In December 1948, 24 villagers were executed by British troops. From 1949 the MCP campaign lost momentum and the number of recruits fell sharply. Although the MCP succeeded in assassinating the British High Commissioner, Sir Henry Gurney, in October 1951, this turn to terrorist tactics alienated many moderate Chinese from the Party.

Against this backdrop, independence for the Federation within the Commonwealth was granted on 31 August 1957, with Tunku Abdul Rahman as the first prime minister.
