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.
History of Sudan (1969–85)
Having survived the SCP-inspired coup, Nimeiri reaffirmed his commitment to establishing a socialist state. A provisional constitution, published in August 1971, described Sudan as a "socialist democracy" and provided for a presidential form of government to replace the RCC. A plebiscite the following month elected Nimeiri to a six-year term as president.
