A massacre is an incident where some group is killed by another, and the perpetrating party are perceived to be in total control of force while the victimized party is perceived to be helpless and/or innocent with regard to any legitimate offense. There is no clear-cut definition for when killings are referred to as massacres or not, rather, this choice is a result of an individual or collective assessment, depending e.g. on how the circumstances of the killing align with given ideas of acceptable use of force and on the desired status of an event in collective memory.
The term massacre derives from the Latin term for mass sacrifice. The first recorded use in English of the word massacre in the name of an event is "Marlowe (c1600), The massacre at Paris" (a reference to the St. Bartholomew's Day massacre). Massacre can also be used as a verb, as "To kill (people or, less commonly, animals) in numbers, esp. brutally and indiscriminately".
