History of Malaysia
After reviewing the Cobbold Commission's findings, the British government appointed the Landsdowne Commission to draft a constitution for Malaysia. The eventual constitution was essentially the same as the 1957 constitution, albeit with some rewording; for instance, giving recognition to the special position of the natives of the Borneo States. North Borneo, Sarawak and Singapore were also granted some autonomy unavailable to the states of Malaya. After negotiations in July 1963, it was agreed that Malaysia would come into being on 31 August 1963, consisting of Malaya, North Borneo, Sarawak and Singapore. The date was to coincide with the independence day of Malaya and the British giving self-rule to Sarawak and North Borneo. However, Indonesia and the Philippines strenuously objected to this development, with Indonesia claiming Malaysia represented a form of "neocolonialism" and the Philippines claiming North Borneo as its territory. The opposition from the Indonesian government led by Sukarno and attempts by the Sarawak United People's Party delayed the formation of Malaysia. Due to these factors, an eight-member UN team was formed to re-ascertain whether North Borneo and Sarawak truly wanted to join Malaysia. Malaysia formally came into being on 16 September 1963, consisting of Malaya, North Borneo, Sarawak, and Singapore. In 1963 the total population of Malaysia was about 10 million.
Sabah
The earliest human settlement in Sabah can be traced back to 20,000–30,000 years ago along the Darvel Bay area at the Madai-Baturong caves. The state had a trading relationship with China from the 14th century AD. Sabah came under the influence of the Bruneian Empire in the 14th–15th century while the eastern part of the territory fell under the influence of Sultanate of Sulu between the 17th–18th centuries. The state was subsequently acquired by the British-based North Borneo Chartered Company in the 19th century. During World War II, Sabah was occupied by the Japanese for three years. It became a British Crown Colony in 1946. On 31 August 1963, Sabah was granted self-government by the British. Following this, Sabah became one of the founding members of the Federation of Malaysia (established on 16 September 1963) alongside Sarawak, Singapore (expelled in 1965), and the Federation of Malaya (Peninsular Malaysia or West Malaysia). The federation was opposed by neighbouring Indonesia, which led to the Indonesia–Malaysia confrontation over three years along with the threats of annexation by the Philippines, threats which continue to the present day.
