Herodotus (c. 484 BC – c. 425 BC) is often
considered the "father of history"
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, and politics. (Full article...)

HMS Agincourt was a dreadnought battleship built in the United Kingdom in the early 1910s. Originally part of Brazil's role in a South American naval arms race, she holds the distinction of mounting more heavy guns (fourteen) and more turrets (seven) than any other dreadnought battleship, in keeping with the Brazilians' requirement for an especially impressive design.
Brazil ordered the ship in 1911 as Rio de Janeiro from the British company Armstrong Whitworth. However, the collapse of Brazil's rubber boom and a warming in relations with Argentina, the country's chief rival, led to the ship's sale while under construction to the Ottoman Empire. The Ottomans renamed her Sultan Osman I, after the empire's founder, and the ship was nearly complete when the First World War broke out. The British government seized her for use by the Royal Navy, together with another Ottoman dreadnought being constructed in Britain. This act caused resentment in the Ottoman Empire, as the payments for both ships were complete. (Full article...) -
Septimius Odaenathus (Palmyrene Aramaic: 𐡠𐡣𐡩𐡮𐡶 (), ʾŌdaynaṯ; Arabic: أذينة, romanized: Uḏayna; c. 220 – 267) was the founder king (malik) of the Palmyrene Kingdom who ruled from Palmyra, Syria. He elevated the status of his kingdom from a regional center subordinate to Rome into a formidable state in South-West Asia. Odaenathus was born into an aristocratic Palmyrene family that had received Roman citizenship in the 190s under the Severan dynasty. He was the son of Hairan, the descendant of Nasor. The circumstances surrounding his rise are ambiguous; he became the lord (ras) of the city, a position created for him, as early as the 240s and by 258, he was styled a consularis, indicating a high status in the Roman Empire.

The Battle of Malvern Hill, also known as the Battle of Poindexter's Farm, was fought on July 1, 1862, between the Confederate Army of Northern Virginia, led by Gen. Robert E. Lee, and the Union Army of the Potomac under Maj. Gen. George B. McClellan. It was the final battle of the Seven Days Battles during the American Civil War, taking place on a 130-foot (40 m) elevation of land known as Malvern Hill, near the Confederate capital of Richmond, Virginia and just one mile (1.6 km) from the James River. Including inactive reserves, more than fifty thousand soldiers from each side took part, using more than two hundred pieces of artillery and three warships.
The Seven Days Battles were the climax of the Peninsula Campaign, during which McClellan's Army of the Potomac sailed around the Confederate lines, landed at the tip of the Virginia Peninsula, southeast of Richmond, and struck inland towards the Confederate capital. Confederate general Joseph E. Johnston fended off McClellan's repeated attempts to take the city, slowing Union progress on the peninsula to a crawl. When Johnston was wounded, Lee took command and launched a series of counterattacks, collectively called the Seven Days Battles. These attacks culminated in the action on Malvern Hill.

