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 The Philippines, which had withdrawn diplomatic recognition from Malaysia, also recognised Malaysia around the same time.
Selangor
The Federated Malay States evolved into the Federation of Malaya in 1948, which became independent in 1957 and was renamed Malaysia in 1963. The city of Kuala Lumpur functioned as the national capital of Malaysia and as the state capital of Selangor. In 1974, Selangor relinquished Kuala Lumpur to the federal government. The Sultan of Selangor commemorated the city's transfer by building an archway on the borders of the new Federal Territory and Selangor; this archway is the Kota Darul Ehsan that straddles a section of the Federal Highway between Bangsar and Petaling Jaya. The state capital was moved to Shah Alam after the cession.
