Name the international peacekeeping founded after WW1

The correct answer is: The League of Nations

Explanation:

The League of Nations, or Society of Nations, was an international organization founded on the proposal of the U. S. president Thomas Woodrow Wilson after World War I (1919).

Its fundamental goals were to maintain peace in the World, to prevent war through collective security, resolve disputes between countries through negotiated diplomacy, and improving global well-being. The League had three main branches: the secretariat (based in Geneva), the Council and the Assembly, and a certain number of commissions and agencies.

With the onset of World War II, it became clear that the League had failed in its fundamental mission - preventing future world wars. During the War, the League Council did not hold meetings, and the secretariat was relocated to North America. After failing to prevent the war, the League of Nations was replaced with a new body - United Nations.
