Origins & Early Life

The Anglo-Siamese Treaty of 1909, also known as the Bangkok Treaty of 1909, was an agreement between the United Kingdom and the Kingdom of Siam (now Thailand). It was signed on 10 March 1909 in Bangkok, with ratifications exchanged in London on 9 July 1909. The treaty established the modern border between Malaysia and Thailand.

Career & Major Achievements

Areas around modern Pattani, Narathiwat, southern Songkhla, Satun and Yala remained under Thai control, later becoming the site of the South Thailand insurgency. Under the treaty, Thailand relinquished claims to Kedah (Thai: ไทรบุรี, romanized: Saiburi), Kelantan (กลันตัน, Kalantan), Perlis (ปะลิส, Palit) and Terengganu (ตรังกานู, Trangkanu), which entered the British sphere of influence as protectorates. During World War II, Thailand briefly reclaimed these territories with Japanese permission, but they were returned to British control after the defeat of the Axis powers.

Enduring Legacy & Impact

These four states, together with Johor, later became known as the Unfederated Malay States, eventually joining the Federation of Malaya and forming part of present-day Malaysia. The Kingdom of Siam was controlled by the monarch.
