In 1956, when Ethiopia was under the reign-ship of Haile Selassie, Sudan achieved the independency from the British colony. But they not come in to peace, for the Government of Sudan supports the armed groups, Eritrean Liberation Front and Eritrean People Liberation Front, along the Ethiopia-Sudan border that fought against Haile Selassie’s government.[1] Following this the Imperial government of Ethiopia obligated to support the rebel movement in South Sudan known as Anya Nya. This put Sudan into the first civil war which was took between 1955 to 1972.[2][4]
