Introduction

The Mauryan Empire (c. 322-185 BCE) was India's first major pan-subcontinental empire, founded by Chandragupta Maurya with the strategic guidance of his mentor Kautilya (Chanakya), and reaching its zenith under Ashoka, whose post-war transformation remains one of ancient history's most compelling narratives.

Chandragupta Maurya (c. 322-298 BCE)

  • Overthrew the last Nanda ruler, Dhana Nanda, with Kautilya's strategic guidance, founding the Mauryan dynasty.
  • Defeated Seleucus I Nicator (Alexander's successor in the East) around 305 BCE; the resulting treaty gave the Mauryas control of the Hindu Kush/Afghanistan region in exchange for 500 war elephants, and led to a matrimonial alliance and the posting of the Greek ambassador Megasthenes at the Mauryan court.
  • Reportedly abdicated late in life, became a Jain monk under Bhadrabahu, and died at Shravanabelagola (Karnataka) by fasting unto death (Sallekhana).

Kautilya's Arthashastra

A comprehensive treatise on statecraft, economics, and military strategy — describes the Saptanga theory of state (seven elements: king, minister, territory, fort, treasury, army, ally) and forms the primary indigenous source for understanding Mauryan administration.

Bindusara (c. 298-273 BCE)

Chandragupta's son; extended Mauryan control further into the Deccan; maintained diplomatic relations with the Hellenistic world (Greek sources mention his correspondence with Antiochus I of Syria).

Ashoka the Great (c. 268-232 BCE)

Flowchart — Ashoka's Transformation
Kalinga War (c. 261 BCE) — massive bloodshed and suffering witnessed firsthand
↓
Deep remorse (recorded in the Thirteenth Major Rock Edict); embraces Buddhism
↓
Adopts and propagates "Dhamma" — a policy of moral/ethical governance, not a specific religious conversion mandate

Ashoka's Dhamma — Key Principles

  • Respect for all life (ahimsa), tolerance for all sects and beliefs, obedience to parents/elders, kindness to servants and slaves.
  • Appointed special officers, "Dhamma Mahamatras," to spread and monitor Dhamma across the empire.
  • Sent Buddhist missionaries abroad, including his son Mahinda and daughter Sanghamitra to Sri Lanka.
  • Convened the Third Buddhist Council at Pataliputra.

Ashoka's edicts were inscribed on rocks and pillars across the empire in Prakrit (Brahmi script mostly, Kharosthi in the northwest, Aramaic/Greek in the far northwest) — deciphered by James Prinsep in 1837.

Mauryan Administration

LevelStructure
CentralKing as supreme authority, assisted by a council of ministers (Mantriparishad)
ProvincialEmpire divided into provinces, often governed by royal princes (Kumaras) — e.g., Taxila, Ujjain, Suvarnagiri, Tosali
EspionageElaborate spy network (per Arthashastra) to monitor officials and public opinion
City administrationMegasthenes describes a Pataliputra city administration with six committees of five members each, overseeing crafts, foreigners, births/deaths, trade, manufacture, and tax collection

Decline of the Mauryan Empire

  • Weak successors after Ashoka; the empire fragmented under the pressure of provincial governors' revolts and external invasions.
  • Last Mauryan ruler, Brihadratha, was assassinated by his own commander-in-chief, Pushyamitra Shunga (c. 185 BCE), who founded the Shunga dynasty.
