Thus Ivan’s early years were marked by political instability, and possibly personal insecurity too (as Sergei Eisenstein, the famous Soviet film-maker, suggests in his classic but unfinished film treatment of Ivan). It is also said that he grew up wild and violent, but the source was a close friend who became a bitter enemy and cannot be trusted. 5 Nor was it as easy for the young ruler to establish his authority as the chronicle makes out. However, we can infer from his own writings and contemporary accounts that Ivan had received an excellent education for his time and station. He was both highly literate and musical, interested in the outside world, and, as befitted a monarch, both a keen huntsman and dutiful in matters of religion. He received instruction from senior officials concerned with legal administration, military and foreign affairs, and, of course, the Church, so that he was well apprised of Muscovite policies and statecraft and knew something about the lands beyond his frontiers.
Crowned at his own instance in January 1547, the sixteen-year-old tsar was also seized of new ideas. If he did not actually read Machiavelli, evidence suggests that he was acquainted with many of the Italian’s precepts. A German immigrant, Hans Schlitte, fired his interest in German science, and he seized eagerly on information about new technology. The Tsar sent Schlitte back to Germany with commissions to recruit doctors, artisans, and experts in explosives and other Western arts. A Dutchman called Akema and a citizen of Hamburg called Marselius were soon to found a firearms manufactory at Tula, which was to be developed into the centre of Russia’s arms industry. In 1550 Ivan founded a corps of musketeers
Others of Ivan’s immediate concerns were to extend and enforce the law, to root out corruption, and to stamp out the factionalism which had marred his boyhood. Above all, he wanted to enforce obedience. In 1550 a new law book was issued. Besides repeating previous legislation, this co-ordinated the operations of central and local government, laid down rules for due process, and required court decisions to be recorded. Ivan’s first months in power were also marked by the expansion of the ministerial council, which reflected the use of patronage to bolster his authority. However, critical decisions were pondered by a kitchen cabinet of close advisers - the ‘Chosen Council’ — among them a learned monk called Silvestr, who did duty in one of the Kremlin churches; a foreign-policy specialist, Daniil Adashev; and a military specialist from the western provinces, Prince Andrei Kurbskii. It was with this group that in 1551 Ivan decided to mount his first great campaign the following year - against Kazan.
The Khanate of Kazan occupied a strategic location adjoining Muscovy’s southern frontier, and Moscow had interfered in its affairs for decades past. However, the influence exerted was only intermittently effective. Control over Kazan needed to be secured. A phase of political instability there encouraged Ivan and his advisers to launch a major campaign to seize the city. 6 Kazan was defended by walls the height of three grown men and more, and by 30,000 Tatars. But young Ivan brought 150,000 troops to the scene, as well as siege equipment, explosive devices, and a train of 150 guns. A siege began on 23 August 1552.