Palmyra (/pælˈmaɪrə/ pal-MY-rə; Palmyrene: 𐡶𐡣𐡬𐡥𐡴 (), romanized: Tadmor; Arabic: تَدْمُر, romanized: Tadmur) is an ancient city in central Syria. It is located in the eastern part of the Levant, and archaeological finds date back to the Neolithic period, and documents first mention the city in the early second millennium BCE. Palmyra changed hands on a number of occasions between different empires before becoming a subject of the Roman Empire in the first century CE. (Full article...) -
The Deutschland class was a group of five pre-dreadnought battleships built for the German Kaiserliche Marine (Imperial Navy), the last vessels of that type to be built in Germany. The class comprised Deutschland, the lead ship, Hannover, Pommern, Schlesien, and Schleswig-Holstein. The ships closely resembled those of the preceding Braunschweig class, but with stronger armor and a rearranged secondary battery. Built between 1903 and 1908, they were completed after the launch of the revolutionary British all-big-gun battleship HMS Dreadnought in 1906. As a result, they were obsolescent before entering service. The ships nevertheless saw extensive service in the High Seas Fleet, Germany's primary naval formation, through the late 1900s and early 1910s, when they were used for training, which included overseas cruises.
Following the start of World War I in July 1914, the German fleet adopted a strategy of raids on the British coast, which the five Deutschland-class ships supported. These operations culminated in the Battle of Jutland on 31 May – 1 June 1916, where all five ships saw action, despite their marked inferiority to British dreadnoughts. Regardless, they intervened to protect the battered German battlecruisers from their British counterparts, allowing them to escape. In the confused night actions, Pommern was torpedoed and sunk by a British destroyer. After the battle, the four surviving ships were removed from front-line service and used for coastal defense through mid-1917. Thereafter, Hannover alone remained on patrol duty, while the rest were used as barracks or training ships. After Germany's defeat, the Treaty of Versailles permitted the postwar navy to retain several old battleships for coastal defense, including the four Deutschland-class ships. (Full article...) -
Peter Jeffrey, DSO, DFC (6 July 1913 – 6 April 1997) was a senior officer and fighter ace in the Royal Australian Air Force (RAAF). Born in Tenterfield, New South Wales, he joined the RAAF active reserve in 1934, and transferred to the Permanent Air Force (PAF) shortly before World War II. Posted to the Middle East in July 1940, Jeffrey saw action with No. 3 Squadron and took command of the unit the following year, earning the Distinguished Flying Cross for his energy and fighting skills. He was appointed wing leader of No. 234 Wing RAF in November 1941, and became an ace the same month with his fifth solo victory. The next month he was awarded the Distinguished Service Order for his achievements, which included rescuing a fellow pilot who had crash landed in the desert.
In 1942, Jeffrey was posted to the South West Pacific, where he helped organise No. 75 Squadron for the defence of Port Moresby, and No. 76 Squadron before the Battle of Milne Bay. He served two stints in charge of No. 2 Operational Training Unit in southern Australia before the end of the war, broken by command of No. 1 (Fighter) Wing in the Northern Territory and Western Australia during 1943–44, at which time he was promoted to temporary group captain. Jeffrey was transferred to the RAAF reserve after the war but returned to the PAF in 1951, holding training posts in Victoria and command of RAAF Base Edinburgh in South Australia, before resigning in 1956. Outside the military, he was a grazier and stockbroker. He died in 1997 at the age of 83. (Full article...) -
George Smith Patton Jr. (11 November 1885 – 21 December 1945) was a general in the United States Army who commanded the Seventh Army in the Mediterranean Theater of World War II, then the Third Army in France and Germany after the Allied invasion of Normandy in June 1944.
Born in 1885, Patton attended the Virginia Military Institute and the United States Military Academy at West Point. He studied fencing and designed the M1913 Cavalry Saber, more commonly known as the "Patton Saber." He competed in the modern pentathlon in the 1912 Summer Olympics in Stockholm, Sweden, finishing in fifth place. Patton entered combat during the Pancho Villa Expedition of 1916, the United States' first military action using motor vehicles. He fought in World War I as part of the new United States Tank Corps of the American Expeditionary Forces: he commanded the U.S. tank school in France, then led tanks into combat and was wounded near the end of the war. In the interwar period, Patton became a central figure in the development of the army's armored warfare doctrine, serving in numerous staff positions throughout the country. At the United States' entry into World War II, he commanded the 2nd Armored Division. (Full article...) -

