League of Nations Founded
The League of Nations formally came into existence on 10 January 1920 as an integral part of the Versailles settlement, institutionalising Woodrow Wilson's vision of collective security and a rules-based international order. Forty-two states initially joined; the Covenant committed members to respect each other's territorial integrity and to submit disputes to arbitration. The system included an Assembly where all members voted equally, a Council dominated by great powers, a Permanent Court of International Justice, and specialised agencies for labour, health, and refugees that proved more durable than the organisation's security functions. The United States Senate refused to ratify the Covenant in November 1919 and again in March 1920, rejecting membership twice and leaving the body without its most powerful sponsor. Germany was excluded until 1926; the Soviet Union until 1934 (and expelled in 1939). Without US participation, enforcement mechanisms, or an independent military force, the League relied on moral authority and the willingness of Britain and France — both exhausted and facing domestic pressure against foreign commitments — to act. It proved unable to stop Japanese seizure of Manchuria in 1931, Italian invasion of Ethiopia in 1935, or German remilitarisation of the Rhineland in 1936, demonstrating the fatal gap between collective security ambition and political will.
