AP World History: Modern
Ethnic cleansing refers to the systematic removal or extermination of a particular ethnic or religious group from a specific territory, often through violence, intimidation, and forced displacement. This practice is characterized by acts of violence, including genocide, and is often justified by the perpetrators as a means to achieve a 'homogenous' society. The term became widely recognized in the context of mass atrocities and human rights violations during the 20th century, particularly after the events of World War II.
