The region has been affected by civil war for many years. It was a scene of fighting in the First Sudanese Civil War. In 1982, the Sudan People's Liberation Army (SPLA) was formed there by John Garang to fight the Northerners-dominated government in Khartoum. This was the beginning of what quickly became known as the Second Sudanese Civil War. The subsequent conflict lasted until 2003 and killed more than two million people. A substantial fraction of the population of the region is internally displaced or refugees in neighboring countries.
