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...)

The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event and military engagement in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna reclaimed the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States). About one hundred Texians were then garrisoned at the mission, with around a hundred subsequent reinforcements led by eventual Alamo co-commanders James Bowie and William B. Travis. On February 23, approximately 1,500 Mexicans marched into San Antonio de Béxar as the first step in a campaign to retake Texas. In the early morning hours of March 6, the Mexican Army advanced on the Alamo. After repelling two attacks, the Texians were unable to fend off a third attack. As Mexican soldiers scaled the walls, most of the Texian fighters withdrew into interior buildings. Those who were unable to reach these points were slain by the Mexican cavalry as they attempted to escape. Almost all of the Texian inhabitants were killed.
Several noncombatants were sent to Gonzales to spread word of the Texian defeat. The news sparked both a strong rush to join the Texian army and a panic, known as "The Runaway Scrape", in which the Texian army, most settlers, and the government of the new, self-proclaimed but officially unrecognized Republic of Texas fled eastward toward the U.S. ahead of the advancing Mexican Army. Santa Anna's execution of surrendering soldiers during the battle inspired many Texians and Tejanos to join the Texian Army. The Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the conquering of the Mexican state of Coahuila y Tejas by the newly formed Republic of Texas.

The bombing of Yawata (Yahata kūshū) on the night of 15–16 June 1944 marked the beginning of the United States Army Air Forces (USAAF) strategic bombing campaign against the Japanese home islands during the Pacific War and was the first such raid to employ strategic bombers. The raid was undertaken by 75 Boeing B-29 Superfortress heavy bombers staging from bases in China. Only 47 of these aircraft dropped bombs near the raid's primary target, the Imperial Iron and Steel Works at Yawata in northern Kyūshū, and little damage was caused. Five B-29s were lost in accidents during the operation and two were destroyed by Japanese aircraft.
While the raid did not achieve its aims, it raised Japanese civilians' awareness that their country was being defeated and received positive media coverage in the United States. Intelligence gathered by the B-29s also revealed weaknesses in Japan's air defenses and the raid was the second of many on Japan. Yawata was attacked again by B-29s operating from China on 20 August 1944 and much of the city was destroyed in a firebombing raid conducted by B-29s based in the Mariana Islands on 8 August 1945.

Operation Grandslam was an offensive undertaken by United Nations peacekeeping forces from 28 December 1962 to 15 January 1963 against the forces of the State of Katanga, a secessionist state rebelling against the Republic of the Congo (now the Democratic Republic of the Congo) in Central Africa. The Katangese forces were decisively defeated and Katanga was forcibly reintegrated into the Congo.
The United Nations had tried several times to reconcile the government of the Congo with the State of Katanga, which had declared independence under Moïse Tshombe with Belgian support in 1960. Though initially limiting its actions, the United Nations Operation in the Congo became increasingly impatient towards Katanga and Tshombe, drawing up plans to resolve the situation through force. Tshombe continuously violated agreements he had made with the United Nations and the Congolese government by building up his forces and bringing foreign mercenaries into the conflict. The situation reached a breaking point in December 1962 when Katangese gendarmes attacked peacekeeping forces in Katanga. United Nations Secretary-General U Thant authorised a retaliatory offensive to eliminate secessionist opposition. (Full article...) -
The Court of Chancery in the reign of King George I
The Court of Chancery was a court of equity in England and Wales that followed a set of loose rules to avoid a slow pace of change and possible harshness (or "inequity") of the common law. The Chancery had jurisdiction over all matters of equity, including trusts, land law, the estates of lunatics and the guardianship of infants.
Its initial role differed somewhat: as an extension of the lord chancellor's role as Keeper of the King's Conscience, the court was an administrative body primarily concerned with conscientious law. Thus the Court of Chancery had a far greater remit than the common-law courts (whose decisions it had the jurisdiction to overrule for much of its existence) and was far more flexible.

