• The League of Nations was an international organization established after the Great War.
• It was founded in January of 1920.
• The league was meant to prevent conflicts through collective security.
• The idea was that if a conflict were to occur, another nation would intervene and attempt to stop the conflict by negotiating, and if that didn't work, through force.
• However the idea wasn't employed to great affect as many nations didn't already support the league, and the main faces of the league being France and Great Britain were focused more on their own affairs.
• Although successful in some scenarios, the League was generally ineffective as it was made to enforce the flawed Treaty of Versailles.
• For example, the U.S.A. didn’t join the League due to their foreign policy of not interacting with European affairs. This was drastic as the U.S.A. was the most industrially and economically powerful country at the time, and it was one of President Woodrow Wilson's main ideas to have collective security in the first place.
• Germany, USSR and Italy left the league in later years.
