The Battle of Zboriv in 1649 saw Polish Crown forces of approximately 35,000 under King John II Casimir clash with a combined Cossack and Crimean Tatar army of roughly 50,000 led by Hetman Bohdan Khmelnytsky and Khan İslâm III Giray. The military confrontation necessitated a diplomatic resolution between the warring parties.
On August 18, 1649, two separate treaty agreements were concluded at Zboriv: one between the Cossack Hetmanate (Ukraine) and the Polish-Lithuanian Commonwealth, and another between Crimea and the Commonwealth. These agreements followed directly from the military standoff at the Battle of Zboriv and were signed by representatives of all major parties involved.
The Treaty of Zboriv granted the Cossacks formal recognition within the Commonwealth's political framework, converting what had been regarded as mutineers into citizens of a recognized political community. This represented a significant shift in the status of the Cossack Hetmanate and shaped subsequent relations between Ukraine and the Polish-Lithuanian Commonwealth.