The City of Portsmouth War Memorial, also referred to as the Guildhall Square War Memorial, is a First World War memorial in Guildhall Square in the centre of Portsmouth, Hampshire, on the south coast of England. Portsmouth was and remains a port and home to a major naval dockyard. The dockyard and the armed forces provided much of the employment in the area in the early 20th century. As such, the town suffered significant losses in the First World War. Planning for a war memorial began shortly after the end of the conflict and a committee was established for the purpose. It selected a site adjacent to a railway embankment close to the Town Hall (renamed the Guildhall in 1926 when Portsmouth was granted city status) and chose the architects James Gibson and Walter Gordon, with sculptural elements by Charles Sargeant Jagger, from an open competition.
The memorial consists of a semi-circular sunken recess (exedra) with a screen wall. Bronze panels fixed to the wall list the names of the city's dead. Archways in the wall lead out of Guildhall Square towards Victoria Park and the railway station, and balustrades lead away back into Guildhall Square, terminating in sculptures by Jagger of a life-size soldier and sailor with machine guns. In the centre is a cenotaph surmounted with an urn and decorated on the sides with relief carvings of wartime scenes. The Duke of Connaught unveiled the memorial on 19 October 1921, before its completion. (Full article...) -
Khalid ibn al-Walid ibn al-Mughira al-Makhzumi (Arabic: خالد بن الوليد بن المغيرة المخزومي, romanized: Khālid ibn al-Walīd ibn al-Mughīra al-Makhzūmī; died 642) was a 7th-century Arab military commander. He initially led campaigns against Muhammad on behalf of the Quraysh. He later became a Muslim and spent the remainder of his career serving Muhammad and the first two Rashidun caliphs: Abu Bakr and Umar. Khalid played leading command roles in the Ridda Wars against rebel tribes in Arabia in 632–633, the initial campaigns in Sasanian Iraq in 633–634, and the conquest of Byzantine Syria in 634–638.
As a horseman of the Quraysh's aristocratic Banu Makhzum clan, which ardently opposed Muhammad, Khalid played an instrumental role in defeating Muhammad and his followers during the Battle of Uhud in 625. In 627 or 629, he converted to Islam in the presence of Muhammad, who inducted him as an official military commander among the Muslims and gave him the title of Sayf Allah (lit. 'Sword of God'). During the Battle of Mu'ta, Khalid coordinated the safe withdrawal of Muslim troops against the Byzantines. He also led the Bedouins under the Muslim army during the Muslim conquest of Mecca in 629–630 and the Battle of Hunayn in 630. After Muhammad's death, Khalid was appointed to Najd and al-Yamama to suppress or subjugate the Arab tribes opposed to the nascent Muslim state; this campaign culminated in Khalid's victory over rebel leaders Tulayha and Musaylima at the Battle of Buzakha in 632 and the Battle of Yamama in 633, respectively.

