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...)

  No. 33 Squadron is a Royal Australian Air Force (RAAF) strategic transport and air-to-air refuelling squadron. It operates Airbus KC-30A Multi Role Tanker Transports from RAAF Base Amberley, Queensland. The squadron was formed in February 1942 for service during World War II, operating Short Empire flying boats and a variety of smaller aircraft. By 1944 it had completely re-equipped with Douglas C-47 Dakota transports, which it flew in New Guinea prior to disbanding in May 1946.
  
  The unit was re-established in February 1981 as a flight, equipped with two Boeing 707s for VIP and other long-range transport duties out of RAAF Base Richmond, New South Wales. No. 33 Flight was re-formed as a full squadron in July 1983. By 1988 it was operating six 707s, four of which were subsequently converted for aerial refuelling. The 707s saw active service during operations in Namibia, Somalia, the Persian Gulf, and Afghanistan. One of the transport jets was lost in a crash in October 1991. No. 33 Squadron relocated to Amberley and was temporarily without aircraft following the retirement of the 707s in June 2008. It began re-equipping with KC-30s in June 2011, and achieved initial operating capability with the type in February 2013. One of its aircraft was deployed to the Middle East in September 2014 as part of Operation Okra, Australia's contribution to the war against the Islamic State. The squadron maintained a KC-30 on Okra for the next six years, completing 1,440 air-to-air refuelling missions. (Full article...)

  GL Mk. II transmitter van

  
  Radar, Gun Laying, Mark I, or GL Mk. I for short, was a pre-World War II radar system developed by the British Army to provide range information to associated anti-aircraft artillery. There were two upgrades to the same basic system, GL/EF (Elevation Finder) and GL Mk. II, both of which added the ability to accurately determine bearing and elevation. The name refers to the radar's ability to direct the guns onto a target, known as gun laying.
  
  The first GL set was an elementary design developed from 1936 onward. Based on the early Chain Home radar's electronics, GL used separate transmitters and receivers located in wooden cabins mounted on gun carriages, each with its own antennas that had to be rotated to point at the target. The transmitted signal was quite wide, in a fan shape about 120 degrees across. This made it useful only for measuring slant range information; target bearing accuracy was approximately 20 degrees, and it could not provide any elevation information. Several were deployed with the British Expeditionary Force and at least one was captured by German forces during the Dunkirk evacuation. The subsequent German evaluation led them to believe that British radar was much less advanced than German radar. (Full article...)

  Henry Cornelius Burnett (October 25, 1825 – October 1, 1866) was an American politician who served as a Confederate States senator from Kentucky from 1862 to 1865. From 1855 to 1861, Burnett served four terms in the United States House of Representatives. A lawyer by profession, Burnett had held only one public office—circuit court clerk—before being elected to Congress. He represented Kentucky's 1st congressional district immediately prior to the Civil War. This district contained the entire Jackson Purchase region of the state, which was more sympathetic to the Confederate cause than any other area of Kentucky. Burnett promised the voters of his district that he would have President Abraham Lincoln arraigned for treason. Unionist newspaper editor George D. Prentice described Burnett as "a big, burly, loud-mouthed fellow who is forever raising points of order and objections, to embarrass the Republicans in the House".
  
  Besides championing the secession in Congress, Burnett also worked within Kentucky to bolster the state's support of the Confederacy. He presided over a sovereignty convention in Russellville in 1861 that formed a Confederate government for the state. The delegates to this convention chose Burnett to travel to Richmond, Virginia to secure Kentucky's admission to the Confederacy. Burnett also raised a Confederate regiment at Hopkinsville, Kentucky, and briefly served in the Confederate States Army. Camp Burnett, a Confederate recruiting post two miles west of Clinton in Hickman County, Kentucky, was named after him. (Full article...)

  Bust in the Louvre

  
  Domitian (/dəˈmɪʃən, -iən/ də-MISH-ən, -⁠ee-ən; Latin: Domitianus; 24 October 51 – 18 September 96) was Roman emperor from 81 to 96. The son of Vespasian and the younger brother of Titus, his two predecessors on the throne, he was the last member of the Flavian dynasty. Described as "a ruthless but efficient autocrat", his authoritarian style of ruling put him at sharp odds with the Senate, whose powers he drastically curtailed.
  
