False Dmitry in the context of "House of Romanov"

The Time of Troubles (Russian: Смутное время, romanized: Smutnoye vremya), also known as Smuta (Russian: Смута, lit. 'troubles'), was a period of political crisis in Russia which began in 1598 with the death of Feodor I, the last of the House of Rurik, and ended in 1613 with the accession of Michael I of the House of Romanov at the 1613 Zemsky Sobor.

It was a period of deep social crisis and lawlessness following the death of Feodor I, a weak and possibly intellectually disabled ruler who died without an heir. His death ended the Rurik dynasty, leading to a violent succession crisis with numerous usurpers and false Dmitrys (impostors) claiming the title of tsar. Russia experienced the famine of 1601–1603, which killed almost a third of the population, within three years of Feodor's death. Russia was also occupied by the Polish–Lithuanian Commonwealth during the Polish–Russian War and lost Smolensk.

The Polish–Russian War was a conflict fought between the Polish–Lithuanian Commonwealth and the Tsardom of Russia from 1609 to 1618.

Russia had been experiencing the Time of Troubles since the death of Tsar Feodor I in 1598, which caused political instability and a violent succession crisis upon the extinction of the Rurik dynasty; furthermore, a major famine ravaged the country from 1601 to 1603. Poland exploited Russia's civil wars when powerful members of the Polish szlachta began influencing Russian boyars and supporting successive pretenders to the title of tsar of Russia against the crowned tsars Boris Godunov (r. 1598–1605) and Vasili IV Shuysky (r. 1606–1610). From 1605, Polish nobles conducted a series of skirmishes until the death of False Dmitry I in 1606, and they invaded again in 1607 until Russia formed a military alliance with Sweden two years later. The King of Poland, Sigismund III Vasa, declared war on Russia in response in 1609, aiming to gain territorial concessions and to weaken Sweden's ally. Polish forces won many early victories such as the 1610 Battle of Klushino. In 1610, Polish units entered Moscow and Sweden withdrew from the military alliance with Russia, instead triggering the Ingrian War of 1610-1617 between Sweden and Russia.
