The origins of the civil war in the south date back to the 1950s. On August 18, 1955, the Equatoria Corps, a military unit composed of southerners, mutinied at Torit. Rather than surrender to Sudanese government authorities, many mutineers disappeared into hiding with their weapons, marking the beginning of the first war in southern Sudan. By the late 1960s, the war had resulted in the deaths of about 500,000 people. Several hundred thousand more southerners hid in the forests or escaped to refugee camps in neighboring countries.