  Domitian had a minor and largely ceremonial role during the reigns of his father and brother. After the death of his brother, Domitian was declared emperor by the Praetorian Guard. His 15-year reign was the longest since Tiberius. As emperor, Domitian strengthened the economy by revaluing the Roman coinage, expanded the border defenses of the empire, and initiated a massive building program to restore the damaged city of Rome. Significant wars were fought in Britain, where his general Agricola made significant gains in his attempt to conquer Caledonia (Scotland), and in Dacia (Modern-day Romania), where Domitian was unable to achieve a decisive victory against King Decebalus. Domitian's government exhibited strong authoritarian characteristics. Religious, military, and cultural propaganda fostered a cult of personality, and by nominating himself as perpetual censor, he sought to control public and private morals. (Full article...)

  Cover of 1945 Princeton edition

  
  The Smyth Report (officially Atomic Energy for Military Purposes) is the common name of an administrative history written by American physicist Henry DeWolf Smyth about the Manhattan Project, the Allied effort to develop atomic bombs during World War II. The subtitle of the report is A General Account of the Development of Methods of Using Atomic Energy for Military Purposes. It was released to the public on August 12, 1945, just days after the atomic bombings of Hiroshima and Nagasaki on August 6 and 9.
  
  Smyth was commissioned to write the report by Major General Leslie R. Groves, Jr., the director of the Manhattan Project. The Smyth Report was the first official account of the development of the atomic bombs and the basic physical processes behind them. It also served as an indication as to what information was declassified; anything in the Smyth Report could be discussed openly. For this reason, the Smyth Report focused heavily on information, such as basic nuclear physics, which was either already widely known in the scientific community or easily deducible by a competent scientist, and omitted details about chemistry, metallurgy, and ordnance. This would ultimately give a false impression that the Manhattan Project was all about physics. (Full article...)

  RAAF area commands, November 1942. Eastern Area's boundaries remained in place until it re-formed as Home Command in October 1953, beginning the supersession of the area command system.

  
  Eastern Area Command was one of several geographically based commands raised by the Royal Australian Air Force (RAAF) during World War II. It was formed in May 1942, and controlled units located in New South Wales and southern Queensland. Headquartered in Sydney, Eastern Area Command's responsibilities included air defence, aerial reconnaissance and protection of the sea lanes within its boundaries. Its flying units operated fighters, reconnaissance bombers, and dive bombers, and concentrated on convoy escort, maritime patrol and anti-submarine warfare. The size of the area was such that the RAAF twice considered splitting it, but nothing came of this.
  
  The area command continued to function after the war, its headquarters transferring from Sydney to Glenbrook, in the Blue Mountains, in 1949. By this time, most of the RAAF's operational units—including fighter, bomber, and transport wings—were based within Eastern Area's boundaries, and the officer in command was responsible for air defence across all of Australia. In October 1953, the RAAF began reorganising its command-and-control system from one based on geography to one based on function; Eastern Area was re-formed as Home Command, which was renamed Operational Command in 1959, and Air Command in 1987.

  Issy Smith VC (18 September 1890 – 10 September 1940) was a British-Australian recipient of the Victoria Cross (VC), the highest award for gallantry in the face of the enemy that can be awarded to eligible forces of the Commonwealth and United Kingdom. In recognition of his VC, he was also awarded the French Croix de Guerre and Russian Cross of St. George (4th class) by the respective governments.
  
  Born Ishroulch Shmeilowitz (and other renderings), to parents residing in Turkey, Smith travelled to Britain as a child stowaway and enlisted in the British Army in 1904. He emigrated to Australia after he had transferred to the reserve, where he remained until mobilised as a reservist in 1914. As a corporal in the 1st Battalion, The Manchester Regiment, Smith was engaged in the Second Battle of Ypres. On 26 April 1915, Smith, on his own initiative, recovered wounded soldiers while exposed to sustained fire and attended to them "with the greatest devotion to duty regardless of personal risk". His conduct secured a recommendation for the Victoria Cross, which was awarded to Smith in August 1915. (Full article...)

