Mon language
These kingdoms adopted Indian culture together with Theravada Buddhism and grew up under post-Indian (the local technology that adapt from Indian) and Mon influence in the 11th to 12th centuries, as it entered into the historical era. This first period under the influence of Indian culture was called the Dvaravati period. For the time being this kingdom was known as Saruka Lavo (Mon language). Although the inscription stones found in this area are the Mon language, however there is not clear evidence to prove if the population of Lavo were actually of Mon ethnicity.
