Malaysia is a country in Southeast Asia. The federal constitutional monarchy consists of thirteen states and three federal territories, separated by the South China Sea into two regions: Peninsular Malaysia and Borneo's East Malaysia. Peninsular Malaysia shares a land and maritime border with Thailand and maritime borders with Singapore, Vietnam, and Indonesia. East Malaysia shares land and maritime borders with Brunei and Indonesia, and a maritime border with the Philippines and Vietnam. Kuala Lumpur is the national capital, the country's largest city, and the seat of the legislative branch of the federal government. The nearby planned capital of Putrajaya is the administrative capital, which represents the seat of both the executive branch (the Cabinet, federal ministries, and agencies) and the judicial branch of the federal government. With a population of over 32 million, Malaysia is the world's 45th-most populous country. The southernmost point of continental Eurasia is in Tanjung Piai. In the tropics, Malaysia is one of 17 megadiverse countries, home to numerous endemic species.
Malaysia has its origins in the Malay kingdoms, which, from the 18th century on, became subject to the British Empire, along with the British Straits Settlements protectorate. Peninsular Malaysia was unified as the Malayan Union in 1946. Malaya was restructured as the Federation of Malaya in 1948 and achieved independence on 31 August 1957. The independent Malaya united with the then British crown colonies of North Borneo, Sarawak, and Singapore on 16 September 1963 to become Malaysia. In August 1965, Singapore was expelled from the federation and became a separate independent country.
