Sources for Mauryan history

The Mauryan Empire (c. 322–185 BCE) marks a watershed period in Indian history, transitioning from proto-historic regional kingdoms to a centralized pan-Indian empire. Reconstructing this era requires a multidisciplinary approach, balancing indigenous literature, foreign accounts, and archaeological epigraphy.

Literary Sources: Indigenous Texts

Indigenous literature provides deep insights into the administrative, socio-economic, and political framework of the Mauryan state.

Arthashastra by Chanakya (Kautilya)

• Nature of the Text: A comprehensive treatise on statecraft, economic policy, and military strategy written in Sanskrit. It contains 15 books (Adhikarana) and 180 sub-sections.
• Key Content: It details the Saptanga theory of state (seven limbs of the state: Swami, Amatya, Janapada, Durga, Kosha, Danda, and Mitra). It also mentions a vast espionage network (Gudha Purushas) and municipal administration.
• Prelims Fact: The text does not explicitly mention the name of Chandragupta Maurya or his capital, Pataliputra, focusing instead on abstract principles of governance.

Mudrarakshasa by Vishakhadatta

• Nature of the Text: A historical Sanskrit drama composed during the Gupta period (c. 4th–5th Century CE).
• Key Content: It narrates the political machinations of Chanakya to overthrow the Nanda Dynasty and establish Chandragupta Maurya on the throne.
• Socio-Cultural Value: It refers to Chandragupta Maurya as Vrishala or Kula-hina (of low clan/origin), reflecting later Brahmanical perspectives.

Puranas

• Nature of the Text: Traditional sectarian Hindu texts compiled across centuries.
• Key Content: The Vishnu Purana provides chronological lists of Mauryan kings and asserts that the dynasty was of Shudra origin, aligning with the geopolitical shift away from Kshatriya hegemony.

Buddhist and Jain Traditions

• Buddhist Chronicles (Mahavamsa and Dipavamsa): Sri Lankan Pali chronicles that describe the role of Ashoka in spreading Buddhism to Ceylon (Sri Lanka) via his children, Mahinda and Sanghamitta.
• Divyavadana and Ashokavadana: Sanskrit Buddhist texts detailing Ashoka’s early cruelty, his conversion to Buddhism, and his pilgrimage to holy sites.
• Jain Texts (Parishishtaparvan by Hemachandra): Details the later life of Chandragupta Maurya, confirming his conversion to Jainism under the guidance of Acharya Bhadrabahu and his subsequent voluntary starvation (Sallekhana) at Shravanabelagola, Karnataka.

Literary Sources: Foreign Accounts

Foreign accounts supply critical chronological anchors and external observations of Mauryan society.

Indica by Megasthenes

• Context: Megasthenes was the Greek ambassador sent by Seleucus I Nicator to the court of Chandragupta Maurya. The original text is lost, but fragments survive in the later works of Strabo, Arrian, Diodorus, and Pliny.
• Administrative Details: Describes the administration of Pataliputra through six municipal boards consisting of five members each.
• Socio-Economic Observations: Megasthenes divided Indian society into Seven Castes (Philosophers, Farmers, Herdsmen, Artisans, Soldiers, Overseers, and Councilors).
• Key Anomalies for Prelims: Megasthenes erroneously noted that there was no slavery in India, that Indians did not know the art of writing, and that famines never occurred in the subcontinent—claims contradicted by indigenous sources like the Arthashastra and Ashokan edicts.

Classical Greek and Roman Accounts

• Sources: Works by Justin, Plutarch, and Strabo.
• Key Identification: These texts refer to Chandragupta Maurya as Sandrocottus or Androcottus. Sir William Jones was the first scholar to identify Sandrocottus as Chandragupta Maurya, establishing a secure sheet-anchor for ancient Indian chronology.

Epigraphic Sources: Ashokan Edicts

Ashokan Edicts represent the earliest decipherable deciphered inscriptions in India. They were deciphered by James Prinsep in 1837, who identified the king mentioned as Devanamppiya Piyadasi (Beloved of the Gods, He of Pleasant Regard) with Ashoka.

