What was the league of nations?
why was it formed?

The League of Nations (1919 – 1946) was the first non-governmental international organization, founded during the Paris Peace Conference in 1919.

Its main objective was to maintain world peace after World War I.

Explanation:

The League had three main organs: the secretariat (led by the Secretary-General), the Council, and the Assembly and a large number of commissions and agencies.

The other goals of the League were: preventing war through collective security, resolving disputes between countries through diplomacy, and improving global well-being.

The most important achievements of the League were: resolving a dispute between Sweden and Finland, preventing the economic crisis in Austria and the outbreak of the war in the Balkans, and supporting the administrative division of the Saar region in Germany.

With the onset of World War II, The League of Nation failed in its essential objective - to prevent future world wars and aggression. During the war, the Assembly did not hold meetings, the Secretariat from Geneva was reduced to a minimum and relocated most of its employees to North America. After World War II the League was replaced with the United Nations.
