The period of the Mahajanapadas (c. 600 BCE – 342 BCE) marks a significant turning point in Indian history, known as the "Second Urbanization." This era saw the shift of the political center from the North-West to the Gangetic plains and the emergence of large territorial states.
By the 6th century BCE, the development of iron tools allowed for the clearing of dense forests in the Ganges Valley, leading to agricultural expansion, surplus production, and the rise of towns and urban centres.
Literary Sources: The primary information comes from the Anguttara Nikaya (Buddhist text) and the Bhagavati Sutra (Jaina text), both of which list 16 "Great Kingdoms" or Mahajanapadas.

Monarchies (Rajyas): Ruled by a king with centralized authority (e.g., Magadha, Vatsa).
