Explanation: Apart from Magadha with its capital at Pataliputra, the Mauryan Empire was divided into four other provinces, with capitals at Taxila (north-western India), Suvarnagiri (southern India), Tosali (eastern India), and Ujjain (western India). During Ashoka’s reign, a fifth province of Kalinga was added.

• The head of the provincial administration was viceroy, who was in charge of law and order, and collection of taxes for the centre.
• He was generally a prince from the royal family (kumara or aryaputra) and was assisted by Mahamattas and a council of ministers.
• Besides imperial provinces, there were a number of territories that enjoyed some measure of autonomy.
