British High Commissioner in Malaya

In 1896, the post High Commissioner for the Federated Malay States was created; the High Commissioner represented the British Government in the Federated Malay States, a federation of four British protected states in Malaya. 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, then the capital of the Federated Malay States. King's House served as an important place for royal dignitaries and distinguished guests.

The Governor of the Straits Settlements had always been ex-officio the High Commissioner for the Federated Malay States; the Governor's official residence was in Singapore, the capital of the Straits Settlements, and was known as Government House (now Istana, the official residence of the President of Singapore).

In each of the five protected states of Perlis, Kedah, Kelantan, Trengganu, and Johore (usually collectively referred to as the 'Unfederated Malay States'), the British government is represented by an Adviser: the Adviser to the Government of Perlis; the Adviser to the Sultan of Kedah; the Adviser to the Government of Kelantan; the Adviser, Trengganu; and the General Adviser to the Government of Johore.

The Straits Settlements was dissolved in 1946. Singapore became a Crown colony in her own right. The rest of the Straits Settlements (i. e. Penang and Malacca) was merged with the Federated Malay States, Perlis, Kedah, Kelantan, Trengganu, 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. The new Crown colony of the Malayan Union was headed by a Governor – the Governor of the Malayan Union.
