扶南
The Kingdom of Funan is considered to be the mother of all later Southeast Asian kingdoms. During the Funan period (1st century - sixth century CE) the Khmer also acquired Buddhism, the concept of the Shaiva imperial cult of the devaraja and the great temple as a symbolic world mountain. The rival Khmer Chenla Kingdom emerged in the fifth century and later conquered the Kingdom of Funan. Chenla was an upland state whose economy was reliant on agriculture whereas Funan was a lowland state with an economy dependent on maritime trade.
