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 fought from 1955 to 1972 between the northern part of Sudan and the southern Sudan region which demanded representation and more regional autonomy. 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 Southern Sudan Liberation Movement. Around a million people died over the course of the nearly 17-year long war. Although the Addis Ababa Agreement ended the war in 1972, it failed to completely dispel the tensions and addressed only some of the issues stated by southern Sudan.
