It achieved a number of successes: the Permanent Court of Justice (now the International Court of Justice) was associated with it.
The League however, had a number of weaknesses - the United States did not join: other states which were not members for part or all of the time included the Soviet Union, Germany and Italy. It was unable to handle the Spanish Civil War and the Italian invasion of Abyssinia (in OTL leading to Haille Sellassie addressing the League), and was disbanded in 1946, with the United Nations being in effect its successor body.
