Once the Indian Ocean Trade route was well-established (became popular), several kingdoms became very rich. These cities were located on the coast (near the ocean) and were used by foreigners to trade their goods and for travelers to rest while on long journeys across the ocean. The first of these kingdoms in Southeast Asia was located in present day southern Vietnam, Cambodia, and Thailand. It was called Funan.

Historians first learned about from written records from China. The Chinese were Funan’s biggest trading partner and ally (friend). Archeologists later found physical evidence of architecture and artifacts to confirm the existence of this kingdom.

Funan may have existed since 1 AD, but it became more powerful and important once the Indian Ocean Trade route was underway. Several port cities in Funan became important places for trade. Perhaps the most important city, in regards to trade anyway, with Oc-Eo in modern day Vietnam. Oc-Eo, however, was not the political capital of Funan. The capital city was a called Vyadhapura. Historians are not sure where this city was located.
