Q: Question: When was the city where False Dmitry I was murdered established? Passage:The Tsardom of Russia had been experiencing the Time of Troubles (1598–1613) since the death of Tsar Feodor I in 1598, causing widespread political instability and a violent succession crisis for the title of Tsar of Russia by usurpers known as the False Dmitris. In 1605, the Polish-Muscovite War started when the Polish-Lithuanian Commonwealth unofficially invaded Russia in support of False Dmitry I against the unpopular crowned tsar Boris Godunov, seeking to exploit the country's weakness for their own gain. Godunov died in June 1605 and was replaced by False Dmitry I, whose popularity among the Russian populace declined rapidly during his reign, and the Polish withdrew when he was eventually murdered during an uprising in Moscow in May 1606.
