The Treaty of Zboriv was signed on August 18, 1649,[1] after the Battle of Zboriv when the Crown forces of about 25,000, led by King John II Casimir of Poland, clashed against a combined force of Cossacks and Crimean Tatars, led by Hetman Bohdan Khmelnytsky and Khan İslâm III Giray of Crimea respectively, which numbered about 80,000.
The Treaty of Zboriv consisted of two separate agreements between Ukraine and the Commonwealth and between Crimea and the Commonwealth.[2]
The Treaty of Zboriv plays an important role in history of Ukraine as it turned the Polish-Lithuanian Commonwealth former mutineers into citizens of a new political community.[3] [4]
According to the concluded agreement, the number of Registered Cossacks increased to 40,000; the Polish army, Uniates, and Jews were banned from the territory of the Kyiv Voivodeship, Bratslav Voivodeship, and Chernihiv Voivodeship; governmental offices in the Cossack Hetmanate could be held only by Eastern Orthodox nobility (either Polish or Ukrainian administration of Eastern Orthodox religion), the Orthodox Church was granted privileges[5] and the Crimean Khanate was to be paid a large sum of money.[6]
The treaty was ratified by the Diet, which was in session between November 1649 and January 1650, but hostilities resumed when Catholic bishops refused to recognise the provisions of the treaty (admission to the Senate of the Orthodox metropolitan of Kyiv, Sylvestr Kosiv).[7]
