Document 5: History of Malaysia: The Malayan Emergency as it was known, lasted from 1948 to 1960, and involved a long anti-insurgency campaign by Commonwealth troops in Malaya. The British strategy, which proved ultimately successful, was to isolate the MCP from its support base by a combination of economic and political concessions to the Chinese and the resettlement of Chinese squatters into “New Villages” in “white areas” free of MCP influence. 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. The arrival of Lt.-Gen Sir Gerald Templer as British commander in 1952 was the beginning of the end of the Emergency. Templer invented the techniques of counter-insurgency warfare in Malaya and applied them ruthlessly. Although the insurgency was defeated Commonwealth troops remained with the backdrop of the Cold War. 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.

Document 7: British Empire: Following the defeat of Japan in the Second World War, anti-Japanese resistance movements in Malaya turned their attention towards the British, who had moved to quickly retake control of the colony, valuing it as a source of rubber and tin. The fact that the guerrillas were primarily Malayan-Chinese Communists meant that the British attempt to quell the uprising was supported by the Muslim Malay majority, on the understanding that once the insurgency had been quelled, independence would be granted. The Malayan Emergency, as it was called, began in 1948 and lasted until 1960, but by 1957, Britain felt confident enough to grant independence to the Federation of Malaya within the Commonwealth. In 1963, the 11 states of the federation together with Singapore, Sarawak and North Borneo joined to form Malaysia, but in 1965 Chinese-majority Singapore was expelled from the union following tensions between the Malay and Chinese populations. Brunei, which had been a British protectorate since 1888, declined to join the union and maintained its status until independence in 1984.
