 In the aftermath of the First World War, the Washington Naval Treaty was drawn up in 1922 in an effort to stop an arms race developing between Britain, Japan, France, Italy and the United States. This treaty limited the number of ships each nation was allowed to build and capped the tonnage of all capital ships at 35,000 tons. These restrictions were extended in 1930 through the Treaty of London, however, by the mid-1930s Japan and Italy had withdrawn from both of these treaties, and the British became concerned about a lack of modern battleships within their navy. As a result, the Admiralty ordered the construction of a new battleship class: the King George V class. Due to the provisions of both the Washington Naval Treaty and the Treaty of London, both of which were still in effect when the King George Vs were being designed, the main armament of the class was limited to the 14-inch (356 mm) guns prescribed under these instruments. They were the only battleships built at that time to adhere to the treaty, and even though it soon became apparent to the British that the other signatories to the treaty were ignoring its requirements, it was too late to change the design of the class before they were laid down in 1937.
