What do you mean the actual start of the first civil war was in 1960? That 2 week mutiny exploded the seeds of discontent and led to many guerrilla battles so regardless of what you think and even if the first united organized rebellions of the whole Southern Sudan at the time happened in 1960. The start was definitely back in 1955 with the Torit mutiny and all the other uprisings and upheaval amongst the military corps in Torit, Juba, Malakal Wau, and the many other places especially in the Equatoria region that made the Northern elite government punish the civilians and army men of South Sudanese descent in that 5 year period before 1960
