Here the origin of these two tribes were attributed to a king in the race of Puru, known by the name of Vyushitaswa. His wife was Bhadra, the daughter of Kakshivat (Kakshivat was the son of Gautama-Dirghatamas, begotten upon the servant-maid of the queen of a king named Vali who ruled in the outskirts of Magadha. (See also Anga and Magadha). Seven sons were born to Bhadra, after the death of Vyushitaswa. Later they all became kings. Three of them became the three kings of Salwa and four of them became the four kings of Madra.
