Genocide was first recognised as a crime under international law in 1946 by the United Nations General Assembly (A/RES/96-I). It was codified as an independent crime in the 1948 Convention on the Prevention and Punishment of the Crime of Genocide (the Genocide Convention). The Convention has been ratified by 149 States (as of January 2018).
In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:
Killing members of the group;
Causing serious bodily or mental harm to members of the group;
Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
Imposing measures intended to prevent births within the group;
Forcibly transferring children of the group to another group.
