It would be useless to follow in detail the long chronicle of the kings of Champa but a few events merit mention. In 446 and again in 605 the Chinese invaded the country and severely chastised the inhabitants. But the second invasion was followed by a period of peace and prosperity. Śambhuvarman (†629) restored the temples of Mi-so'n and two of his successors, both called Vikrântavarman, were also great builders. The kings who reigned from 758 to 859, reckoned as the fifth dynasty, belonged to the south and had their capital at Vîrapura. The change seems to have been important, for the Chinese who had previously called the country Lin-I, henceforth call it Huan-wang. The natives continued to use the name Champa but Satyavarman and the other kings of the dynasty do not mention Mi-so'n though they adorned and endowed Po-nagar and other sanctuaries in the south. It was during this period (A.D. 774 and 787) that the province of Kauthâra was invaded by pirates, described as thin black barbarians and cannibals, and also as the armies of Java[333]. They pillaged the temples but were eventually expelled. They were probably Malays but it is difficult to believe that the Javanese could be seriously accused of cannibalism at this period[334]. The capital continued to be transferred under subsequent dynasties. Under the sixth (860-900) it was at Indrapura in the north: under the seventh (900-986) it returned to the south: under the eighth (989-1044) it was in Vijaya, the central province. These internal changes were accompanied by foreign attacks. The Khmers invaded the southern province in 945. On the north an Annamite Prince founded the kingdom of Dai-côviêt, which became a thorn in the side of Champa. In 982 its armies destroyed Indrapura, and in 1044 they captured Vijaya. In 1069 King Rudravarman was taken prisoner but was released in return for the cession of the three northernmost provinces. Indrapura however was rebuilt and for a time successful wars were waged against Camboja, but though the kings of Champa did not acquiesce in the loss of the northern provinces, and though Harivarman III (1074-80) was temporarily victorious, no real progress was made in the contest with Annam, whither the Chams had to send embassies practically admitting that they were a vassal state. In the next century further disastrous quarrels with Camboja ensued and in 1192 Champa was split into two kingdoms, Vijaya in the north under a Cambojan prince and Panran in the south governed by a Cham prince but under the suzerainty of Camboja. This arrangement was not successful and after much fighting Champa became a Khmer province though a very unruly one from 1203 till 1220. Subsequently the aggressive vigour of the Khmers was tempered by their own wars with Siam. But it was not the fate of Champa to be left in peace. The invasion of Khubilai lasted from 1278 to 1285 and in 1306 the provinces of O and Ly were ceded to Annam.
