Attitudes of Governmental Elites on League of Nations and the Iran’s National Interest

International organizations have provided states with new opportunities to conduct foreign policy in the past hundred years. The League of Nations, established after WWI, was the first public international organization. This study emphasizes on the importance of this organization in the midst of two World Wars and measures the success and failure of Iranian diplomats at the League of Nations at securing Iran’s national interest. To answer this question, this study reviews the words and deeds of Iranian diplomats at the League of Nations. The creation of this organization is explained using the realist and idealist methods. Finally, we conclude that Iranian diplomats failed to effectively secure Iran’s national interest at the League of Nations because their understanding of international politics was different from reality.
