Analysis of information sources in references of the Wikipedia article "Patani Kingdom" in English language version.
One could also mention the tradition recorded in the Sejarah Melayu, namely of a conquest of Kota Mahligai by a Siamese prince called Chau Sri Bangsa, his conversion to Islam, the foundation of a new settlement on the coast which was named Pattani, and the sending of a "drum of sovereignty" by Sultan Mahmud Shah of Malacca. Having been installed to the beat of the drum, Chau Sri Bangsa took the title of Sri Sultan Ahmad Shah (Brown 1952, 152). This reference to Sultan Mahmud Shah of Malacca would place us in the period 1488-1511.
