The Maurya Empire
INTRODUCTION AND SOURCES
The Maurya Empire was a geographically extensive Iron Age power in South Asia, centered in Magadha and founded by Chandragupta Maurya around 320 BCE. It existed in a loosely-knit form until its dissolution in 185 BCE. Written records of this period are primarily pieced together from partial accounts of Megasthenes's lost history preserved in later Roman texts, the Edicts of Ashoka—deciphered in 1838 by James Prinsep—and the Arthashastra. The Arthashastra, once attributed to Chanakya, is now considered a work by multiple authors from the first centuries of the Common Era, describing post-Mauryan customs. Archaeologically, the Mauryan period aligns with the era of Northern Black Polished Ware.
Chandragupta Maurya, through military action and diplomacy, overthrew the Nanda dynasty and expanded his rule west to Afghanistan and south to the northern Deccan. However, beyond the core Magadhan region, the era's technology and infrastructure limited the depth of his control. His grandson, Ashoka, briefly controlled the subcontinent's major urban hubs and arteries, except for the deep south. The empire's capital was Pataliputra in Magadha, with other core regions in Taxila, Ujjain, Kalinga, and the precious metal-rich lower Deccan plateau. Outside these core areas, the empire's reach depended on the loyalty of military commanders in scattered armed cities.
The empire's economy benefited from the rise of Buddhism and Jainism, which reduced the costs of economic transactions by promoting nonviolence and proscribing superfluous rituals. A common coinage and the use of writing also facilitated more complex business dealings. These factors supported maritime and river-borne trade, crucial for acquiring consumer goods and valuable metals. To aid commerce, the dynasty built roads, including the notable Uttarapath, a winter road connecting eastern Afghanistan to Pataliputra when rivers were low enough to be forded. Other roads linked the Ganges basin to the Arabian Sea and to mines in the south.
The population of South Asia during this period is estimated to be between 15 and 30 million. The empire’s dominion was marked by exceptional creativity in art, architecture, and texts, but also by the consolidation of caste in the Gangetic plain and the decline of women's rights in mainstream Indo-Aryan speaking regions.
ETYMOLOGY AND DYNASTIC SYMBOLS
In his edicts, Ashoka referred to his domains as Jambudīpa, the ancient Indian name for the subcontinent, while neighboring cultures often used exonyms like the Greek Indíā. The name "Maurya" itself does not appear in Ashoka’s edicts or in contemporary Greek accounts. It is attested later in sources such as the Junagadh rock inscription of Rudradaman, which prefixes "Maurya" to the names of Chandragupta and Ashoka, and in the Puranas, which use it as a dynastic name.
Buddhist texts state that Chandragupta belonged to the "Moriya" clan of the Shakyas, the same tribe as Gautama Buddha. According to Buddhist tradition, the clan's ancestors settled in a region abundant with peacocks (mora in Pali), leading to their name. Another account claims they built a city called Moriya-nagara, or "Peacock-city," with bricks colored like peacocks' necks. Jain texts connect Chandragupta to an imperial superintendent of peacocks (mayura-poshaka).
This connection to peacocks seems corroborated by archaeological evidence, such as peacock figures on the Ashoka pillar at Nandangarh and sculptures at the Great Stupa of Sanchi, leading modern scholars to theorize that the peacock was the dynasty's emblem. A later, less credible derivation by the 18th-century commentator Dhundhi-raja suggests the name comes from Mura, the mother of the first emperor, though Puranic texts make no such link, and Sanskrit rules would derive "Maureya" from the feminine Mura, not "Maurya".
FOUNDATION OF THE EMPIRE: CHANDRAGUPTA MAURYA
The empire's origins are shrouded in legend, with Greek sources focusing on Chandragupta's encounters with them and Indian sources detailing his conquest of the Nanda Empire. Indian accounts, like the Gupta-era drama Mudrarakshasa, describe his royal ancestry, even linking him to the Nanda family, while early Buddhist texts refer to a kshatriya clan known as the Mauryas. Greek accounts first mention Chandragupta as "Sandrokottos," and Plutarch states that as a young man, Chandragupta saw Alexander the Great.
Following Alexander the Great’s Indian campaigns, his army mutinied at the Beas River and refused to advance further east. Alexander returned to Babylon, redeploying his troops west of the Indus, and died soon after in 323 BCE, leading to the fragmentation of his empire. The Roman historian Justin records that after Alexander’s death, the people of India assassinated the Greek governors, a liberation led by Chandragupta. However, Justin notes that Chandragupta then "transformed liberation in servitude after victory, since, after taking the throne, he himself oppressed the very people he has liberated from foreign domination."
Chandragupta organized an army, which some early translators interpreted as a "body of robbers," but the original term may have meant mercenary soldiers. He recruited forces from the Punjab, including local military republics like the Yaudheyas that had resisted Alexander. After routing Alexander's remaining forces, Chandragupta engaged Seleucus I Nicator, who fought to defend the territories but was defeated and retreated into Afghanistan.
