According to the Rift Valley Institute, slave-raiding, "abduction … effectively ceased" in 2002. "A significant number" of slaves were repatriated after 2005 the Comprehensive Peace Agreement of 2005, but "an unknown number" remain in captivity. The Institute created a "Sudan Abductee Database" containing "the names of over 11,000 people who were abducted in 20 years of slave-raiding" in Northern Bahr el-Ghazal state in southern Sudan, from 1983 to 2002. The January 2005 "North/South Comprehensive Peace Agreement (CPA)" peace treaty that ended the Sudanese civil war put an end to the slave raids, according to Christian Solidarity International, but did not provide a "way home for those already enslaved." The last Human Rights Watch "Backgrounder on Slavery in Sudan" was updated March 2002.
