The conflict that broke out in Sudan on the eve of its independence from Britain in 1956 has devastated the country, retarded developmental progress, drained human resources and damaged the social fabric of the entire nation. However, the Protocol of Machakos which was signed by the Government of the Republic of the Sudan and the Sudan People’s Liberation Movement/Sudan People’s Liberation Army on 20 July 2002, states the commitment of the parties to a negotiated, peaceful and comprehensive resolution to the conflict within the unity of the country. With peace now in sight, the disarmament, demobilisation and reintegration (DDR) of former combatants is essential to avoid the mistakes made in 1972. It is crucial to build a new future for the generations that have suffered so much in five decades of war. This paper examines the challenges that might confront DDR in post-conflict Sudan. It draws on past experience following the 1972 Addis Ababa Agreement between the regime of President Gaffar Mohammed Nimeiri and the Anya-nya rebels, and on the experiences of countries that have gone through similar situations, such as Ethiopia, Mozambique and Uganda.
