What is the difference between a massacre and a genocide?
While both terms refer to the intentional killing of large numbers of people, there is a key difference between a massacre and a genocide. A genocide is specifically defined as the deliberate and systematic destruction of a racial, ethnic, or religious group. In other words, a genocide is aimed at wiping out an entire group of people based on their identity, while a massacre can be motivated by a variety of factors, such as political or ideological beliefs.
What is the origin of the word "massacre"?
The word "massacre" comes from the Latin word "massa," meaning "a large crowd or multitude," and the French word "casser," meaning "to kill." The term was first used in the 16th century to describe the killing of a large number of people, often for political or religious reasons. Over time, the term has come to be used more broadly to describe any incident where many people are killed, regardless of the motivation behind it.
