Note: The Mon kingdom of Dvaravati existed between the 3rd and 11th century AD and its territory extended from present-day Thailand's central Chaopya basin in the south up to Lumpun on the north and from across the lower part of Burma towards the east to the Bay of Bengal to the west. It was the first Mon kingdom established in what is now Thailand and played an important role in spreading Indic culture in the region. Situated in the lower Chao Phraya River valley, Dvaravati was prevented by geographic barriers from establishing close political ties with other Mon states to the west in southern Myanmar (Burma) and northern Thailand.
