The Cossack uprisings (also kozak rebellions, revolts) were a series of military conflicts between the Cossacks and the states claiming dominion over the territories they lived in, namely the Polish–Lithuanian Commonwealth and Russian Empire during the 16th, 17th, and 18th centuries. The conflict resulted from both states' attempts to exert control over the independent-minded Cossacks. While the early uprisings were against the Commonwealth, as the Russian Empire gained increasing and then total control over the Ruthenian (Ukrainian) lands where the Cossacks lived, the target of Cossacks uprisings changed as well.
The origins of the first Cossacks are disputed. Traditional historiography dates the emergence of Cossacks to the 14th to 15th centuries. Towards the end of the 15th century, the Ukrainian Cossacks formed the Zaporozhian Sich centered on the fortified Dnipro islands. Initially a vassal of Polish–Lithuanian Commonwealth, the increasing social and religious pressure from the Commonwealth sparked a series of uprisings, and the proclamation of an independent Cossack Hetmanate, culminating in a rebellion under Bohdan Khmelnytsky in the mid-17th century. While the Cossacks were useful to the Polish-Lithuanian states in the war periods, they proved to be more problematic in the peacetime, due to their raids on the Commonwealth neighbours (primarily, the Ottoman Empire and its allies). Further, the Polish nobility tried to assert control over the Cossack territories, turn them into feudal latifundia, limit the growth of the militant Cossacks, and even reverse it, by turning the Cossacks into serfs. Afterward the Khmelnytsky Uprising, the Treaty of Pereyaslav brought most of the Cossack Hetmanate under Russian control.
The Zaporozhian Cossacks were not the only notable group of Cossacks; others included the Don Cossack Host, Dlobodsk Cossacks, Terek Cossacks and Yaik Cossacks. As the Tsardom of Muscovy took over the disputed Cossacks lands from the Poland–Lithuania, eventually all Cossacks came under the Russian rule, but the Tsarist and later Imperial government had only a limited control over the Cossacks. The Cossacks provided refuge for runaway serfs and bandits, and often mounted unauthorized raids and pirate expeditions against the Ottoman Empire. While the Cossack hosts in the Russian Empire served as buffer zones on its borders, the expansionist ambitions of the empire relied on ensuring control over the Cossacks, which caused tension with their traditional independent lifestyle. As the empire attempted to limit Cossacks autonomy in the 17th and 18th centuries, this resulted in rebellions led by Stenka Razin, Kondraty Bulavin and Yemelyan Pugachev. In extreme cases, whole Hosts could be dissolved, as was the fate of the Zaporozhian Sich in 1775. In this last phase of their history, the Cossacks lost most of their autonomy to the Russian state.
Cossack uprisings, like the Cossack people themselves, have been portrayed variously in the Polish, Russian and Ukrainian historiographers.
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, received lands in the Rokitno area, abandoned after the Crimean Tartar invasions, from Hetman Jan Zamoyski in 1590. However, these lands were taken over by Aleksander Wiśniowiecki and later ceded to Janusz Ostrogski. Feeling wronged, Kosinski attacked Bila Tserkva in December 1591, which sparked an uprising. On 29 December 1591, Kosinski attacked the house of Dmitry Kurtsevich Buliga in Bila Tserkva, stealing valuables and land grant documents. He then attacked Bohuslav, Tripoli and Pereyaslav, spreading the conflict to Kievshchyna, Braclawshchyna and Volhynia.[1] King Sigismund III Vasa appointed a commission to put down the rebellion, headed by Mikołaj Jazłowiecki. In 1592, after unsuccessful negotiations, Kosinski continued fighting, destroying Ostrogski's estates. The final battle took place on 2 February 1593 at Piatek, where Kosinski's army was defeated by Janusz Ostrogski. After the surrender, Kosinski fled to Zaporozhye, but in May 1593 he was finally defeated at Cherkasy by Alexander Wisniowiecki and died in unclear circumstances. The 1593 Sejm declared the participants in the uprising to be traitors, but a settlement was later reached that allowed the registered Cossacks to keep their weapons and Chaika, declaring a general amnesty.
