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 The Philippines, which had withdrawn diplomatic recognition from Malaysia, also recognised Malaysia around the same time.
Monarchies of Malaysia
The present form of constitutional monarchy in Malaysia dates from 1957, when the Federation of Malaya gained independence. The rulers serve as constitutional heads of their states, with the state executive powers exercised by state governments elected by the people. The rulers elect among themselves a federal head of state, the Yang di-Pertuan Agong, with the federal executive powers exercised by an elected federal government. The form of constitutional monarchy was retained when Malaysia was formed in 1963.
