The Mauryan Empire of Ancient India

The Mauryan Empire of India was a huge ancient state which, at its peak, covered much of the Indian subcontinent. In so far as comparisons can be made, it was to India what the Han Empire was to China and the Roman Empire was to the West.

Its main contribution to later Indian history was probably to spread the Aryan civilization, which had emerged in northern India, down into central India and towards southern India. So far as world history is concerned, however, it holds out another significance. This is that it provides an almost unique example of a saintly ruler who was at the same time a wise and realistic statesman. This figure was the emperor Ashoka, whose long reign occurred while the Mauryan Empire was at the height of its power. As a Buddhist, moreover, he was in a position to promote his faith, and he took full advantage of this opportunity. It may well be that Buddhism’s dominant place amongst the religions of South East Asia is testimony to his missionary zeal.

Origins of The Mauryan Empire

Prior to the rise of the Maurya, numerous states, large and small, covered northern India. This was the classical age of the history of ancient India, a time of religious ferment when two new faiths, Buddhism and Jainism, appeared.

One of the largest of these states was Magadha. It was located in the eastern part of the Ganges plain, on the periphery of the Aryan cultural area. At this stage in Indian history other states apparently regarded Magadha as semi-barbarous. Perhaps its position on the frontiers of the Aryan world meant that its people were not too strict in their commitment to the old Vedic religion of northern India. It is certainly the case that the two non-orthodox faiths of Jainism and Buddhism flourished here in their early days, and found patrons amongst the Magadha kings.

Gradually, over a century or more, Magadha extended its borders. Then, under a line of kings of the Nanda dynasty (reigned c. 424-322 BCE), the kingdom dramatically expanded, to cover a large part of northern India.


The Mauryan period of ancient Indian history was really inaugurated by the conquest of northwest India by Alexander the Great, in 326 BCE. This seems to have destabilized the political situation amongst the Aryan states in the region, allowing the first great conqueror in Indian history, Chandragupta Maurya (reigned 322-298 BCE), to rise to power.

Chandragupta seized control of the throne of Maghada from the last Nanda king, and then proceeded to conquer that part of northern India which still remained outside Magadha’s borders. He defeated Seleucus, one of the successors of Alexander who had gained control of most of his conquests in Asia, and in a treaty dated 305 BCE was given Seleucus’ easternmost provinces, reaching into Afghanistan and eastern Iran, in exchange for 500 war elephants.

Internally, building on foundations laid by the Nanda kings, his reign saw the establishment of a strong central government. This was the work of his highly capable chief minister, Chanakya.

Chandragupta was succeeded by his son, Bindusara (reigned 298-272 BCE). We know next to nothing about him, but he must have been a successful ruler. He extended Mauryan power far down into central India, and bequeathed a huge, unified state to his son, Ashoka.


Ashoka (also spelt Asoka – reigned 272-232 BCE) proved to be one of the most remarkable, and attractive, rulers in the history of India, and indeed the whole of world history.

After a bloody war against Kalinga, in eastern India, Ashoka renounced warfare and converted to Buddhism. He determined that henceforward he would reign in peace.

He actively promoted the spread of Buddhism; and sent missions abroad, to Sri Lanka (headed by his son, Mahinda) and South East Asia. Here they laid the foundations for Buddhism’s later triumph as the predominant faith. He also sent missions to the Greek-speaking kingdoms to the west, which had carved up Alexander the Great’s conquests between them. Here they seem to have made little impact.

We can still see the pillars Ashoka erected around his empire, on which were inscribed royal edicts and encouragements to his subjects to live in harmony with one another. These edicts and exhortations give an insight into Ashoka’s mind. What comes across is a compassionate, tolerant but firm ruler, seeking justice and well-being for all his subjects.

Mauryan Government

There seems little doubt that one of the main architects of Maurya power was Chandragupta’s chief minister, Chanakya. He is widely regarded as the author of a political treatise called the Arthashastra, a down-to-earth manual on how to rule. Although most scholars agree that this work was in fact written a long time after the Maurya had left the stage, many think it does reflect conditions from that time. In any case, Chanakya seems to have organized an efficient military and civil administration, on which the Mauryan kings could build a solid power.

Maurya kings were advised by a council of advisors, and was served by an elaborate administrative structure. The empire was divided into provinces, each governed by a member of the royal family. Under them, local rulers seem to have been kept in place, if they were loyal to the Maurya and forwarded the taxes from their domains promptly to the imperial treasury in the capital. Their activities, however, were checked on by senior royal officials, through regular inspections, and also watched by Mauryan spies, secretly. The Mauryan regime had an extensive espionage system, which Chandragupta in particular used to great effect.

The cities of the empire were directly administered by a hierarchy of royal officials, responsible for the upkeep of such public facilities as roads and wells, and for the maintenance of justice.

