Ivan III
Also called: Ivan the Great, Ivan III Vasilyevich
Grand Prince of Moscow from 1462 to 1505 who gathered the Russian lands, threw off Mongol (Golden Horde) rule in 1480 and styled himself tsar
He served as co-ruler with his blinded father Vasily II before becoming grand prince in 1462. After his first wife died he married the Byzantine princess Sophia through the mediation of the pope. Annexing Novgorod, he carried its assembly bell, symbol of its liberties, off to Moscow, and he also took Tver, greatly expanding his realm. In 1497 he issued Russia’s first unified law code. He is called “Ivan the Great” to distinguish him from his grandson Ivan IV (the Terrible).
