We can do no more than make hypotheses about the original contents of the poem on the great war. Against the Kurus, who, at the head of the Bharatas, maintained their supremacy on the upper course of the Yamuna and the Ganges, there rises in rebellion a younger race, the Pandus, who have risen into note among the Panchalas. The sons of Pandu receive in marriage the daughter of the king of the Panchalas, who are situated to the south of the Bharatas on the confluence of the Yamuna and the Ganges; and they are aided by the king of the Matsyas. It is Krishna, a hero of the Yadavas, to whom the Pandus owe their success in council and action. The Epos represents the Pandus as growing up in their childhood in the forest, and afterwards again making their home in the wilderness; they receive half of the kingdom of the Bharatas, and then lose it; and in their half they found Indraprastha to the west of Hastinapura on the Yamuna. From this we may conclude that the supremacy of the Bharatas established by the Kurus was resisted by the Panchalas and Matsyas and a part of the Yadavas--the Yadavas fight in the Epos partly for the Kurus and partly against them--and that a family among these nations, apparently a family of the Panchalas, succeeded in combining this resistance and establishing another kingdom, with Indraprastha as a centre, beside the kingdom of Hastinapura, from which they finally conquered the Bharatas. This struggle of the Panchalas and Matsyas against the Bharatas is the nucleus of the Epos. A tradition may lie at the base of the statement in the poems, that the nations of the East, the Madras, Koçalas, Videhas and Angas (in north-western Bengal), fight beside the Kurus against the Panchalas and Matsyas: at any rate it would be to the interest of the previous settlers on the Ganges to repel the advance of later immigrants. On the other hand, the Kaçis, in the region of the later Benares, may have fought against the Bharatas. However this may be, the race of the Kurus disappeared in a great war, and kings of the race of Pandu ascended the throne of Hastinapura. If, as we have assumed, the Bharatas had previously forced the Tritsus from the Sarasvati to the Yamuna, and from the Yamuna to the upper Ganges, and from the upper Ganges further east to the Sarayu, they were now, in turn, not indeed expelled, but over-mastered, by the tribes which had followed them and settled on the Yamuna. The metropolis of the kingdom which arose out of these struggles was Hastinapura, the chief city of the Bharatas; under the rule of the race of Pandu it comprised the Bharatas and the Panchalas; in the old ritual of consecration we find the formula: "This is your king, ye Kurus, ye Panchalas."[143]