The Battle of Tulagi and Gavutu–Tanambogo was a land battle of the Pacific campaign of World War II, between the forces of the Imperial Japanese Navy and Allied (mainly United States Marine Corps) ground forces. It took place 7–9 August 1942 on the Solomon Islands, during the initial Allied landings in the Guadalcanal campaign.
U.S. Marines of the 1st Marine Division, commanded by U.S. Major General Alexander Vandegrift, and the invasion force under Brigadier General William Rupertus, captured the islands of Tulagi, Gavutu, and Tanambogo. The Japanese Navy had built a naval and seaplane base on these islands. The landings were fiercely resisted by the Japanese Navy troops who, heavily outnumbered and outgunned by the Allied forces, fought and died almost to the last man. (Full article...) -
The Derfflinger class was a class of three battlecruisers (German: Schlachtkreuzer) of the Imperial German Navy. The ships were ordered for the 1912–13 Naval Building Program of the German Imperial Navy as a reply to the Royal Navy's two new Lion-class battlecruisers that had been launched a few years earlier. The preceding Moltke class and the incrementally improved Seydlitz represented the end of the evolution of Germany's first generation of battlecruisers. The Derfflinger class had considerable improvements, including a larger primary armament, all of which was mounted on the centerline. The ships were also larger than the preceding classes. The Derfflinger class used a similar propulsion system, and as a result of the increased displacement were slightly slower.
The class comprised three ships: Derfflinger, Lützow, and Hindenburg. All three of the ships saw active service with the High Seas Fleet during World War I. Derfflinger was commissioned shortly after the outbreak of war, and was present at most of the naval actions in the North Sea, including the battles of Dogger Bank and Jutland. Lützow was commissioned in August 1915, and participated only in the raid on Yarmouth before being sunk at Jutland. Hindenburg was commissioned into the fleet in May 1917, and saw no major action. Derfflinger and Hindenburg were interned at Scapa Flow following the armistice in November 1918. Rear Admiral Ludwig von Reuter, who was in command of the interned High Seas Fleet, ordered the ships to be scuttled in an attempt to prevent their possible seizure by the Royal Navy.

The York City War Memorial is a First World War memorial designed by Sir Edwin Lutyens and located in York in the north of England. Proposals for commemorating York's war dead originated in 1919 but proved controversial. Initial discussions focused on whether a memorial should be a monument or should take on some utilitarian purpose. Several functional proposals were examined until a public meeting in January 1920 opted for a monument. The city engineer produced a cost estimate and the war memorial committee engaged Lutyens, who had recently been commissioned by the North Eastern Railway (NER) to design their own war memorial, also to be sited in York.
Lutyens' first design was approved, but controversy enveloped proposals for both the city's and the NER's memorials. Members of the local community became concerned that the memorials as planned were not in keeping with York's existing architecture, especially as both were in close proximity to the ancient city walls, and that the NER's memorial would overshadow the city's. Continued public opposition forced the committee to abandon the proposed site in favour of one on Leeman Road, just outside the walls, and Lutyens submitted a new design of a War Cross and Stone of Remembrance to fit the location. This was scaled back to the cross alone due to lack of funds. (Full article...) -
Captain Maurice Suckling (4 May 1726 – 14 July 1778) was a Royal Navy officer and politician best known for starting the naval career of his nephew Horatio Nelson and for serving as Comptroller of the Navy from 1775 until his death. Suckling joined the Royal Navy in 1739 and saw service in the English Channel and Mediterranean Sea during the War of the Austrian Succession. With the support of relatives including Prime Minister Sir Robert Walpole, Suckling was promoted quickly and received his first command in 1754. At the start of the Seven Years' War in 1756 he was promoted to captain and given a command on the Jamaica Station. There he played a major part in the Battle of Cap-Français in 1757 and fought an inconclusive skirmish against the French ship Palmier in 1758 before returning to Britain in 1760.
Suckling was employed in the aftermath of the capture of Belle Île in 1761 destroying French fortifications on the Île-d'Aix and went on half pay at the end of the war in 1763. He was given his next command during the Falklands Crisis of 1770, and took his nephew Nelson with him. Despite having misgivings over Nelson's suitability for the navy, Suckling supported him and saw him translated into several more active ships in order to further his naval education when Suckling himself moved to command a guard ship. Suckling left his ship in 1773 and was initially rebuffed in his attempts to gain fresh employment with the navy because of the ongoing peace, but in 1775 First Lord of the Admiralty John Montagu, 4th Earl of Sandwich, appointed him Comptroller of the Navy.