Mauryan power rested ultimately on its formidable army, which Greek and Roman authors regarded (probably wrongly) as the largest in the world at that time. One claimed that it included 700 elephants, 1000 horses and 600,000 infantry, surely an exaggeration.

The Mauryan government and the economy

As with most ancient administrative systems, the Mauryan bureacracy’s main purpose was to collect taxes. These consisted primarily of the land tax. Since this depended on agricultural prosperity, the government sponsored the reclamation of large amounts of land from forests and wastelands (it seems to have been illegal for private persons to clear land). Irrigation projects were undertaken to increase productivity.

Taxes were also levied on trade, and trade was officially encouraged. The construction of a network of roads, certainly as much for military as commercial purposes, will have significantly affected trade for the better; and such measures as the planting of roadside trees for shade; and the construction of rest houses every few miles, illustrates the government’s concern in this area.

Economy and society

The Mauryan period, particularly during the reign of Ashoka, was one of the very few times in Indian history when the population as a whole experienced an extensive period of peace. As always, peace encouraged prosperity, and as we have seen, the government actively sponsored agriculture and trade. Trade routes would have been more secure than at any time before in ancient India, and indeed for most periods since. This would have made long-distance commerce easier.

The archaeological record suggests that the standard of living rose appreciable under Mauryan rule. Iron implements came into wider use, which would have helped the reclamation of land for farming, and led to greater productivity for farmers. Metal coinage became more widespread, which would have stimulated trade. The expansion of trade is reflected in the spread of northern pottery styles into south India. Palitpura, the Mauryan capital, was a large and imposing city.

Links with other regions of the world

The Mauryan government was in regular diplomatic relations with the Greek-speaking kingdoms to its west. This was of course specially true for the Seleucid empire, the nearest, but contacts with Macedonia, Egypt and other kingdoms of the Hellenistic world are also mentioned. One of the Seleucids’ ambassadors to the Mauryan court was an official called Megethsenes, from whose account, the Indica, we can glean much information about India at the time of the Mauryan empire. There seem to have been marriage alliances between the Seleucid and Mauryan royal families.

These diplomatic relations also involved trade missions, and under Ashoka, missionary expeditions as well. In 251 BCE Ashoka’s son, Mahinda, led a missionary expedition which introduced Buddhism to Sri Lanka.


Buddhism flourished under the Maurya. Some scholars believe that it was in this period of ancient India, especially under Ashoka, that Buddhism became established as a major religion within the Indian sub-continent. Jainism also flourished, especially amongst the merchants of the cities – who, as we have seen, were experiencing a time of prosperity. The merchants were to some extent on the margins of the early Hindu scheme of society. They would probably have been less patient than other social groups with the traditional Brahmin dominance over religious matters, and hence more attracted to the new heterdox faiths of Buddhiam and Jainism.

Fifty years or so after Ashoka’s death, perhaps sooner (there is very little evidence from the later Maurya period), the huge empire began to crumble. Outlying provinces fell away: a large kingdom in central India, Satavahana, appeared, and in the northwest the India-Greek kingdom of Bactria, in present-day Afghanistan, expanded its territory deep into India. These developments heralded the break-away for more provinces, and by the mid-2nd century BCE, the former empire had shrunk to its core areas.

By that time, the Maurya dynasty itself had fallen. In 180 BCE a coup by the chief minister had resulted in the assassination in the last Maurya ruler whilst reviewing his army, and the establishment a new dynasty, the Shunga, in power.

The kingdom of Magadha itself survived, however. After a century the Shunga dynasty was succeeded by the Kanva dynasty in 73 BCE, and this in turn fell from power in 30 BCE. Thereafter the kingdom seems to have been at times under the suzerainty of neighboring states, and at other times ruled by obscure lines of kings. At the end of the 3rd century CE, however, a new line of kings came to power in Magadha, and went on to form the great Gupta empire, the largest and most successful state in India since the time of the Maurya.

Causes of decline

Why did this decline set in, and why was it so rapid?

Ashoka has sometimes been blamed for sowing the seeds of decline by his too-gentle rule. He might have left unchecked destabilizing forces, which came to full power after he was gone.

For this idea there is no evidence; indeed the edicts scattered around the empire suggest a firm and vigorous ruler. The causes of decline probably lie elsewhere, and can be summarized as follows:

First, Ashoka seems to have been followed by a succession of weak rulers, who could not exert their will over such a large empire.

This is related to the second reason, the Maurya’s failure to develop robust imperial institutions. Unlike the Han empire in China, which continued to run smoothly for almost 400 years, even when the emperors were nonentities, the effectiveness of Mauryan rule was always directly dependent upon the personal ability and energy of the king.