The Nanda Empire, a large, militaristic, and wealthy power, ruled the Ganges basin. Details of Chandragupta’s campaign against it are primarily from legends written centuries later. Buddhist, Jain, and Hindu texts agree that Chandragupta, with the counsel of Chanakya, conquered the Nanda dynasty. According to legend, Chanakya, a minister for the Nandas, was insulted by King Dhana Nanda and vowed revenge. He discovered the young Chandragupta and, seeing his imperial qualities, mentored him.
Initial attacks on the Nanda capital of Pataliputra were unsuccessful. Chandragupta and Chanakya then shifted their strategy to conquering territories on the frontier and gradually moved toward the capital, establishing garrisons along the way. They finally besieged Pataliputra, where Dhana Nanda was defeated. While Buddhist sources describe an easy victory, Hindu and Jain texts state the campaign was bitterly fought. With the fall of the Nandas, Chandragupta Maurya founded his empire.
Around 303-302 BCE, a confrontation occurred between Chandragupta and Seleucus I Nicator, who had consolidated the Asian portion of Alexander’s empire. As Appian wrote, Seleucus "crossed the Indus and waged war with Sandrocottus [Maurya]... until they came to an understanding with each other and contracted a marriage relationship." The two rulers concluded a dynastic marriage alliance, and Seleucus transferred the easternmost satrapies of his empire—certainly Gandhara, Parapamisadae, and parts of Gedrosia, and possibly Arachosia and Aria—to Chandragupta. In return, Seleucus received 500 war elephants, which proved decisive in his victory at the Battle of Ipsus in 301 BCE.
Following the treaty, Seleucus dispatched the ambassador Megasthenes to the Mauryan court at Pataliputra. Megasthenes's book, Indika, became a major literary source on the empire. Later, Deimakos was sent to the court of Chandragupta’s son, Bindusara, and Ptolemy II of Egypt sent an ambassador named Dionysius. The rulers also exchanged gifts, with Chandragupta once sending various aphrodisiacs to Seleucus.
Chandragupta established a decentralized state administered from Pataliputra, which Megasthenes described as a grand city "surrounded by a wooden wall pierced by 64 gates and 570 towers." He subdued all of India, an account corroborated by Tamil Sangam literature mentioning a Mauryan invasion of the south.
EXPANSION AND DIPLOMACY: BINDUSARA
Bindusara, son of Chandragupta and his wife Durdhara, ascended the throne around 297 BCE. At just 22 years old, he inherited a vast empire and extended it southward as far as modern-day Karnataka, conquering sixteen states and nearly the entire Indian peninsula, described as the 'land between the two seas'. He did not, however, conquer the friendly Tamil kingdoms of the Cholas, Pandyas, and Cheras, nor the kingdom of Kalinga. His life is not as well-documented as his father's or son's.
Chanakya continued as prime minister, helping Bindusara "to destroy the nobles and kings of the sixteen kingdoms and thus to become absolute master of the territory between the eastern and western oceans," according to the Tibetan scholar Taranatha. During Bindusara's reign, the citizens of Taxila revolted twice due to the maladministration of his eldest son, Susima. Bindusara could not suppress the second revolt, which was later crushed by his other son, Ashoka. Tamil poets from the Sangam literature described how the Mauryan army, with a vanguard of Vadugar troops from the Andhra-Karnataka region, invaded areas south of the Deccan Plateau.
Bindusara maintained friendly diplomatic relations with the Hellenistic world, receiving the ambassador Deimachus from the Seleucid king Antiochus I. He is also believed to be the king of Palibothra who welcomed the Greek author Iambulus. Pliny records that Ptolemy II Philadelphus of Egypt sent an envoy named Dionysius to India during his reign. In one exchange, Bindusara, known in Greek sources as Amitrochates, requested that Antiochus send him sweet wine, dried figs, and a sophist. Antiochus replied, "The dry figs and the sweet wine we will send you; but it is not lawful for a sophist to be sold in Greece."
Unlike his father, who later converted to Jainism, Bindusara followed the Ajivika religion. His guru was a Brahmin of the Ajivika faith, as was his wife, Empress Subhadrangi. He is credited with giving grants to Brahmin monasteries. Bindusara died in the 270s BCE, followed by a four-year struggle for succession, after which his son Ashoka became emperor.
THE ZENITH OF THE EMPIRE: ASHOKA
As a young prince, Ashoka was a brilliant commander who crushed revolts in Ujjain and Taxila. As emperor, he was ambitious and aggressive, reasserting imperial superiority in the south and west. The pivotal event of his life was his conquest of Kalinga between 262 and 261 BCE. Although his army overwhelmed the Kalinga forces, an estimated 100,000 soldiers and civilians were killed, including over 10,000 of his own soldiers. Witnessing the devastation firsthand, Ashoka felt remorse. After annexing Kalinga, he embraced the teachings of Buddhism and renounced war.
