Pallava dynasty
It is also possible that Funan was a multicultural society, including various ethnic and linguistic groups. In the late 4th and 5th centuries, Indianization advanced more rapidly, in part through renewed impulses from the south Indian Pallava dynasty and the north Indian Gupta Empire. The only extant local writings from the period of Funan are paleographic Pallava Grantha inscriptions in Sanskrit of the Pallava dynasty, a scholarly language used by learned and ruling elites throughout South and Southeast Asia. These inscriptions give no information about the ethnicity or vernacular tongue of the Funanese.
