Ivan IV Vasilyevich (Russian: Ivan Vasil'evich, tr. Ivan Vasilyevich; 25 August 1530 - 28 March [O.S. 18 March] 1584), commonly known as Ivan the Terrible or Ivan the Fearsome (Russian:  Ivan Groznyi  , Ivan Grozny; a better translation into modern English

Ivan was the first son of Vasili III and his second wife, Elena Glinskaya, who was of half Serbian and half Lipka Tatar descent, the Glinski clan (nobles based in the Grand Duchy of Lithuania) claiming descent from the Mongol ruler Mamai (1335-1380.) When Ivan was three years old, his father died from an abscess and inflammation on his leg that developed into blood poisoning. Ivan was proclaimed the Grand Prince of Moscow at the request of his father. His mother Elena Glinskaya initially acted as regent, but she died of what many believe to be assassination by poison, in 1538 when Ivan was only eight years old. The regency then alternated between several feuding boyar families fighting for control. According to his own letters, Ivan, along with his younger brother Yuri, often felt neglected and offended by the mighty boyars from the Shuisky and Belsky families. In a letter to Prince Kurbski Ivan remembers, "My brother Iurii, of blessed memory, and me they brought up like vagrants and children of the poorest. What have I suffered for want of garments and food!!" It should be noted, however, that the historian Edward L Keenan has presented compelling reasons to doubt the authenticity of the source in which these quotes are found.  On 16 January 1547, at age sixteen, Ivan was crowned with Monomakh's Cap at the Cathedral of the Dormition. He was the first to be crowned as "Tsar of All the Russias", hence claiming the ancestry of Kievan Rus'. Prior to that, rulers of Muscovy were crowned as Grand Princes, although Ivan III the Great, his grandfather, styled himself "tsar" in his correspondence. Two weeks after his coronation, Ivan married his first wife Anastasia Romanovna, a member of the Romanov family, who became the first Russian tsaritsa.  By being crowned Tsar, Ivan was sending a message to the world and to Russia: he was now the only supreme ruler of the country, and his will was not to be questioned. "The new title symbolized an assumption of powers equivalent and parallel to those held by former Byzantine Emperor and the Tatar Khan, both known in Russian sources as Tsar. The political effect was to elevate Ivan's position." The new title not only secured the throne, but it also granted Ivan a new dimension of power, one intimately tied to religion. He was now a "divine" leader appointed to enact God's will, as "church texts described Old Testament kings as 'Tsars' and Christ as the Heavenly Tsar." The newly appointed title was then passed on from generation to generation: "succeeding Muscovite rulers ... benefited from the divine nature of the power of the Russian monarch ... crystallized during Ivan's reign."  Despite calamities triggered by the Great Fire of 1547, the early part of Ivan's reign was one of peaceful reforms and modernization. Ivan revised the law code, creating the Sudebnik of 1550, founded a standing army (the streltsy), established the Zemsky Sobor (the first Russian parliament of the feudal Estates type) and the council of the nobles (known as the Chosen Council), and confirmed the position of the Church with the Council of the Hundred Chapters (Stoglavy Synod), which unified the rituals and ecclesiastical regulations of the whole country. He introduced local self-government to rural regions, mainly in the northeast of Russia, populated by the state peasantry.  By Ivan's order in 1553 the Moscow Print Yard was established and the first printing press was introduced to Russia. Several religious books in Russian were printed during the 1550s and 1560s. The new technology provoked discontent among traditional scribes, leading to the Print Yard being burned in an arson attack. The first Russian printers, Ivan Fedorov and Pyotr Mstislavets, were forced to flee from Moscow to the Grand Duchy of Lithuania. Nevertheless, printing of books resumed from 1568 onwards, with Andronik Timofeevich Nevezha and his son Ivan now heading the Print Yard.  Ivan had St. Basil's Cathedral constructed in Moscow to commemorate the seizure of Kazan. There is a false legend that he was so impressed with the structure that he had the architect, Postnik Yakovlev, blinded so that he could never design anything as beautiful again. In reality, Postnik Yakovlev went on to design more churches for Ivan and the walls of the Kazan Kremlin in the early 1560s, as well as the chapel over St. Basil's grave that was added to St. Basil's Cathedral in 1588, several years after Ivan's death. Although more than one architect was associated with this name and constructions, it is believed that the principal architect is one and the same person.  Other events of this period include the introduction of the first laws restricting the mobility of the peasants, which would eventually lead to serfdom, instituted during the rule of future tsar Boris Godunov in 1597. (See also Serfdom in Russia.)  The 1560s brought hardships to Russia that led to dramatic change of Ivan's policies. Russia was devastated by a combination of drought and famine, unsuccessful wars against the Polish-Lithuanian Commonwealth, Tatar invasions and the sea-trading blockade carried out by the Swedes, Poles and the Hanseatic League. His first wife, Anastasia Romanovna, died in 1560, and her death was suspected to be a poisoning. This personal tragedy deeply hurt Ivan and is thought to have affected his personality, if not his mental health. At the same time, one of Ivan's advisors, Prince Andrei Kurbsky, defected to the Lithuanians, took command of the Lithuanian troops and devastated the Russian region of Velikiye Luki. The series of treasons made Ivan paranoically suspicious of nobility.  On 3 December 1564, Ivan departed Moscow for Aleksandrova Sloboda. From there he sent two letters in which he announced his abdication because of the alleged embezzlement and treason of the aristocracy and clergy. The boyar court was unable to rule in Ivan's absence and feared the wrath of the Muscovite citizenry. A boyar envoy departed for Aleksandrova Sloboda to beg Ivan to return to the throne. Ivan agreed to return on condition of being granted absolute power (see Absolute monarchy). He demanded that he should be able to execute and confiscate the estates of traitors without interference from the boyar council or church. Upon this, Ivan decreed the creation of the oprichnina.  The oprichnina consisted of a separate territory within the borders of Russia, mostly in the territory of the former Novgorod Republic in the north. Ivan held exclusive power over the oprichnina territory. The Boyar Council ruled the zemshchina ('land'), the second division of the state. Ivan also recruited a personal guard known as the Oprichniki. Originally it was a thousand strong. The oprichniki were headed by Malyuta Skuratov. One known oprichnik was the German adventurer Heinrich von Staden. The oprichniki enjoyed social and economic privileges under the oprichnina. They owed their allegiance and status to Ivan, not to heredity or local bonds.  The first wave of persecutions targeted primarily the princely clans of Russia, notably the influential families of Suzdal. Ivan executed, exiled or forcibly tonsured prominent members of the boyar clans on questionable accusations of conspiracy. Among those executed were the Metropolitan Philip and the prominent warlord Alexander Gorbaty-Shuisky. In 1566 Ivan extended the oprichnina to eight central districts. Of the 12,000 nobles there, 570 became oprichniks, the rest were expelled.  Under the new political system, the Oprichniki were given large estates, but unlike the previous landlords, could not be held accountable for their actions. These men "took virtually all the peasants possessed, forcing them to pay 'in one year as much as [they] used to pay in ten.'" This degree of oppression resulted in increasing cases of peasants fleeing, which in turn led to a drop in the overall production. The price of grain increased by a factor of ten.