  Portrait by Godfrey Kneller, c. 1690

  
  William III (William Henry; Dutch: Willem Hendrik; 4 November 1650 – 8 March 1702), also known as William of Orange, was the sovereign Prince of Orange from birth, Stadtholder of Holland, Zeeland, Utrecht, Guelders, and Overijssel in the Dutch Republic from 1672, and King of England, Ireland, and Scotland from 1689 until his death in 1702. He ruled Great Britain and Ireland with his wife, Queen Mary II, and their joint reign is known as that of William and Mary.
  
  William was the only child of William II, Prince of Orange, and Mary, Princess Royal, the daughter of King Charles I of England, Scotland, and Ireland. His father died a week before his birth, making William III the prince of Orange from birth. In 1677, he married his first cousin Mary, the elder daughter of his maternal uncle James, Duke of York, the younger brother and later successor of King Charles II. (Full article...)

  Looking north across the reserve

  
  Cley Marshes is a 176-hectare (430-acre) nature reserve on the North Sea coast of England just outside the village of Cley next the Sea, Norfolk. A reserve since 1926, it is the oldest of the reserves belonging to the Norfolk Wildlife Trust (NWT), which is itself the oldest county Wildlife Trust in the United Kingdom. Cley Marshes protects an area of reed beds, freshwater marsh, pools and wet meadows and is part of the North Norfolk Coast Site of Special Scientific Interest (SSSI), Special Area of Conservation (SAC), Special Protection Area (SPA), and Ramsar Site due to the large numbers of birds it attracts.
  
  The reserve is important for some scarce breeding species, such as pied avocets on the islands, and western marsh harriers, Eurasian bitterns and bearded reedlings in the reeds, and is also a major migration stopoff and wintering site. There are also several nationally or locally scarce invertebrates and plants specialised for this coastal habitat. It has five bird hides and an environmentally friendly visitor centre and further expansion is planned through the acquisition of neighbouring land and improvements to visitor facilities.

  The second Arab siege of Constantinople, as depicted in the 14th-century Bulgarian translation of the Manasses Chronicle

  
  In 717–718, Constantinople, the capital of the Byzantine Empire, was besieged by the Muslim Arabs of the Umayyad Caliphate. The campaign marked the culmination of twenty years of attacks and progressive Arab occupation of the Byzantine borderlands, while Byzantine strength was sapped by prolonged internal turmoil. In 716, after years of preparations, the Arabs, led by Maslama ibn Abd al-Malik, invaded Byzantine Asia Minor. The Arabs initially hoped to exploit Byzantine civil strife and made common cause with the general Leo III the Isaurian, who had risen up against Emperor Theodosius III. Leo, however, deceived them and secured the Byzantine throne for himself.
  
  After wintering in the western coastlands of Asia Minor, the Arab army crossed into Thrace in the early summer of 717 and built siege lines to blockade the city, which was protected by the massive Theodosian Walls. The Arab fleet, which accompanied the land army and was meant to complete the city's blockade by sea, was neutralized soon after its arrival by the Byzantine navy through the use of Greek fire. This allowed Constantinople to be resupplied by sea, while the Arab army was crippled by famine and disease during the unusually hard winter that followed. In spring 718, two Arab fleets sent as reinforcements were destroyed by the Byzantines after their Christian crews defected, and an additional army sent overland through Asia Minor was ambushed and defeated. Coupled with attacks by the Bulgars on their rear, the Arabs were forced to lift the siege on 15 August 718. On its return journey, the Arab fleet was almost completely destroyed by natural disasters. (Full article...)

