What happened
The earliest known Khmer-speaking state, Funan, grew up around the Mekong Delta and the port city of Oc Eo, in what is now southern Vietnam. UNESCO's nomination file for the Oc Eo-Ba The archaeological site describes it as the main transshipment point between the Indian Ocean and the Pacific through the Kra Strait, part of the first world trading system connecting China, Southeast Asia, India, the Persian Gulf, and the Mediterranean. Archaeologists working the site since French excavations began in the 1940s have recovered Roman gold coins and medals, Han dynasty bronze mirrors, Persian lamps, and glass and precious metals imported from India, alongside local jewelry and glass workshops. The finds show a town that manufactured goods for export across South Thailand, Malaysia, Java, and southern China as much as it traded.
Why it matters
Funan's wealth came from controlling a chokepoint on the sea route between India and China, and that same route carried Indian religious and political ideas into the Mekong basin. Every later Khmer institution the empire is remembered for, the god-king, the Sanskrit inscriptions, the Hindu temple architecture, arrives on the same ships that carried the glass beads and Roman coins found at Oc Eo.
How we know
The physical evidence comes from stratified excavation layers at Oc Eo-Ba The, first mapped by French archaeologist Louis Malleret in 1944 using aerial photography, and re-excavated in multiple campaigns through the early 2000s. Funan's political history is reconstructed mostly from Chinese dynastic records, since no royal Funanese chronicle survives.
