EXPLANATIONS BELOW
Concept note-1: -The Treaty of Versailles included a plan to form a League of Nations that would serve as an international forum and an international collective security arrangement. U.S. President Woodrow Wilson was a strong advocate of the League as he believed it would prevent future wars.
Concept note-2: -29.5. 4: The League of Nations. The League of Nations was formed to prevent a repetition of the First World War, but within two decades this effort failed. Economic depression, renewed nationalism, weakened successor states, and feelings of humiliation (particularly in Germany) eventually contributed to World War II.
Concept note-3: -The first, and most significant, was the Treaty of Versailles, signed on June 28, 1919.
Concept note-4: -The Treaty of Versailles was signed in the Palace of Versailles Hall of Mirrors on 28 June 1919. The Covenant of the League of Nations was integrated into the Treaty and all other peace settlements signed in Paris after World War I.
Concept note-5: -The League Council acted as a type of executive body directing the Assembly’s business. It began with four permanent members – Great Britain, France, Italy, and Japan – and four non-permanent members that were elected by the Assembly for a three-year term.
