A question may, here, be raised : From where did these Indian artists come ? Did they hail from the north or south of India ? It is not possible, on the whole, to restrict the limit in such a way. Like the bulk of the colonists, they might have hailed from all parts of India. Each band of colonists might have counted among its number men from different parts of India. The majority of artists might have come from the South of India, because the style of architecture found prevalent in Kamboja deia is Dravidian. We have already spoken of the two routes which were used by the Indian colonists in coming over to Indo-China. It was possible for the artists from South India to cross over the sea in coming to the coast of Indo-China. Indians, coming as the inheritors of an ancient civilisation, established a powerful kingdom under the name of Camboja. The kingdom of Camboja flourish- ed until the period when the followers of Islam began to impose their religion on the people of Asia. Though, Islam penetrated into India and made in- roads on the islands of the Indian archipelago, yet it could not make any successful movement towards Indo-China* This period, however, should be regarded as "the commencement of the decadence of the great Indo-Chinese civilisation/' With the gradual fall of the kingdom of Camboja, Siam raised up its head. The Thai's became powerful by this time and asserted their independence in the thirteenth century. On the ruins of the Indian colony of Camboja, rose up another Indian colony, namely, the kingdom of SyUma deia.
