Pavliuk uprising

Pavliuk ordered the captured commanders of the Registered Cossacks to be executed and issued a declaration, in which he proclaimed a fight against the masters.

Most likely it was the social tension between the "Blacks", or poor peasants of the Right-Bank Ukraine, and mighty magnates like Jeremi Wiśniowiecki, who owned considerable wealth and lands in Ruthenia.

[2] He also issued a proclamation to "all Christians" urging them to join his ranks, exploiting all possible sources of dissent in the area, from religious differences, to the defence of "golden liberties", supposedly being violated by the szlachta.

Unable to convince the well-trained and well-equipped Registered Cossacks to join him, Pavliuk also dispatched emissaries to Alexis I, tsar of Muscovy and to İnayet Giray, the khan of Crimea.

[4] Inexperienced Cossacks overextended their wagon fort and their lines were easily pierced by experienced soldiers such as Samuel Łaszcz.

[6] The remaining bands of armed Cossacks were soon defeated and "pushed back into the holes they crawled from", as one contemporary author put it.
