The Dnieper Cossacks of Ukraine formed the Zaporozhian Sich centered around the fortified Dnieper islands. Initially a vassal of Poland-Lithuania, the increasing social and religious pressure from the Commonwealth in the mid 17th century, forced them to proclaim an independent Cossack Hetmanate, which began a massive rebellion under Hetman Bohdan Khmelnytsky. Afterwards, the Treaty of Pereyaslav with Russia, secured Ukraine within the growing state. Wikipedia
