Cherń ( Ukrainian: чернь ) - a term coined in the 17th century to describe peasants who did not have the status of Cossacks and lived in the Dnieper Ukraine , i.e. the Bracław , Kiev and Chernihiv voivodeships of the Polish-Lithuanian Commonwealth . Cherń was also referred to as peasants who took part in Cossack uprisings .
