The Historians' History of the World

History is the systematic study of the past. As an academic discipline, it analyzes and interprets evidence to construct narratives about what happened and explain why it happened, focusing primarily on the human past. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a slightly different sense, the term history refers not to an academic field but to the past itself or to individual texts about the past.

Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians integrate the perspectives of several individual sources to develop a coherent narrative. Different schools of thought, such as positivism, the Annales school, Marxism, and postmodernism, have distinct methodological approaches.

History is a broad discipline encompassing many branches. Some focus on specific time periods, such as ancient history, while others concentrate on particular geographic regions, such as the history of Africa. Thematic categorizations include political history, social history, and economic history. Branches associated with specific research methods include quantitative history, comparative history, and oral history.

History emerged as a field of inquiry in the ancient period to replace myth-infused narratives, with influential early traditions originating in Greece, China, and later also 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...)

  Bohr in 1922

  
  Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
  
  Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. (Full article...)

  The battle of Babylon Hill was an indecisive skirmish that took place between Royalist and Parliamentarian forces near Yeovil, in South West England, on 7 September 1642, during the early stages of the First English Civil War. The engagement occurred after a failed Parliamentarian siege of nearby Royalist-held Sherborne. After the Parliamentarians had retreated to Yeovil, a force of around 350 Royalists was sent to reconnoitre their movements. Under the command of Sir Ralph Hopton, the Royalist detachment established itself on Babylon Hill, on the outskirts of Yeovil.
  
  Around half an hour before sunset, the Royalists decided to withdraw and began marching their infantry off the hill. As they were doing so, they spotted Parliamentarian soldiers approaching, and Hopton hurriedly recalled the infantry and set his men to meet the attack. The battle became chaotic, mostly due to the inexperience of the soldiers involved. The Parliamentarian force, which also numbered around 350, made a three-pronged cavalry attack, which the Royalists were able to repel, though sections of both forces were routed. In the confusion, they were eventually able to pull back under the cover of darkness. (Full article...)

  Lithograph of Weissenburg in 1902

  
  SMS Weissenburg was one of the first ocean-going battleships of the Imperial German Navy. She was the third pre-dreadnought of the Brandenburg class, which also included her sister ships Brandenburg, Wörth, and Kurfürst Friedrich Wilhelm. Weissenburg was laid down in 1890 in the AG Vulcan dockyard in Stettin, launched in 1891, and completed in 1894. The Brandenburg-class battleships were unique for their era in that they carried six large-caliber guns in three twin turrets, as opposed to four guns in two turrets, as was the standard in other navies.
  Weissenburg served with I Division during the first decade of her service with the fleet. This period was generally limited to training exercises and goodwill visits to foreign ports. These training maneuvers were nevertheless very important to developing German naval tactical doctrine in the two decades before World War I, especially under the direction of Alfred von Tirpitz. Weissenburg, along with her three sisters, saw only one major overseas deployment during this period, to China in 1900–1901, during the Boxer Uprising. The ship underwent a major modernization in 1904–1905. (Full article...)

  Colonel John Wilton in Morotai, September 1945

  
  General Sir John Gordon Noel Wilton, KBE, CB, DSO (22 November 1910 – 10 May 1981) was a senior commander in the Australian Army. He served as Chief of the General Staff (CGS), the Army's professional head, from 1963 until 1966, and as Chairman of the Chiefs of Staff Committee (CCOSC), forerunner of the role of Australia's Chief of the Defence Force, from 1966 until 1970. His eight-year tenure as senior officer of first the Army and then the Australian military spanned almost the entire period of the nation's involvement in the Vietnam War.
  
  Born in Sydney, Wilton entered the Royal Military College, Duntroon, in 1927. Owing to lack of opportunity in the Australian military at the time, he took a commission in the British Army following his graduation in 1930. He spent most of the remainder of the decade with the Royal Artillery in India. Wilton returned to Australia on the eve of World War II and was commissioned into the Royal Australian Artillery. He saw action with the 7th Division in Syria and the 3rd Division in New Guinea, earning a mention in despatches in the former campaign and the Distinguished Service Order in the latter. Finishing the war a temporary colonel, he was appointed an Officer of the Order of the British Empire in 1947. Wilton was posted to Korea in 1953 to take command of the 28th Commonwealth Brigade, leading it in its final action of the war in July. He was raised to Commander of the Order of the British Empire and awarded the US Legion of Merit for his performance in Korea. (Full article...)

