Administration
The Empire was divided into four provinces, which one of the four, look like a giant crescents. 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).
Historians theorize that the organization of the Empire was in line with the extensive bureaucracy described by Kautilya in the Arthashastra: a sophisticated civil service governed everything from municipal hygiene to international trade. The expansion and defense of the empire was made possible by what appears to have been the largest standing army of its time. According to Megasthenes, the empire wielded a military of 600,000 infantry, 30,000 cavalry, and 9,000 war elephants. A vast espionage system collected intelligence for both internal and external security purposes. Having renounced offensive warfare and expansionism, Ashoka nevertheless continued to maintain this large army, to protect the Empire and instill stability and peace across West and South Asia.