Charles Robert Mowbray Fraser Cruttwell JP (23 May 1887 – 14 March 1941) was a British historian and academic who served as dean and later principal of Hertford College, Oxford. His field of expertise was modern European history, his most notable work being A History of the Great War, 1914–18. He is mainly remembered, however, for the vendetta pursued against him by the novelist Evelyn Waugh, in which Waugh showed his distaste for his former tutor by repeatedly using the name "Cruttwell" in his early novels and stories to depict a sequence of unsavoury or ridiculous characters. The prolonged minor humiliation thus inflicted may have contributed to Cruttwell's eventual mental breakdown.
Cruttwell gained first-class honours at The Queen's College, Oxford, and was elected a Fellow of All Souls College, Oxford, in 1911, and he became a lecturer in history at Hertford College the following year. His academic career was interrupted by service in the First World War during which he suffered severe wounds; he returned to Oxford in 1919 and became dean of Hertford, and then principal of the college in 1930. It was during his tenure as dean that the feud with Evelyn Waugh developed while Waugh was a history scholar at Hertford in 1922–1924. Waugh pursued this hostility until shortly before Cruttwell's death. (Full article...) -
Operation Transom was an attack by Allied forces against the Japanese-occupied city of Surabaya on the Indonesian island of Java during World War II. Conducted by the British-led Eastern Fleet, the operation took place on 17 May 1944 and involved American and British carrier-based aircraft bombing the city's docks and an oil refinery. An American torpedo bomber was shot down, and two British torpedo bombers were lost in accidents.
The attack on Surabaya was the second, and final, joint American-British aircraft carrier raid in the Indian Ocean during 1944. It was undertaken to divert Japanese forces from the Allied landing on Wakde island off New Guinea and make use of the American aircraft carrier on its return voyage to the Pacific. The warships involved in the operation sailed from Ceylon and refuelled in Western Australia before reaching the waters south of Java, where the carriers' aircraft were launched. On the morning of 17 May two groups of Allied aircraft made a coordinated attack on Surabaya's port and several industrial facilities that took the Japanese by surprise. American heavy bombers struck Surabaya that night and Australian aircraft laid mines in nearby waters; these aircraft operated from bases in northern Australia. (Full article...) -
The First Silesian War (German: Erster Schlesischer Krieg) was a war between Prussia and Austria that lasted from 1740 to 1742 and resulted in Prussia's seizing most of the region of Silesia (now in south-western Poland) from Austria. The war was fought mainly in Silesia, Moravia and Bohemia (the lands of the Bohemian Crown) and formed one theatre of the wider War of the Austrian Succession. It was the first of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria in the mid-18th century, all three of which ended in Prussian control of Silesia.
No particular triggering event started the war. Prussia cited its centuries-old dynastic claims on parts of Silesia as a casus belli, but Realpolitik and geostrategic factors also played a role in provoking the conflict. Maria Theresa's contested succession to the Habsburg monarchy provided an opportunity for Prussia to strengthen itself relative to regional rivals such as Saxony and Bavaria. (Full article...) -
The 4th Missouri Infantry Regiment was formed on April 28, 1862, and served in the Confederate States Army during the American Civil War. The infantry regiment did not see action at the Battle of Farmington on May 9, and the Battle of Iuka on September 19 despite being part of the Confederate force present at those battles. As part of Brigadier General Martin E. Green's brigade, the regiment participated in three charges against Union lines on October 3, 1862, during the Second Battle of Corinth. The following day, the regiment, along with the rest of Green's brigade, attacked the new Union lines. Despite initial success, the attack was repulsed by a Union counterattack. The regiment ceased to exist as a separate unit when it was combined with the 1st Missouri Infantry Regiment on November 7, 1862, to form the 1st and 4th Missouri Infantry Regiment (Consolidated).
The combined unit served in the Vicksburg campaign in 1863, before surrendering at the end of the siege of Vicksburg. After undergoing a prisoner exchange, the men rejoined the Confederate Army and served in the Atlanta Campaign and the Battle of Franklin in 1864, still as part of the 1st and 4th Missouri Infantry Regiment (Consolidated). On May 9, 1865, near the end of the war, the consolidated regiment surrendered during the Battle of Fort Blakeley, ending the unit's existence. The 4th Missouri Infantry's battle flag is displayed at the American Civil War Museum. (Full article...) -
SMS Wettin ("His Majesty's Ship Wettin") was a pre-dreadnought battleship of the Wittelsbach class of the German Kaiserliche Marine (Imperial Navy). She was built by Schichau Seebeckwerft in Danzig. Wettin was laid down in October 1899, and was completed October 1902. She and her sister ships—Wittelsbach, Zähringen, Schwaben and Mecklenburg—were the first capital ships built under the Navy Law of 1898. Wettin was armed with a main battery of four 24 cm (9.4 in) guns and had a top speed of 18 knots (33 km/h; 21 mph).
Wettin saw service in I Squadron of the German fleet for most of her career, along with her sister ships. She was occupied with extensive annual training, as well as making good-will visits to foreign countries. The training exercises provided the framework for the High Seas Fleet's operations during World War I. The ship was decommissioned in June 1911 as dreadnought battleships began to enter service but was reactivated for duty as a gunnery training ship between December 1911 and mid-1914.

