The British Military Administration (BMA) was the interim administrator of British Malaya from August 1945, the end of World War II, to the establishment of the Malayan Union in April 1946. The BMA was under the direct command of the Supreme Allied Commander South East Asia, Lord Louis Mountbatten. The administration had the dual function of maintaining basic subsistence during the period of reoccupation, and also of imposing the state structure upon which post-war imperial power would rest.
