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 The Philippines, which had withdrawn diplomatic recognition from Malaysia, also recognised Malaysia around the same time.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
From the 15th century onwards, the Portuguese started seeking a maritime route towards Asia. In 1511, Afonso de Albuquerque led an expedition to Malaya which seized Malacca with the intent of using it as a base for activities in southeast Asia. This was the first colonial claim on what is now Malaysia. The son of the last Sultan of Malacca, Sultan Alauddin Riayat Shah II fled to the southern tip of the peninsula, where he founded a state that which became the Sultanate of Johor. Another son created the Perak Sultanate to the north. By the late 16th century, the tin mines of northern Malaya had been discovered by European traders, and Perak grew wealthy on the proceeds of tin exports. Portuguese influence was strong, as they aggressively tried to convert the population of Malacca to Catholicism. In 1571, the Spanish captured Manila and established a colony in the Philippines, reducing the Sultanate of Brunei's power.
After the fall of Malacca to Portugal, the Johor Sultanate and the Sultanate of Aceh on northern Sumatra moved to fill the power vacuum left behind. The three powers struggled to dominate the Malay peninsula and the surrounding islands. Johor founded in the wake of Malacca's conquest grew powerful enough to rival the Portuguese, although it was never able to recapture the city. Instead it expanded in other directions, building in 130 years one of the largest Malay states. In this time the numerous attempts to recapture Malacca led to a strong backlash from the Portuguese, whose raids even reached Johor's capital of Johor Lama in 1587.
