Left-bank Ukraine
In 1687 Ivan Mazepa accused Samoylovych of conspiring to secede from Russia, secured his ouster, and was elected the Hetman of Left-bank Ukraine in Kolomak, with the support of Vasily Galitzine. At the same time Ivan Mazepa signed the Kolomak Articles, which were based on the Hlukhiv Articles of Demian Mnohohrishny.