  A former French AMX-30B at the U.S. Army Armor & Cavalry Collection

  
  The AMX-30 is a main battle tank designed by Ateliers de construction d'Issy-les-Moulineaux (AMX, then GIAT) and first delivered to the French Army in August 1966. The first five tanks were issued to the 501st Régiment de Chars de Combat (Tank Regiment) in August of that year. The production version of the AMX-30B weighed 36 metric tons (40 short tons), and sacrificed protection for increased mobility. The French believed that it would have required too much armour to protect against the latest anti-tank threats, thereby reducing the tank's maneuverability. Protection, instead, was provided by the speed and the compact dimensions of the vehicle, including a height of 2.28 metres. It had a 105 mm gun, firing a then advanced high-explosive anti-tank (HEAT) warhead known as the Obus G. The Obus G used an outer shell, separated from the main charge by ball bearings, to allow the round to be spin stabilized by the gun without spinning the warhead inside which would disrupt jet formation. Mobility was provided by the 720 horsepower (540 kW) HS-110 diesel engine, although the troublesome transmission adversely affected the tank's performance.
  
  In 1979, due to issues caused by the transmission, the French Army began to modernize its fleet of tanks to AMX-30B2 standards, which included a new transmission, an improved engine and the introduction of a new OFL 105 F1 fin-stabilized kinetic energy penetrator. Production of the AMX-30 also extended to a number of variants, including the AMX-30D armoured recovery vehicle, the AMX-30R anti-aircraft gun system, a bridge-layer, the Pluton tactical nuclear missile launcher and a surface-to-air missile launcher.

  Workers leaving the Manhattan Project's Y-12 plant on 11 August 1945

  
  The Clinton Engineer Works (CEW) was the production installation of the Manhattan Project that during World War II produced the enriched uranium used in the 1945 bombing of Hiroshima, as well as the first examples of reactor-produced plutonium. It consisted of production facilities arranged at three major sites, various utilities including a power plant, and the town of Oak Ridge. It was in East Tennessee, about 18 miles (29 km) west of Knoxville, and was named after the town of Clinton, eight miles (13 km) to the north. The production facilities were mainly in Roane County, and the northern part of the site was in Anderson County. The Manhattan District Engineer, Kenneth Nichols, moved the Manhattan District headquarters from Manhattan to Oak Ridge in August 1943. During the war, CEW's advanced research was managed for the government by the University of Chicago.
  
  Construction workers were housed in a community known as Happy Valley. Built by the Army Corps of Engineers in 1943, this temporary community housed 15,000 people. The township of Oak Ridge was established to house the production staff. The operating force peaked at 50,000 workers just after the end of the war. The construction labor force peaked at 75,000, and the combined employment peak was 80,000. The town was developed by the federal government as a segregated community; Black Americans lived only in an area known as Gamble Valley, in government-built "hutments" (one-room shacks) on the south side of what is now Tuskegee Drive.

  Greatest extent of the Western Chalukya Empire, 1121 AD

  
  The Western Chalukya Empire (/tʃəˈluːkjə/ chə-LOO-kyə) ruled most of the western Deccan, South India, between the 10th and 12th centuries. The dynasty is sometimes called the Kalyani Chalukya after its regal capital at Kalyani, today's Basavakalyan in the modern Bidar district of Karnataka state, and alternatively the Later Chalukya from its theoretical relationship to the 6th-century Chalukya dynasty of Badami. The dynasty is called Western Chalukyas to differentiate from the contemporaneous Eastern Chalukyas of Vengi, a separate dynasty. Before the rise of these Chalukyas, the Rashtrakuta Empire of Manyakheta controlled most of the Deccan Plateau and Central India for over two centuries. In 973, seeing confusion in the Rashtrakuta empire after a successful invasion of their capital by the ruler of the Paramara dynasty of Malwa, Tailapa II, a feudatory of the Rashtrakuta dynasty ruling from Bijapur region defeated his overlords and made Manyakheta his capital. The dynasty quickly rose to power and grew into an empire under Someshvara I who moved the capital to Kalyani.
  