Later experience from around the world – for example, from China and the Roman empire – shows that, unless there is a well-working system for selecting and promoting capable and comparatively honest officials, a bureaucracy can soon become fragmented amongst the followers of over-powerful ministers and provincial governors. Something like this may well have occurred in late Maurya times, culminating in the breaking-away of large provinces from the empire.

Finally, the fragmentation of the Mauryan empire was, to some extent, a product of its very success. During the peace and unity the Mauryan kings had brought ancient India, Aryan culture had spread throughout much of the sub-continent. Towns and cities had sprung up – normally as centers of Mauryan administration – in places distant from the old seats of civilization. Economic development had come to areas which were previously the abode of forest peoples, of nomads and hunter-gatherers. All this had put in place the economic and administrative foundations upon which new, independent states could be built; and, with the firm hand of the early Mauryan kings gone, such states soon appeared.

The Mauryan legacy

In later Indian records, the Mauryan empire appears only as an entry in the long list of kingdoms that made up the vast and complex history of India; no special significance was attached to it.

No magnificent architecture was left – the towns where the Maurya carried out most of their building work continued to be lived in right up to the present day, and so Mauryan remains are buried under streets and buildings used by later generations.

Apart from a few brief mentions in some accounts, this great empire was all but forgotten – an astonishing fact given the great importance accorded by peoples in other parts of the world to their ancient empires.

In the 19th century, however, some British officials began to wonder, who built those mysterious pillars dotted around India? How come they are hundreds – thousands – of miles apart from one another? What do the inscriptions on them mean?

Then the truth about the Maurya gradually began to emerge. When it was realised that these pillars were the work of one king, Ashoka, whose realm covered a vast area of India and beyond, it was realised that here was a phenomenon of huge significance for the history of ancient India.

The Mauryan empire in world history

The Mauryan empire was the first great empire of the history of ancient India, and that in itself gives it major importance in world history.

It was one of the great empires of the ancient world; in size if not in longevity it was on a par with the Persian, Roman and Han empires.

The spread of Indian civilization

The Mauryan empire spread Aryan culture throughout most of India. It stimulated the economic development of then-peripheral regions, as these were incorporated into Aryan society. The Deccan, that great plateau covering most of central India, was, prior to its conquest by the Mauryans, mostly outside the boundaries of Aryan civilizations. Under the Maurya, it was incorporated into the Aryan world, and would play a key part in future periods of India’s history. In accomplishing this, the Mauryan empire vastly expanded the horizons of ancient Indian civilization, and so made it a more powerful force in world history.

In due course, the Deccan, and later southern India, which only under the Maurya began to be drawn into what we today think of as Indian culture, would play a pivotal role in the development of Indian Ocean trade networks, and act as a bridge for goods and ideas between the Middle East and South East Asia.

The spread of Buddhism

The Mauryan empire played a key role in the spread of Buddhism. It is quite possible that it was the Mauryan period which saw Buddhism’s establishment as a major religion within ancient India – a development encouraged by official policy under Ashoka. This will have helped establish the sub-continent as a base from which Buddhism could later spread to other parts of Asia.

Moreover, the Maurya directly promoted Buddhist missions to other regions, and although in most cases it was only later that the peoples of many of these countries became Buddhist to any large extent, these Maurya missions seem to have been directly responsible for the conversion of the ruling class of at least one country, Sri Lanka.

In any case, the fact that China, Japan, Korea, Vietnam, Tibet, Burma, Thailand, Laos and Cambodia all now have large Buddhist populations is in some part owing to the great Maurya king, Ashoka.

A saintly ruler

Ashoka offers a rare example in world history of a saintly yet capable ruler. Although his outstanding personality was hidden in the historical records until the 19th century, since then it has given all those who study world history pause for thought. As world history becomes a subject of more widespread study, his example can only become more widely known.

Institutional failure

Nevertheless, there is a negative side to the Maurya’s role in world history: their failure to create an empire that endured for more than a century. This meant it did not play in Indian history the role that the Han empire played in Chinese – that is, act as a powerful model for a unified government system which future generations would set about recreating, and leaving to them the institutional means by which they could do that.

Unlike in Chinese history, the history of India is not one of a succession of great empires under which the sub-continent was united under a single regime. It is interesting to ponder the question – had the Mauryas succeeded in creating a tradition of unity, and Indian history had been more like China’s, with a series of great empires providing unity and strength for the nation as a whole, how would world history have been different?

It would be one and half millennia before India again came near to unification, under the Delhi Sultanate – and then only very briefly. Likewise the Mughals and the British after them achieved brief moments of unity; but there was no ingrained habit of unity, no urge to merge, which rulers could draw on – a situation so different in Chinese history, where the only truly legitimate rulers are those who govern the entire (or at least the bulk) of that giant country.
