Ivan III (1440-1505), called Ivan the Great, was grand duke of Moscow from 1462 to 1505. During his reign, the Russian state gained independence from the Mongol Tatars, finally ending 200 years of their rule. He completed the unification of Russian land. Ivan also made Moscow the centre of the Russian world by considerably expanding its borders. He was one of the longest-reigning Russian rulers in history.
