The sixteen Mahajanapadas were prominent ancient kingdoms or oligarchic republics that existed in northern India during the sixth century B.C. The list of these sixteen Mahajanapadas is found in the Bhagvati Sutra, which is an important Jain text. The Bhagvati Sutra is also known as the Vyākhyāprajñapti. It is one of the most comprehensive texts in Jainism and is part of the Jain Agamas, which are canonical scriptures that form the foundation of Jain religious literature.
The Bhagvati Sutra is a detailed text that includes dialogues between Mahavira, the 24th Tirthankara of Jainism, and his disciples. It covers a wide range of topics, including philosophy, cosmology, ethics, and the organization of society, which includes references to the political entities of the time, such as the Mahajanapadas. The text serves as a significant historical source, providing insights into the socio-political conditions of ancient India, particularly from a Jain perspective.
