The League of Nations is primarily remembered for its failures in the 1930s. Indeed, the established perception of its history usually emphasizes weaknesses. Failing to settle the question of which Power should possess the former Ottoman province of Mosul after the First World War, Turkey saw the dispute addressed to the League in summer 1924. Within a short time, a multi-leveled negotiation process that involved a large number of politicians, diplomats, and lawyers was put in motion. Sixteen months and many crises later, the League Council awarded the entire Mosul province to Iraq. The arbitration had been based upon data collected by two enquiry commissions comprising representatives from eight different Powers, the work of both numerous mediators, and a Council sub-committee. Though certainly not perfect, the League's role averted war and renewed disaster.
