Human Rights Watch and others have described the contemporary form of slavery in Sudan as mainly the work of the armed, government-backed militia of the Baggara tribes who raid civilians—primarily of the Dinka ethnic group from the southern region of Bahr El Ghazal. The Baggara captured children and women who were taken to western Sudan and elsewhere. They were "forced to work for free in homes and in fields, punished when they refuse, and abused physically and sometimes sexually". The government of Sudan "arm[ed] and sanction[ed] the practice of slavery by this tribal militia", known as "muraheleen", as a low cost way of weakening its enemy in the Second Sudanese Civil War, the rebel Sudan People's Liberation Movement/Army (SPLM/A), which was thought to have a base of support among the Dinka tribe of southern Sudan.
