The Mauryan Empire: Polity, Administration, Economy and Culture (322–185 BCE) — Part 2: 2. Extent and Political Geography

2. Extent and Political Geography

At its greatest extent under Ashoka, the Mauryan Empire covered most of the Indian subcontinent, excepting only the far south (kingdoms of Cholas, Pandyas, Keralaputras, and Satiyaputras, which are mentioned in Asokan inscriptions as independent but friendly states). The empire encompassed:

• Northwest: Afghanistan (Kandahar, where bilingual Greek-Aramaic edicts were found) and Baluchistan
• North: Taxila (modern Pakistan) in Gandhara
• East: Coastal Odisha (Kalinga, conquered by Ashoka)
• Deccan: Suvarnagiri in Karnataka
• West: Ujjayini (Ujjain) and Sopara on the western coast

The Mauryan Empire was the first in Indian history to bring such a vast, diverse territory under a single political authority. Its capital Pataliputra, located on the Ganga, commanded critical trade and communication routes. Contemporary Greek accounts describe Pataliputra as a magnificent city with wooden ramparts and watchtowers, palaces and public buildings, lively streets, and busy markets where merchants from distant lands traded silk from China, spices and gems from the south, and fine textiles from different regions.

3. Administration

3.1 Central Administration

The Mauryan state was a monarchy where supreme authority rested with the king. However, the Arthashastra is emphatic that the king did not and could not rule alone: as Kautilya states, 'One wheel does not move the carriage.' Central to the system was the Council of Ministers (mantri-parishad), a body of senior statesmen that advised the king. Key ministers included the treasurer, the chief tax collector, the chief legal advisor, and the commander-in-chief of the army. An Asokan inscription records that in exceptional circumstances—such as the emperor's absence—the council could take decisions independently in the public interest.

Kautilya identifies the seven constituents of the state (Saptanga): the king (swami), councillors and ministers (amatya), the territory with its population (janapada), fortified towns and cities (durga), the treasury (kosha), the forces of law and order (danda), and the allies (mitra). Together, these seven constituents formed the organic whole of the Mauryan state. The Arthashastra states that these constituents must remain properly integrated for the state to function effectively.

The military was organised with considerable sophistication. According to Megasthenes, a committee with six subcommittees coordinated military activity: one for the navy, a second for transport and provisions (including bullock carts, food, fodder, and recruitment of artisans), a third for foot-soldiers, a fourth for horses, a fifth for chariots, and a sixth for elephants. Greek sources credit the Mauryan ruler with a standing army of 600,000 foot-soldiers, 30,000 cavalry, and 9,000 elephants, though some historians consider these figures exaggerated.

3.2 Provincial Administration

The empire was too geographically and culturally diverse for uniform central administration. There were five major political centres: the capital Pataliputra and the provincial centres of Taxila, Ujjayini, Tosali, and Suvarnagiri, all mentioned in Asokan inscriptions. Administrative control was strongest around the capital and provincial centres, which were strategically chosen: Taxila and Ujjayini lay on important long-distance trade routes, while Suvarnagiri (literally, 'the golden mountain') was positioned to tap the gold mines of Karnataka.

Provincial governors—generally princes of the royal family—administered the provinces. Below them were district governors (pradeshikas) responsible for judicial and administrative functions. The village, governed by a village headman (gramika), was the lowest administrative unit. Megasthenes describes senior officials who supervised rivers, measured land, regulated irrigation channels, collected taxes, and supervised occupational groups such as woodcutters, carpenters, blacksmiths, and miners.

Communication across this vast territory was maintained through a network of roads (including the Uttarapatha, connecting the northwest with the Ganga plains), couriers carrying messages from place to place, and rest houses and wells established at regular intervals along major roads.

3.3 The Arthashastra as a Source

The Arthashastra, attributed to Kautilya, is the single most important textual source for understanding Mauryan governance. It is a systematic treatise on statecraft covering defence, economics, administration, justice, urban planning, agriculture, trade, weights and measures, and public welfare. Its detailed coverage extends even to administrative minutiae—for example, it describes exactly how elephant forests should be guarded and wild elephants captured for the army.

Kautilya's central philosophy of governance holds that the king's welfare is inseparable from the welfare of his subjects: 'In the happiness of his subjects lies the king's happiness; in their welfare his welfare. He shall not consider as good only that which pleases him but treat as beneficial to him whatever pleases his subjects.' The Arthashastra also emphasises that 'Only if a king is himself energetically active do his officers follow him energetically.'

The Arthashastra must be used critically as a historical source: it is partly prescriptive (what ought to be done) rather than purely descriptive. Used alongside Asokan inscriptions, the account of Megasthenes, and Buddhist, Jaina, and Puranic literature, it provides a remarkably detailed picture of the Mauryan state.
