Military regimes favoring Islamic-oriented governments have dominated national politics since independence from Anglo-Egyptian co-rule in 1956. Sudan was embroiled in two prolonged civil wars during most of the remainder of the 20th century. These conflicts were rooted in northern economic, political, and social domination of largely non-Muslim, non-Arab southern Sudanese. South Sudan became independent on 9 July 2011. A separate conflict, which broke out in the western region of Darfur in 2003, displaced nearly two million people. Violence in Darfur in 2013 resulted in an additional estimated 500,000 displaced. The UN and the African Union have jointly commanded a Darfur peacekeeping operation known as the African Union-United Nations Hybrid Mission in Darfur since 2007. Peacekeeping troops have struggled to stabilize the situation and have increasingly become targets for attacks by armed groups. Sudan also has faced refugee influxes from neighboring countries, primarily Ethiopia, Eritrea, Chad, Central African Republic, and South Sudan. Armed conflict, poor transport infrastructure, and government denial of access have impeded the provision of humanitarian assistance to affected populations.
