The League of Nations was founded with the aim of preventing international clashes and the resolution of inter-state friction. The system of collective security, based on the good will of the countries involved, was considered after the end of the First World War to be the most convenient method of maintaining stability.
The Greek-Bulgarian incident of 1925 and the Abyssinian crisis a decade later demonstrated the structural weaknesses of the new supra-state organization. The declared aim of the peaceful settlement of disputes between individual states ended up being implemented only insofar as it served the interests of the Great Powers. The dominance of the strong countries in the League of Nations became possible mainly through their influence over its basic executive mechanism, the Council of Nations. The submissive and self-seeking attitude towards regional conflicts and inter-state crises on the part of the international organization did not manage to prevent the second great clash to shake the world in the 20th century.
