Bohdan Khmelnytsky (1595–1657)
Born 1595 CE, died 1657 CE.
Zynoviy Bohdan Mykhailovych Khmelnytsky of the Abdank coat of arms (c. 1595 – 6 August 1657) was a Ruthenian nobleman and military commander of Zaporozhian Cossacks as Hetman of the Zaporozhian Host, which was then under the suzerainty of the Polish–Lithuanian Commonwealth. He led the Cossacks to victory in a successful uprising against the Commonwealth and its magnates (1648–1654) that resulted in the creation of an independent Cossack state in Dnieper Ukraine. In 1648–1649, the Cossacks under Khmelnytskyi's leadership massacred tens of thousands of Poles and Jews, with more handed over as yasir (slaves) to his Crimean Tatar allies, one of the most traumatic events in Polish and Jewish history. Under his rule of the newly established Cossack state, the massacres continued until at least 1652 and possibly led to hundreds of thousands of deaths, with the goal of eradicating non-Orthodox Ruthenian populations.
