Pereiaslav Treaty of 1630

Pereiaslav Treaty of 1630 (Переяславська угода 1630 р.; Pereiaslavska uhoda 1630 r.). An agreement between the Cossacks and Poland, signed on 8 June 1630 by the Polish hetman Stanisław Koniecpolski after a successful Cossack and peasant uprising led by Taras Fedorovych routed the Polish army at Pereiaslav on 25 May. The treaty amended the Treaty of Kurukove of 1625 by increasing the allowable number of registered Cossacks from 6,000 to 8,000. The additional 2,000 were to be chosen by a commission made up of existing registered Cossacks and participants in the uprising, and the Cossacks were granted the right to elect their own hetman. Nonregistered Cossacks were granted amnesty but had to return to their homes on the nobles’ estates. The Cossacks refused the Poles’ request to hand over Fedorovych and elected T. Orendarenko as their hetman. The treaty was no more than a temporary compromise, for soon new Cossack-Polish conflicts erupted that resulted in the revolts led by Pavlo Pavliuk in 1637 and Yakiv Ostrianyn in 1638. Fedorovych’s uprising and the treaty are described in a study by Mykhailo Antonovych (1944).