  Vice-Admiral Sir Charles Richardson

  
  Vice-Admiral Sir Charles Richardson KCB (c. 10 March 1769 – 10 November 1850) was a Royal Navy officer of the 18th and 19th centuries. His naval career began when he joined HMS Vestal as a captain's servant in 1787. In Vestal he made an aborted journey to China before serving on the East Indies Station where he transferred to HMS Phoenix and fought in the Battle of Tellicherry and the Third Anglo-Mysore War in 1791 and 1792. Having returned to England as a master's mate, Richardson fought at the Glorious First of June on HMS Royal George in 1794 before being promoted to lieutenant in HMS Circe. In 1797, he successfully combated the Nore mutiny in Circe before fighting in the Battle of Camperdown where he personally captured the Dutch admiral Jan Willem de Winter. Afterwards he became flag lieutenant to Admiral Adam Duncan and fought at the Battle of Callantsoog and the Vlieter Incident in the Anglo-Russian invasion of Holland of 1799. He then sailed to Egypt in HMS Kent where he again went onshore, fighting in the battles of Abukir, Mandora, and Alexandria in 1801.
  
  Promoted to commander in July 1801, Richardson was given command of the en flute HMS Alligator. After the Napoleonic Wars began in 1803 he was sent to the Leeward Islands Station, where he captured three Dutch settlements in September. Richardson made a valuable contribution in the Battle of Suriname in the following year for which he was given command of HMS Centaur and promoted to post-captain. Leaving Centaur in 1805, at the start of the next year he received command of HMS Caesar. In Caesar Richardson fought at the battles of Les Sables-d'Olonne and the Basque Roads in 1809. He joined the Walcheren Campaign later in the year, where he took command of a naval brigade operating ashore. In 1810 he was given command of HMS Semiramis in the English Channel; cooperating with HMS Diana he fought an action against two French warships and a small convoy off the Gironde that was complimented by Spencer Perceval, the prime minister.

  George Washington (John Trumbull, 1780), with William Lee, Washington's enslaved personal servant

  
  The history of George Washington and slavery reflects Washington's changing attitude toward the ownership of human beings. The preeminent Founding Father of the United States and a hereditary slaveowner, Washington became uneasy with it, though kept the opinion in private communications only and continued the practice until his death. Slavery was then a longstanding institution dating back over a century in Virginia where he lived; it was also longstanding in other American colonies and in world history. Washington's will immediately freed one of his slaves, and required his remaining 123 slaves to serve his wife and be freed no later than her death; they ultimately became free one year after his own death.
  
  In the Colony of Virginia where Washington grew up, he became a third generation slave-owner at 11 years of age upon the death of his father in 1743, when he inherited his first ten slaves. In adulthood his personal slaveholding grew through inheritance, purchase, and the natural increase of children born into slavery. In 1759, he also gained control of dower slaves belonging to the Custis estate on his marriage to Martha Dandridge Custis. Washington's early attitudes about slavery reflected the prevailing Virginia planter views of the day, which included few moral qualms, if any. In 1774, Washington publicly denounced the slave trade on moral grounds in the Fairfax Resolves. After the Revolutionary War, he continued to own enslaved human beings, but supported the abolition of slavery by a gradual legislative process. (Full article...)

  Coin of Constantine III

  
  Constantine III (Latin: Flavius Claudius Constantinus; died shortly before 18 September 411) was a common Roman soldier who was declared emperor in Roman Britain in 407 and established himself in Gaul. He was recognised as co-emperor of the Roman Empire from 409 until 411.
  
  Constantine rose to power from within the field army of Roman Britain and was acclaimed emperor in early 407. He promptly moved to Gaul (modern France), taking all of the mobile troops from Britain, with their commander Gerontius, to confront bands of Germanic invaders who had crossed the Rhine the previous winter. With a mixture of fighting and diplomacy Constantine stabilised the situation and established control over Gaul and Hispania (modern Spain and Portugal), establishing his capital at Arles. The sitting emperor of the Western Roman Empire, Honorius, sent an army under Sarus the Goth to expel Constantine's forces. After initial victories, Sarus was repulsed. In Hispania, Honorius's relatives rose and expelled Constantine's administration. An army under the general Gerontius was sent to deal with this and Constantine's authority was re-established. In early 409 Honorius recognised Constantine as co-emperor. Constantine in turn raised his own oldest son to co-emperor as Constans II. (Full article...)

