Title:
Genocide

Context:
The word genocide was later included as a descriptive term to the process of indictment, but not yet as a formal legal term According to Lemming, genocide was defined as "a coordinated strategy to destroy a group of people, a process that could be accomplished through total annihilation as well as strategies that eliminate key elements of the group's basic existence, including language, culture, and economic infrastructure.” He created a concept of mobilizing much of the international relations and community, to working together and preventing the occurrence of such events happening within history and the international society. Australian anthropologist Peg LeVine coined the term "ritualcide" to describe the destruction of a group's cultural identity without necessarily destroying its members.

Question:
Who ultimately defined genocide as a series of strategies leading up to the annihilation of an entire group?

Lemming
