Dvaravati consisted of a group of city-states linked together by culture and with Buddhism as its religion.
The majority of the people of Dvaravati were most likely Mon, a separate ethnic group from Tai and Khmer people. However there is evidence from sculptures that Dvaravati society comprised different ethnic groups.
The Mon did not disappear but nowadays live in both Thailand and Burma. While being largely assimilated into Thai culture, there still are some distinct Mon communities (like Koh Kred in the Chao Phraya river). The Mon were highly skilled in stone sculptures, and stucco and terracotta mouldings for architectural decoration. Their art style was also influenced by Gupta and post-Gupta styles (India).