Ashoka implemented principles of ahimsa (non-violence) by banning hunting and abolishing the slave trade. While maintaining a large army to keep peace, he expanded friendly relations with states across Asia and Europe and sponsored Buddhist missions. He also undertook a massive campaign of building public works. The Edicts of Ashoka, inscribed on stone pillars and rocks, are found throughout the subcontinent, from Afghanistan to Andhra. Written mostly in Prakrit, with some in Greek and Aramaic, they state his policies and accomplishments. The edicts name Hellenistic rulers such as Antiochus II, Ptolemy II, Antigonos II, Magas of Cyrene, and Alexander II of Epirus as recipients of his Buddhist proselytism, accurately locating their territories as "600 yojanas away."
DECLINE AND SUCCESSION
After Ashoka's death, he was followed by a succession of weaker emperors over 50 years. His grandson, Dasharatha Maurya, succeeded him as none of his sons could take the throne. The empire lost territory under Dasharatha, which was later reconquered by Samprati, another of Ashoka's grandsons. After Samprati, the Mauryas continued to lose territory.
Around 206 BCE, the Seleucid king Antiochos III renewed his friendship with a Mauryan ruler in the region south of the Hindu Kush, whom Greek sources name Sophagasenus (Subhagasena). This ruler, possibly a grandson of Ashoka, ruled in the Gandhara region and provided Antiochos with more war elephants.
In 180 BCE, the last emperor, Brihadratha Maurya, was assassinated by his general, Pushyamitra Shunga, during a military parade, leading to the rise of the Shunga Empire. Reasons for the empire's decline include a succession of weak rulers, the partition of the empire, the growing independence of certain regions, and a top-heavy administration. Some historians have argued that Ashoka's pacifism undermined the empire's military strength, though others suggest this has been exaggerated. Buddhist records claim the rise of the Shunga empire led to a wave of persecution against Buddhists and a resurgence of Brahmanism, though archaeological evidence for widespread persecution is lacking.
The fall of the Mauryas left the Khyber Pass unguarded, and the Greco-Bactrian king Demetrius conquered southern Afghanistan and parts of northwestern India around 180 BCE, establishing the Indo-Greek Kingdom. The Indo-Greeks maintained control of the trans-Indus region for about a century, during which Buddhism flourished under kings like Menander. Their rule was eventually ended by invading Indo-Scythian tribes around 70 BCE.
IMPERIAL ADMINISTRATION AND MILITARY
The empire wielded one of the largest armies in the Iron Age. According to Megasthenes, it included 600,000 infantry, 30,000 cavalry, 8,000 chariots, and 9,000 war elephants. Military command was organized through six boards of five members each, responsible for the Navy, Military Transport, Infantry, Cavalry and Catapults, Chariot Divisions, and Elephants. A vast espionage system collected intelligence for both internal and external security. Even after renouncing offensive warfare, Ashoka maintained this large army to protect the empire and ensure stability.
The empire was organized with a sophisticated civil service, as described in the Arthashastra. It consisted of five parts: the center, composed of Magadha and its capital Pataliputra, was directly ruled by the emperor and his Council of Ministers (Mantriparishad). The other territories were divided into four provinces with capitals at Tosali (east), Ujjain (west), Suvarnagiri (south), and Taxila (north). These were governed by a prince (Kumar), who was assisted by great ministers (mahamatyas).
However, many scholars now view the empire not as a uniformly controlled territory but as a network of core areas and trade routes, with inscriptions and edicts absent from large parts of the interior, suggesting these regions remained autonomous. Control of trade routes was essential, as they were threatened by undefeated tribes.
Local government in cities was managed by a council of thirty commissioners divided into six boards. These boards oversaw industries, foreign dignitaries, registrations, manufactured goods, trade regulation, and the collection of sales taxes. The official head of a village was the Gramika, and in towns, the Nagarika. A regular census enumerated people by vocation—such as traders, agriculturists, and smiths—as well as cattle, primarily for taxation purposes. This vocational enumeration helped consolidate the caste system.
There was no private ownership of land, as it all belonged to the emperor. In return for tribute paid by the laboring class, the emperor supplied agricultural products, animals, tools, and public infrastructure, creating what some have described as a "socialized monarchy" or an early welfare state.
ECONOMY, TRADE, AND INFRASTRUCTURE
For the first time in South Asia, political unity and military security fostered a common economic system, enhancing trade and agricultural productivity. A centralized, fair system of taxation replaced the burdens imposed by hundreds of regional kings. Chandragupta Maurya established a single currency, with coins made mostly of silver and copper, and his administration provided justice and security for merchants and farmers by eliminating bandits and regional private armies.
