The League of Nations was the idea of President Wilson of the US. It was formed as a result of the Versailles conference and its rules were consolidated into each of the treaties agreed at the conference. The defeated nations had no say in the treaties and were not allowed to join the League. Therefore, these countries saw the league as in some way connected to the hated peace treaties. The League had some successes in the 1920s, but some historians have argued that it was doomed to failure from the start.
The League had so many weaknesses which lead to its failure as an international peacekeeping organisation.

So, this would make the League an organisation that doesn’t bring peace.
Another cause of the League not being fully effective is that the League was dominated by France and Britain. Britain and France often made decisions based on their own interests as they were weak in terms of military power and economically due to the impact of World War One.

This is why, the League seemed weak when Poland took Vilna and Mussolini took Corfu. Furthermore, the League appeared powerless and was overruled by countries who were not a member of the League.
The final reason for the League not being fully effective was the organisation of the League. Each…
