Bernia agreement

The Berne Accords are agreements signed between Siam and Great Britain in 1826 .

The agreement was named after the main emissary from the East India Company, Henry Burney. The agreement recognized the Siamese claim over the four northern Malay sultanates of Kedah, Kelantan, Perlis, and Terengganu. The agreement further guaranteed Penang's British property and their right to trade in Kelantan and Terenggan without Siamese intervention. Four Malay Sultanates were not represented in the negotiation of agreements.

In 1909, the parties to the agreement signed a new agreement that replaced the 1826 agreement. In 1909, the agreement, known as the Anglo-Siamese Agreement of 1909 , transferred the four Malay Sultanates to British dominion .
