False Dmitriy I, pretender to the Russian throne (b. 1582)

False Dmitry I (Russian: Лжедмитрий I, tr. Lzhedmitriy I) (or Pseudo-Demetrius I) reigned as the Tsar of Russia from 10 June 1605 until his death on 17 May 1606 under the name of Dmitriy Ivanovich (Russian: Дмитрий Иванович). According to historian Chester S.L. Dunning, Dmitry was "the only Tsar ever raised to the throne by means of a military campaign and popular uprisings".He was the first, and most successful, of three "pretenders" (Russian: самозванцы (sing.: самозванец), romanized: samozvanets) who claimed during the Time of Troubles to be the youngest son of Ivan the Terrible, tsarevich Dmitry Ivanovich, who supposedly escaped a 1591 assassination attempt when he was eight years old. It is generally believed that the real Dmitry of Uglich died in Uglich in 1591. False Dmitry claimed that his mother, Maria Nagaya, anticipated the assassination attempt ordered by Boris Godunov and helped him escape to a monastery in the Russian Empire, and the assassins killed somebody else instead. He said he fled to the Polish–Lithuanian Commonwealth after he came to the attention of Boris Godunov, who ordered him seized. Many Polish nobles did not believe his story, but nonetheless supported him.With the support of the Polish–Lithuanian Commonwealth, False Dmitry invaded the Russian Empire in 1605, but the war ended with the sudden death of Boris Godunov. Disaffected Russian boyars staged a coup against the new tsar, Feodor II. False Dmitry entered Moscow on 21 July 1605, and was crowned tsar. Maria Nagaya accepted him as her son and "confirmed" his story. False Dmitry's reign was marked by his openness to Catholicism and allowing foreigners into Russia. This made him unpopular with the boyars, who staged a successful coup and killed him eleven months after he took the throne. His wife of 10 days, Marina, would later "accept" False Dmitry II as her fallen husband.
