The High Commissioner's official residence was King's House (now part of a hotel, Carcosa Seri Negara), located inside the Perdana Lake Gardens in Kuala Lumpur, the capital of the Federated Malay States.
The rest of the Straits Settlements (i.e. Penang and Malacca) were merged with the Federated Malay States, Perlis, Kedah, Kelantan, Terengganu, and Johore to form the Malayan Union, another Crown colony.
The native rulers in the Federated Malay States, Perlis, Kedah, Kelantan, Trengganu, and Johore ceded their power to the United Kingdom, thus turning these territories into British colonies.
In 1948, the British government returned power to the native rulers of the former protected states, and the Malayan Union was transformed into the Federation of Malaya – a federation of protected states and Crown colonies (Penang and Malacca had remained Crown colonies throughout the Malayan Union era).
The title 'High Commissioner' became that of the senior British diplomat in the independent Malaya (and later in Malaysia), as is normal in Commonwealth countries.