  For over a century, the two empires of South India, the Western Chalukyas and the Chola dynasty of Thanjavur fought many fierce wars to control the fertile region of Vengi. During these conflicts, the Eastern Chalukyas of Vengi, distant cousins of the Western Chalukyas but related to the Cholas by marriage, took sides with the Cholas further complicating the situation. During the rule of Vikramaditya VI, in the late 11th and early 12th centuries, the Western Chalukyas convincingly contended with the Cholas and reached a peak, ruling territories that spread over most of the Deccan, between the Narmada River in the north and Kaveri River in the south. His exploits were not limited to the south for even as a prince, during the rule of Someshvara I, he had led successful military campaigns as far east as modern Bihar and Bengal. During this period the other major ruling families of the Deccan, the Hoysala Empire, the Seuna dynasty, the Kakatiya dynasty and the Kalachuris of Kalyani, were subordinates of the Western Chalukyas and gained their independence only when the power of the Chalukya waned during the later half of the 12th century.

  Jean Bart in 1914

  
  Jean Bart was the second of four Courbet-class battleships, the first dreadnoughts built for the French Navy. She was completed before World War I as part of the 1910 naval building programme. She spent the war in the Mediterranean and helped to sink the Austro-Hungarian protected cruiser Zenta on 16 August 1914. She was torpedoed by an Austro-Hungarian submarine in December and steamed to Malta for repairs that required three and a half months. She spent the rest of the war providing cover for the Otranto Barrage that blockaded the Austro-Hungarian Navy in the Adriatic Sea and sometimes served as a flagship.
  
  After the war, she and her sister ship France participated in the occupation of Constantinople and were then sent to the Black Sea in 1919 to support Allied troops in the Southern Russia Intervention. Jean Bart's war-weary crew briefly mutinied, but it was easily put down and she returned to France mid-year. She was partially modernised twice during the 1920s, but was deemed to be in too poor condition to be refitted again in the 1930s. Therefore, she became a training ship in 1934 and was then disarmed and hulked as an accommodation ship in 1935–1936 in Toulon. The Germans captured her intact when they occupied Toulon in 1942 and used her for testing large shaped charge warheads. She was sunk by Allied bombing in 1944, and after the war ended, was refloated and scrapped beginning in late 1945. (Full article...)

  Yamashiro on her trials, 19 December 1916

  
  The Fusō-class battleships (扶桑型戦艦, Fusō-gata senkan) were a pair of dreadnought battleships built for the Imperial Japanese Navy (IJN) before World War I and completed during the war. Both patrolled briefly off the coast of China before being placed in reserve at the war's end. In 1922, Yamashiro became the first battleship in the IJN to successfully launch aircraft.
  
  During the 1930s, both ships underwent a series of modernizations and reconstructions. Fusō was modernized in two phases (1930–33, 1937–41), while Yamashiro was reconstructed from 1930 to 1935. The modernization increased their armor, replaced and upgraded their machinery, and rebuilt their superstructures into a distinctive pagoda mast style. Despite the expensive reconstructions, both vessels were obsolescent by World War II, and neither saw significant action in the early years of the war. Fusō served as a troop transport in 1943, while Yamashiro was relegated to training duty in the Inland Sea. Both received better anti-aircraft weapons in 1944 before transferring to Singapore in August 1944. (Full article...)

  SMS Kaiser Wilhelm der Grosse, c. 1903

  
  SMS Kaiser Wilhelm der Grosse ("HMS Emperor William the Great") was a German pre-dreadnought battleship of the Kaiser Friedrich III class, built around the turn of the 20th century. The ship was one of the first battleships built by the German Imperial Navy (Kaiserliche Marine) as part of a program of naval expansion under Kaiser Wilhelm II. Kaiser Wilhelm der Grosse was built in Kiel at the Germaniawerft shipyard. She was laid down in January 1898, launched in June 1899, and completed in May 1901. The ship was armed with a main battery of four 24-centimeter (9.4 in) guns in two twin turrets.
  Kaiser Wilhelm der Grosse served in the main fleet—the Heimatflotte (Home Fleet) and later the Hochseeflotte (High Seas Fleet)—for the first seven years of her career. She participated in several of the fleet's training cruises and maneuvers, primarily in the North and Baltic Seas. Her peacetime career was relatively uneventful and she suffered no accidents. She was decommissioned for a major reconstruction in 1908–10, after which she was assigned to the Reserve Division with her four sister ships, all of which were essentially obsolete by that time.

  The Gudovac massacre was the mass killing of around 190 Bjelovar Serbs by the Croatian nationalist Ustaše movement on 28 April 1941, during World War II. The massacre occurred shortly after the German-led Axis invasion of Yugoslavia and the establishment of the Ustaše-led Axis puppet state known as the Independent State of Croatia (NDH). It was the first act of mass murder committed by the Ustaše upon coming to power, and presaged a wider Ustaše-perpetrated campaign of genocide against Serbs in the NDH that lasted until the end of the war.
  
