Mauryan empire

(c. 321–c. 185 BC) In ancient India, a state centred at Pataliputra (later Patna) near the junction of the Son and Ganges (Ganga) rivers. After the death of Alexander the Great, Chandragupta Maurya (Candra Gupta), the dynastic founder, carved out an empire that encompassed most of the subcontinent except for the Tamil south. Ashoka (r. c. 269–232 BC), the famous Buddhist emperor, left stone edicts that include some of the oldest deciphered original texts of India. The empire declined after Ashoka's death, but in its heyday it was an efficient and highly organized autocracy. See also Gupta dynasty; Nanda dynasty.
