Washington Naval Conference

Washington Naval Conference

Washington (Disarmament) Naval Treaty (1922)

After World War I, many people were tired of war and arms races. The United States called for a conference to explore possibility of a disarmament treaty among nations. The conference was held outside auspices of the League of Nations. Nine nations attended: United States, Japan, China, France, Britain, Italy, Belgium, Nether-lands, Portugal. The resulting agreement effectively limited construction of new battleships and slowed the pace of arms races. The agreement was for a period of 14 years and was registered with the League of Nations. During WWI, Japan was an ally of Britain. The treaty granted Japan concessions on its control over parts of China and acknowledged its position as a Naval power in the western Pacific. Women were given the right to vote in 1920 in the United States. Some say that women suffrage contributed to the anti-war movement throughout the Western world.

London Naval Treaty of 1930

In the 1930’s there was still an arms race. No more battleships but the race took the form of building heavy cruisers and submarines. In early 1930, nations remained suspicious of each other. The London Naval Treaty of 1930 was created to limit further the number of submarines and size of guns. The USS Salt Lake City, ordered in 1926 as a light cruiser (CL25 designation) with 8 inch guns. Because of the size of guns, its designation was changed to CA25 (heavy cruiser).