  The Ustaše used the mysterious deaths of two of their local followers as a pretext for the killings. The victims were drawn from Gudovac and its surroundings on 28 April. Most were arrested under the guise that they were rebels loyal to the ousted Yugoslav government. They were taken to a nearby field and collectively shot by a firing squad of up to 70 Ustaše guards. Five of the prisoners managed to survive the initial volley and crawled away to safety. The Ustaše forced Gudovac's surviving inhabitants to dig a mass grave for the victims and pour quicklime on the bodies to speed up decomposition. The following day, relatives of one of the victims informed the Germans of what had transpired. The Germans ordered a partial exhumation of the mass grave, and had 40 suspected perpetrators arrested. Mladen Lorković, a senior Ustaše official, used his influence to have the detained men released and promised German ambassador Siegfried Kasche that the Croatian authorities would carry out a thorough investigation. No investigation took place. (Full article...)

  No. 1 Squadron is a Royal Australian Air Force (RAAF) squadron headquartered at RAAF Base Amberley, Queensland. It is controlled by No. 82 Wing, part of Air Combat Group, and is equipped with Boeing F/A-18F Super Hornet multi-role fighters.
  
  The squadron was formed under the Australian Flying Corps in 1916 and saw action in the Sinai and Palestine campaigns during World War I. It flew obsolete Royal Aircraft Factory B.E.2s, B.E.12s, Martinsyde G.100s and G.102s, as well as Airco DH.6s, Bristol Scouts and Nieuport 17s, before re-equipping with the R.E.8 in October 1917 and finally the Bristol Fighter in December. Its commanding officer in 1917–18 was Major Richard Williams, later known as the "Father of the RAAF". Disbanded in 1919, No. 1 Squadron was re-formed on paper as part of the RAAF in 1922, and re-established as an operational unit three years later. Initially a composite formation of Airco DH.9s and Royal Aircraft Factory S.E.5s, it took on a specialist bomber role in the 1930s, flying mainly Hawker Demons but also Westland Wapitis and Bristol Bulldogs, before re-equipping with Avro Ansons on the eve of World War II.

  The FitzWalter coat of arms: d'or ung fece entre deux cheverons de goules ('Or, a fess gules between two chevrons of the last'). The arms are a differenced version of those of de Clare, the senior branch of the family.

  
  
  John FitzWalter, 2nd Baron FitzWalter (Fitzwalter or Fitz Wauter; c. 1315 – 18 October 1361) was an English baron and gang leader in the 14th-century. He was a prominent Essex landowner best known for his criminal activities, particularly around Colchester. His family was of a noble and ancient lineage, with connections to the powerful de Clare family, who had arrived in England at the time of the Norman Conquest. The FitzWalters held estates across Essex, as well as properties in London and Norfolk. John FitzWalter played a prominent role during the early years of King Edward III's wars in France, and at some point, FitzWalter was married to Eleanor Percy, the daughter of Henry, Lord Percy.
  
  FitzWalter built a strong affinity around him, mainly from among leading members of the county's gentry, but also including men from elsewhere, such as a Norfolk parson. At their head, FitzWalter waged an armed campaign against the neighbouring town of Colchester, almost from the moment he reached adulthood. The townsmen seem to have exacerbated the dispute by illegally entering FitzWalter's park in Lexden; in return, FitzWalter banned them from one of their own watermills and then, in 1342, he besieged the town, preventing anyone entering or leaving for some weeks, as well as ransacking much property and destroying the market. One historian has described him, in his activities, as the medieval equivalent of a 20th-century American racketeer. Other victims of his Essex gang were local jurors, royal officials, a man forced to abjure the realm, and the prior of Little Dunmow Abbey. (Full article...)
• 
  Muhammad II (Arabic: محمد الثاني) (also known by the epithet al-Faqih, "the canon-lawyer", c. 1235 – 8 April 1302; reigned from 1273 until his death) was the second Nasrid ruler of the Emirate of Granada in Al-Andalus on the Iberian Peninsula, succeeding his father, Muhammad I. Already experienced in matters of state when he ascended the throne, he continued his father's policy of maintaining independence in the face of Granada's larger neighbours, the Christian kingdom of Castile and the Muslim Marinid state of Morocco, as well as an internal rebellion by his family's former allies, the Banu Ashqilula.
  
