The Janapadas (pronounced [dʑɐnɐpɐdɐ]) (c. 1500–600 BCE) were the realms, republics (ganapada) and kingdoms (saamarajya) of the Vedic period on the Indian subcontinent. The Vedic period reaches from the late Bronze Age into the Iron Age: from about 1500 BCE to the 6th century BCE. With the rise of sixteen Mahajanapadas ("great janapadas"), most of the states were annexed by more powerful neighbours, although some remained independent.
