Answer 2

Genocide,” a term used to describe violence against members of a national, ethnical, racial or religious group with the intent to destroy the entire group, came into general usage only after World War II, when the full extent of the atrocities committed by the Nazi regime against the Jews of Europe during that conflict became known. In 1948, the United Nations declared genocide to be an international crime; the term would later be applied to the horrific acts of violence committed during conflicts in the former Yugoslavia and in the African country of Rwanda in the 1990s. An international treaty signed by some 120 countries in 1998 established the International Criminal Court (ICC), which has jurisdiction to prosecute crimes of genocide.