  After he took the throne, he negotiated a treaty with Alfonso X of Castile, in which Castile agreed to end support for the Banu Ashqilula in exchange for payments. When Castile took the money but maintained its support for the Banu Ashqilula, Muhammad turned towards Abu Yusuf of the Marinids. The Marinids sent a successful expedition against Castile, but relations soured when the Marinids treated the Banu Ashqilula as Muhammad's equals. In 1279, through diplomatic manoeuvring, Muhammad regained Málaga, formerly the centre of Banu Ashqilula power. In 1280, his diplomacy backfired when Granada faced simultaneous attacks from Castile, the Marinids and the Banu Ashqilula. Attacked by his more powerful neighbours, Muhammad exploited the rift between Alfonso and his son Sancho, as well as receiving help from Volunteers of the Faith, soldiers recruited from North Africa. The threat subsided when Alfonso died in 1284 and Abu Yusuf in 1286; their successors (Sancho and Abu Yaqub, respectively) were preoccupied with domestic matters. In 1288 the Banu Ashqilula emigrated to North Africa at Abu Yaqub's invitation, removing Muhammad's biggest domestic concern. In 1292, Granada helped Castile take Tarifa from the Marinids on the understanding that the town would be traded to Granada, but Sancho reneged on the promise. Muhammad II then switched to the Marinid side, but a Granadan–Marinid attempt to retake Tarifa in 1294 failed. In 1295, Sancho died and was succeeded by Ferdinand IV, a minor. Granada took advantage by conducting a successful campaign against Castile, taking Quesada and Alcaudete. Muhammad also planned a joint offensive with Aragon against Castile, but he died in 1302 before the operation took place. (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...)

  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.

After the introduction of poison gas in World War I, countermeasures were developed. 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.

Machu Picchu is now a popular tourist destination and UNESCO World Heritage Site, and restoration efforts are ongoing.

  Arg-e Bam

  Photograph credit: Diego Delso

  The Arg-e Bam, in Kerman Province in southeastern Iran, is the largest adobe building in the world and a UNESCO World Heritage Site. The ancient citadel has a history dating back around two thousand years, to the Parthian Empire (248 BC – 224 AD), but most of its buildings were constructed during the Safavid dynasty. A strong earthquake on 26 December 2003 largely devastated the fortress and the nearby modern city of Bam. The Arg-e Bam, including the governor's residence, the main tower, the Four Seasons Palace and the hammam, were nearly totally destroyed; this photograph from 2016 shows the citadel partially reconstructed.

  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.

  Vegetable Lamb of Tartary

  Artist: Unknown, after Johann Zahn

  A drawing of the Vegetable Lamb of Tartary (Agnus scythicus), a zoophyte of Central Asia. Botanist Henry Lee described it as both a true animal and a living plant, although he did allow for the possibility that the lamb was the fruit of the plant. The lamb was believed to have blood, bones, and flesh like that of a normal lamb. It was connected to the earth by a stem similar to an umbilical cord that propped the lamb up above ground. The cord could flex downward allowing the lamb to feed on the grass and plants surrounding it. Once the plants within reach were eaten, the lamb died, at which point its cotton-like wool would be harvested and used to make textiles.

Nikita Zotov, rotogravure by Alexandr Osipov, 1882–1883

Count Nikita Moiseevich Zotov (Russian: Никита Моисеевич Зотов, romanized: Nikita Moiseyevich Zotov, IPA: [nʲ'kʲta moɨ'sʲɛɪvʲɪt͡ɕ 'zotv] ^ⓘ) (1644 – December 1717) was a childhood tutor and lifelong friend of Russian Tsar Peter the Great. Historians disagree on the quality of Zotov's tutoring. Robert K. Massie, for example, praises his efforts, but Lindsey Hughes criticizes the education that he gave to the future tsar.

Not much is known about Zotov's life aside from his connection to Peter. Zotov left Moscow for a diplomatic mission to Crimea in 1680 and returned to Moscow before 1683. He became part of the "Jolly Company", a group of several dozen of Peter's friends that eventually became The All-Joking, All-Drunken Synod of Fools and Jesters. Zotov was mockingly appointed "Prince-Pope" of the Synod, and regularly led them in games and celebrations. He accompanied Peter on many important occasions, such as the Azov campaigns and the torture of the Streltsy after their uprising. Zotov held a number of state posts, including from 1701 a leading position in the Tsar's personal secretariat. Three years before his death, Zotov married a woman 50 years his junior. He died in December 1717 of unknown causes. (Full article...)
