 Following the end of the First World War, Spain did not participate in the Washington Naval Conference which limited battleship construction for its signatories. Nevertheless, battleships of the 35,000-long-ton (36,000 t) displacement class — the limit under the Washington Naval Treaty — were considered by the Spanish Navy in the early 1920s. By the early 1930s, the navy made proposals for a "reduced Nelson type" ship, although nothing came of either project.
