This is an international organization whose goals included disarmament; preventing war through collective security; settling disputes between countries through negotiation and diplomacy and improving global welfare, it was to be formed after world war i. term:
I believe the answer is League of Nations. League of Nation was created after Paris conference in 1920. This conference officially ended the World War I, and the league of nations was created to maintain the world peace and prevent similar wars from happening again in the future. (they failed since we have to fought in world war II less than 20 years later)
