United Malays National Organisation
The Philippines and Indonesia strenuously objected to this development, with Indonesia claiming Malaysia represented a form of neocolonialism and the Philippines claiming Sabah as its territory. The United Nations sent a commission to the region which approved the merger after having delayed the date of Malaysia's formation to investigate. Despite further protests from the Indonesian President, Sukarno, the formation of Malaysia was proclaimed on 16 September 1963. Indonesia then declared a "confrontation" with Malaysia, sending commandos to perform guerilla attacks in East Malaysia (Sabah and Sarawak). The confrontation was ended when a military coup replaced Sukarno with Suharto. The Philippines, which had withdrawn diplomatic recognition from Malaysia, also recognised Malaysia around the same time.
History of Malaysia
Although Muslims had passed through the Malay Peninsula as early as the 10th century, it was not until the 14th century that Islam first firmly established itself. The adoption of Islam in the 14th century saw the rise of a number of sultanates, the most prominent of which was the Sultanate of Malacca. Islam had a profound influence on the Malay people, but has also been influenced by them. The Portuguese were the first European colonial powers to establish themselves on the Malay Peninsula and Southeast Asia, capturing Malacca in 1511, followed by the Dutch in 1641. However, it was the British who, after initially establishing bases at Jesselton, Kuching, Penang and Singapore, ultimately secured their hegemony across the territory that is now Malaysia. The Anglo-Dutch Treaty of 1824 defined the boundaries between British Malaya and the Netherlands East Indies (which became Indonesia). A fourth phase of foreign influence was immigration of Chinese and Indian workers to meet the needs of the colonial economy created by the British in the Malay Peninsula and Borneo.
