In 1580 the Sejm in Warsaw passed the Order in Ukraine (Porządek ze strony Niżowców i Ukrainy) Act, in which Registered Cossacks were banned from raids to the Zaporizhian Sich, taking captives or pillaging.

The immediate cause of the uprising was a dispute between the Cossack hetman Krzysztof Kosiński and the starosta of Bila Tserkva and Voivode of Volyn, Janusz Ostrogski.

Kosinski, a nobleman from Podlasie,[5][verification needed] received lands in the Rokitno area, abandoned after the Crimean Tartar invasions, from Hetman Jan Zamoyski in 1590.

[1] On 29 December 1591, Kosinski attacked the house of Dmitry Kurtsevich Buliga in Bila Tserkva, stealing valuables and land grant documents.

He established contacts with Russia and Tatars , seeking support against the Commonwealth everywhere .But in May 1593 he was finally defeated at Cherkasy by Alexander Wisniowiecki and died in unclear circumstances.
