The ruins that ask an uncomfortable question
There are ruins that tell us how a civilisation lived. There are others that force us to confront what happens when power decides what deserves to survive.
Nalanda, in present-day Bihar, was among the most remarkable centres of organised learning in the Indian subcontinent. For centuries, its monastic and scholarly community attracted students, teachers and intellectual pilgrims from across Asia. Its legacy was not merely a collection of buildings: it was a living institution in which ideas were taught, debated, copied, challenged and carried beyond the walls of the monastery.
Yet Nalanda is remembered not only for what it achieved, but also for the destruction and decline that overtook it. Its story asks a question that remains relevant: when military power encounters an institution devoted to knowledge, what determines whether that institution survives?
Nalanda: an institution built around the life of the mind
Nalanda was a major Buddhist monastic and educational institution, flourishing over many centuries. The surviving archaeological remains reflect a substantial complex of monasteries, shrines, courtyards and teaching spaces. Its intellectual life formed part of a wider Asian network through which teachers, manuscripts, philosophical traditions and ideas travelled.
Buddhist philosophy was central to Nalanda’s identity, but its scholarly activity extended to logic, grammar, medicine, astronomy and other fields of learning. Its importance lay in more than the subjects taught. It represented a sustained commitment to organised study, disciplined argument and the preservation and transmission of knowledge across generations.
That commitment depended on conditions that scholarship alone could not guarantee: patronage, resources, institutional continuity and a measure of political security. A university may be intellectually formidable while remaining physically vulnerable.
The age of conquest: when military capability determined survival
The period associated with Nalanda’s decline was marked by political upheaval and military expansion. In such an environment, conquest could change the fate of a place in days; intellectual traditions often took generations to build.
The conventional historical account associates the destruction of important Buddhist institutions in Bihar with the campaigns of Bakhtiyar Khalji around the turn of the thirteenth century. But historical care matters. Minhaj-i-Siraj’s Tabaqat-i-Nasiri describes the capture of a place identified as Bihar; the relevant passage does not unambiguously name Nalanda or provide a detailed eyewitness account of the famous library burning as it is popularly retold today.
The broad association between conquest and Nalanda’s decline is well established in the historical tradition. The precise sequence of events, the extent of the destruction, and the intentions of those responsible are harder to establish with the same confidence. The familiar claim that the library burned for months should not be presented as a detail securely proven by a contemporary record.

An AI-generated artistic interpretation of an assault on a great centre of learning. It is not an eyewitness depiction, and the exact events and motives remain subjects for historical scrutiny.
Two opposing visions: the scholar and the conqueror
I believe Nalanda’s fate can be read as a collision between two very different measures of value. One vision invests in reflection, restraint, learning and the slow accumulation of understanding. The other, in its most destructive form, measures success through territory seized, wealth acquired and rivals subdued.
Nalanda’s Buddhist intellectual environment placed considerable emphasis on non-violence, ethical discipline and the examination of thought. The political world around it, however, was shaped by kingdoms, armies and contests for power. This contrast is illuminating, but it should not be simplified into a claim that every Buddhist was opposed to force or that every conqueror acted from a single religious motive. History rarely offers such neat divisions.
Nor should we assume that the institution was destroyed solely because its philosophy was peaceful, or that its destruction was necessarily a deliberate attempt to erase an opposing worldview. Religious hostility may have played a role in the treatment of Buddhist institutions, but the available evidence does not establish one definitive motive for every act associated with Nalanda’s end.
What can be said with greater confidence is that a community devoted to learning was exposed to forces whose immediate objectives were not the preservation of scholarship. When the power to destroy is concentrated in an army and the power to create rests on generations of teachers and students, the two sides are profoundly unequal.
What was the “official reason” for its destruction?
There is no known surviving official order or contemporary incident report that sets out a formal reason for the destruction of Nalanda. We should therefore distinguish between the broader historical account and a documented statement of motive.
The conventional explanation connects the damage to military conquest in Bihar under Bakhtiyar Khalji. Accounts and later retellings also emphasise the Buddhist character of the institutions affected. But the absence of a precise contemporary record naming Nalanda and explaining the decision means that claims about a single official reason—or a fully documented plan to destroy its knowledge—go beyond what the evidence securely demonstrates.
The responsible conclusion is not that nothing can be known. It is that the broad historical context is clearer than the exact chain of events and the intentions behind them.
What was lost when a centre of learning was attacked?
The destruction of a university is not measured only in burnt timber, damaged walls or lost buildings. It can mean the dispersal of teachers, the interruption of lineages of instruction, the loss of manuscripts, the collapse of patronage networks and the disappearance of knowledge that was never copied elsewhere.
The loss is especially severe when knowledge exists in fragile physical forms and is concentrated in one institution. A manuscript can be copied, but only if another copy survives. A teacher can train successors, but only if students and teachers are allowed to continue their work. An institution can rebuild, but its intellectual continuity may already have been broken.
This is the asymmetry between creation and destruction: scholarship accumulates slowly; violence can undo its conditions in a short time. The destruction of Nalanda therefore stands as both a historical tragedy and a warning about the vulnerability of institutions that preserve a society’s memory.
From Nalanda to modern law: the duty to protect learning
The modern world has gradually recognised that cultural and educational institutions are not ordinary spoils of war. The Hague Regulations of 1899 and 1907 included protections for institutions dedicated to religion, art, science and charitable purposes, as well as historic monuments. The 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict established a more specific international framework for safeguarding cultural property during conflict.
International humanitarian law also calls for special care to avoid damage to buildings dedicated to education, religion, art, science and charitable purposes, and to historic monuments, unless they are military objectives. These protections do not make destruction impossible. Their effectiveness depends on compliance, accountability, military judgement and the practical ability to protect sites during conflict.
The principle is nonetheless important: the fact that an institution belongs to a defeated society does not make its destruction morally neutral. A library, university, monastery, museum or archive holds value that extends beyond the immediate political fortunes of its custodians.
The lesson for India and the world
Nalanda should not be reduced to a slogan about one civilisation or one faith. Its story is more demanding than that. It asks whether societies can recognise the value of knowledge even when it belongs to people they oppose.
Military capability and intellectual excellence are not natural enemies. A capable state needs education, science, history, strategic thought and the ability to understand other societies. The danger arises when power loses sight of what must be preserved—when conquest becomes an end in itself and the institutions that make civilisation possible are treated as expendable.
The modern obligation to protect heritage during war is, in part, an acknowledgement that humanity’s inheritance cannot be owned entirely by the victor. The protection of a university or archive is not a favour to the defeated. It is a responsibility to future generations, who may need the knowledge, evidence and cultural memory those places contain.

The ruins still speak
The ruins of Nalanda are not merely the remains of a vanished institution. They are evidence of what human beings can build when they invest in learning, and of how vulnerable that achievement can be when political power is indifferent to its value.
We cannot reconstruct every detail of Nalanda’s destruction with certainty. We can, however, take its larger lesson seriously. The measure of power is not simply its capacity to prevail over an adversary. It is also its capacity to exercise restraint, protect what is irreplaceable and recognise that knowledge belongs to a future larger than the conflict of the present.
The enduring measure of a civilisation is not simply how much power it can command, but how much of humanity’s inheritance it is prepared to protect.
