The immediate task of the new dynasty was to restore order. Fortunately for Russia, its major enemies, Poland and Sweden, were engaged in a conflict with each other, which provided Russia the opportunity to make peace with Sweden in 1617. The Polish–Muscovite War (1605–1618) was ended with the Truce of Deulino in 1618, restoring temporarily Polish and Lithuanian rule over some territories, including Smolensk, lost by the Grand Duchy of Lithuania in 1509.

The early Romanovs were weak rulers. Under Mikhail, state affairs were in the hands of the tsar's father, Filaret, who in 1619 became Patriarch of Moscow. Later, Mikhail's son Aleksey (r. 1645-1676) relied on a boyar, Boris Morozov, to run his government. Morozov abused his position by exploiting the populace, and in 1648 Aleksey dismissed him in the wake of the Salt Riot in Moscow.

After an unsuccessful attempt to regain Smolensk from Poland in 1632, Russia made peace with Poland in 1634. Polish king Władysław IV Vasa, whose father and predecessor was Sigismund III Vasa, had been elected by Russian boyars as tsar of Russia during the Time of Troubles, renounced all claims to the title as a condition of the peace treaty.
