::''This article should not be confused with the '
Federated Malay States'''.

'Malaya in 1922'.
The Unfederated Malay States are coloured in blue, the FMS in yellow and British Straits Settlements in red.
The 'Unfederated Malay States' were five
Malay states, namely:
★
Johor
★
Kedah
★
Kelantan
★
Perlis
★
Terengganu
Together the states were not a single entity but merely a category to describe those states which were not the
Federated Malay States or the
Straits Settlements.
History
Under the
Bangkok Treaty of 1909, Siam (as Thailand was once known) transferred whatever rights or power over the northern
Malay states (
Kelantan,
Terengganu,
Kedah and
Perlis) to the
United Kingdom. The British later imposed treaties similar to the
Federated Malay States towards these northern states.
Johore accepted a treaty of protection in 1885 and eventually succumbed under pressure to accept a British Advisor in 1904.
The five states later joined with the other states to form the
Malayan Union, and are now part of
Malaysia.
Administration and language
The chief officer of the
British colonial administration was called the "advisor". In contrast to the Federated Malay States, the Unfederated Malay States enjoyed greater autonomy. The ''de facto'' official language of the Unfederated Malay States was
Malay with
Jawi script.
