The Historians' History of the World

History (derived from Ancient Greek ἱστορία (historía) 'inquiry; knowledge acquired by investigation') is the systematic study and documentation of the human past. History is an academic discipline which uses a narrative to describe, examine, question, and analyse past events, and investigate their patterns of cause and effect. Historians debate which narrative best explains an event, as well as the significance of different causes and effects. Historians debate the nature of history as an end in itself, and its usefulness in giving perspective on the problems of the present.

The period of events before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts or traditional oral histories, art and material artefacts, and ecological markers.

Stories common to a particular culture, but not supported by external sources (such as the tales surrounding King Arthur), are usually classified as cultural heritage or legends. History differs from myth in that it is supported by verifiable evidence. However, ancient cultural influences have helped create variant interpretations of the nature of history, which have evolved over the centuries and continue to change today. The modern study of history is wide-ranging, and includes the study of specific regions and certain topical or thematic elements of historical investigation. History is taught as a part of primary and secondary education, and the academic study of history is a major discipline in universities.

Herodotus, a 5th-century BCE Greek historian, is often considered the "father of history", as one of the first historians in the Western tradition, though he has been criticized as the "father of lies". Along with his contemporary Thucydides, he helped form the foundations for the modern study of past events and societies. Their works continue to be read today, and the gap between the culture-focused Herodotus and the military-focused Thucydides remains a point of contention or approach in modern historical writing. In East Asia a state chronicle, the Spring and Autumn Annals, was reputed to date from as early as 722 BCE, though only 2nd-century BCE texts have survived. The title "father of history" has also been attributed, in their respective societies, to Sima Qian, Ibn Khaldun, and Kenneth Dike. (Full article...)

  RAAF area command boundaries in 1944

  
  Area commands were the major operational and administrative formations of the Royal Australian Air Force (RAAF) between 1940 and 1954. Established in response to the outbreak of World War II, they underpinned the Air Force's geographically based command-and-control system for the duration of the conflict and into the early years of the Cold War, until being superseded by a functional control system made up of Home, Training, and Maintenance Commands.
  
  The area commands and their responsibilities evolved over time according to changing circumstances. The RAAF established four commands to begin with in 1940–41: Southern Area, Central Area, Western Area, and Northern Area. They oversaw most of the operations, training and maintenance within their boundaries. A concession to functional control occurred in mid-1941, when the Air Force formed two groups that assumed the training role of the southern and eastern states; Central Area was disbanded and most of its units taken over by Northern and Southern Areas, and the newly formed No. 2 (Training) Group. The area structure was further revised in 1942, following the outbreak of the Pacific War; Northern Area was split into North-Eastern Area and North-Western Area, and a new command, Eastern Area, was created, making a total of five commands. The same year, the RAAF formed two functional groups that assumed the maintenance role of the area commands; the latter focussed on operations until the end of hostilities. A new area command covering RAAF units in New Guinea, Northern Command, was formed in 1944 and dissolved soon after the war. (Full article...)

  Andrea Doria during World War II

  
  The Andrea Doria class (usually called Duilio class in Italian sources) was a pair of dreadnought battleships built for the Royal Italian Navy (Regia Marina) between 1912 and 1916. The two ships—Andrea Doria and Duilio—were completed during World War I. The class was an incremental improvement over the preceding Conte di Cavour class. Like the earlier ships, Andrea Doria and Duilio were armed with a main battery of thirteen 305-millimeter (12 in) guns.
  
  The two ships were based in southern Italy during World War I to help ensure that the Austro-Hungarian Navy's surface fleet would be contained in the Adriatic. Neither vessel saw any combat during the conflict. After the war, they cruised the Mediterranean and were involved in several international incidents, including at Corfu in 1923. In 1933, both ships were placed in reserve. In 1937 the ships began a lengthy reconstruction. The modifications included removing their center main battery turret and boring out the rest of the guns to 320 mm (12.6 in), strengthening their armor protection, installing new boilers and steam turbines, and lengthening their hulls. The reconstruction work lasted until 1940, by which time Italy was already engaged in World War II. (Full article...)

  King Henry VI, who probably organized the Loveday in an attempt to pacify his nobility, which by 1458, had divided down clear partisan lines into armed camps.

