The Janapadas were the major kingdoms of Vedic India. During that period, Aryans were the most powerful tribes and were called ‘Janas’. This gave rise to the term Janapada where Jana means ‘people’ and Pada means ‘foot’.

By the 6th century BCE, there were approximately 22 different Janapadas. Socio-economic developments chiefly due to the use of iron tools in agriculture and military, along with religious and political developments led to the rise of the Mahajanapadas from small kingdoms or Janapadas.
