Hindu influences reached the Indonesian Archipelago as early as the first century. At this time, India started to strongly influence Southeast Asian countries. Trade routes linked India with southern Burma, central and southern Siam, lower Cambodia and southern Vietnam and numerous urbanised coastal settlements were established there.

For more than a thousand years, Indian Hindu/Buddhist influence was, therefore, the major factor that brought a certain level of cultural unity to the various countries of the region. The Pali and Sanskrit languages and the Indian script, together with Theravada and Mahayana Buddhism, Brahmanism and Hinduism, were transmitted from direct contact as well as through sacred texts and Indian literature, such as the Ramayana and the Mahabharata epics.
