the reconsecrated maharajadhiraja (king of kings) of Mount Phu Kao where "the people that lived in the region along with the people who came with Devanika, became the forerunners of the prosperous Khmer people". Water and Land Chenla The Táng histories say that after the end of the reign period shénlóng (神龍) (i. e. after 6 February 707) Zhēnlà came to be divided in two realms, Lùzhēnlà (陸真臘) ("Land Chenla", also called Wèndān (文單) or Pólòu (婆鏤)) and Shuīzhēnlà (水真臘) ("Water Chenla") [47] and returned to the anarchic state that had existed before it was unified under the kings of Fúnán and the first kings of Chenla. On the other hand, Water Chenla was associated with the Mekong Delta and had access to the river and its benefits, but this advantage had its downfalls as it made Water Chenla more susceptible to attacks. Late in the eighth century AD, it faced war from Javanese pirates that ultimately took over the Mekong Delta and then later the whole Chenla Empire ("Cambodia-History"). However author Michael Vickery asserts that these categories of Water and Land Chenla created by the Chinese are misleading and meaningless because the best evidence shows that until 802 AD, there was no single, great state in the land of ancient Cambodia, but a number of smaller ones. Decline of Chenla The number of inscriptions declined sharply during the eighth century. However, some theorists, who have examined the Chinese transcripts, claim that Chenla started falling during the 700s as a result of both internal divisions and external attacks by the Shailendra dynasty of Java, who eventually took over and joined under the Angkor kingdom of Jayavarman II. According to the Sdok Kak Thom inscription (1053), Jayavarman II and his son Indrayudha defeated a Cham army in 790, then moved to north of the Tonle Sap, established the city of Hariharalaya, 15 kilometers south of Angkor. Individually, historians reject a classical decline scenario, arguing there was no Chenla to begin with, rather a geographic region had been subject to prolonged periods of contested rule, with turbulent successions and an obvious incapability to establish a lasting centre of gravity. Historiography ends this era of nameless upheaval only in the year 802, when Jayavarman II established the appropriately named Khmer Empire. Society Capital According to George Cœdès, Champasak was the origin of the ruling dynasty of Chenla and Vat Phou its spiritual center.
