League of Nations Convenes: Treaty of Versailles Ratified

The League of Nations held its first council meeting on January 10, 1920, and immediately confronted its most crippling deficiency: the United States, whose president had conceived and championed the organization through two years of grueling negotiations, was not a member. The U.S. Senate had rejected the Treaty of Versailles in November 1919, with opponents arguing that Article X of the League Covenant could commit American troops to foreign conflicts without congressional approval. Senator Henry Cabot Lodge led the opposition, insisting on reservations that Woodrow Wilson refused to accept. Wilson''s stubbornness proved as fatal to the League as Lodge''s isolationism. Without the world''s largest economy and its emerging military power, the League lacked enforcement capability from day one. The forty-two founding members could pass resolutions and impose sanctions, but they could not compel compliance from any major power willing to absorb the diplomatic cost of defiance. The institution was born with its most important muscle severed. The League achieved some early successes that are largely forgotten. It resolved the Aaland Islands dispute between Sweden and Finland in 1921. It repatriated 400,000 prisoners of war still scattered across Europe after the Great War. Its health organization conducted campaigns against malaria, leprosy, and yellow fever. The International Labour Organization, established as a League agency, set standards for working conditions that influenced labor law worldwide. The Nansen passport system provided identity documents for stateless refugees. These accomplishments could not survive the challenges of the 1930s. When Japan invaded Manchuria in 1931, the League condemned the aggression. Japan withdrew from the organization. When Italy attacked Ethiopia in 1935, the League imposed economic sanctions but exempted oil, the one commodity that could have crippled Mussolini''s military. Member states prioritized their own trade relationships over collective security. The organization limped through the late 1930s as a talking shop while fascist aggression dismantled the post-war order it was supposed to protect. It was formally dissolved in 1946, its assets transferred to the United Nations.
