In 1953 United Kingdom and Egypt reached an agreement to grant Sudan independence, which would be finally achieved on 1st January 1956. After this period there was another of economic and political difficulties which paralysed the public administration. In 1958 Ibrahim Abboud caused a coup d'etat and proclaimed himself Prime Minister.

But Abboud did not undertake the reforms he had promised to return Sudan to civil government. To this a movement of popular resentment was added, which forced the army to take power in October 1964. Abboud was overthrown by troops from the south who were looking for greater participation in national politics. In 1969 a new military coup d'etat brought General Gaafar al-Nimeiry to power, who after re-establishing order in the country became Sudan's first president.
