Ivan IV Vasiljevich the Terrible was Grand Prince (since 1533), the first Russian Tsar (since 1547), the son of Vasili III. He conquered Kazan Khan (1552) and Astrakhan Khan (1556). He introduced the oprichnina in 1565 - a hand-picked group of terrorists who raped and killed anyone Iran did not like. His home policy was accompanied with dreadful repressions and stong enslaving of peasants. Beyond Russia, he took part in the Livonian War (1558-1583) and established commercial connections with England. Crucially, he joined Siberia to the Russian State.
