ethnic cleansing

Etymology
Possibly a, though this is probably attested later. Popularized by (and still often associated with) the wars in former Yugoslavia during the 1990s; however, versions of the phrase have been attested since the 1860s in various languages (with the earliest attestation translating directly to the phrase being 🇨🇬 from 1941) and it probably arose independently on numerous occasions.

Noun

 * 1)  The mass expulsion or killing of people belonging to one ethnic group by those of another.