  SMS Kronprinz Wilhelm in Scapa Flow 1919

  
  SMS Kronprinz was the last dreadnought battleship of the four-ship König class of the German Imperial Navy. The battleship was laid down in November 1911 and launched on 21 February 1914. She was formally commissioned into the Imperial Navy on 8 November 1914, just over 3 months after the start of World War I. The name Kronprinz (Eng: "Crown Prince") refers to Crown Prince Wilhelm, and in June 1918, the ship was renamed Kronprinz Wilhelm in his honor. The battleship was armed with ten 30.5-centimeter (12 in) guns in five twin turrets and could steam at a top speed of 21 knots (39 km/h; 24 mph).
  
  Along with her three sister ships, König, Grosser Kurfürst and Markgraf, Kronprinz took part in most of the fleet actions during the war, including the Battle of Jutland on 31 May and 1 June 1916. Although near the front of the German line, she emerged from the battle unscathed. She was torpedoed by the British submarine HMS J1 on 5 November 1916 during an operation off the Danish coast. Following repairs, she participated in Operation Albion, an amphibious assault in the Baltic, in October 1917. During the operation Kronprinz engaged the Russian battleship Tsesarevich and forced her to retreat. (Full article...)

SBRs represented the pinnacle of gas mask development during the war, a mouthpiece connected via a hose to a box filter (hanging around the wearer's neck in this picture), which in turn contained granules of chemicals that neutralised the gas. The SBR was the prized possession of the ordinary infantryman; when the British were forced to retreat during the German Spring Offensive of 1918, it was found that while some troops had discarded their rifles, hardly any had left behind their respirators.

  A medieval ship flag captured by forces from Lübeck in the 1420s showed the arms of Denmark, Sweden, Norway and Pomerania. 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.

  Scars of a whipped slave named Peter, photo taken at Baton Rouge, Louisiana, 1863. In his own words, "Overseer Artayou Carrier whipped me. I was two months in bed sore from the whipping. My master come after I was whipped; he discharged the overseer." The slave pictured here escaped from a plantation in Mississippi, made his way to Union forces, and joined the U.S. Army at the Union garrison located at Baton Rouge.
  
  Slavery in the United States began soon after the English colonists first settled in North America. From about the 1640s until 1865, people of African descent were legally enslaved within the boundaries of the present U.S. mostly by whites, but also by a comparatively tiny number of American Indians and free blacks. By 1860, the slave population in the U.S. had grown to 4 million.

Enrico Fermi (Italian: [enˈriːko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian and naturalized American physicist, renowned for being the creator of the world's first artificial nuclear reactor, the Chicago Pile-1, and a member of the Manhattan Project. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of very few physicists to excel in both theoretical and experimental physics. Fermi was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and for the discovery of transuranium elements. With his colleagues, Fermi filed several patents related to the use of nuclear power, all of which were taken over by the US government. He made significant contributions to the development of statistical mechanics, quantum theory, and nuclear and particle physics.

Fermi's first major contribution involved the field of statistical mechanics. After Wolfgang Pauli formulated his exclusion principle in 1925, Fermi followed with a paper in which he applied the principle to an ideal gas, employing a statistical formulation now known as Fermi–Dirac statistics. Today, particles that obey the exclusion principle are called "fermions". Pauli later postulated the existence of an uncharged invisible particle emitted along with an electron during beta decay, to satisfy the law of conservation of energy. Fermi took up this idea, developing a model that incorporated the postulated particle, which he named the "neutrino". His theory, later referred to as Fermi's interaction and now called weak interaction, described one of the four fundamental interactions in nature. Through experiments inducing radioactivity with the recently discovered neutron, Fermi discovered that slow neutrons were more easily captured by atomic nuclei than fast ones, and he developed the Fermi age equation to describe this. After bombarding thorium and uranium with slow neutrons, he concluded that he had created new elements. Although he was awarded the Nobel Prize for this discovery, the new elements were later revealed to be nuclear fission products. (Full article...)
