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 are 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 implications.

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...)

  The 13th Missouri Cavalry Regiment was a cavalry unit that served in the Confederate States Army during the American Civil War. In early April 1863, Captain Robert C. Wood, aide-de-camp to Confederate Major General Sterling Price, was detached to form an artillery unit from some of the men of Price's escort. Wood continued recruiting for the unit, which was armed with four Williams guns, and grew to 275 men by the end of September. The next month, the unit fought in the Battle of Pine Bluff, driving back Union Army troops into a barricaded defensive position, from which the Union soldiers could not be dislodged. By November, the unit, which was known as Wood's Missouri Cavalry Battalion, had grown to 400 men but no longer had the Williams guns. In April 1864, Wood's battalion, which was also known as the 14th Missouri Cavalry Battalion, played a minor role in the defeat of a Union foraging party in the Battle of Poison Spring, before spending the summer of 1864 at Princeton, Arkansas. In September, the unit joined Price's Raid into the state of Missouri, but their assault during the Battle of Pilot Knob failed to capture Fort Davidson.
  
  Wood's battalion fought at the Battle of Little Blue River on October 21 after having participated in some further fighting and operationed against railroads. Two days later, Price's army was defeated at the Battle of Westport, and began retreating through the state of Kansas. During the retreat, on October 25, Wood's battalion was part of the Confederate line when it was shattered at the Battle of Mine Creek. During that action, the unit suffered 72 casualties, 50 of them as prisoners of war and the rest as killed and wounded. It then accompanied Price's army to Laynesport, Arkansas, via the Indian Territory and Texas. At an unknown date, it was enlarged to regimental strength and renamed the 13th Missouri Cavalry Regiment. After Price's Raid, the unit spent the rest of the war serving outpost duty in Arkansas. The Confederate commander of the Trans-Mississippi Department surrendered on June 2, 1865, and the men of the 13th Missouri Cavalry Regiment were paroled six days later. Around 670 men served in the unit over the course of its existence, at least 67 of whom died during that time. (Full article...)

  Rochester Castle - main approach

  
  Rochester Castle stands on the east bank of the River Medway in Rochester, Kent, South East England. The 12th-century keep or stone tower, which is the castle's most prominent feature, is one of the best preserved of its time in England or France.
  
  Situated on the River Medway and Watling Street, Rochester was a strategically important royal castle. During the late medieval period, it helped protect England's south-east coast from invasion. The first castle at Rochester was founded in the aftermath of the Norman Conquest. It was given to Bishop Odo, probably by his half-brother William the Conqueror. During the Rebellion of 1088 over the succession to the English throne, Odo supported Robert Curthose, the Conqueror's eldest son, against William Rufus. It was during this conflict that the castle first saw military action; the city and castle were besieged after Odo made Rochester a headquarters for the rebellion. After the garrison capitulated, this first castle was abandoned. (Full article...)

  Charles Domery (c. 1778 – after 1800), later also known as Charles Domerz, was a Polish soldier serving in the Prussian and French armies, noted for his unusually large appetite. Serving in the Prussian Army against France during the War of the First Coalition, he found that the rations of the Prussians were insufficient and deserted to the French Army in return for food. Although generally healthy, he was voraciously hungry during his time in the French service and ate any available food. While stationed near Paris, he was recorded as having eaten 174 cats in a year, and although he disliked vegetables, he would eat 4 to 5 pounds (1.8 to 2.3 kg) of grass each day if he could not find other food. During service on the French ship Hoche, he attempted to eat the severed leg of a crew member hit by cannon fire, before other members of the crew wrestled it from him.
  
  In February 1799, the Hoche was captured by British forces and the crew, including Domery, were interned in Liverpool, where he shocked his captors with his voracious appetite: despite being put on ten times the usual rations, he ate the prison cat and at least 20 rats, and would often eat the prison candles. In one experiment, over the course of a day, he ate 16 pounds (7.3 kg) of raw cow's udder, raw beef and tallow candles and four bottles of porter, all of which he ate and drank without defecating, urinating, or vomiting.

