I want to know the answer to the following question:
Why dd the Peasants of Ukraine join the Cossacks?
All the background I'm provided with is that "In 1648, the peasants of Ukraine joined the Zaporozhian Cossacks in rebellion against Poland-Lithuania during the Khmelnytsky Uprising, because of the social and religious oppression they suffered under Polish rule.". Is that enough to answer the question?
