First Sudanese Civil War
The Coup d'état of Chief of Staff Lt. Gen. Ibrahim Abboud
Southern Sudan
The government was unable to take advantage of rebel weaknesses because of their own factionalism and instability. The first independent government of Sudan, led by Prime Minister Ismail al-Azhari, was quickly replaced by a stalemated coalition of various conservative forces, which was in turn overthrown in the coup d'état of Chief of Staff Lt. Gen. Ibrahim Abboud in 1958.
