In the poem of the great war once waged by the kings of the Aryas on the Yamuna and the upper Ganges the Tritsus are no longer found on the Sarasvati or the Yamuna. The enemies at this period are the Matsyas and the Bharatas, the former on the Yamuna, the latter further to the east on the upper Ganges. The Tritsus have been forced further to the east, and have become lost among the Koçalas, who are situated on the Sarayu, or have taken that name; at any rate, the name of Sudas appears in the genealogical table of the rulers of the Koçalas, and in the Ramayana, as in other traditions, Vasishtha, who (or whose family) then gained victory by his prayers for Sudas, is the wisest priest among the Koçalas.[136] Hence we may conclude that at a later time the Bharatas were more fortunate in their advance to the east. The struggle for their country and throne is the central point in the poem. According to the Mahabharata the rulers of the Bharatas spring from Manu. With Ila, the daughter of Manu, Budha the son of the moon, begot the 'pious' Pururavas, _i.e._ the far-famed. Pururavas is succeeded by Ayus, Nahusha, and Yayati. From Yayati's elder sons, Anu, Druhyu, Yadu, spring the Anus, the Drahyus, and the Yadavas,[137] of whom we already have the two first as confederates of the Bharatas.[138] Yayati was followed on the throne by his youngest son Puru. Dushyanta, one of the successors of Puru, married Çakuntala, the daughter of the priest Viçvamitra. To him she bore Bharata, who reduced all nations, and was lord of the whole earth. After Bharata, Bhumanyu, Suhotra, Ajamidha, and Samvarana, occupied the throne of Hastinapura, the chief city of the kingdom on the upper Ganges.[139] In Samvarana's reign the kingdom was attacked by droughts, famine, and pestilence; and the king of the Panchalas advanced with a mighty host, and conquered Samvarana in the battle, who fled with his wife Tapati, his children and dependants, to the west, and took up his abode in a forest hut in the neighbourhood of the Indus. There the Bharatas lived for a long time, protected by the impenetrable country. Afterwards Samvarana reconquered the glorious city which he had previously inhabited, and Tapati bore him Kuru, whom the nation chose to be king. Kuru was succeeded on the throne of Hastinapura by Viduratha, Anaçvan, Parikshit, Pratiçravas, Pratipa and Çantanu.
