Please give a short overview what the League of Nations was and why it was found.

The League of Nations was an international organization which resulted out of the Paris Peace Conference that eventually ended the First World War. Even though then U.S.-President Woodrow Wilson initiated the idea, the United States themselves never became an actual member thereof. However, the League of Nations became the first important organ of International Law that offered a stage to discuss matters and disputes in between states peacefully. Contracts and pacts from that time not only promoted peaceful settlements, but also offered first institutionalized instruments for countries to comply. This was particularly important, after the First World War had not only shown the increase of destructive power new technologies and scientific advances could cause, but had also resulted out of numerous entangled pacts and treaties between states which caused the war to unfold quickly within Europe and beyond. Furthermore, new states and countries emerged out of the WW1, that had caused the Habsburg and the Ottoman Empires too collapse. These had to be incorporated in the international system and their transition supported. Even though the Second World War quickly unveiled the limits of the power and influence of the League of Nations, its concept, treaties and organs were all transferred into the new United Nations and therefore shape the world we have until this very day.
