The provinces of Siem-reap and Battambang, in which Angkor Thom and the principal ancient monuments are situated, were annexed by Siam at the end of the eighteenth century, but in virtue of an arrangement negotiated by the French Government they were restored to Camboja in 1907, Krat and certain territories being at the same time ceded to Siam[270]. 3 The religious history of Camboja may be divided into two periods, exclusive of the possible existence there of Hinayanist Buddhism in the early centuries of our era. In the first period, which witnessed the construction of the great monuments and the reigns of the great kings, both Brahmanism and Mahayanist Buddhism nourished, but as in Java and Champa without mutual hostility. This period extends certainly from the sixth to the thirteenth centuries and perhaps its limits should be stretched to 400-1400 A.D. In any case it passed without abrupt transition into the second period in which, under Siamese influence, Hinayanist Buddhism supplanted the older faiths, although the ceremonies of the Cambojan court still preserve a good deal of Brahmanic ritual. During the first period, Brahmanism and Mahayanism were professed by the Court and nobility. The multitude of great temples and opulent endowments, the knowledge of Sanskrit literature and the use of Indian names, leave no doubt about this, but it is highly probable that the mass of the people had their own humbler forms of worship. Still there is no record of anything that can be called Khmer--as opposed to Indian--religion. As in Siam, the veneration of nature spirits is universal in Camboja and little shrines elevated on poles are erected in their honour in the neighbourhood of almost every house. Possibly the more important of these spirits were identified in early times with Indian deities or received Sanskrit names. Thus we hear of a pious foundation in honour of Brahmarakshas[271], perhaps a local mountain spirit. Śiva is adored under the name of Śrî Śikhareśvara, the Lord of the Peak and Krishṇa appears to be identified with a local god called Śrî Champeśvara who was worshipped by Jayavarman VI[272].
