Pogrom

A pogrom is a violent riot aimed at massacre or persecution of an ethnic or religious group, particularly one aimed at Jews. The term originally entered the English language to describe 19th- and 20th-century attacks on Jews in the Russian Empire (mostly within the Pale of Settlement in present-day Ukraine and Belarus). Similar attacks against Jews at other times and places also became retrospectively known as pogroms. The word is now also sometimes used to describe publicly sanctioned purgative attacks against non-Jewish ethnic or religious groups.