The Mauryas sponsored public works, including waterways, to increase productivity. An international trade network expanded under the Indo-Greek friendship treaty and during Ashoka's reign. The Khyber Pass became a vital port of trade with the Hellenistic kingdoms in West Asia. Trade also extended through the Malay Peninsula into Southeast Asia, with Indian exports including silk, textiles, spices, and exotic foods. This trade introduced new scientific knowledge and technology to the external world. Ashoka sponsored the construction of thousands of roads, canals, hospitals, and rest-houses, further boosting economic activity across the empire. The economic situation was in many ways analogous to the later Roman Empire, with both having extensive trade connections and organizations similar to corporations, though Mauryan India had numerous private commercial entities that predated the empire itself.
RELIGION AND SOCIETY
While Brahmanism was an important religion throughout the period, the empire was centered in the non-Vedic region of Magadha and favored Jainism, Buddhism, and Ajivikism. The establishment of the empire was a setback for traditional Brahmanism, which lost its courtly privileges and was pressured to reinvent itself as a socio-political ideology, eventually leading to the Hindu synthesis that incorporated local and sramana traditions.
According to a 12th-century Jain text, Chandragupta Maurya embraced Jainism late in life, renouncing his throne to join a group of Jain monks and fasting to death at Shravana Belgola in Karnataka. His grandson Samprati also patronized Jainism, building thousands of Jain temples (derasars) and reportedly sending missionaries to Greece and the Middle East.
Bindusara, in contrast, followed Brahmanism, according to Buddhist texts which call him a "devotee of the Brahmins." Ashoka embraced Buddhism after the Kalinga War. He sent missions led by his son Mahinda and daughter Sanghamitta to Sri Lanka, where the king adopted Buddhism as the state religion. He also sent missions to West Asia and Southeast Asia, commissioned monasteries, and is believed to have built as many as 84,000 stupas, such as those at Sanchi and Mahabodhi. His patronage, including the convening of the Third Buddhist Council, was crucial in elevating Buddhism to a world religion.
The period saw the consolidation of the caste system among the Indo-Aryan peoples of the Gangetic plain as they incorporated tribal groups, and a decline in the rights of women in these regions.
ART, ARCHITECTURE, AND NATURAL HISTORY
The greatest monument from the early empire was Chandragupta’s palace at Pataliputra, which, according to Megasthenes, was chiefly constructed of timber and exceeded the palaces of Susa and Ecbatana in magnificence, with gilded pillars adorned with golden vines and silver birds. Excavations have unearthed a large pillared hall with 80 columns. Later stone column fragments indicate that Ashoka replaced the earlier wooden structures with stone.
During Ashoka's reign, stonework became highly diversified and perfected, comprising free-standing pillars, stupa railings, and colossal figures, all given a high, lustrous polish. This period marked the beginning of Buddhist architecture. Ashoka was responsible for constructing numerous stupas—large domes bearing symbols of Buddha—with the most important ones located at Sanchi, Bodhgaya, and Bharhut. The most widespread examples of Mauryan architecture are the more than 40 exquisitely decorated Ashoka pillars and carved edicts spread across the subcontinent.
The Mauryas were the first empire in India to provide a unified political entity, and their attitude toward nature is of historical interest. They viewed forests as resources, with the elephant being the most important product for its military value. They designated forests to protect supplies of timber as well as lions and tigers for skins. After Ashoka embraced Buddhism, he brought significant changes, providing protection to fauna and relinquishing the royal hunt. He was one of the first rulers in history to advocate for wildlife conservation, with stone edicts proclaiming his policies. One edict states, "Our king killed very few animals." However, the mention of fines for poaching indicates that these rules were not always followed.
RELATIONS WITH THE HELLENISTIC WORLD
A large Greek population was present in the northwest of the subcontinent during Ashoka's rule, likely remnants of Alexander's conquests. Ashoka's Rock Edicts, some inscribed in Greek, state that the Greeks within his dominion were converted to Buddhism. An edict found in Kandahar, written in both Greek and Aramaic, uses the word Eusebeia (Piety) as the Greek translation for Dharma.
Ashoka sent Buddhist missions to the West, mentioning Hellenistic kings as recipients of his proselytism, though no Western historical record of this remains. He also encouraged the development of herbal medicine for both humans and animals in his and neighboring territories. Greeks in India appear to have played an active role in spreading Buddhism; Pali sources describe emissaries like Dharmaraksita as a leading Greek ("Yona") Buddhist monk active in proselytism.
Concise Summary
The Maurya Empire, founded by Chandragupta and reaching its zenith under Ashoka, unified much of South Asia through military conquest, sophisticated administration, and extensive trade networks. It left a lasting legacy in governance, art, and the global spread of Buddhism before declining due to weak succession and foreign invasions.