George Andrew Davis Jr. (December 1, 1920 – February 10, 1952) was a highly decorated fighter pilot and flying ace of the United States Army Air Forces in World War II, and later of the United States Air Force during the Korean War. He was killed in action during a combat mission in northwestern Korea, in an area nicknamed "MiG Alley". For his actions during the Korean War, Davis was posthumously awarded the Medal of Honor and promoted from major to lieutenant colonel.
Born in Dublin, Texas, Davis joined the United States Army Air Corps in early 1942. He was sent to the Pacific Theater after pilot training and flew in the New Guinea and Philippine campaigns, scoring seven victories over Japanese aircraft. He quickly gained a reputation as a skilled pilot and accurate gunner whose "daredevil" flying style contrasted with his reserved personality. (Full article...) -
Gaulois was one of three Charlemagne-class pre-dreadnought battleships built for the French Navy (Marine Nationale) in the mid-1890s. Completed in 1899, she spent most of her career assigned to the Mediterranean Squadron (Escadre de la Méditerranée). The ship accidentally rammed two other French warships early in her career, although neither was seriously damaged, nor was Gaulois.
Following the outbreak of World War I in August 1914, Gaulois escorted troop convoys from French North Africa to France for a month and a half. She was ordered to the Dardanelles in November 1914 to guard against a sortie into the Mediterranean by the ex-German battlecruiser Yavuz Sultan Selim. In 1915, Gaulois joined British ships in bombarding Ottoman fortifications. She was badly damaged during one such bombardment in March and had to beach herself to avoid sinking. She was refloated and sent to Toulon for permanent repairs. Gaulois returned to the Dardanelles and covered the Allied evacuation in January 1916. She was en route to the Dardanelles after a refit in France when she was torpedoed and sunk on 27 December by a German submarine; four crewmen were lost. (Full article...) -
The Battle of Leuthen /ˈlɔɪtən/ was fought on 5 December 1757 between Frederick the Great's Prussian Army and an Austrian army commanded by Prince Charles of Lorraine and Count Leopold Joseph von Daun. Frederick used maneuver warfare and knowledge of the terrain to rout the larger Austrian force completely. The victory ensured Prussian control of Silesia during the Third Silesian War, which was part of the Seven Years' War.
The battle was fought in and around the town of Leuthen (now Lutynia, Poland), 10 km (6 mi) northwest of Breslau, (now Wrocław, Poland), in Prussian (formerly Austrian) Silesia. By exploiting the training of his troops and his superior knowledge of the terrain, Frederick created a diversion at one end of the battlefield and moved most of his smaller army behind a series of low hillocks. The surprise attack in oblique order on the unsuspecting Austrian flank baffled Prince Charles, who took several hours to realize that the main action was to his left, not his right. Within seven hours, the Prussians had destroyed the Austrians and erased any advantage that the Austrians had gained throughout the campaigning in the preceding summer and autumn. Within 48 hours, Frederick had laid siege to Breslau, which resulted in the city's surrender on 19–20 December. (Full article...) -
The 1913 squad, the first that went by the name "Yankees"
The history of the New York Yankees Major League Baseball (MLB) team spans more than a century. Frank J. Farrell and William Stephen Devery bought the rights to an American League (AL) club in New York City after the 1902 season. The team, which became known as the Yankees in 1913, rarely contended for the AL championship before the acquisition of outfielder Babe Ruth after the 1919 season. With Ruth in the lineup, the Yankees won their first AL title in 1921, followed by their first World Series championship in 1923. Ruth and first baseman Lou Gehrig were part of the team's Murderers' Row lineup, which led the Yankees to a then-AL record 110 wins and a Series championship in 1927 under Miller Huggins. They repeated as World Series winners in 1928, and their next title came under manager Joe McCarthy in 1932.
The Yankees won the World Series every year from 1936 to 1939 with a team that featured Gehrig and outfielder Joe DiMaggio, who recorded a record hitting streak during New York's 1941 championship season. New York set a major league record by winning five consecutive championships from 1949 to 1953, and appeared in the World Series nine times from 1955 to 1964. Mickey Mantle, Yogi Berra, and Whitey Ford were among the players fielded by the Yankees during the era. After the 1964 season, a lack of effective replacements for aging players caused the franchise to decline on the field, and the team became a money-loser for owners CBS while playing in an aging stadium.

