Registered Cossacks became a military formation of the Commonwealth army beginning in 1572<ref name="registered">{{in lang|uk}} [http://history.franko.lviv.ua/IIIr_1.htm Registered Cassacks at the Handbook of the History of Ukraine]</ref> soon after the [[Union of Lublin]] (1569), when most of the territory of modern [[Ukraine]] passed to the [[Crown of Poland]]. Registered Cossack formations were based on the [[Zaporozhian Cossacks]] who already lived on the lower reaches of the [[Dnieper River]] amidst the [[Pontic steppes]] as well as on self-defense formations within settlements in the region of modern [[Central Ukraine|Central]] and [[Southern Ukraine]].
