The Khmelnytsky Uprising against the Polish–Lithuanian Commonwealth left the Cossack Hetmanate in need of powerful military backing. Hetman Bohdan Khmelnytsky initiated negotiations with the Tsardom of Russia to secure protection, offering allegiance to Tsar Alexis in exchange for military support against Poland.
In January 1654 in Pereiaslav, Zaporozhian Cossack leadership formally swore allegiance to Russian Tsar Alexis before a Moscow delegation headed by Vasiliy Buturlin. The resulting agreement, concluded as the March Articles in Moscow, granted the Hetmanate autonomous status within the Russian state while acknowledging the tsar's sovereignty.
The agreement precipitated the Russo-Polish War of 1654–1667. The definitive settlement came with the Treaty of Perpetual Peace in 1686, under which Russia confirmed sovereignty over Zaporozhian Sich, left-bank Ukraine, and Kiev. The precise legal nature of the relationship between Russia and the Hetmanate remains a subject of ongoing scholarly debate.
Political Outcome
The Cossack Hetmanate accepted Russian suzerainty and autonomous status within the Tsardom; the March Articles formalized the arrangement and triggered the Russo-Polish War of 1654–1667.
