyrians. (Full article...)

  Logo for celebrations commemorating the 50th anniversary of the treaty in 2008

  
  The US–UK Mutual Defense Agreement, or the 1958 UK–US Mutual Defence Agreement, is a bilateral treaty between the United States and the United Kingdom on nuclear weapons co-operation. The treaty's full name is Agreement between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern Ireland for Cooperation on the uses of Atomic Energy for Mutual Defense Purposes. It allows the US and the UK to exchange nuclear materials, technology and information. The US has nuclear co-operation agreements with other countries, including France and other NATO countries, but this agreement is by far the most comprehensive. Because of the agreement's strategic value to Britain, Harold Macmillan (the Prime Minister who presided over the United Kingdom's entry into the agreement) called it "the Great Prize".
  
  The treaty was signed on 3 July 1958 after the Soviet Union had shocked the American public with the launch of Sputnik on 4 October 1957, and the British hydrogen bomb programme had successfully tested a thermonuclear device in the Operation Grapple test on 8 November. The special relationship proved mutually beneficial, both militarily and economically. Britain soon became dependent on the United States for its nuclear weapons since it agreed to limit their nuclear program with the agreement of shared technology. The treaty allowed American nuclear weapons to be supplied to Britain through Project E for use by the Royal Air Force and British Army of the Rhine until the early 1990s when the UK became fully independent in designing and manufacturing its own warheads.

  A U.S. Army 75 mm pack howitzer firing at close range at a Japanese position on Hill 260 in March 1944

  
  The Bougainville counterattack, also known as the Second Battle of Torokina, was an unsuccessful Japanese offensive against the Allied base at Cape Torokina on Bougainville Island during the Pacific Theater of World War II. The Japanese attack began on 8 March 1944 after months of preparation and was repulsed by United States Army forces in fighting which lasted until 25 March. The attack was hampered by inaccurate intelligence and poor planning and was pushed back by the well-prepared Allied defenders, who greatly outnumbered the Japanese force. The Japanese suffered severe casualties, while Allied losses were light.
  
  The goal of the offensive was to destroy the Allied beachhead, which accommodated three strategically important airfields. The Japanese mistakenly believed that their forces were about as large as the units deployed to defend the Allied positions. The Allies detected Japanese preparations for the attack shortly after they began in early 1944 and strengthened the base's defenses. None of the three Japanese forces which conducted the attack was able to penetrate far into the Allied perimeter, although there was intense fighting for several positions. (Full article...)

  This portrait was first published in 1885 and alleged to be a 1625 likeness of Standish, although its authenticity has never been proven.

  
  Myles Standish (c. 1584 – October 3, 1656) was an English military officer and colonist. He was hired as military adviser for Plymouth Colony in present-day Massachusetts, United States by the Pilgrims. Standish accompanied the Pilgrims on the ship Mayflower and played a leading role in the administration and defense of Plymouth Colony from its foundation in 1620. On February 17, 1621, the Plymouth Colony militia elected him as its first commander and continued to re-elect him to that position for the remainder of his life. Standish served at various times as an agent of Plymouth Colony on a return trip to England, as assistant governor of the colony, and as its treasurer.
  
  A defining characteristic of Standish's military leadership was his proclivity for preemptive action. He led at least two attacks or small skirmishes against Native Americans in a raid on the village of Nemasket and a conflict at Wessagusset Colony. During these actions, Standish exhibited skill as a soldier, but disturbed more moderate members of the colony due to his brutality toward Natives. (Full article...)

  William is depicted in the Bayeux Tapestry during the Battle of Hastings, lifting his helmet to show that he is still alive.

  
  William the Conqueror (c. 1028 – 9 September 1087), sometimes called William the Bastard, was the first Norman king of England (as William I), reigning from 1066 until his death. A descendant of Rollo, he was Duke of Normandy (as William II) from 1035 onward. By 1060, following a long struggle, his hold on Normandy was secure. In 1066, following the death of Edward the Confessor, William invaded England, leading a Franco-Norman army to victory over the Anglo-Saxon forces of Harold Godwinson at the Battle of Hastings, and suppressed subsequent English revolts in what has become known as the Norman Conquest. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands, and by difficulties with his eldest son, Robert Curthose.
  
