Introduction

League of Nations, international alliance for the preservation of peace. The league existed from 1920 to 1946. The first meeting was held in Geneva, on November 15, 1920, with 42 nations represented. The last meeting was held on April 8, 1946; at that time the league was superseded by the United Nations (UN). During the league's 26 years, a total of 63 nations belonged at one time or another; 28 were members for the entire period (see accompanying table).
