Historia by Nikolaos Gyzis

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...)

  Australian soldiers from the 2/16th Infantry Battalion arriving at Kaiapit after the area was captured by the 2/6th Independent Company

  Australian soldiers from the 2/16th Battalion arriving at Kaiapit on 20 September after the area was captured by the 2/6th Independent Company

  
  The Battle of Kaiapit was an action fought in 1943 between Australian and Japanese forces in New Guinea during the Markham and Ramu Valley – Finisterre Range campaign of World War II. Following the landings at Nadzab and at Lae, the Allies attempted to exploit their success with an advance into the upper Markham Valley, starting with Kaiapit. The Japanese intended to use Kaiapit to threaten the Allied position at Nadzab, and to create a diversion to allow the Japanese garrison at Lae time to escape.
  
  The Australian 2/6th Independent Company flew in to the Markham Valley from Port Moresby in 13 USAAF C-47 Dakotas, making a difficult landing on a rough airstrip. Unaware that a much larger Japanese force was also headed for Kaiapit, the company attacked the village on 19 September to secure the area so that it could be developed into an airfield. The company then held it against a strong counter-attack. During two days of fighting the Australians defeated a larger Japanese force while suffering relatively few losses. (Full article...)

  Ælle's name is visible in this line from the Parker manuscript of the Anglo-Saxon Chronicle, written c. 890

  
  Ælle (also Aelle or Ella) is recorded in much later medieval sources as the first king of the South Saxons, reigning in what is now called Sussex, England, from 477 to perhaps as late as 514.
  
  According to the Anglo-Saxon Chronicle, Ælle and three of his sons are said to have landed at a place called Cymensora and fought against the local Britons. The chronicle goes on to report a victory in 491, at present day Pevensey, where the battle ended with the Saxons slaughtering their opponents to the last man. (Full article...)

  Blair Wark c. 1919

  
  Blair Anderson Wark, VC, DSO (27 July 1894 – 13 June 1941) was an Australian soldier, quantity surveyor, and a recipient of the Victoria Cross, the highest decoration for gallantry "in the face of the enemy" that can be awarded to members of the British and other Commonwealth armed forces. A member of the Citizen Military Forces from 1912, Wark enlisted in the Australian Imperial Force on 5 August 1915 for service in the First World War. After initially being employed in the defence of the Suez Canal, his battalion was shipped to the Western Front; it was here that Wark was twice decorated for his bravery and leadership. Having received the Distinguished Service Order in 1917 for his actions at the Battle of Polygon Wood, Wark was awarded the Victoria Cross in 1918 for his leadership and gallantry when in temporary command of his battalion over a three-day period, while conducting operations against the Hindenburg Line.
  
  Returning to Australia after the war, Wark resumed work as a quantity surveyor and established his own business. He became a respected member of Australian society, holding positions and directorships in several companies and charities until 1940, when he re-enlisted in the Citizen Military Forces for service in the Second World War. Wark was promoted to lieutenant colonel and assumed command of the 1st Battalion (City of Sydney's Own Regiment), but died suddenly at Puckapunyal Camp, Victoria, of coronary heart disease, aged 46.

  Choe Bu (Korean: 최부, 1454–1504) was a Korean diarist, historian, politician, and travel writer during the early Joseon Dynasty. He was most well known for the account of his shipwrecked travels in China from February to July 1488, during the Ming dynasty (1368–1644). He was eventually banished from the Joseon court in 1498 and executed in 1504 during two political purges. However, in 1506 he was exonerated and given posthumous honors by the Joseon court.
  
  Choe's diary accounts of his travels in China became widely printed during the 16th century in both Korea and Japan. Modern historians also refer to his written works, since his travel diary provides a unique outsider's perspective on Chinese culture in the 15th century. The attitudes and opinions expressed in his writing represent in part the standpoints and views of the 15th century Confucian Korean literati, who viewed Chinese culture as compatible with and similar to their own. His description of cities, people, customs, cuisines, and maritime commerce along China's Grand Canal provides insight into the daily life of China and how it differed between northern and southern China during the 15th century.