Classification of Edicts

Key Major Rock Edicts (MRE) and Content

• MRE I: Prohibits animal slaughter, especially festive gatherings (Samajas).
• MRE II: Mentions medical treatment for humans and animals. Explicitly names South Indian kingdoms outside the empire: Cholas, Pandyas, Satyaputras, Keralaputras, and Tamraparni (Sri Lanka).
• MRE III: Orders the Rajukas and Pradesikas (administrative officers) to go on tours of inspection every five years (Anusandhana).
• MRE V: Mentions the appointment of Dhamma Mahamattas (officers of righteousness) for the first time in his 13th regnal year.
• MRE VIII: Mentions Ashoka’s first Dhamma Yatra (pious tour) to Bodh Gaya and the Bodhi Tree.
• MRE XII: Pleads for religious tolerance among different sects (Pasandas).
• MRE XIII: The longest edict. It details the Kalinga War (fought in the 8th regnal year, c. 261 BCE) and names five contemporary Hellenic kings: Antiochus II of Syria, Ptolemy II of Egypt, Antigonus of Macedonia, Magas of Cyrene, and Alexander of Epirus.

Crucial Minor Rock and Pillar Edicts for Prelims

• Maski and Gujarra Minor Rock Edicts: Distinctive because they mention the actual personal name “Ashoka“, rather than just his titles. Other sites doing so include Nitur and Udegolam.
• Bhabru-Bairat Rock Edict: Ashoka openly declares his faith in the Buddhist triad: Buddha, Dhamma, and Sangha.
• Rummindei Pillar Inscription (Lumbini, Nepal): A commemorative pillar marking the birthplace of Buddha. It states that Ashoka exempted the village from the Bali (religious tax) and reduced the Bhaga (land revenue tax) from 1/6th to 1/8th.
• Nigliva Pillar Inscription: Records that Ashoka enlarged the stupa of the Buddha Konakamana to double its original size.
• Schism Edicts (Sanchi, Sarnath, and Kosambi): Warns Buddhist monks and nuns against creating divisions in the Sangha, threatening them with expulsion.

Linguistic and Script Diversity

• North-Western Subcontinent: Edicts found in Shahbazgarhi and Mansehra are written in the Kharosthi script (written from right to left).
• Afghanistan: Inscriptions found at Kandahar (Shar-i-Kuna) are bilingual and biscriptual, written in Greek and Aramaic.
• Rest of the Subcontinent: Written in Prakrit using the Brahmi script (written from left to right).

Archaeological and Numismatic Sources

Physical material culture provides empirical proof validating the socio-economic scale of the empire.

Northern Black Polished Ware (NBPW)

• Nature: A highly glossy, metallic-looking pottery style characteristic of the Iron Age in northern India.
• Significance: The peak phase of NBPW coincides directly with the Mauryan period, indicating urban expansion, commercial growth, and widespread elite consumption patterns across the subcontinent.

Material Architecture

• Pataliputra Excavations: Spooner’s excavations at Kumrahar (modern Patna) revealed the remains of a vast 80-pillared wooden hypostyle hall, validating Megasthenes’ accounts of the luxury of the Mauryan royal palace.
• Barabar and Nagarjuni Caves: Located near Gaya, Bihar. These represent the earliest surviving rock-cut caves in India. Ashoka dedicated the Barabar caves (e.g., Lomas Rishi and Sudama caves) to the Ajivika sect, showcasing state-sponsored religious pluralism.

Numismatics: Punch-Marked Coins

• Metallic Composition: Primarily silver (Pana) and copper (Mashika or Kakini).
• Design: These coins lack inscriptions or royal portraits. Instead, they feature symbols punched onto the metal surface, including the sun, a six-armed symbol, hills, crescents, trees, and animals (peacock, elephant).
• Economic Inference: The uniformity of symbols across vast geographical expanses indicates a highly centralized, integrated monetary economy controlled by state mints (Lakshanadhyaksha).
