After the fall of Addis Ababa, Ethiopian resistance was increasingly confined to the mountains and it appeared to most observers that the populace was ready to accept occupation and co-operate with Italian authorities; Selassie was concerned that his compatriots would adjust to Italian rule. But Viceroy Graziani's harsh measures against the Patriots and the general repression that occurred during his tenure eroded support for conciliation.[16] Prince Amedeo, Duke of Aosta was appointed by Mussolini to replace Graziani as Viceroy of Italian East Africa. He was more open-minded than his predecessor and well-suited to encourage the co-operation of the Ethiopian public, but by the time he assumed his responsibilities on 29 December 1937, Ethiopian opinion had soured on the notion of Italian domination.[17] Though most of the original Ethiopian Army had been destroyed, a new resistance network was established in Amhara by aristocrats that had escaped persecution in Addis Ababa and Orthodox clergymen who were disturbed by the Italian overtures to the Muslim population.[18]
