In this essay, I am going to look at the successes and failures of the League of Nations (LofN) in its struggle for peace throughout the 1920’s. The LofN was the ‘brain child’ of American president Woodrow Wilson. The four other main powers (Britain, France, Japan and Italy) joined along with approximately 60 other countries from around the world.

Neither Sweden nor Finland could come to a decision as to who owned the islands and in 1921 they asked the LofN to adjudicate. The League’s decision was that they should remain Finish, but that no weapons should ever be kept there. Both countries accepted the LofN’s decision. This sent out many positive signs at the time to the world.

Vilna was made the capital city of Lithuania, but its population was mainly Polish, and in 1920 the Polish Army took control of it. Lithuania appealed for help. This was the first crucial ‘test case’ for the LofN. Both countries were members of the League. Poland was clearly