  SMS Pommern in 1907

  
  SMS Pommern was one of five Deutschland-class pre-dreadnought battleships built for the Kaiserliche Marine between 1904 and 1906. Named after the Prussian province of Pomerania, she was built at the AG Vulcan yard at Stettin, Germany (now Szczecin, Poland), where she was laid down on 22 March 1904 and launched on 2 December 1905. She was commissioned into the navy on 6 August 1907. The ship was armed with a battery of four 28 cm (11 in) guns and had a top speed of 18 knots (33 km/h; 21 mph). The ships of her class were already outdated by the time they entered the service, being inferior in size, armor, firepower, and speed to the revolutionary new battleship HMS Dreadnought.
  
  After commissioning, Pommern was assigned to II Battle Squadron of the High Seas Fleet, where she served throughout her peacetime career and the first two years of World War I. Before the war, the fleet was primarily occupied with cruises and extensive training exercises, developing strategic concepts for use in a future conflict. At the start of the war, Pommern and the rest of II Battle Squadron were tasked with supporting the defenses of the German Bight, and were stationed at the mouth of the Elbe. They also participated in several fruitless sorties into the North Sea in attempts to lure out and destroy a portion of the British Grand Fleet. (Full article...)

  U.S. Marines cross the Matanikau River on a raft ferry in November 1942

  
  The Matanikau Offensive, from 1–4 November 1942, sometimes referred to as the Fourth Battle of the Matanikau, was an engagement between United States (U.S.) Marine and Army and Imperial Japanese Army forces around the Matanikau River and Point Cruz area on Guadalcanal during the Guadalcanal campaign of World War II. The action was one of the last of a series of engagements between U.S. and Japanese forces near the Matanikau River during the campaign.
  
  In the engagement, seven battalions of U.S. Marine and Army troops under the overall command of Alexander Vandegrift and tactical command of Merritt A. Edson, following up on the U.S. victory in the Battle for Henderson Field, crossed the Matanikau River and attacked Japanese Army units between the river and Point Cruz, on the northern Guadalcanal coast. The area was defended by the Japanese Army's 4th Infantry Regiment under Nomasu Nakaguma along with various other support troops, under the overall command of Harukichi Hyakutake. After inflicting heavy casualties on the Japanese defenders, U.S. forces halted the offensive and temporarily withdrew because of a perceived threat from Japanese forces elsewhere in the Guadalcanal area.

  In 1992, Ross Perot ran unsuccessfully as an independent candidate for President of the United States. Perot was a Texas industrialist who had never served as a public official, but he had experience as the head of several successful corporations and had been involved in public affairs for the previous three decades. Grass-root organizations sprang up in every state to help Perot achieve ballot access following his announcement on the February 20, 1992, edition of Larry King Live. James Stockdale, a retired Navy vice admiral, was Perot's running mate.
  
  Perot focused the campaign on his plans to balance the federal budget, further economic nationalism, strengthen the war on drugs, and implement "electronic town halls" throughout the nation for "direct democracy". His views were described as a combination of "East Texas populism with high-tech wizardry". Supporters saw him as a non-political and witty "folk hero", but critics described him as "authoritarian" and "short-tempered". (Full article...)

  L 20e α was a design for a class of battleships to be built in 1918 for the German Kaiserliche Marine (Imperial Navy) during World War I. Design work on the class of battleship to succeed the Bayern-class battleships began in 1914, but the outbreak of World War I in July 1914 led to these plans being shelved. Work resumed in early 1916 and lessons from the Battle of Jutland, fought later that year, were incorporated into the design. Reinhard Scheer, the commander of the fleet, wanted larger main guns and a higher top speed than earlier vessels, to combat the latest ships in the British Royal Navy. A variety of proposals were submitted, with armament ranging from the same eight 38 cm (15 in) guns of the Bayern class to eight 42 cm (16.5 in) guns.
  
