How a runaway monk became the most successful imposter in Russian history

History · Published 3 October 2026 Swipe more like this →

In short: During Russia's chaotic Time of Troubles, a man claiming to be the long-dead son of Ivan the Terrible seized the throne. Supported by Polish nobles and an army of adventurers, he ruled for nearly a year, proving that in a fractured state, a convincing story can be more powerful than bloodline.

The first False Dmitry, widely identified by historians as the former monk Grigory Otrepyev, emerged during the Time of Troubles (1598–1613). Following the death of Fyodor I, the last tsar of the Rurik dynasty, the Russian throne was claimed by Boris Godunov. Dmitry, who had lived in Moscow as a member of the gentry before entering monastic life, fled to Lithuania in 1603. There, he successfully solicited support from Polish and Lithuanian nobles, as well as the Jesuits, by claiming to be the legitimate heir to the throne—the son of Ivan the Terrible who had died in 1591.

Dmitry’s invasion of Russia in 1604 initially faced military setbacks, but the political landscape shifted dramatically when Tsar Boris died suddenly in April 1605. With the government army defecting to his side, Dmitry entered Moscow in June 1605 and was proclaimed tsar. His reign was short-lived, lasting only until May 1606. He alienated the Russian boyars by ignoring traditional court customs, favoring his Polish entourage, and marrying Marina Mniszek, the daughter of a Polish nobleman. His reign ended violently when Vasily Shuysky led a coup d’état and assassinated him.

The phenomenon of the False Dmitry did not end with the first pretender’s death. Rumors of his survival persisted, leading to the rise of a second pretender, known as the 'Thief of Tushino,' who established a rival government in 1608. Even after his death in 1610, a third pretender, a deacon named Sidorka, appeared in 1611. These imposters exploited the deep instability of the era, drawing support from Cossacks and rebels who were disillusioned with the ruling boyars. While the first False Dmitry remains the most famous, the repeated emergence of these figures highlights the fragility of legitimacy during one of Russia’s most turbulent periods.
