Kuala Lumpur (KL), officially the Federal Territory of Kuala Lumpur, is the capital city and a federal territory of Malaysia. It is the most populous city in the country, covering an area of 243 km (94 sq mi) with a census population of 2,075,600 as of 2024. Greater Kuala Lumpur, also known as the Klang Valley, is an urban agglomeration of 8.8 million people as of 2024. It is among the fastest growing metropolitan regions in Southeast Asia, both in population and economic development.
The city serves as the cultural, financial, tourism, political and economic centre of Malaysia. It is also home to the Malaysian parliament (consisting of the Dewan Rakyat and the Dewan Negara) and the Istana Negara, the official residence of the monarch (Yang di-Pertuan Agong). Kuala Lumpur was first developed around 1857 as a town serving the tin mines of the region, and important figures such as Yap Ah Loy and Frank Swettenham were instrumental in the early development of the city during the late 19th century. It served as the capital of Selangor from 1880 until 1978. Kuala Lumpur was the founding capital of the Federation of Malaya and its successor, Malaysia. The city remained the seat of the executive and judicial branches of the Malaysian federal government until these were relocated to Putrajaya in early 1999. However, some sections of the political bodies still remain in Kuala Lumpur. The city is one of the three Federal Territories of Malaysia, enclaved within the state of Selangor, on the central west coast of Peninsular Malaysia.
