In some regions of Ethiopia, abduction and rape is a cultural practice used to take a girl as wife by force. Typically, the girl is abducted by a group of young men, and then raped by the man who wants to marry her-either someone she knows, or a total stranger. Elders from the man's village then ask the family of the girl to agree to the marriage; the family often consents because a girl who has lost her virginity would be socially unacceptable for marriage to another man. Sometimes the abductor keeps the girl in a hiding place until she is pregnant, at which time the family again feels it has no option but to agree to the marriage.
It may seem unlikely a victim would willingly marry the perpetrator of her abduction and rape. However, with social and cultural pressure from families and the community, as well as threats from the offender, the girl will often "consent" to marry her perpetrator.
Both abduction and rape are criminal offences under Ethiopian law, but if marriage is subsequently agreed, the husband is exempt from criminal responsibility for his crimes.
