April 20: The League of Nations was officially dissolved in 1946 to make way and powers to the United Nations-UN-

US President Woodrw Wilson

The beginning of World War II showed that the League of Nations had failed in its main objective to prevent another world war. Although it was promoted by US President Woodrow Wilson with a famous speech of 14 points defending its creation, the US Senate did not approve the project or the entry into the League. The absence of US established a permanent weakness for that multilateral organization.

The last meeting of the League of Nations began on April 12, 1946 with delegates from 34 nations, and ended seven days later, on April 19, 1946.

The Assembly was summoned to settle the organization and transfer their assets to the nascent United Nations better known by the acronym UN (United Nations).

The League had no military might of its own and had to rely on its member nations to provide physical force if necessary.

Today The United Nations has 193 member nations of the planet's main multilateral organization that began with 51 founding members, with 34 having the League of Nations.
