Central Administration
The Arthashastra's vision of kingship was rigorous: the king's daily schedule was divided into 16 segments of approximately 90 minutes each, balancing military inspection, public audiences, financial review, council meetings, and personal study. The ideal Arthashastra king was not a passive ruler but an active executive who personally supervised all branches of government.
The central council (Mantri-Parishad) consisted of the Purohita (chief priest), Yuvaraja (crown prince/viceroy), Senapati (commander-in-chief), and Amatyas (senior ministers). These were not merely ceremonial posts — the Arthashastra devotes entire adhikaranas to how the king should test his ministers for loyalty using elaborate sting operations.
The Four Provincial Capitals
| Province / Capital | Region | Viceroy (known) |
|---|---|---|
| Taxila | Northwest (modern KP, Pakistan) | Ashoka (before accession) |
| Ujjain | Western India (Malwa/Avanti) | Ashoka; later Kunala |
| Suvarnagiri | Southern Deccan (Karnataka) | Ashoka (Suvarnagiri edict) |
| Tosali / Dhauli | Eastern Kalinga (Odisha) | Royal prince after 261 BCE conquest |
Each province was governed by a kumara (prince of royal blood) as viceroy, assisted by a mahamatra staff. This ensured loyalty at the top but also created succession vulnerabilities — provincial governors who were princes might themselves be contenders for the throne.
The Administrative Hierarchy
Below the provincial level, the Maurya empire operated a detailed territorial hierarchy:
| Level | Unit | Approximate Size / Officer |
|---|---|---|
| Ahara / Vishaya | District | Rajuka (district head, appointed by 13th regnal year per RE V) |
| Sangrahana | Group of ~800 villages | Sthanika |
| Dronamukha | ~400 villages | — |
| Kharvatika | ~200 villages | — |
| Sthaniya | ~10 villages | — |
| Grama | Village | Gramika (village headman) |
The Adhyakshas — 24+ Departmental Superintendents
One of the Arthashastra's most remarkable features is its detailed description of over 24 departmental heads (Adhyakshas), each responsible for a specific economic or administrative function. UPSC favours the unusual ones:
| Adhyaksha | Responsibility |
|---|---|
| Sitadhyaksha | Superintendent of Agriculture (crown lands) |
| Sunadhyaksha | Superintendent of Slaughterhouses |
| Ganikaadhyaksha | Superintendent of Courtesans (prostitution was regulated, taxed) |
| Panyadhyaksha | Superintendent of Commerce (trade) |
| Akaradhyaksha | Superintendent of Mines |
| Sulkadhyaksha | Superintendent of Tolls and Customs |
| Navadhyaksha | Superintendent of Ships / Navy |
| Lavanadhyaksha | Superintendent of Salt (state monopoly) |
The sheer granularity of these offices — including regulation of prostitution and slaughterhouses — shows a state that sought revenue and control from every economic activity. This level of bureaucratic detail distinguishes Kautilya's vision from anything in the contemporary ancient world. The administrative architecture sketched here underlies all the policies Ashoka would later pursue, including those described in the Dhamma edicts covering hospital building (RE II) and Dhamma Mahamattas (RE V).
The Maurya Spy System (Guptacharas)
The Arthashastra's espionage system is one of the most elaborate in the pre-modern world. Spies (Guptacharas) were divided into two categories:
- Samstha — Stationary spies, embedded in specific roles: the wandering student (shatri), the household priest (grihapatika), the farmer, the merchant, the ascetic, the poisoner. Their cover identity was permanent.
- Sanchara — Roving spies who moved between assignments and reported on mobile targets.
The testing of ministers (upadhAs) was a specific application: the king would use agents to approach a minister with a bribe, then with a conspiracy, then with a religious temptation, to test whether the minister remained loyal. If a minister passed all four tests, he was deemed trustworthy.
Army Organisation — Megasthenes' Report
Megasthenes reported that the Maurya War Office consisted of 30 members arranged in six committees of five, each responsible for one wing of the military: navy, infantry, cavalry, war chariots, war elephants, and commissariat (supply). This "board" structure is distinctive and UPSC-tested.
