Passage: The death of Ivan's childless son Feodor was followed by a period of civil wars and foreign intervention known as the "Time of Troubles" (1606–13). Extremely cold summers (1601–1603) wrecked crops, which led to the Russian famine of 1601–1603 and increased the social disorganization. Boris Godunov's (Борис Годунов) reign ended in chaos, civil war combined with foreign intrusion, devastation of many cities and depopulation of the rural regions.

Moscow revolted but riots there were brutally suppressed and the city was set on fire.The crisis provoked a patriotic national uprising against the invasion, both in 1611 and 1612. Finally, a volunteer army, led by the merchant Kuzma Minin and prince Dmitry Pozharsky, expelled the foreign forces from the capital on 4 November [O.S. 22 October] 1612.The Russian statehood survived the "Time of Troubles" and the rule of weak or corrupt Tsars because of the strength of the government's central bureaucracy. Government functionaries continued to serve, regardless of the ruler's legitimacy or the faction controlling the throne. However, the "Time of Troubles" provoked by the dynastic crisis resulted in the loss of much territory to the Polish–Lithuanian Commonwealth in the Russo-Polish war, as...