Leslie Hubert Holden, MC, AFC (6 March 1895 – 18 September 1932) was an Australian fighter ace of World War I and later a commercial aviator. A South Australian, he joined the Light Horse in May 1915, serving in Egypt and France. In December 1916, he volunteered for the Australian Flying Corps and qualified as a pilot. As a member of No. 2 Squadron on the Western Front, he gained the sobriquets "Lucky Les" and "the homing pigeon" after a series of incidents that saw him limping back to base in bullet-riddled aircraft. He was awarded the Military Cross, and went on to achieve five aerial victories flying Airco DH.5s and Royal Aircraft Factory S.E.5s.
Promoted to captain, Holden finished the war as an instructor with No. 6 (Training) Squadron in England, where his work earned him the Air Force Cross. After leaving the Australian Flying Corps in 1919, he became a manager at the family firm of Holden's Motor Body Builders and joined the part-time Citizen Air Force, before setting up as a commercial pilot and establishing his own air service. In 1929, he located Charles Kingsford Smith and Charles Ulm in the north-west Australian desert after the pair were reported missing on a flight to England in the Southern Cross. Holden began transport operations in New Guinea in 1931. He was killed the following year in a passenger plane crash in Australia. (Full article...) -
John C. Breckinridge by Mathew Brady
The political career of John C. Breckinridge included service in the state government of Kentucky, the Federal government of the United States, as well as the government of the Confederate States of America. In 1857, 36 years old, he was inaugurated as Vice President of the United States under James Buchanan. He remains the youngest person to ever hold the office. Four years later, he ran as the presidential candidate of a dissident group of Southern Democrats, but lost the election to the Republican candidate Abraham Lincoln.
A member of the Breckinridge political family, John C. Breckinridge became the first Democrat to represent Fayette County in the Kentucky House of Representatives, and in 1851, he was the first Democrat to represent Kentucky's 8th congressional district in over 20 years. A champion of strict constructionism, states' rights, and popular sovereignty, he supported Stephen A. Douglas's Kansas–Nebraska Act as a means of addressing slavery in the territories acquired by the U.S. in the Mexican–American War. Considering his re-election to the House of Representatives unlikely in 1854, he returned to private life and his legal practice. He was nominated for vice president at the 1856 Democratic National Convention, and although he and Buchanan won the election, he enjoyed little influence in Buchanan's administration.

No. 450 Squadron was a unit of the Royal Australian Air Force (RAAF) that operated during World War II. Established at RAAF Station Williamtown, New South Wales, in February 1941, it was the first Australian Article XV squadron formed under the Empire Air Training Scheme.
The squadron embarked for the Middle East in April 1941; its personnel initially consisted solely of ground crew, who joined the pilots of No. 260 Squadron RAF to form No. 260/450 Squadron, which briefly operated Hawker Hurricane fighters in Syria. It was not until February 1942 that No. 450 Squadron, now with its own pilots and equipped with Curtiss P-40 Kittyhawk fighters, commenced operations in earnest. Over the next 15 months, it fought in the North African and Tunisian campaigns in both fighter and fighter-bomber roles, claiming 49 German and Italian aircraft destroyed in the air and earning the nickname "The Desert Harassers".

Shen Kuo (Chinese: 沈括; 1031–1095) or Shen Gua, courtesy name Cunzhong (存中) and pseudonym Mengqi (now usually given as Mengxi) Weng (夢溪翁), was a Chinese polymath, scientist, and statesman of the Song dynasty (960–1279). Shen was a master in many fields of study including mathematics, optics, and horology. In his career as a civil servant, he became a finance minister, governmental state inspector, head official for the Bureau of Astronomy in the Song court, Assistant Minister of Imperial Hospitality, and also served as an academic chancellor. At court his political allegiance was to the Reformist faction known as the New Policies Group, headed by Chancellor Wang Anshi (1021–1085).
In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the pole star and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancers' compasses in regard to declination).
