of a city. On 22 May 1589, King Sigismund III granted the city of Iskorosten its first charter. In 1649, during the Khmelnytsky Uprising, a detachment of Cossacks led by Geraski laid siege to the city. After a bloody battle, the Cossacks captured Iskorosten from the Polish defenders, and the city's fortifications were completely destroyed during the assault. In 1654, Hetman Bohdan Khmelnytsky, as a result of the Pereyaslav Rada, signed an agreement with Tsar Alexei Mikhailovich on the transition of Ukraine to Russian jurisdiction. However, from 1667 to 1795, the lands surrounding Iskorosten continued to be part of the Polish–Lithuanian Commonwealth. In 1768, during the Zaporozhian Cossack and Uman Cossack uprising (led by Maksym Zalizniak and Ivan Gonta respectfully), Ukrainian cossack leader or haidamak Ivan Bondarenko of Kriukivshchyna intended to storm Korosten and incorporate it into his territory. However, the uprising was crushed, and his intentions were never realized.
