Kingdom of Funan
The Khmer are considered a part of Greater India, owing to them adopting Indian culture, traditions and religious identities. The first powerful trading kingdom in Southeast Asia, the Kingdom of Funan, was established in southeastern Cambodia and the Mekong Delta in the first century, although extensive archaeological work in Angkor Borei District near the modern Vietnamese border has unearthed brickworks, canals, cemeteries and graves dating to the fifth century BCE.
