Mahajanapadas
Mahājanapada (Sanskrit: महाजनपद, Mahājanapada), literally "great realm", (from maha, "great", and janapada "foothold of a tribe", "country") refers to ancient Indian kingdoms that existed between the sixth and third centuries BC. Ancient Buddhist texts like Anguttara Nikaya make frequent reference to sixteen great kingdoms and republics (Solas Mahajanapadas) which had evolved and flourished in a belt stretching from Gandhara in the northwest to Anga in the eastern part of the Indian subcontinent and included parts of the trans-Vindhyan region, prior to the rise of Buddhism in India. The sixth century BC is often regarded as a major turning point in early Indian history.