  William was the son of the unmarried Duke Robert I of Normandy and his mistress Herleva. His illegitimate status and youth caused some difficulties for him after he succeeded his father, as did the anarchy which plagued the first years of his rule. During his childhood and adolescence, members of the Norman aristocracy battled each other, both for control of the child duke, and for their own ends. In 1047, William quashed a rebellion and began to establish his authority over the duchy, a process that was not complete until about 1060. His marriage in the 1050s to Matilda of Flanders provided him with a powerful ally in the neighbouring county of Flanders. By the time of his marriage, William was able to arrange the appointment of his supporters as bishops and abbots in the Norman church. His consolidation of power allowed him to expand his horizons, and he secured control of the neighbouring county of Maine by 1062. (Full article...)

  Occupation and partition of Yugoslavia in 1941. The Hungarian-occupied then annexed areas of Yugoslavia are in the north (Bačka and Baranja) and northwest (Međimurje and Prekmurje).

  
  During World War II, the Kingdom of Hungary engaged in the military occupation, then annexation, of the Bačka, Baranja, Međimurje and Prekmurje regions of the Kingdom of Yugoslavia. These territories had all been under Hungarian rule prior to 1920, and had been transferred to Yugoslavia as part of the post-World War I Treaty of Trianon. They now form part of several states: Yugoslav Bačka is now part of Vojvodina, an autonomous province of Serbia, Yugoslav Baranja and Međimurje are part of modern-day Croatia, and Yugoslav Prekmurje is part of modern-day Slovenia. The occupation began on 11 April 1941 when 80,000 Hungarian troops crossed the Yugoslav border in support of the German-led Axis invasion of Yugoslavia that had commenced five days earlier. There was some resistance to the Hungarian forces from Serb Chetnik irregulars, but the defences of the Royal Yugoslav Army had collapsed by this time. The Hungarian forces were indirectly aided by the local Volksdeutsche, the German minority, which had formed a militia and disarmed around 90,000 Yugoslav troops. Despite only sporadic resistance, Hungarian troops killed many civilians during these initial operations, including some Volksdeutsche. The government of the newly formed Axis puppet state, the Independent State of Croatia, subsequently consented to the Hungarian annexation of the Međimurje area, which dismayed the Croat population of the region.
  
  The occupation authorities immediately classified the population of Bačka and Baranja into those that had lived in those regions when they had last been under Hungarian rule in 1920 and the mostly Serb settlers who had arrived since the areas had been part of Yugoslavia. They then began herding thousands of local Serbs into concentration camps and expelled them to the Independent State of Croatia, Italian-occupied Montenegro, and the German-occupied territory of Serbia. Ultimately, tens of thousands of Serbs were deported from the occupied territories. This was followed by the implementation of a policy of "magyarisation" of the political, social and economic life of the occupied territories, which included the re-settlement of Hungarians and Székelys from other parts of Hungary. "Magyarisation" did not impact the Volksdeutsche, who received special status under Hungarian rule, and in Prekmurje the Hungarian authorities were more permissive towards ethnic Slovenes.

  Circa 1820

  
  Isaac Shelby (December 11, 1750 – July 18, 1826) was an American politician and military officer who was the first and fifth Governor of Kentucky and served in the state legislatures of Virginia and North Carolina. He also fought in Lord Dunmore's War, the American Revolutionary War, and the War of 1812. While governor, he led the Kentucky militia in the Battle of the Thames, an action that was rewarded with a Congressional Gold Medal. Counties in nine states, and several cities and military bases, have been named in his honor. His fondness for John Dickinson's "The Liberty Song" is believed to be the reason Kentucky adopted the state motto "United we stand, divided we fall".
  
  Issac Shelby's military service began when he served as second-in-command to his father at the Battle of Point Pleasant, the only major battle of Lord Dunmore's War. He gained the reputation of an expert woodsman and surveyor and spent the early part of the Revolutionary War gathering supplies for the Continental Army. Later in the war, he and John Sevier led expeditions over the Appalachian Mountains against the British forces in North Carolina. He played a pivotal role in the British defeat at the Battle of Kings Mountain. For his service, Shelby was presented with a ceremonial sword and a pair of pistols by the North Carolina legislature, and the nickname "Old Kings Mountain" followed him the rest of his life.

