Ivan III Vasilyevich (Russian: Иван III Васильевич; 22 January 1440 – 27 October 1505), also known as Ivan the Great, was a Grand Prince of Moscow and Grand Prince of all Rus'. Ivan served as the co-ruler and regent for his blind father Vasily II from the mid-1450s before he officially ascended the throne in 1462.

He multiplied the territory of his state through war and through the seizure of lands from his dynastic relatives, ended the dominance of the Tatars over Russia, renovated the Moscow Kremlin, introduced a new legal codex and laid the foundations of the Russian state. His 1480 victory over the Great Horde is cited as the restoration of Russian independence 240 years after the fall of Kiev to Mongols' invasion.Ivan was the first Russian ruler to style himself "tsar", albeit not as an official title. Through marriage to Sofia Paleologue, he made the double-headed eagle Russia's coat of arms and adopted the idea of Moscow as Third Rome. His 43-year reign was the second longest in Russian history, after that of his grandson Ivan IV.
