Kuala Lumpur is the cultural, financial and economic centre of Malaysia. It is also home to the Parliament of Malaysia and the official residence of the Yang di-Pertuan Agong, the Istana Negara. Kuala Lumpur first developed around 1857 as a town serving the tin mines of the region and 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 and 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.
