Maurya Empire
The Empire was divided into four provinces, with the imperial capital at Pataliputra. From Ashokan edicts, the names of the four provincial capitals are Tosali (in the east), Ujjain (in the west), Suvarnagiri (in the south), and Taxila (in the north). The head of the provincial administration was the Kumara (royal prince), who governed the provinces as king's representative. The kumara was assisted by Mahamatyas and council of ministers. This organizational structure was reflected at the imperial level with the Emperor and his Mantriparishad (Council of Ministers).. The mauryans established a well developed coin minting system. Coins were mostly made of silver and copper. Certain gold coins were in circulation as well. The coins were widely used for trade and commerce