  Air Vice-Marshal Anderson, c. 1940

  
  Air Vice-Marshal William Hopton Anderson, CBE, DFC (30 December 1891 – 30 December 1975) was a senior commander in the Royal Australian Air Force (RAAF). He flew with the Australian Flying Corps in World War I, earning the Distinguished Flying Cross and the Belgian Croix de guerre for his combat service with No. 3 Squadron on the Western Front in 1917. The following year he took command of No. 7 (Training) Squadron and, later, No.  3 Squadron. Anderson led the Australian Air Corps during its brief existence in 1920–21, before joining the fledgling RAAF. The service's third most-senior officer, he primarily held posts on the Australian Air Board in the inter-war years. He was appointed a Commander of the Order of the British Empire in 1934, and promoted to air commodore in 1938.
  
  At the outbreak of World War II, Anderson was Air Member for Supply. In 1940 he acted as Chief of the Air Staff between the resignation of Air Vice-Marshal Stanley Goble in January and the arrival of Air Chief Marshal Sir Charles Burnett, RAF, the next month. He led the newly formed Central and Eastern Area Commands between December 1940 and July 1943, returning to the Air Board as Air Member for Organisation and Equipment from September 1941 to May 1942. Anderson was founding commandant of the RAAF Staff School from July to November 1943, after which he was appointed Air Member for Personnel. He again served as Staff School commandant from October 1944 until his retirement in April 1946. Known to his colleagues as "Andy" or "Mucker", Anderson died on his birthday in 1975.

  Flight Lieutenant Steege serving with No. 3 Squadron in North Africa, December 1940

  
  Air Commodore Gordon Henry Steege, DSO, DFC (31 October 1917 – 1 September 2013) was a senior officer and pilot in the Royal Australian Air Force (RAAF). He became a fighter ace in World War II, credited with eight aerial victories, and led combat formations at squadron and wing level.
  
  Born in Sydney, Steege joined the RAAF in July 1937. He first saw action in late 1940 with No. 3 (Army Cooperation) Squadron in the Middle East, where he flew Gloster Gladiator, Hawker Hurricane and P-40 Kittyhawk fighters. Achieving victories in all three types, he was awarded the Distinguished Flying Cross after shooting down three German aircraft during a single sortie in February 1941. He rose to command No. 450 Squadron in the Desert Air Force, before returning to Australia in December 1942. Posted to the South West Pacific, he commanded No. 14 Mobile Fighter Sector and, later, Nos. 73 and 81 (Fighter) Wings. He earned the Distinguished Service Order in April 1944 for his "outstanding leadership", and finished the war a group captain. (Full article...)

  Matthäus Merian the Elder, "Battle of Trebbia" (1625)

  
  The Battle of the Trebia (or Trebbia) was the first major battle of the Second Punic War, fought between the Carthaginian forces of Hannibal and a Roman army under Sempronius Longus on 22 or 23 December 218 BC. Each army had a strength of about 40,000 men; the Carthaginians were stronger in cavalry, the Romans in infantry. The battle took place on the flood plain of the west bank of the lower Trebia River, not far from the settlement of Placentia (modern Piacenza), and resulted in a heavy defeat for the Romans.
  
  War broke out between Carthage and Rome in 218 BC. The leading Carthaginian general, Hannibal, responded by leading a large army out of Iberia (modern Spain and Portugal), through Gaul, across the Alps and into Cisalpine Gaul (in northern Italy). The Romans went on the attack against the reduced force which had survived the rigours of the march, and Publius Scipio personally led the cavalry and light infantry of the army he commanded against the Carthaginian cavalry at the Battle of Ticinus. The Romans were soundly beaten and Scipio was wounded. The Romans retreated to near Placentia, fortified their camp and awaited reinforcement. The Roman army in Sicily under Sempronius was redeployed to the north and joined with Scipio's force. After a day of heavy skirmishing in which the Romans gained the upper hand, Sempronius was eager for a battle. (Full article...)

  Joseph Benson Foraker (July 5, 1846 – May 10, 1917) was an American politician of the Republican Party who served as the 37th governor of Ohio from 1886 to 1890 and as a United States senator from Ohio from 1897 until 1909.
  
