Oil, Genocide, and Civil War: The Challenges of Bringing Peace to Sudan and South Sudan

South Sudan gained independence from Sudan in 2011 as a result of a peace process that ended Africa’s longest-running civil war. Ambassador Princeton N. Lyman became the United States Special Envoy for Sudan in March 2011. Immediately preceding his tenure as Special Envoy, he served as U.S. Senior Advisor on North-South Negotiations, where he led the U.S. team focused on supporting negotiations between the parties to Sudan’s 2005 Comprehensive Peace Agreement.
