Peace of BiaƂa Cerkiew

Poland [1651]

Quick Summary

The Peace of BiaƂa Cerkiew was a treaty signed on September 28, 1651, between Poland and the rebel Cossacks led by Bohdan Khmelnytsky. This agreement followed the Polish victory at the Battle of Beresteczko, where King John Casimir defeated Khmelnytsky's forces.12

The treaty significantly reduced the autonomy granted to the Cossacks by the earlier Compact of ZborĂłw. It lowered the number of "registered" Cossacks (a privileged class) from 40,000 to 20,000 and restricted their territorial control. Neither the Cossacks nor the Polish parliament fully accepted the terms, leading to continued conflict and the Cossacks' eventual decision to seek suzerainty from the Russian tsar in 1654.12