By mischance, they attacked the wrong target, as the orders were unclear, and as a result suffered great casualties. Alfred, Lord Tennyson's famous poem made the charge a symbol of warfare at both its most courageous and its most tragic. -

Document: John, King of England, his barons and Stephen LangtonCotton MS Augustus II.106, one of four surviving exemplifications of Magna Carta. This document, sealed by King John of England on 15 June 1215 (O.S.), was drafted by the Archbishop of Canterbury to make peace between the unpopular king and a group of rebel barons. The charter promised the protection of church rights, protection for the barons from illegal imprisonment, access to swift justice, and limitations on feudal payments to the Crown.
The document was reissued and renewed several times over the centuries, though its political impact decreased as later laws were passed. The charter was significant because the king had agreed to limit his power, so that although it dealt predominantly with the king and the barons, since the late 16th century it has been considered a symbol of liberty and the freedom of the individual. -

At the time, Denmark, Norway and Sweden were united in the Kalmar Union. The flag is believed to originate from the reign of king Eric of Pomerania due to its inclusion of Pomerania's griffin symbol. For the following five hundred years, the flag was displayed as a war trophy in a Lübeck church until destroyed during a World War II air raid on the city. An 1880s copy of the flag is preserved in the museum at Frederiksborg Palace, Denmark. The saint accompanying the Virgin Mary and infant Christ is Saint James the Greater, identified by his scallop shell emblem. The flag was made of coarse linen. All figures and heraldic insignia were created using oil-based paint. -

Sidney Charles Bartholemew "Ben" Gascoigne AO (11 November 1915 – 25 March 2010) was a New Zealand-born optical astronomer and expert in photometry who played a leading role in the design and commissioning of Australia's largest optical telescope, the Anglo-Australian Telescope, which for a time was one of the world's most important astronomical facilities. Born in Napier, New Zealand, Gascoigne trained in Auckland and at the University of Bristol, before moving to Australia during World War II to work at the Commonwealth Solar Observatory at Mount Stromlo in Canberra. He became skillful in the design and manufacture of optical devices such as telescope elements.
Following the war, Gascoigne and astronomer Gerald Kron used newly modernised telescopes at Mount Stromlo to determine that the distance between our galaxy and the Magellanic Cloud dwarf galaxies had been underestimated by a factor of two. Because this measurement was used to calibrate other distances in astronomy, the result effectively doubled the estimated size of the universe. They also found that star formation in the Magellanic Clouds had occurred more recently than in the Milky Way; this overturned the prevailing view that both had evolved in parallel. A major figure at Mount Stromlo Observatory, Gascoigne helped it develop from a solar observatory to a centre of stellar and galactic research, and was instrumental in the creation of its field observatory in northern New South Wales, Siding Spring Observatory. When the British and Australian governments agreed to jointly build the Anglo-Australian Telescope at Siding Spring, Gascoigne was involved from its initial conception and throughout its lengthy commissioning, taking its first photograph. Gascoigne was made an Officer of the Order of Australia for his contributions to astronomy and to the Anglo-Australian Telescope. (Full article...)
