Background [edit]. Both Italy and Abyssinia were members of the League of Nations (founded in June 1919 at the Paris Peace Conference). Italy was a founding member of the league. Abyssinia joined on September 28, 1923, seven years after Ras Tafarai Makonnen was appointed the head of state as HIM Haile Selassie I.Article X of the league's rules explicitly forbade aggression among its members.n January 3, 1935, Ethiopia appealed to the League of Nations for arbitration of the dispute arising from the Walwal incident. But the league's response was inconclusive. A subsequent analysis by an arbitration committee of the League of Nations absolved both parties of any culpability for what had happened.
