League of Nations
IV. World Involvement

The league was based on a new concept: collective security against the “criminal” threat of war. Unfortunately, the league rarely implemented its available resources, limited though they were, to achieve this goal.

One important activity of the league was the disposition of certain territories that had been colonies of Germany and the Ottoman Empire before World War I. Supervision of these territories was awarded to league members in the form of mandates. Mandated territories were given different degrees of independence, in accordance with their stage of development, their geographic situation, and their economic status.

The league may be credited with certain social achievements. These include curbing international traffic in narcotics and prostitution, aiding refugees of World War I, and surveying and improving health and labor conditions around the world.

In the area of preserving peace, the league had some minor successes, including settlement of disputes between Finland and Sweden over the Åland Islands in 1921 and between Greece and Bulgaria over their mutual border in 1925. The Great Powers, however, preferred to handle their own affairs; France occupied the Ruhr, and Italy occupied Corfu (Kérkira), both in 1923, in spite of the league.

Although Germany joined the league in 1926, the National Socialist (Nazi) government withdrew in 1933. Japan also withdrew in 1933, after Japanese attacks on China were condemned by the league. The league failed to end the war between Bolivia and Paraguay over the Chaco Boreal between 1932 and 1935 and to stop the Italian conquest of Ethiopia begun in 1935.

Finally, the league was powerless to prevent the events in Europe that led to World War II. The USSR, a member since 1934, was expelled following the Soviet attack on Finland in 1939. In 1940 the secretariat in Geneva was reduced to a skeleton staff, and several small service units were moved to Canada and the United States.

In 1946 the league voted to effect its own dissolution, whereupon much of its property and organization were transferred to the UN.
