A pogrom is a violent riot aimed against a person or personal property based on the victim's ethnic, religious, or social background or lifestyle. It was originally used for race riots against Jewish communities, but has also been used since in reference to other groups. Historically many pogroms - particularly against Jews - were perpetrated with the tacit approval or even outright support of local rulers and non-Jewish businesspeople.
