Ivan

Ivan is the East and South Slavic form of John, itself derived from the Hebrew name Yohanan, meaning God is gracious. It has been one of the most common masculine names throughout Russian and broader Slavic history, borne by several tsars of Russia, most notably Ivan III, who consolidated the Russian state, and the fearsome Ivan IV, known as Ivan the Terrible. The name spread beyond Slavic languages into Italian, Portuguese, Romanian, and Scandinavian use, reflecting the wide cultural reach of its bearers. Related forms include Iván in Spanish and Hungarian, as well as Johannes, Giovanni, Juan, and Jan across other European traditions.
