Gang rape

Nature

In scholarly literature and criminology, gang rape, also called serial gang rape, party rape, group rape, or multiple perpetrator rape, is the rape of a single victim by two or more violators. Gang rapes are forged on shared identity, religion, ethnic group, or race. There are multiple motives for serial gang rapes, such as for sexual entitlement, asserting sexual prowess, war, punishment, and, in up to 30% of cases, for targeting racial minorities, religious minorities, or ethnic groups.

Gang rapes can be part of genocidal rape or ethnic cleansing campaigns.