  Foraker was born in rural Ohio; he enlisted at age 16 in the Union Army during the American Civil War. He fought for almost three years, attaining the rank of captain. After the war, he was a member of Cornell University's first graduating class, and became a lawyer. He was elected a judge in 1879 and became known as a political speaker. He was defeated in his first run for the governorship in 1883, but was elected two years later. As Ohio governor, he built an alliance with the Republican Party "boss" Mark Hanna, but fell out with him in 1888. Foraker was defeated for reelection in 1889, but was elected U.S. senator by the Ohio General Assembly in 1896, after an unsuccessful bid for that office in 1892. (Full article...)

  Bockscar, a Silverplate B-29 Superfortress of the 509th Composite Group, dropped an atomic bomb on Nagasaki

  
  
  Silverplate was the code reference for the United States Army Air Forces' participation in the Manhattan Project during World War II. Originally the name for the aircraft modification project which enabled a B-29 Superfortress bomber to drop an atomic weapon, "Silverplate" eventually came to identify the training and operational aspects of the program as well. The original directive for the project had as its subject line "Silver Plated Project," but continued usage of the term shortened it to "Silverplate".
  
  Testing began with scale models at the Naval Proving Ground in Dahlgren, Virginia, in August 1943. Modifications began on a prototype Silverplate B-29 known as the "Pullman" in November 1943, and it was used for bomb flight testing at Muroc Army Air Field in California commencing in March 1944. The testing resulted in further modifications to both the bombs and the aircraft. (Full article...)

  The frontispiece of the 1920 edition of Tod's Annals and Antiquities of Rajast'han

  
  Lieutenant-Colonel James Tod (20 March 1782 – 18 November 1835) was an officer of the British East India Company and an Oriental scholar. He combined his official role and his amateur interests to create a series of works about the history and geography of India, and in particular the area then known as Rajputana that corresponds to the present day state of Rajasthan, and which Tod referred to as Rajast'han.
  
  Tod was born in London and educated in Scotland. He joined the East India Company as a military officer and travelled to India in 1799 as a cadet in the Bengal Army. He rose quickly in rank, eventually becoming captain of an escort for an envoy in a Sindian royal court. After the Third Anglo-Maratha War, during which Tod was involved in the intelligence department, he was appointed Political Agent for some areas of Rajputana. His task was to help unify the region under the control of the East India Company. During this period Tod conducted most of the research that he would later publish. Tod was initially successful in his official role, but his methods were questioned by other members of the East India Company. Over time, his work was restricted and his areas of oversight were significantly curtailed. In 1823, owing to declining health and reputation, Tod resigned his post as Political Agent and returned to England. (Full article...)

  One of T2's sister ships, T3

  
  T2 was a seagoing torpedo boat operated by the Royal Yugoslav Navy between 1923 and 1939. Originally 77 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1914, she was armed with two 66 mm (2.6 in) guns and four 450 mm (17.7 in) torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, patrol, escort, minesweeping and minelaying tasks, anti-submarine operations, and shore bombardment missions. In 1917, the suffixes of all Austro-Hungarian torpedo boats were removed, and thereafter she was referred to as 77. The vessel was in the Bocche di Cattaro during the short-lived mutiny by Austro-Hungarian sailors in early February 1918; members of her crew raised the red flag but undertook no other mutinous actions. 77 was part of the escort force for the Austro-Hungarian dreadnought Szent István during the action that resulted in the sinking of that ship by Italian torpedo boats in June 1918.
  
  Following Austria-Hungary's defeat in 1918, 77 was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which later became the Royal Yugoslav Navy, and was renamed T2 and had her armament upgraded. At the time, she and seven other 250t-class boats were the only modern sea-going vessels of the fledgling maritime force. During the interwar period, the navy was involved in training exercises and cruises to friendly ports, but activity was limited by reduced naval budgets. Worn out after twenty-five years of service, T2 was stricken from the naval register and scrapped in 1939. (Full article...)

  A bomb exploding near the Berghof, Adolf Hitler's residence at Obersalzberg, on 25 April 1945

  
  The bombing of Obersalzberg was an air raid carried out by the Royal Air Force's Bomber Command on 25 April 1945 during the last days of World War II in Europe. The operation targeted Obersalzberg, a complex of residences and bunkers in Bavaria which had been built for Adolf Hitler and other key members of Germany's leadership. Many buildings in the complex were destroyed, though Hitler's residence and the bunker network were only slightly damaged. Two Allied bombers were shot down with the loss of four airmen, and 31 Germans were killed.
  
