The Treaty of Zboriv was signed on 18 August 1649, after the Battle of Zboriv when the Crown forces of about 35,000, 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 50,000.
The Treaty of Zboriv consisted of two separate agreements between Ukraine and the Commonwealth and between Crimea and the Commonwealth.1649 treaty of Zboriv between Crimea and the Commonwealth (ЗБОРІВСЬКИЙ ДОГОВІР МІЖ КРИМСЬКИМ ХАНАТОМ ТА РІЧЧЮ ПОСПОЛИТОЮ 1649).

The following cities will be allowed to accept Cossacks to the Register: on this side of Dnieper: from Dymer, Hornostaipil, Korostyshiv, Pavoloch, Pohrebyshche, Pryluka, Vinnytsia, Bratslav, Yampil to Dniester and on the other side of Dnieper: in Oster, Chernihiv, Nizhyn, Romny up to Muscovy border and also everywhere between Dnieper and Dniester. Everyone who want to be the Cossack may choose so, retaining all his property. The Register must be completed latest on the day of Intercession of the Theotokos. Chyhyryn will be the Host City of Zaporozhian Cossacks forever and now is given to Bohdan Khmelnytsky.

All nobles, both Orthodox and Catholic, who joined Cossacks, it will be forgiven. All infamies will be cancelled. The Crown Forces are not allowed to be based in Cossack towns. Jews are not allowed to be citizens of Cossack towns. In the Kyiv Voivodeship, Bratslav Voivodeship and Chernihiv Voivodeship all offices can be held by Orthodox. In the city of Kiev, because there are privileged Ruthenian schools, the Jesuit fathers are not to be founded there and in other Ukrainian cities, but to be transferred somewhere else. And all other schools, which were there in ancient times, are to be preserved.
