False Dmitry
The False Dmitrys were impostors who emerged during Russia's Time of Troubles (1598–1613), a period of dynastic extinction, famine, civil strife, and foreign incursions following the death of Tsar Feodor I, claiming to be Tsarevich Dmitry Ivanovich, the youngest son of Ivan IV ("the Terrible"), whose death in Uglich in 1591 had been officially ruled a suicide but widely suspected as murder amid power struggles.[1]False Dmitry I, the most prominent, surfaced in Polish-Lithuanian territories around 1603–1604, securing backing from Catholic Polish magnates seeking influence over Muscovy and from Russian exiles opposed to Tsar Boris Godunov; he exploited Godunov's regime's unpopularity, including famine and rumored involvement in Dmitry's death, to lead an invasion that entered Moscow after Godunov's sudden demise in April 1605, enabling his coronation as tsar on 20 June 1605.[1][2]
His eleven-month reign featured reforms like reducing the service tenure for peasants to limit boyar power, tolerance toward Catholicism that alienated Orthodox clergy, and marriage to Polish noblewoman Marina Mniszech, but ended in a boyar-led coup on 17 May 1606, where he was killed and his body desecrated amid accusations of Polish sympathies and heresy.[1][2]
Contemporary Russian sources, including post-mortem investigations by the new regime of Vasily Shuisky, identified him as Grigory Otrepyev (or Otrepiev), a defrocked monk from the Chudov Monastery accused of sorcery and fleeing to Poland, though this rests on adversarial testimony without independent corroboration, fueling ongoing scholarly debate over whether he was a deliberate fraud or possibly the genuine survivor exploiting popular belief in his escape.[3][1]
False Dmitry II ("the Thief of Tushino"), appearing in 1607 with Cossack and peasant support, maintained a rival court but was killed in December 1610; a third, minor pretender in 1611–1612, briefly held Pskov before execution, their collective risings reflecting deep-seated monarchist expectations and social grievances that prolonged the Troubles until the Romanov dynasty's establishment in 1613.[1][2]