  Historians have identified several motives for the attack on Obersalzberg. These include supporting Allied ground forces, demonstrating the effectiveness of the British heavy bomber force, convincing die-hard Germans that the war was lost and obscuring the memory of pre-war appeasement policies. The attack was conducted by a large force of 359 heavy bombers in an attempt to destroy the bunkers located below Obersalzberg, from which the Allies feared that senior members of the German Government would command an Alpine Fortress. After difficulties locating and marking the targets were overcome, the bombers attacked in two waves. The approximately 3,000 people at Obersalzberg sheltered in bunkers, and the nearby town of Berchtesgaden was undamaged. Hitler was in Berlin at the time of the attack and Hermann Göring, the only senior Nazi at Obersalzberg, survived. (Full article...)

  An Arab–Byzantine battle as depicted in the 12th-century Madrid Skylitzes

  
  The Battle of Lalakaon (Greek: Μάχη τοῦ Λαλακάοντος), or Battle of Poson or Porson (Μάχη τοῦ Πό(ρ)σωνος), was fought in 863 between the Byzantine Empire and an invading Arab army in Paphlagonia (modern northern Turkey). The Byzantine army was led by Petronas, the uncle of Emperor Michael III, although Arab sources also mention the presence of the Emperor in person. The Arabs were led by the emir of Melitene (Malatya), Umar al-Aqta.
  
  Umar al-Aqta overcame initial Byzantine resistance to his invasion and reached the Black Sea. The Byzantines then mobilized their forces and encircled the Arab army near the Lalakaon river. The subsequent battle ended in a Byzantine victory and the emir's death on the field, and was followed by a successful Byzantine counteroffensive across the border. These victories were decisive; the main threats to the Byzantine borderlands were eliminated, and the era of Byzantine ascendancy in the East (culminating in the 10th-century conquests) began.

  Woodcut vignette of Alboin in the 1493 Nuremberg Chronicle

  
  Alboin (530s – 28 June 572) was king of the Lombards from about 560 until 572. During his reign the Lombards ended their migrations by settling in Italy, the northern part of which Alboin conquered between 569 and 572. He had a lasting effect on Italy and the Pannonian Basin; in the former, his invasion marked the beginning of centuries of Lombard rule, and in the latter, his defeat of the Gepids and his departure from Pannonia ended the dominance there of the Germanic peoples.
  
  The period of Alboin's reign as king in Pannonia following the death of his father, Audoin, was one of confrontation and conflict between the Lombards and their main neighbours, the Gepids. The Gepids initially gained the upper hand, but in 567, thanks to his alliance with the Avars, Alboin inflicted a decisive defeat on his enemies, whose lands the Avars subsequently occupied. The increasing power of his new neighbours caused Alboin some unease however, and he therefore decided to leave Pannonia for Italy, hoping to take advantage of the Byzantine Empire's vulnerability in defending its territory in the wake of the Gothic War.

  Operation PBHistory was a covert operation carried out in Guatemala by the United States Central Intelligence Agency (CIA). It followed Operation PBSuccess, which led to the overthrow of Guatemalan President Jacobo Árbenz in June 1954 and ended the Guatemalan Revolution. PBHistory attempted to use documents left behind by Árbenz's government and by organizations related to the communist Guatemalan Party of Labor to demonstrate that the Guatemalan government had been under the influence of the Soviet Union, and to use those documents to obtain further intelligence that would be useful to US intelligence agencies. It was an effort to justify the overthrow of the elected Guatemalan government in response to the negative international reactions to PBSuccess. The CIA also hoped to improve its intelligence resources about communist parties in Latin America, a subject on which it had little information.
  
  The first phase of the operation began soon after Árbenz's resignation on June 27, 1954: several agents were dispatched to Guatemala beginning on July 4. These included agents of the CIA and the Office of Intelligence Research (OIR). The first phase involved the collection of 150,000 documents from sources including Árbenz's personal possessions, trade union offices, and police agencies. The ruling military junta led by Carlos Castillo Armas aided these efforts. Following a presentation made to US President Dwight Eisenhower on July 20, a decision was taken to accelerate the operation, and the number of people working in Guatemala was increased. The new team members posed as unaffiliated with the US government to maintain plausible deniability. The operation helped set up the Guatemalan National Committee of Defense Against Communism, which was covertly funded by the CIA: agents of the committee became involved in PBHistory. The team studied over 500,000 documents in total, and finished processing documents on September 28, 1954. (Full article...)

