The most important part, if not the whole, of the Indian Aryans is meant by the "five tribes," an expression of frequent occurrence in the Rigveda. It is not improbable that by this term were meant five tribes which are enumerated together in two passages, the Purus, Turvaças, Yadus, Anus, and Druhyus. These are often mentioned as engaged in intertribal conflicts. Four of them, along with some other clans, are named as having formed a coalition under ten kings against Sudas, chief of the Tritsus. The opposing forces met on the banks of the Parushni, where the great "battle of the ten kings" was fought. The coalition, in their endeavours to cross the stream and to deflect its course, were repulsed with heavy loss by the Tritsus. The Purus are described as living on both banks of the Sarasvati. A part of them must, however, have remained behind farther west, as they were found on the Parushni in Alexander's time. The Rigveda often mentions their king, Trasadasyu, son of Purukutsa, and speaks of his descendant Trikshi as a powerful prince. The Turvaças are one of the most frequently named of the tribes. With them are generally associated the Yadus, among whom the priestly family of the Kanvas seems to have lived. It is to be inferred from one passage of the Rigveda that the Anus were settled on the Parushni, and the priestly family of the Bhrigus, it would appear, belonged to them. Their relations to the Druhyus seem to have been particularly close. The Matsyas, mentioned only in one passage of the Rigveda, were also foes of the Tritsus. In the Mahabharata we find them located on the western bank of the Yamuna. A more important name among the enemies of Sudas is that of the Bharatas. One hymn (iii. 33) describes them as coming to the rivers Vipaç and Çutudri accompanied by Viçvamitra, who, as we learn from another hymn (iii. 53), had formerly been the chief priest of Sudas, and who now made the waters fordable for the Bharatas by his prayers. This is probably the occasion on which, according to another hymn (vii. 33), the Bharatas were defeated by Sudas and his Tritsus, who were aided by the invocations of Vasishtha, the successor and rival of Viçvamitra. The Bharatas appear to be specially connected with sacrificial rites in the Rigveda; for Agni receives the epithet Bharata, "belonging to the Bharatas," and the ritual goddess Bharati, frequently associated with Sarasvati, derives her name from them. In a hymn to Agni (iii. 23), mention is made of two Bharatas named Devaçravas and Devavata who kindled the sacred fire on the Drishadvati, the Apaya, and the Sarasvati, the very region which is later celebrated as the holy land of Brahmanism under the names of Brahmavarta and Kurukshetra. The family of the Kuçikas, to whom Viçvamitra belonged, was closely connected with the Bharatas.
