Fyodor (Theodore) I Ivanovich (31 May 1557 16/17 January (NS) 1598) was the last Rurikid Tsar of Russia (15841598), son of Ivan IV (The Terrible) and Anastasia Romanovna. He was born in Moscow and crowned Tsar and Autocrat of all Russia at Assumption Cathedral, Moscow, on 31 May 1584.
Being unhealthy and, by some reports, intellectually disabled, Feodor was only the nominal ruler, having his duties handed over to his wife's brother and trusted minister Boris Godunov, who would later succeed Feodor as tsar. Feodor's childless death left the Rurikid dynasty extinct, and spurred Russia's descent to the catastrophic Time of Troubles.
