What is difference mahajanapadas and janapadas?

Janapadas were ancient kingdoms or territories in India, primarily during the Vedic period, representing the early stages of political organization. Mahajanapadas, which emerged later, were more advanced and larger political entities that formed around the 6th century BCE, often comprising several janapadas. The mahajanapadas were characterized by greater political complexity, urbanization, and economic development, and they played a significant role in the rise of early Indian states.