  
  The Loveday of 1458 (also known as the Annunciation Loveday) was a ritualistic reconciliation between warring factions of the English nobility that took place at St Paul's Cathedral on 25 March 1458. Following the outbreak of the Wars of the Roses in 1455, it was the culmination of lengthy negotiations initiated by King Henry VI to resolve the lords' rivalries. English politics had become increasingly factional during his reign, and was exacerbated in 1453 when he became catatonic. This effectively left the government leaderless, and eventually the King's cousin, and at the time heir to the throne, Richard, Duke of York, was appointed Protector during the King's illness. Alongside York were his allies from the politically and militarily powerful Neville family, led by Richard, Earl of Salisbury, and his eldest son, Richard, Earl of Warwick. When the King returned to health a year later, the protectorship ended but partisanship within the government did not.
  
  Supporters of King Henry and his Queen, Margaret of Anjou, have been loosely called "Lancastrians", the King being head of the House of Lancaster, while the duke and his party are considered "Yorkists", after his title of Duke of York. By the 1450s, York felt increasingly excluded from government, and, in May 1455—possibly fearing an ambush by his enemies—led an army against the King at the First Battle of St Albans. There, in what has been called more of a series of assassinations than a battle, the personal enemies of York and the Nevilles—the Duke of Somerset, the Earl of Northumberland, and Lord Clifford—perished.

  The Dionysus Cup, a kylix painted by the Athenian Exekias around 530 BCE, possibly showing the narrative of the seventh Homeric Hymn

  
  The Homeric Hymns (Ancient Greek: Ὁμηρικοὶ ὕμνοι, romanised: Homērikoì húmnoi) are a collection of thirty-three ancient Greek hymns and one epigram. The hymns praise deities of the Greek pantheon and retell mythological stories, often involving a deity's birth, their acceptance among the gods on Mount Olympus, or the establishment of their cult. In antiquity, the hymns were generally, though not universally, attributed to the poet Homer: modern scholarship has established that most date to the seventh and sixth centuries BCE, though some are more recent and the latest, the Hymn to Ares, may have been composed as late as the fifth century CE.
  
  The Homeric Hymns share compositional similarities with the Iliad and the Odyssey, also traditionally attributed to Homer. They share the same artificial literary dialect of Greek, are composed in dactylic hexameter, and make use of short, repeated phrases known as formulae. It is unclear how far writing, as opposed to oral composition, was involved in their creation. They may initially have served as preludes to the recitation of longer poems, and have been performed, at least originally, by singers accompanying themselves on a lyre or another stringed instrument. Performances of the hymns may have taken place at sympotic banquets, religious festivals and royal courts. (Full article...)

  Shigi Qutuqu (Mongolian: ᠰᠢᠭᠢᠬᠤᠲᠤᠭ; c. 1178–1260) was a high-ranking official during the early decades of the Mongol Empire. The adopted son of the empire's founder Temüjin (later entitled Genghis Khan) and his wife Börte, Shigi Qutuqu played an important role in the codification of Mongol law, serving with distinction as an administrator in North China. He may also have been a major source for the Secret History of the Mongols, which portrays him very favourably.
  
  Although the Secret History states that Shigi Qutuqu was adopted by Hö'elün, Temüjin's mother, chronological inconsistencies make this account improbable. The foundling was brought up in Temüjin's household and was one of the first Mongols to become literate. The Secret History exaggerates his role in the years after the empire's foundation, but Shigi Qutuqu was nevertheless appointed to several high-ranking legal positions, in which he served during the Mongol conquest of the Jin dynasty. He was the commander during the only Mongol defeat of the western campaign against Khwarazmia, being overcome by Jalal al-Din at the 1221 Battle of Parwan. (Full article...)

  Thomas Baker as a cadet pilot c.1917

  
  Thomas Charles Richmond Baker, DFC, MM & Bar (2 May 1897 – 4 November 1918) was an Australian soldier, aviator, and flying ace of the First World War. Born in Smithfield, South Australia, he was an active sportsman in his youth and developed a keen interest in aviation. He was employed as a clerk with the Bank of New South Wales, before he enlisted in the Australian Imperial Force in July 1915, for service in World War I. Posted to an artillery unit on the Western Front, he was awarded the Military Medal for carrying out numerous repairs on a communications line while subject to severe artillery fire. In June 1917, Baker was awarded a bar to his decoration for his part in quelling a fire in one of the artillery gun pits that was endangering approximately 300 rounds of shrapnel and high explosive.
  