The army's reported strength was staggering: 600,000 infantry, 30,000 cavalry, 9,000 elephants, and 8,000 chariots (some sources). Even allowing for Greek exaggeration, the Maurya army was the largest standing force of the ancient world at the time.
Economy and Revenue
The Maurya fiscal system had multiple revenue streams:
| Tax / Revenue | Description |
|---|---|
| Bhaga | The "share" — the main land tax, typically 1/4 to 1/6 of agricultural produce |
| Bali | Originally a religious offering; converted to a compulsory tax on peasants |
| Hiranya | Cash payment from those who could pay in money rather than kind |
| Kara | Additional levies on specific products or regions |
| Shulka | Customs duties on imports/exports; collected at city gates |
State monopolies (rajasva) covered mines, salt, weapons manufacture, and certain textile industries. The Akaradhyaksha supervised mines; the Lavanadhyaksha managed salt (a crucial commodity for food preservation in tropical India). Private traders could operate but paid tolls (shulka) at city gates.
Pataliputra: Capital of an Empire
The capital Pataliputra (modern Patna, Bihar) occupied the confluence of the Ganges and Son rivers — a site chosen for strategic and commercial reasons. Megasthenes described it as a massive city with a wooden palisade, 570 towers, and 64 gates.
The Pataliputra Capital (now in the Patna Museum) — a Persepolitan-style capital with scrolling volutes — was also found in the Patna area. It shows direct Persian (Achaemenid) influence on Maurya court art, likely mediated through the northwest satrapies that Chandragupta had acquired from Seleucus. The capital's polished surface is characteristic of the "Maurya polish" achieved on Chunar sandstone.
Maurya Art and Architecture
The defining material of Maurya court art is Chunar sandstone — quarried at Chunar near Varanasi (UP) and transported by river across the empire. Its characteristic features:
- Fine-grained buff/grey sandstone that takes an exceptional mirror polish
- Used for the monolithic pillars (12–15 metres tall, single-piece shafts) that Ashoka erected across the empire
- The polish was achieved by a technique not yet fully explained — it penetrates the surface rather than being a superficial coating
- Major pillar capitals at Sarnath, Rampurva (bull capital), and Vaishali (lion capital)
The pillars themselves are monolithic — single-piece shafts of stone, not assembled from drums — a feat of engineering that required precise quarrying, transport, and erection. They weighed between 40 and 50 tonnes.
Yaksha Sculptures
Yaksha and Yakshini (male and female nature deities) sculptures from the Maurya period represent some of the earliest large-scale stone figurative sculptures in Indian art. Two are of particular UPSC relevance:
The Didarganj Yakshini (now in the Patna Museum) was found at Didarganj, Patna in 1917. It was NOT found at Bulandibagh. Bulandibagh is the site of the Pataliputra palisade excavation. These are two different Patna localities and UPSC sets this as a location confusion trap.
The Didarganj Yakshini is a masterpiece of Maurya sculpture: 1.63 metres tall, carved from single-piece Chunar sandstone with the characteristic high polish, holding a fly-whisk (chamara). The Parkham Yaksha (Mathura Museum), also from this period, shows similar monumental scale but slightly less refined polish — suggesting regional variation in technique.
