A massacre is the killing of a large number of people, especially those who are not involved in any fighting or have no way of defending themselves. A massacre is generally considered to be morally unacceptable, especially when perpetrated by a group of political actors against defenseless victims. The word is a loan of a French term for "butchery" or "carnage". A "massacre" is not necessarily a "crime against humanity". Other terms with overlapping scope include war crime, pogrom, mass killing, mass murder, and extrajudicial killing.
