Sambor Prei Kuk
The ancient city where monuments of Sambo Prei Kuk are found today, was identified as ISANAPURA, the capital of Chenla in 7th century. Chenla was a former vassal of the Funan kingdom that was one of the first state in Southeast Asia, but it gradually gained its power and eventually King Citrasena Mahendravarman of Funan in the early 7th century.
The main archaeological features in these groups of monuments are said to have been founded by king ISANAVARMAN I, the son of king Citrasena. Many decorative details in Khmer architecture and sculpture are classified as Sambor style: the name was derived from these monuments dated in the first half of the 7th century. Henceforth this kingdom was the leading state and comprised the whole of Cambodia proper. Furthermore, several successions of kings reign might have maintained these monuments as their capital city. The century following the death of JAYAVARMAN I who is the last known king of this kingdom in the second half of the 7th century is a dark period in the history of Chenla. According to a Chinese accounts, in the 8th century, the country of Chenla was divided into land and water Chenlas. The obscurity prevails and this monument might be neglected thereafter.