  Work on the design was completed by September 1918, but by then there was no chance for them to be built. Germany's declining war situation and the reallocation of resources to support the U-boat campaign meant the ships would never be built. The ships would have been significantly larger than the preceding Bayern-class battleships, at 238 m (780 ft 10 in) long, compared to 180 m (590 ft 7 in) for the preceding ships. The L 20e α class would have been significantly faster, with a top speed of 26 knots (48 km/h; 30 mph), compared to the 21-knot (39 km/h; 24 mph) maximum of the Bayerns and would have been the first German warships to have mounted guns larger than 38 cm.

  Akagi conducting flight operations, April 1942

  Akagi (Japanese: 赤城, "Red castle", named after Mount Akagi) was an aircraft carrier built for the Imperial Japanese Navy (IJN). Though she was laid down as an Amagi-class battlecruiser, Akagi was converted to an aircraft carrier while still under construction to comply with the terms of the Washington Naval Treaty. The ship was rebuilt from 1935 to 1938 with her original three flight decks consolidated into a single enlarged flight deck and an island superstructure. The second Japanese aircraft carrier to enter service, and the first large or "fleet" carrier, Akagi and the related Kaga figured prominently in the development of the IJN's new carrier striking force doctrine that grouped carriers together, concentrating their air power. This doctrine enabled Japan to attain its strategic goals during the early stages of the Pacific War from December 1941 until mid-1942.
  
  Akagi's aircraft served in the Second Sino-Japanese War in the late 1930s. Upon the formation of the First Air Fleet or Kido Butai (Striking Force) in early 1941, she became its flagship, and remained so for the duration of her service. With other fleet carriers, she took part in the Attack on Pearl Harbor in December 1941 and the invasion of Rabaul in the Southwest Pacific in January 1942. The following month, her aircraft bombed Darwin, Australia, and assisted in the conquest of the Dutch East Indies. In March and April 1942, Akagi's aircraft helped sink a British heavy cruiser and an Australian destroyer in the Indian Ocean Raid. (Full article...)

  Holmes, c. 1879

  
  Oliver Wendell Holmes Sr. (/hoʊmz/; August 29, 1809 – October 7, 1894) was an American physician, poet, and polymath based in Boston. Grouped among the fireside poets, he was acclaimed by his peers as one of the best writers of the day. His most famous prose works are the "Breakfast-Table" series, which began with The Autocrat of the Breakfast-Table (1858). He was also an important medical reformer. In addition to his work as an author and poet, Holmes also served as a physician, professor, lecturer, and inventor.
  
  Born in Cambridge, Massachusetts, Holmes was educated at Phillips Academy and Harvard College. After graduating from Harvard in 1829, he briefly studied law before turning to the medical profession. He began writing poetry at an early age; one of his most famous works, "Old Ironsides", was published in 1830 and was influential in the eventual preservation of the USS Constitution. Following training at the prestigious medical schools of Paris, Holmes was granted his Doctor of Medicine degree from Harvard Medical School in 1836. He taught at Dartmouth Medical School before returning to teach at Harvard and, for a time, served as dean there. During his long professorship, he became an advocate for various medical reforms and notably posited the controversial idea that doctors were capable of carrying puerperal fever from patient to patient. Holmes retired from Harvard in 1882 and continued writing poetry, novels and essays until his death in 1894. (Full article...)

  Electrum coin with Theodore (left) blessed by Thessalonica's patron, St. Demetrius

  
  Theodore Komnenos Doukas (Greek: Θεόδωρος Κομνηνὸς Δούκας, Theodōros Komnēnos Doukas; Latinized as Theodore Comnenus Ducas; died c. 1253) or Theodore Angelos Komnenos was the ruler of Epirus and Thessaly from 1215 to 1230 and of Thessalonica and most of Macedonia and western Thrace from 1224 to 1230. He was also the power behind the rule of his sons John and Demetrios over Thessalonica in 1237–1246.
  
