World War II

The war that preceded and was a catalyst for the creation of the United Nations was World War II.

Explanation:

The creation of the United Nations (UN) took place in February 1945, in the city of San Francisco, United States, as a result of the peace conferences held at the end of World War II. Initially, 50 countries signed the Charter of the United Nations, excluding those that were part of the Axis. The UN was a second attempt to create a union of nations in order to establish friendly relations between countries. The first attempt came with the formation of the League of Nations, at the end of World War I, but it failed in its objectives. The Charter affirms in its preamble that it is intended to preserve future generations from the scourge of war, seeking to consolidate their faith in fundamental human rights, in dignity, in the value of the human person, in the equality of rights between men and women of large and small nations. Its primary objective was to preserve international peace and guarantee security for that purpose, taking effective collective measures to prevent and eliminate all threats by peaceful means in accordance with the principles of justice and international law.
