Rise of Magadha (Pages 33–37)

Introduction

Among the sixteen Mahajanapadas, Magadha emerged as the most powerful kingdom and eventually became the centre of the first large empire in Indian history. Historians believe that Magadha’s rise was not accidental but the result of several geographical, economic, political and military advantages.

The kingdom gradually expanded under rulers such as Bimbisara, Ajatasattu and the Nanda dynasty, laying the foundation for the Mauryan Empire.