  Theodore was the scion of a distinguished Byzantine aristocratic family related to the imperial Komnenos, Doukas, and Angelos dynasties. Nevertheless, nothing is known about Theodore's life before the conquest of Constantinople and dissolution of the Byzantine Empire by the Fourth Crusade in 1204. Following the fall of Constantinople, he served Theodore I Laskaris, founder of the Empire of Nicaea, for a few years before being called to Epirus, where his half-brother Michael I Komnenos Doukas had founded an independent principality. When Michael died in 1215, Theodore sidelined his brother's underage and illegitimate son Michael II and assumed the governance of the Epirote state. Theodore continued his brother's policy of territorial expansion. Allied with Serbia, he expanded into Macedonia, threatening the Latin Kingdom of Thessalonica. The capture of the Latin Emperor Peter II of Courtenay in 1217 opened the way to the gradual envelopment of Thessalonica, culminating in the city's fall in 1224. (Full article...)

  Thaddeus Stevens (April 4, 1792 – August 11, 1868) was an American politician and lawyer who served as a member of the United States House of Representatives from Pennsylvania, being one of the leaders of the Radical Republican faction of the Republican Party during the 1860s. A fierce opponent of slavery and discrimination against black Americans, Stevens sought to secure their rights during Reconstruction, leading the opposition to U.S. President Andrew Johnson. As chairman of the House Ways and Means Committee during the American Civil War, he played a leading role, focusing his attention on defeating the Confederacy, financing the war with new taxes and borrowing, crushing the power of slave owners, ending slavery, and securing equal rights for the freedmen.
  
  Stevens was born in rural Vermont, in poverty, and with a club foot, which left him with a permanent limp. He moved to Pennsylvania as a young man and quickly became a successful lawyer in Gettysburg. He interested himself in municipal affairs and then in politics. He was an active leader of the Anti-Masonic Party, as a fervent believer that Freemasonry in the United States was an evil conspiracy to secretly control the republican system of government. He was elected to the Pennsylvania House of Representatives, where he became a strong advocate of free public education. Financial setbacks in 1842 caused him to move his home and practice to the larger city of Lancaster. There, he joined the Whig Party and was elected to Congress in 1848. His activities as a lawyer and politician in opposition to slavery cost him votes, and he did not seek reelection in 1852. After a brief flirtation with the Know-Nothing Party, Stevens joined the newly formed Republican Party and was elected to Congress again in 1858. There, with fellow radicals such as Massachusetts Senator Charles Sumner, he opposed the expansion of slavery and concessions to the South as the war came. (Full article...)

  Lion underway

  
  HMS Lion was a battlecruiser built for the Royal Navy in the 1910s. She was the lead ship of her class, which were nicknamed the "Splendid Cats". They were significant improvements over their predecessors of the Indefatigable class in terms of speed, armament and armour. This was in response to the first German battlecruisers, the Moltke class, which were very much larger and more powerful than the first British battlecruisers, the Invincible class.
  
  Lion served as the flagship of the Grand Fleet's battlecruisers throughout World War I, except when she was being refitted or under repair. She sank the German light cruiser Cöln during the Battle of Heligoland Bight and served as Vice-Admiral David Beatty's flagship at the Battles of Dogger Bank and Jutland. She was so badly damaged at the first of these battles that she had to be towed back to port and was under repair for more than two months. During the Battle of Jutland she suffered a serious propellant fire that could have destroyed the ship had it not been for the bravery of Royal Marine Major Francis Harvey, the gun turret commander, who posthumously received the Victoria Cross for having ordered the magazine flooded. The fire destroyed one gun turret which had to be removed for rebuilding while she was under repair for several months. She spent the rest of the war on uneventful patrols in the North Sea, although she did provide distant cover during the Second Battle of Heligoland Bight in 1917. She was put into reserve in 1920 and sold for scrap in 1924 under the terms of the Washington Naval Treaty. (Full article...)

  The Royal Artillery Memorial is a First World War memorial located on Hyde Park Corner in London, England. Designed by Charles Sargeant Jagger, with architectural work by Lionel Pearson, and unveiled in 1925, the memorial commemorates the 49,076 soldiers from the Royal Artillery killed in the First World War. The static nature of the conflict, particularly on the Western Front, meant that artillery played a major role in the war, though physical reminders of the fighting were often avoided in the years after the war. The Royal Artillery War Commemoration Fund (RAWCF) was formed in 1918 to preside over the regiment's commemorations, aware of some dissatisfaction with memorials to previous wars. The RAWCF approached several eminent architects but its insistence on a visual representation of artillery meant that none was able to produce a satisfactory design. Thus they approached Jagger, himself an ex-soldier who had been wounded in the war. Jagger produced a design which was accepted in 1922, though he modified it several times before construction.
  
