Tribes in Ancient India c33.57

c33.57

Immediately prior to the rise of Buddhism, there were four powerful monarchies in N. India, each of which was enlarged by the annexation of a neighbouring territory. Thus Aṅga was annexed to Magadha, Kāśī to Kośala, Bharga to Vatsa, and Śūrasena to Avanti. The kingdom of Vatsa must have served as a buffer State between Magadha and Avanti on the one hand, and Kośala and Avanti on the other. Bhāsa in his *Svapnavāsavadattā* tells us that an upstart named Aruṇi ousted Udayana and seized the throne of Vatsa.⁵
