One of the primary aims of the League of Nations was to promote international cooperation. The League of Nations believed that all the different nations and countries in the world should be in peace, and they highly believed in world peace. The League of Nations was formed after the end of World War I. Because of World War I, the government didn't like to see nations going to war against each other, so they made this organization in order for nations to come together and cooperation among each other. The League of Nations soon failed because of World War II, which countered against their goal to have world peace.