  In September 1917, Baker applied for a position as a mechanic in the Australian Flying Corps. He was instead selected for flight training, and was posted to courses in the United Kingdom. He graduated as a pilot and was commissioned a second lieutenant in March 1918. Posted for active duty in France that June, Baker joined the ranks of No. 4 Squadron AFC. Over the next four months, he rose to the rank of captain and was credited with bringing down 12 German aircraft. He was shot down and killed on 4 November 1918. In February 1919, he was posthumously awarded the Distinguished Flying Cross. (Full article...)

  Battle of Öland by Claus Møinichen

  
  The Battle of Öland was a naval battle between an allied Danish-Dutch fleet and the Swedish navy in the Baltic Sea, off the east coast of Öland on 1 June 1676. The battle was a part of the Scanian War (1675–79) fought for supremacy over the southern Baltic. Sweden was in urgent need of reinforcements for its north German possessions; Denmark sought to ferry an army to Scania in southern Sweden to open a front on Swedish soil.
  
  Just as the battle began, the Swedish flagship Kronan sank, taking with it almost the entire crew, including the Admiral of the Realm and commander of the Swedish navy, Lorentz Creutz. The allied force under the leadership of the Dutch admiral Cornelis Tromp took full advantage of the ensuing disorder on the Swedish side. The acting commander after Creutz's sudden demise, Admiral Claes Uggla, was surrounded and his flagship Svärdet battered in a drawn-out artillery duel, then set ablaze by a fire ship. Uggla drowned while escaping the burning ship, and with the loss of a second supreme commander, the rest of the Swedish fleet fled in disorder. (Full article...)

  HMAS Melbourne in 1967

  
  HMAS Melbourne (R21) was a Majestic-class light aircraft carrier operated by the Royal Australian Navy (RAN) from 1955 until 1982, and was the third and final conventional aircraft carrier to serve in the RAN. Melbourne was the only Commonwealth naval vessel to sink two friendly warships in peacetime collisions.
  
  Melbourne was laid down for the Royal Navy as the lead ship of the Majestic class in April 1943, and was launched as HMS Majestic (R77) in February 1945. At the end of the Second World War, work on the ship was suspended until she was purchased by the RAN in 1947. At the time of purchase, it was decided to incorporate new aircraft carrier technologies into the design, making Melbourne the third ship to be constructed with an angled flight deck. Delays in construction and integrating the enhancements meant that the carrier was not commissioned until 1955. (Full article...)

  Battle of Lissa, 13 March 1811, Nicholas Pocock

  
  The Battle of Lissa, also known as the Battle of Vis (French: Bataille de Lissa; Italian: Battaglia di Lissa; Croatian: Viška bitka), was a naval action fought between a British frigate squadron and a much larger squadron of French and Italian frigates and smaller vessels on Wednesday, 13 March on 1811 during the Adriatic campaign of the Napoleonic Wars. The engagement was fought in the Adriatic Sea for possession of the strategically important Croatian island of Vis (Lissa in Italian), from which the British squadron had been disrupting French shipping in the Adriatic. The French needed to control the Adriatic to supply a growing army in the Illyrian Provinces, and consequently dispatched an invasion force in March 1811 consisting of six frigates, numerous smaller craft and a battalion of Italian soldiers.
  
  The French invasion force under Bernard Dubourdieu was met by Captain William Hoste and his four ships based on the island. In the subsequent battle, Hoste sank the French flagship, captured two others, and scattered the remainder of the Franco-Venetian squadron. The battle has been hailed as an important British victory, due to both the disparity between the forces and the signal raised by Hoste, a former subordinate of Horatio Nelson. Hoste had raised the message "Remember Nelson" as the French bore down, and had then manoeuvred to drive Dubourdieu's flagship ashore and scatter his squadron in what has been described as "one of the most brilliant naval achievements of the war".

  The Ming dynasty, officially the Great Ming, was an imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol-led Yuan dynasty. The Ming dynasty was the last imperial dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump regimes ruled by remnants of the Ming imperial family—collectively called the Southern Ming—survived until 1662.
  