  The memorial consists of a Portland stone cruciform base supporting a one-third over-lifesize sculpture of a howitzer (a type of artillery field gun), which Jagger based on a gun in the Imperial War Museum. At the end of each arm of the cross is a sculpture of a soldier—an officer at the front (south side), a shell carrier on the east side, a driver on the west side, and at the rear (north) a dead soldier. The sides of the base are decorated with relief sculptures depicting wartime scenes. The realism of the memorial, with the depiction of the howitzer and the dead soldier, differed significantly from other First World War memorials, notably the influential Cenotaph, which used pure architectural forms and classical symbolism. The design was controversial when unveiled; some critics viewed the dead soldier as too graphic or felt that the howitzer did not lend itself to rendition in stone. Nonetheless, the memorial was popular with others, including ex-servicemen, and later came to be recognised as Jagger's masterpiece and one of Britain's finest war memorials. (Full article...)

  Shekel minted by the Libyans during the war, depicting Herakles and a lion, with the legend ΛIBYΩN ("the Libyans"). Above the lion, the Phoenician letter M could stand for Mathos, a leader of the rebellion.

  
  The Mercenary War, also known as the Truceless War, was a mutiny by troops that were employed by Carthage at the end of the First Punic War (264–241 BC), supported by uprisings of African settlements revolting against Carthaginian control. It lasted from 241 to late 238 or early 237 BC and ended with Carthage suppressing both the mutiny and the revolt.
  
  The war began in 241 BC as a dispute over the payment of wages owed to 20,000 foreign soldiers who had fought for Carthage in Sicily during the First Punic War. When a compromise seemed to have been reached, the army erupted into full-scale mutiny under the leadership of Spendius and Matho. 70,000 Africans from Carthage's oppressed dependent territories flocked to join them, bringing supplies and finance. War-weary Carthage fared poorly in the initial engagements of the war, especially under the generalship of Hanno. Hamilcar Barca, a veteran of the campaigns in Sicily (and father of Hannibal Barca), was given joint command of the army in 240 BC; and supreme command in 239 BC. He campaigned successfully, initially demonstrating leniency in an attempt to woo the rebels over. To prevent this, in 240 BC Spendius and Autaritus tortured 700 Carthaginian prisoners to death (including Gisco), after which the war was pursued with great brutality on both sides.

  Knight

  Illustration: Anton Sorg; Restoration: Lise Broer

  A knight, a member of the warrior class of the Middle Ages in Europe, in Gothic plate armour, from a German book illustration published 1483. The modern concept of the knight is as an elite warrior sworn to uphold the values of chivalry, faith, loyalty, courage and honour. Knighthood as known in Medieval Europe was characterized by the combination of two elements: feudalism and service as a mounted combatant. Both arose under the reign of the Holy Roman Emperor Charlemagne, from which the knighthood of the Middle Ages can be seen to have had its genesis.

Portrait by August Köhler, c. 1910, after 1627 original

Johannes Kepler (/ˈkɛplər/; German: [joˈhanəs ˈkɛplɐ, -nɛs -] ^ⓘ; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae, influencing among others Isaac Newton, providing one of the foundations for his theory of universal gravitation. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural and modern science. He has been described as the "father of science fiction" for his novel Somnium.

Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, being named the father of modern optics, in particular for his Astronomiae pars optica. He also invented an improved version of the refracting telescope, the Keplerian telescope, which became the foundation of the modern refracting telescope, while also improving on the telescope design by Galileo Galilei, who mentioned Kepler's discoveries in his work. He is also known for postulating the Kepler conjecture. (Full article...)

What is the use of living, if it be not to strive for noble causes and to make this muddled world a better place for those who will live in it after we are gone?
