Ivan Petrizhitsky-Kulaga

Seen as a supporter of the Polish–Lithuanian Commonwealth, he was stripped of his hetman position in an internal Cossack conflict and executed in 1632.

Shortly after his election in 1631 he handed the Swedish diplomats l'Admiral and Des Greves, who attempted to negotiate with the Cossacks, to the Polish government.

[2] In this petition, the Cossacks requested that they, as warriors and defenders of the state, be given full political equality with the Polish nobility (szlachta).

[3] His unpopular stance as a Polish loyalist and an internal power struggle among the Cossacks triggered a coup d'etat.

Petrizhitsky-Kulaga himself was executed in Kiev later that year by other Cossacks[7] and succeeded as hetman by Andrii Didenko.