  The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the navy's dockyards in Nanjing were the largest in the world. He also took great care breaking the power of the court eunuchs and unrelated magnates, enfeoffing his many sons throughout China and attempting to guide these princes through the Huang-Ming Zuxun, a set of published dynastic instructions. This failed when his teenage successor, the Jianwen Emperor, attempted to curtail his uncle's power, prompting the Jingnan campaign, an uprising that placed the Prince of Yan upon the throne as the Yongle Emperor in 1402. The Yongle Emperor established Yan as a secondary capital and renamed it Beijing, constructed the Forbidden City, and restored the Grand Canal and the primacy of the imperial examinations in official appointments. He rewarded his eunuch supporters and employed them as a counterweight against the Confucian scholar-bureaucrats. One eunuch, Zheng He, led seven enormous voyages of exploration into the Indian Ocean as far as Arabia and the eastern coasts of Africa. Hongwu and Yongle emperors had also expanded the empire's rule into Inner Asia. (Full article...)

  Nichols's Missouri Cavalry Regiment served in the Confederate States Army during the late stages of the American Civil War. The cavalry regiment began recruiting in early 1864 under Colonel Sidney D. Jackman, who had previously raised a unit that later became the 16th Missouri Infantry Regiment. The regiment officially formed on June 22 and operated against the Memphis and Little Rock Railroad through August. After joining Major General Sterling Price's command, the unit participated in Price's Raid, an attempt to create a popular uprising against Union control of Missouri and draw Union troops away from more important theaters of the war. During the raid, while under the command of Lieutenant Colonel Charles H. Nichols, the regiment was part of an unsuccessful pursuit of Union troops who were retreating after the Battle of Fort Davidson in late September.
  
  At the Battle of Little Blue River on October 21, Nichols's regiment attacked the Union flank, drawing artillery from the Union center to counter the regiment's attack. This allowed other Confederate units to successfully attack the now-weakened Union center. The next day, the regiment was part of a force that defeated the 2nd Kansas Militia Infantry Regiment during the Battle of Byram's Ford. On October 23, Nichols's regiment was engaged in the Confederate defeat at the Battle of Westport. After the defeat at Westport, the Confederates began retreating through Kansas. After a disastrous defeat at the Battle of Mine Creek on October 25, Nichols's regiment was part of the Confederate rear guard. The unit supported an artillery battery during the Second Battle of Newtonia on October 28, but did not see close combat. The men of Nichols's regiment were furloughed on October 30, with orders to return to the army in December. Before the war ended in 1865, the unit disbanded, probably while stationed in Texas; some of the men reported to Shreveport, Louisiana, in June to receive their paroles. The regiment had a strength of about 300 men in August 1864 and the number of casualties suffered by the regiment over the course of its existence cannot be accurately determined. (Full article...)

  The first illustration of the first roll of the Anthony Roll, depicting the Henry Grace à Dieu, the largest ship in the English navy during the reign of King Henry VIII.

  
  The Anthony Roll is a written record of ships of the English Tudor navy of the 1540s, named after its creator, Anthony Anthony. It originally consisted of three rolls of vellum, depicting 58 naval vessels along with information on their size, crew, armament, and basic equipment. The rolls were presented to King Henry VIII in 1546, and were kept in the royal library. In 1680 King Charles II gave two of the rolls to Samuel Pepys, who had them cut up and bound as a single volume book, which is now in the Pepys Library at Magdalene College, Cambridge. The third roll remained in the royal collection until it was given by King William IV to his daughter Lady Mary Fox, who sold it to the British Museum in 1858; it is now owned by the British Library.
  
  The Anthony Roll is the only known fully illustrated inventory of ships of the English navy in the Tudor period. As the work of a successful state official in 16th century England, the artistic value of the Anthony Roll has been described as being characterised by "naive draughtsmanship and conformity to a pattern" though its artistic aspects display "a decent amateur grasp of form and colour". While the inventories listed in its text have proven to be highly accurate, most of the ship illustrations are rudimentary and made according to a set formula. The level of detail of the ship design, armament and especially rigging has therefore proven to be only approximate. Nevertheless, through their depiction of the ceremonial ornamentation the illustrations in the Roll have provided relevant secondary information to the study of Tudor period heraldry, flags and ship ornamentation.

