Óc Eo has been regarded as belonging to the historical kingdom of Funan (扶南) that flourished in the Mekong Delta between the 2nd century BC and the 12th century CE. The kingdom of Funan is known to us from the works of ancient Chinese historians, especially writers of dynastic histories, who in turn drew from the testimony of Chinese diplomats and travellers, and of foreign (including Funanese) embassies to the Chinese imperial courts. Indeed, the name "Funan" itself is an artifact of the Chinese histories, and does not appear in the paleographic record of ancient Vietnam or Cambodia. From the Chinese sources, however, it can be determined that a polity called "Funan" by the Chinese was the dominant polity located in the Mekong Delta region. As a result, archeological discoveries in that region that can be dated to the period of Funan have been identified with the historical polity of Funan. The discoveries at Óc Eo and related sites are our primary source for the material culture of Funan.
