law and genocide

Genocide is first and foremost, a legal concept. It is also used in other contexts and by other disciplines where its meaning may vary. But even in law it is imprecise to speak of a single, universally recognized meaning of genocide. Many historians and sociologists employ the word to describe a range of atrocities involving killing large numbers of people. The crime of genocide has been incorporated within the legal systems of many countries.The term was invented by a lawyer, Rapael Lemkin
