First Sudanese Civil War
The First Sudanese Civil War (also known as the Anyanya Rebellion or Anyanya I, after the name of the rebels, a term in the Madi language which means 'snake venom') was a conflict from 1955 to 1972 between the northern part of Sudan and the southern Sudan region that demanded representation and more regional autonomy. Half a million people died over the 17 years and the war was divided into four major stages: initial guerrilla warfare, the creation of the Anyanya insurgency, political strife within the government and establishment of the South Sudan Liberation Movement.