The Barabar Hill Rock-Cut Caves
The Barabar Hill caves in Jehanabad district, Bihar, are the oldest surviving rock-cut caves in India. Ashoka donated them to the Ajivika sect — a heterodox, fatalistic religious movement contemporary with Buddhism and Jainism — NOT to Buddhist monks. This is a classic UPSC trap. There are four main caves:
| Cave | Notable Feature |
|---|---|
| Lomas Rishi | Arched entrance façade carved to mimic wooden architecture — the earliest known example of an apsidal arch in Indian stone cutting; dedicated to Ajivikas by Ashoka |
| Sudama | Two chambers with a circular cell; inscription of Ashoka's 12th regnal year |
| Visvakarma (Karna Chaupar) | Single chamber with highly polished walls |
| Nagarjuni Caves | Nearby group; donated by Dasaratha (Ashoka's grandson) to Ajivikas |
The Lomas Rishi cave's façade deserves special attention: the horseshoe-shaped (chaitya) arch at the entrance is carved in stone but clearly imitates the thatched wooden architecture of the period. This "petrification of timber" technique — translating wooden forms into stone — characterises much of early Indian rock-cut architecture and connects these Maurya-era caves to the later Buddhist cave tradition at Bhaja, Karla, and Ajanta.
The artistic traditions established in this period — rock-cut architecture, monumental stone sculpture, the pillar-and-capital format — feed directly into the post-Maurya artistic efflorescence discussed in the Post-Maurya Period article covering Gandhara and Mathura schools.
The Fall of the Maurya Empire
After Ashoka's death (c. 232 BCE), the empire fragmented rapidly. Subsequent kings — Dasaratha, Samprati, Salisuka, Devavarman, Shatadhanvan, and finally Brihadratha — ruled over a progressively diminished territory. The western and northwestern provinces were lost to the Bactrian Greeks (Indo-Greeks) by around 180 BCE.
With reference to the Maurya art and architecture, consider the following statements:
1. The Maurya pillars were made of Chunar sandstone quarried in the Vindhyas.
2. The Didarganj Yakshini was discovered at Bulandibagh near Patna.
3. The Barabar Hill caves were donated by Ashoka to the Ajivika monks.
Statement 1: CORRECT — Chunar sandstone, quarried near Varanasi. Statement 2: FALSE — the Didarganj Yakshini was found at Didarganj, NOT Bulandibagh (Bulandibagh is the palisade site). Statement 3: CORRECT — Barabar caves were for Ajivikas, not Buddhists.
With reference to the Maurya Empire, which of the following statements is/are correct?
1. The empire was divided into four provinces under the administration of prince-viceroys.
2. Pushyamitra Shunga was the last Maurya king.
3. According to Megasthenes, the Maurya army included 600,000 infantry and 30,000 cavalry.
Statement 1: CORRECT — four provinces (Taxila, Ujjain, Suvarnagiri, Tosali). Statement 2: FALSE — the last Maurya king was Brihadratha. Pushyamitra KILLED Brihadratha and founded the Shunga dynasty. Statement 3: CORRECT — Megasthenes reports 600,000 infantry and 30,000 cavalry.
Frequently Asked Questions
Where was the Didarganj Yakshini found?
At Didarganj, Patna in 1917. Not at Bulandibagh (which is the Maurya palisade site). The Yakshini is in the Patna Museum. This location confusion is a standard UPSC trap.
Which sect were the Barabar Hill caves donated to?
Ajivikas — a heterodox fatalistic sect, not Buddhists. The four caves are Lomas Rishi, Sudama, Visvakarma, and Karna Chaupar. The Nagarjuni caves nearby were donated by Ashoka's grandson Dasaratha, also to Ajivikas.
Who killed the last Maurya king?
Pushyamitra Shunga, the Senapati (commander-in-chief), killed Brihadratha (the last Maurya king) around 185 BCE and founded the Shunga dynasty. Pushyamitra was NOT a Maurya — he was the overthrow agent.
What is the significance of Chunar sandstone for Maurya art?
Chunar sandstone (quarried near Varanasi) was used for all Ashokan monolithic pillars and major sculptures. It takes a distinctive mirror-like polish — the "Maurya polish" — that is the hallmark of imperial Maurya art. The pillars stand 12–15 metres tall from a single stone shaft.
What were the main revenue sources of the Maurya Empire?
Land tax (Bhaga = 1/4 to 1/6 of produce), Bali (compulsory levy), Hiranya (cash payment), Kara (additional levies), and Shulka (customs duties). State monopolies in mines, salt, weapons, and some textiles generated additional revenue.
