The rise of the Cossacks in the 16th and 17th centuries was central to Ukraine's fight for freedom. Originating as a warrior class, Cossacks formed military communities that resisted Polish domination and sought autonomy. The 1648 Khmelnytsky Uprising, led by Bohdan Khmelnytsky, was a key moment in Ukrainian history, as Cossacks fought for independence and formed a brief alliance with Russia. Despite challenges, the Cossacks symbolized Ukraine’s enduring struggle for sovereignty and identity. #R
