The area of Dvaravati (what is now Thailand) was first inhabited by Mon people who had arrived and appeared centuries earlier. The foundations of Buddhism in central Southeast Asia were laid between the 6th and 9th centuries when a Theravada Buddhist culture linked to the Mon people developed in central and northeastern Thailand. Theravadans believe that enlightenment can be obtained only by one living the life of a monk (and not by a layman). Unlike Mahayana Buddhists, who admit the texts of numerous Buddhas and Bodhisattvas into canon, Theravadans venerate only the Buddha Gautama, the founder of the religion. The Mon Buddhist kingdoms that rose in what are now parts of Laos and Central Plain of Thailand were collectively called Dvaravati.
