Chandragupta Maurya was a king who united much of northern and central India in the late 4th century BCE. He defeated the powerful Nanda Empire and established the Maurya Empire. Chandragupta waged successful military campaigns against several neighboring rulers, expanding his empire. He administered the large empire efficiently using a central bureaucracy divided into administrative units at the city and regional levels. Chandragupta adopted Jainism late in life and passed away by fasting at Shravanabelagola in Karnataka.