  The pyrocumulus cloud produced by the explosion

  
  On the morning of 6 December 1917, the French cargo ship SS Mont-Blanc collided with the Norwegian vessel SS Imo in the harbour of Halifax, Nova Scotia, Canada. Mont-Blanc, laden with high explosives, caught fire and exploded, devastating the Richmond district of Halifax. At least 1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time. It released the equivalent energy of roughly 2.9 kilotons of TNT (12 TJ).
  
  Mont-Blanc was under orders from the French government to carry her cargo from New York City via Halifax to Bordeaux, France. At roughly 8:45 am, she collided at low speed, approximately one knot (1.2 mph or 1.9 km/h), with the unladen Imo, chartered by the Commission for Relief in Belgium to pick up a cargo of relief supplies in New York. On Mont-Blanc, the impact damaged benzol barrels stored on deck, causing them to leak vapours which were ignited by sparks from the collision, setting off a fire on board that quickly grew out of control. Approximately 20 minutes later at 9:04:35 am, Mont-Blanc exploded. (Full article...)

  The battle of Agua Dulce Creek was a skirmish during the Texas Revolution between Mexican troops and the colonists of the Mexican province of Texas, known as Texians. As part of the Goliad Campaign to retake the Texas Gulf Coast, Mexican troops ambushed a group of Texians on March 2, 1836. The skirmish began approximately 26 miles (42 km) south of San Patricio, in territory belonging to the Mexican state of Tamaulipas.
  
  When Mexico transitioned to a centralized government in 1835, supporters of federalism took up arms. Colonists in Texas revolted in October 1835 and by the end of the year had expelled all Mexican troops from their province. With hostilities temporarily suspended, Frank W. Johnson, the commander of the volunteer army in Texas, and James Grant gathered volunteers for a planned invasion of the Mexican port town of Matamoros. In late February 1836, Johnson and half of the volunteers drove a herd of horses to San Patricio, while Grant took the remaining men to gather more horses and to attempt contact with federalist sympathizers near Matamoros.

  The Battle of Mount Austen, the Galloping Horse, and the Sea Horse, part of which is sometimes called the Battle of the Gifu, took place from 15 December 1942 to 23 January 1943 and was primarily an engagement between United States and Imperial Japanese forces in the hills near the Matanikau River area on Guadalcanal during the Guadalcanal campaign. The U.S. forces were under the overall command of Major General Alexander Patch and the Japanese forces were under the overall command of Lieutenant General Harukichi Hyakutake.
  
  In the battle, U.S. soldiers and Marines, assisted by native Solomon Islanders, attacked Imperial Japanese Army forces defending well-fortified and entrenched positions on several hills and ridges. The most prominent hills were called Mount Austen, the Galloping Horse, and the Sea Horse by the Americans. The U.S. was attempting to destroy the Japanese forces on Guadalcanal, and the Japanese were trying to hold their defensive positions until reinforcements could arrive. (Full article...)

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.

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

Masako Katsura (桂 マサ子, Katsura Masako, listen; 7 March 1913 – 20 December 1995), nicknamed "Katsy" and sometimes called the "First Lady of Billiards", was a Japanese carom billiards player who was most active in the 1950s. She was the first woman to compete and place among the best in the male-dominated world of professional billiards. First learning the game from her brother-in-law and then under the tutelage of Japanese champion Kinrey Matsuyama, Katsura became Japan's only female professional player. In competition in Japan, she took second place in the country's national three-cushion billiards championship three times. In exhibition she was noted for running 10,000 points at the game of straight rail.

After marrying a U.S. Army non-commissioned officer in 1950, Katsura emigrated to the United States in 1951. There she was invited to play in the 1952 U.S.-sponsored World Three-Cushion Championship, ultimately taking seventh place at that competition. Katsura was the first woman ever to be included in any world billiards tournament. Her fame cemented, Katsura went on an exhibition tour of the United States with eight-time world champion Welker Cochran, and later with 51-time world champion Willie Hoppe. In 1953 and 1954, she again competed for the world three-cushion crown, taking fifth and fourth places respectively. (Full article...)

Selected quote

What we find in books is like the fire in our hearths. We fetch it from our neighbors, we kindle it at home, we communicate it to others, and it becomes the property of all.
