False Dmitry II
During the Time of Troubles of the early 17th century, Rostov and Yaroslavl provinces were raided by the rebel forces of False Dmitry II and his Polish–Lithuanian allies. In 1609–1610 the invaders were driven out by a Russian militia of Gagarin and Vysheslavtsev, who gathered their forces in Vologda. In late 1614, the northern part of the region (Poshekhonye) was terrorized by a rogue cossack unit led by ataman Baloven. The next year surrounding areas of Uglich and Romanov were reached by the notorious Polish–Lithuanian Lisowczycy raiders. In 1618 Zaporozhian Cossacks of hetman Sahaidachny captured Yaroslavl, Pereslavl and Romanov, as allies with a Polish invasion of Russia.