  A merchant ship unloads supplies into a DUKW.

  
  American transportation played a crucial part in the military logistics of the World War II Siegfried Line campaign, which ran from the end of the expulsion of the German armies from Normandy in mid-September 1944 until December 1944, when the American Army was engulfed by the German Ardennes offensive. In August 1944, the Supreme Allied Commander, General Dwight D. Eisenhower, elected to continue the pursuit of the retreating German forces beyond the Seine instead of pausing to build up supplies and establish the lines of communication as called for in the original Operation Overlord plan. The subsequent advance to the German border stretched the American logistical system to its breaking point, and the advance came to a halt in mid-September.
  
  The Germans attempted to delay the Allied advance until the onset of bad weather by denying access to ports and demolishing communications infrastructure in order to give their own forces time to recover. Between September and November, the American forces in Europe suffered from severe transportation problems. In September, Cherbourg was the only deep-water port in northwest Europe in Allied hands capable of handling Liberty ships, but it had been badly damaged, and took a long time to restore. Smaller ports could handle only small, shallow-draft coastal trading vessels known as "coasters". Two-thirds of the British coaster fleet, on which critical industries depended, was dedicated to the campaign. Over time, rough seas, enemy action and continuous use laid up a quarter of the coaster fleet for repairs. From September onwards, an increasing volume of supplies came directly from the United States. These were stowed in Liberty ships so as to make optimal use of their cargo space. The shipments frequently included heavy and bulky items that required dockside cranes to unload. The available port capacity was insufficient to unload the ships arriving. As the number of ships awaiting discharge in European waters climbed, turnaround times increased, and fewer ships reported back to port in the United States, precipitating a widespread shipping crisis.

  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.

  Apollo 11

  Apollo 11 was the fifth crewed mission of NASA's Apollo program. After launching from the Kennedy Space Center in Florida on July 16, 1969, commander Neil Armstrong and Apollo Lunar Module pilot Buzz Aldrin landed Eagle in Mare Tranquillitatis on July 20, at 20:17:40 UTC, while command module pilot Michael Collins remained on Columbia in lunar orbit. Armstrong was the first to exit the spacecraft, stepping onto the surface 6 hours and 39 minutes later, on July 21, at 02:56:15 UTC; nineteen minutes later, Aldrin joined him on extravehicular activity, which lasted 2 hours, 31 minutes and 40 seconds. Armstrong and Aldrin lifted off from Tranquility Base after almost 22 hours on the lunar surface and rejoined Collins in the command module, before splashing down in the Pacific Ocean on July 24.
  
  The mission was planned to the minute, with the majority of the photographic tasks performed by Armstrong with a single Hasselblad camera. Most of the photographs taken on the Moon that include an astronaut are of Aldrin; there are only five images of Armstrong partly shown or reflected, as in this photograph, with Armstrong and the lunar module reflected in Aldrin's helmet visor. "As the sequence of lunar operations evolved," Aldrin explained, "Neil had the camera most of the time [...] It wasn't until we were back on Earth and in the Lunar Receiving Laboratory looking over the pictures that we realized there were few pictures of Neil."

Posthumous portrait

Du Fu (Chinese: 杜甫; pinyin: Dù Fǔ; Wade–Giles: Tu Fu; 712–770) was a Chinese poet and politician during the Tang dynasty. Together with his elder contemporary and friend Li Bai, Du is often considered one of the greatest Chinese poets. His greatest ambition was to serve his country as a successful civil servant, but Du proved unable to make the necessary accommodations. His life, like all of China, was devastated by the An Lushan rebellion of 755, and his last 15 years were a time of almost constant unrest.

Although initially he was little-known to other writers, his works came to be hugely influential in both Chinese and Japanese literary culture. Of his poetic writing, nearly fifteen hundred poems have been preserved over the ages. He has been called the "Poet-Historian" and the "Poet-Sage" by Chinese critics, while the range of his work has allowed him to be introduced to Western readers as "the Chinese Virgil, Horace, Ovid, Shakespeare, Milton, Burns, Wordsworth, Béranger, Hugo or Baudelaire".
