I want to know the answer to the following question:
Who joined the Cossacks in 1648?
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?
Answer: yes
