Anastasia Romanovna Zakharyina-Yurieva (1530 – 7 August 1560) was the first spouse of the Russian Tsar Ivan the Terrible and the first Russian Tsaritsa. She was the mother of Feodor I, the last lineal Rurikid Tsar of Russia and the great-aunt of Michael I of Russia, the first Tsar of the Romanov dynasty. Early life and ancestry Anastasia was the second daughter of the boyar Roman Yurievich Zakharyin-Yuriev, who served as Okolnichy during the reign of Grand Prince Vasily III. The house of Zakharyin-Yuriev was a minor branch of a noble family that had already been at court, so it's possible that Ivan met Anastasia before the bride show, though no records of that exist.

Anastasia and Ivan's marriage took place on 3 February 1547, at the Cathedral of the Annunciation. She gave birth to a total of six children: Anna, Maria, Dmitry, Ivan, Eudoxia, and Feodor. It is widely believed that Anastasia had a moderating influence on Ivan's volatile character. Sir Jerome Horsey, an agent for the Russia Company and envoy for the English court, wrote in his memoirs about Anastasia and Ivan IV: "He being young and riotous, she ruled him with admirable affability and wisdom”. In the summer of 1560, Anastasia fell ill to a lingering illness and died on 7 August. In consequence, Ivan suffered a severe emotional collapse, suspecting that his wife had been a victim of malicious actions and had been poisoned by the boyars. Although he had no evidence of such
