History of Sudan
The modern Republic of Sudan was formed in 1956 and inherited its boundaries from Anglo-Egyptian Sudan, established in 1899. For times predating 1899, usage of the term "Sudan" for the territory of the Republic of Sudan was somewhat anachronistic, and may have referred to the more diffuse concept of the Sudan.

Dissatisfaction culminated in a second coup d'état on 25 May 1969. The coup leader, Col. Gaafar Nimeiry, became prime minister, and the new regime abolished parliament and outlawed all political parties. Disputes between Marxist and non-Marxist elements within the ruling military coalition resulted in a briefly successful coup in July 1971, led by the Sudanese Communist Party. Several days later, anti-communist military elements restored Nimeiry to power.
In 1972, the Addis Ababa Agreement led to a cessation of the north-south civil war and a degree of self-rule. This led to ten years hiatus in the civil war but less happily an end to American investment in the Jonglei Canal project. This had been considered absolutely essential to irrigate the Upper Nile region and to prevent an environmental catastrophe and wide-scale famine among the local tribes, most especially the Dinka. In the civil war that followed their homeland was raided looted, pillaged and burned. Many of the tribe were murdered in a bloody civil war that raged for over 20 years.
Until the early 1970s, Sudan's agricultural output was mostly dedicated to internal consumption. In 1972, the Sudanese government became more pro-Western, and made plans to export food and cash crops. However, commodity prices declined throughout the 1970s causing economic problems for Sudan. At the same time, debt servicing costs, from the money spent mechanizing agriculture, rose. In 1978, the IMF negotiated a Structural Adjustment Program with the government. This further promoted the mechanized export agriculture sector. This caused great hardship for the pastoralists of Sudan (see Nuba peoples). In 1976, the Ansars had mounted a bloody but unsuccessful coup attempt. But in July 1977, President Nimeiry met with Ansar leader Sadiq al-Mahdi, opening the way for a possible reconciliation. Hundreds of political prisoners were released, and in August a general amnesty was announced for all oppositionists.
