Influential relatives of the Ruthenian and Lithuanian "szlachta" in Moscow helped to create the Russian–Polish alliance against Khmelnitsky's Cossacks, portrayed as rebels against order and against the private property of the Ruthenian Orthodox "szlachta". Don Cossacks' raids on Crimea leaved Khmelnitsky without the aid of his usual Tatar allies. From the Russian perspective, the rebellion ended with the 1654 Treaty of Pereyaslav, in which, in order to overcome the Russian–Polish alliance against them, the Khmelnitsky Cossacks pledged their loyalty to the Russian Tsar. In return, the Tsar guaranteed them his protection; recognized the Cossack "starshyna" (nobility), their property, and their autonomy under his rule; and freed the Cossacks from the Polish sphere of influence and the land claims of the Ruthenian "szlachta".
