Being in command of the municipal police, which he organized along modern lines, Nasibu played a key role in the political power struggle of 1928, supporting Ras Tafari (the later Emperor Haile Selassie) against first Dejazmach Balcha Safo then against Dejazmach Abba Weqaw. In 1930, Nasibu Emmanual was appointed as the Director of the Ministry of War by Emperor Haile Selassie. He was considered by many to be un-Ethiopian because he was mission educated. He was also considered un-Ethiopian because he spoke Italian and French and because he dressed in modern European clothing and uniforms.Marcus, The Life and Times of Menelik II: Ethiopia 1844-1913, p. 134 In 1931, Nasibu Emmanual was named Dejazmach and Shum of Gurage Province and Soddo Province. In 1932, he became Shum of Bale Province.Haile Selassie, p. 4
