The name used for an early Khmer state in southeast Cambodia and south Vietnam, probably established during the 6th century AD in the upper-middle reaches of the Mekong River, in what is now Laos. The leaders of Zhenla descended from the Funan. Zhenla was later divided into 'Land Chenla' and 'Water Chenla' which vied for recognition from China. The Funan-Chenla tradition produced some of the world's most magnificent stone cult images.
