The sultan of Kedah made unsuccessful attempts to regain his territory until, in 1842, he agreed to Siamese terms. The Siamese withdrew their military forces from Kedah and Sultan Ahmad Tajuddin Halim Syah was reinstated to the Kedah ruling house.
The price Kedah paid was that the part of the state bordering Siam was sliced off to create the state of Perlis. Perlis then became a separate vassal principality state under a governor, Syed Hussain Jamalulail.
On 20 May 1843, the Siamese made Syed Hussain Jamalulail, maternal grandson of the Sultan of Kedah, became the first Raja of Perlis and he was obligated to send the triennial Bunga Emas to Bangkok as acknowledgement of Siam’s suzerainty.
The Siamese reinstalled the sultan but made Perlis into separate vassal principality with its own raja.
The British exerted pressure on Siam and in 1909, by the Treaty of Bangkok, the Siamese ceded their Malay dependencies (Perlis, Kedah and Terengganu). A British Resident later was installed at Arau.
