what was the league of nations and why did congress oppose joining

The League of Nations was an international organization founded in 1920 after the end of World War I. Its primary goal was to maintain world peace and prevent future conflicts by promoting disarmament, collective security, and negotiation of disputes among member nations.

The opposition from the United States Congress to joining the League of Nations can be attributed to a combination of factors. First and foremost, many members of Congress believed that joining the League would undermine the country's sovereignty and entangle the United States in foreign conflicts. They feared that decisions made by the League could potentially override American laws and policies.

Additionally, there was a sentiment among some congressmen that the League's lack of inclusion of certain major world powers, such as the Soviet Union, Germany, and Japan, weakened its credibility and effectiveness. Some argued that without the participation of these prominent countries, the League would not be capable of fulfilling its mission.

Furthermore, there were concerns about potential military obligations associated with the League. Some members of Congress worried that the United States would be compelled to go to war to enforce decisions made by the League, even if it conflicted with American national interests.

Ultimately, the Republican-controlled Senate refused to ratify the Treaty of Versailles, which included the provision for joining the League of Nations. This opposition led the United States to remain outside the League and adopt a policy of isolationism in the following decades.
