Background and detail
Military Context. The treaty followed the Ottoman invasion of Polish Ukraine in August 1672. Ottoman forces, led by Grand Vizier Köprülü Fazıl Ahmed and Sultan Mehmed IV, captured the fortress of Kamieniec Podolski and besieged Lwów, forcing the Commonwealth into negotiations.
Treaty Terms. The agreement ceded the Right-bank Bracław Voivodeship, Podole Voivodeship, and part of Kiev Voivodeship to the Ottomans. The Commonwealth also agreed to pay an annual tribute of 22,000 ducats, a condition viewed by many as reducing the state to vassal status.
Political Aftermath. The Polish Sejm refused to ratify the treaty due to the territorial losses and humiliating tribute. Instead, they raised taxes to fund a new army of approximately 37,000 men, leading to the resumption of hostilities in the spring of 1673.
