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 The Philippines, which had withdrawn diplomatic recognition from Malaysia, also recognised Malaysia around the same time.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
Historically, various Malay kingdoms flourished on the Malay peninsula. The earliest kingdoms were influenced by Hindu culture, the most notable being Langkasuka in present-day Kedah. In the 15th century, the Malacca Sultanate became the dominant power on the peninsula. The Malacca Sultanate was the first Malay Muslim state based on the peninsula that was also a real regional maritime power. After the fall of Malacca in 1511, several local rulers emerged in the northern part of the peninsula which later fell under Siamese influence, while two princes of the Malaccan royal family founded Johor and Perak respectively. The Sultanate of Johor emerged as the dominant power on the peninsula. The vast territory of Johor led to some areas gaining autonomy, which gradually developed into independent states.
