Malaya united with North Borneo, Sarawak, and Singapore on 16 September 1963 to become Malaysia.

Document 10: History of Malaysia: Japanese invasion during World War II ended British domination in Malaysia. The subsequent occupation of Malaya, North Borneo and Sarawak from 1942 to 1945 unleashed nationalism. In the Peninsula, the Malayan Communist Party took up arms against the British. A tough military response was needed to end the insurgency and bring about the establishment of an independent, multi-racial Federation of Malaya on 31 August 1957. On 22 July 1963, Sarawak was granted a self - governance. The following month on 31 August 1963, both North Borneo and Singapore were also granted self - governance and all states began to formed Malaysia on 16 September 1963.

Document 12: 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.