  A propaganda poster calling on Australians to avenge the sinking of Australian hospital ship Centaur by Japanese submarine I-177 in May 1943.

  
  There was considerable Axis naval activity in Australian waters during the Second World War, despite Australia being remote from the main battlefronts. German and Japanese warships and submarines entered Australian waters between 1940 and 1945 and attacked ships, ports and other targets. Among the best-known attacks are the sinking of HMAS Sydney by a German raider in November 1941, the bombing of Darwin by Japanese naval aircraft in February 1942, and the Japanese midget submarine attack on Sydney Harbour in May 1942. About 40 Allied merchant ships were damaged or sunk off the Australian coast by surface raiders, submarines and mines. Japanese submarines also shelled three Australian ports and submarine-based aircraft flew over several Australian capital cities.
  
  The Axis threat to Australia developed gradually and until 1942 was limited to sporadic attacks by German armed merchantmen. The level of Axis naval activity peaked in the first half of 1942 when Japanese submarines conducted anti-shipping patrols off Australia's coast, and Japanese naval aviation attacked several towns in northern Australia. The Japanese submarine offensive against Australia was renewed in the first half of 1943 but was broken off as the Allies pushed the Japanese onto the defensive. Few Axis naval vessels operated in Australian waters in 1944 and 1945, and those that did had only a limited impact. (Full article...)

  Bruce in 1930

  
  Stanley Melbourne Bruce, 1st Viscount Bruce of Melbourne (15 April 1883 – 25 August 1967) was an Australian politician, statesman and businessman who served as the eighth prime minister of Australia from 1923 to 1929. He held office as the leader of the Nationalist Party, having previously served as the treasurer of Australia from 1921 to 1923.
  
  Born into a briefly wealthy Melbourne family, Bruce studied at the University of Cambridge and played a leading role in his family's softgoods firm following the suicide of his father John Munro Bruce. He served on the front lines of the Gallipoli Campaign in World War I and returned to Australia wounded in 1917, becoming a spokesman for government recruitment efforts. He gained the attention of the Nationalist Party and prime minister Billy Hughes, who encouraged a political career. He was elected to the House of Representatives in 1918, becoming member of parliament (MP) for the seat of Flinders. He was appointed as treasurer in 1921, before replacing Hughes as prime minister in 1923. He established an anti-socialist coalition government with the agrarian Country Party, working closely with Country leader Earle Page in an arrangement that pioneered the modern Liberal–National coalition.

  A Medieval depiction of a fortification being assaulted

  
  The siege of Breteuil was the investment (surrounding) of the Norman town of Breteuil, held by partisans of Charles II, King of Navarre, by French forces between April and about 20 August 1356. It was interrupted on 5 July when a small English army commanded by Henry, Earl of Lancaster, relieved and resupplied the town. The French king, John II, attempted to bring Lancaster to battle with the much larger French royal army, but Lancaster avoided this. John then renewed the siege of Breteuil.
  
  The French force attracted praise for its splendour and the high status of many of its participants, but it made little progress as the town was well-garrisoned and had been left by Lancaster with food for a year. John attempted to mine under the walls, to no avail. Meanwhile, Edward the Black Prince, the son and heir of the English king, assembled an Anglo-Gascon army at Bergerac in south-west France. On 4 August this marched into French-held territory, devastating the countryside as it went. At some point in August an unusually large mobile siege tower was pushed up to the walls of Breteuil and an assault launched. The defenders set fire to the tower and repulsed the attack, inflicting many casualties. Taking Breteuil became a matter of prestige for John and he refused to take the army south to face the Black Prince. (Full article...)

Einstein in 1947

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics. 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 in the German Empire, Einstein moved to Switzerland in 1895, forsaking his German citizenship (as a subject of the Kingdom of Württemberg) the following year. In 1897, 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 German citizen again, this time as a subject of the Kingdom of Prussia. 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.
