Indigenous Beliefs in Southeast Asia
Muslims can be found in all mainland countries, but the most significant populations are in southern Thailand and western Burma (Arakan). The Cham people of central Vietnam and Cambodia are also Muslim.
Not only were the Vietnamese becoming increasingly sinicized, but the Cham, who had once had an important indianized culture in southern Vietnam, turned from this tradition and embraced Islam, a religion that was becoming established among other Austronesian-speaking peoples in major societies of the Indonesian archipelago and on the Malay Peninsula.
But, it is also vividly seen the extent of Indianization in Southeast Asia because, although Indianization process ceased to move forward after 13th century, the legacy it left behind still had profound effect in social, religious, architecture patterns of southeast Asia embedding in its own features of culture trademark.
