Cossacks in Ukraine

The Cossacks are a nomadic horse riding warrior people who traditionally live by a mix of shepherding, banditry, and selling their services as mercenaries. The term Cossack was applied by Europeans as like kind of a broad term to encompass all the different groups of these people. Back in the 1600s, there was a mass uprising of Ukrainian Cossacks and peasants against the Poles that succeeded in kicking Poland out of Ukraine and also bringing Russia into Russian control. There was also a genocide that occurred during this that the Cossacks committed against Jewish people called the Klemnitsky massacre.
