Ethnic cleansing
There is no official legal definition of ethnic cleansing.  However, both the International Criminal Court (ICC) and the International Criminal Tribunal for the Former Yugoslavia (ICTY) define deporting a population from its home as a crime against humanity.  Other crimes that happen during ethnic cleansing are treated as separate crimes that may fit under the definitions of genocide or crimes against humanity.  For example, murdering, raping, and persecuting large groups of people are all crimes against humanity under the International Criminal Court's laws.
