Early Buddhist History

When the Buddha died he left no successor, no written scripture, and no central authority — only a community, a body of memorised teaching, and a disciplinary code. That the movement survived at all is not obvious. That it became, within three centuries, the beneficiary of imperial patronage across most of the Indian subcontinent is remarkable.

This guide covers the Indian phase: roughly the fifth century BCE to the thirteenth century CE, from the First Council to the point at which Buddhism effectively ceased to exist in the land where it began.

The problem the community faced #

The Buddha’s final instruction was that the Dhamma and the Vinaya would be the teacher after him. This solved one problem and created another. It prevented the emergence of a papacy, which the tradition seems to have regarded as a feature rather than a bug. But it meant that the content of the Dhamma and the Vinaya had to be fixed, agreed, and transmitted accurately by an organisation with no mechanism for settling disputes except consensus.

The result was a recurring pattern: recitation, agreement, drift, disagreement, and — when disagreement could not be resolved — separation. The councils are the visible points in that cycle, and the eighteen schools are its outcome.

Crucially, separation in this system is not heresy. The technical term is sanghabheda, a formal breach in communal ritual life, and what it usually meant in practice was that two groups stopped performing the fortnightly uposatha ceremony together. Schools that disagreed profoundly about Abhidharma still recognised one another as Buddhist, and their monks frequently lived in the same monasteries.

The councils #

Three or four councils are traditionally recognised, though the lists vary by school.

The First Council, at Rajagaha in the rainy season after the Buddha’s death, is said to have assembled five hundred arahants under Mahakassapa to recite the discourses (Ananda reciting) and the discipline (Upali reciting). The Second Council, at Vesali about a century later, addressed ten disputed points of monastic practice — the famous one concerns whether monks may accept gold and silver — and is generally accepted as broadly historical. The Third Council, at Pataliputra under Ashoka, is recognised by the Theravada tradition and not by others, which is itself a useful illustration of how the accounts are shaped by the schools that preserved them.

A Fourth Council appears in two different places: in Kashmir under Kanishka, associated with the Sarvastivada and the compilation of the Mahavibhasa; and in Sri Lanka in the first century BCE, when the Pali Canon was committed to writing.

Details are in The Buddhist Councils.

Ashoka and the transformation of scale #

The single most consequential event in Buddhist institutional history is the patronage of Ashoka Maurya, who ruled most of the subcontinent from roughly 268 to 232 BCE. His edicts, carved on rocks and pillars across his empire, are the earliest decipherable Indian writing and the first contemporary evidence for Buddhism of any kind.

What Ashoka actually did — and how Buddhist the dhamma of his edicts really is — is discussed in Emperor Ashoka and Buddhism. What is not in doubt is the effect. Under and after Ashoka, Buddhism went from a regional renunciant movement to a supra-regional institution with royal endowments, missions to Sri Lanka and the Hellenistic world, and a model of Buddhist kingship that later rulers from Sri Lanka to Japan would invoke.

The schools #

By the time of the Common Era the tradition had divided into a set of schools conventionally numbered at eighteen, though the lists disagree and the real number is higher. The primary early split was between the Sthaviravada (“elders”) and the Mahasamghika (“great assembly”), traditionally traced to the Second Council, though the sources conflict about the cause — a Vinaya dispute in one account, a doctrinal dispute about the status of the arahant in another.

From the Sthaviravada line came the Sarvastivada, dominant in the north-west and enormously productive in Abhidharma; the Theravada, which took hold in Sri Lanka and is the only early school surviving today as an independent tradition; and others including the Pudgalavada, which held the awkward and much-attacked position that there is a “person” that is neither identical to nor different from the aggregates.

Details, and the reasons for treating the number eighteen with caution, are in The Early Buddhist Schools.

The rise of the Mahayana #

Somewhere around the first century BCE a new body of literature began to appear — sutras presented as discourses of the Buddha, teaching a path to full buddhahood for the sake of all beings rather than to individual arahantship, and centred on the bodhisattva and, in the Prajnaparamita material, on emptiness.

Older accounts described this as a lay-led reform movement reacting against monastic scholasticism. That view has been substantially revised. Inscriptional evidence, analysed above all by Gregory Schopen, shows Mahayana as a minority monastic movement for centuries, invisible in the epigraphic record until quite late, and not institutionally separate: Mahayana monks were ordained in the same Vinaya lineages as everyone else and lived alongside monks who did not accept the new sutras.

The philosophical systematisation followed the literature rather than preceding it. Nagarjuna, probably second century CE, gave the Prajnaparamita material a rigorous dialectical form; Asanga and Vasubandhu, fourth or fifth century, built the Yogacara analysis of consciousness. See Mahayana Buddhism for the tradition as it exists now.

The great monasteries #

From roughly the fifth century, Indian Buddhism concentrated itself in large endowed monastic universities — Nalanda, Vikramashila, Odantapuri, Somapura, Valabhi. These were institutions of real scale: Xuanzang, who studied at Nalanda in the seventh century, describes thousands of resident monks, a curriculum covering Buddhist and non-Buddhist subjects, and a competitive admissions process.

They produced the late Indian scholastic tradition that Tibet would import wholesale — the logic of Dignaga and Dharmakirti, the Madhyamaka of Chandrakirti and Shantideva, and the tantric material that became Vajrayana. They also concentrated the tradition’s intellectual life, its libraries, and its wealth in a small number of physical locations, which proved to matter.

The decline #

By 1300 Buddhism had effectively disappeared from the Indian mainland. The standard popular explanation — destruction by Turkic invaders, with the sack of Nalanda around 1200 as the emblem — is part of the story and not the whole of it. Buddhism was already much reduced, and Hinduism and Jainism survived the same invasions.

Contributing factors usually discussed include the loss of royal patronage as dynasties reoriented towards Shaivism and Vaishnavism; the absorption of distinctively Buddhist elements into a broadening Hindu synthesis, with the Buddha eventually appearing as an avatara of Vishnu; the concentration of the tradition in large monasteries dependent on endowments rather than in a dispersed village presence; and the absence of the lay ritual functions — birth, marriage, death — that kept brahmins embedded in ordinary social life. See The Decline of Buddhism in India.

Buddhism returned to India only in the twentieth century, through the Tibetan diaspora and through Ambedkar’s mass conversion movement.

How the texts were transmitted #

Nothing in this period is intelligible without understanding that Buddhist scripture was, for its first several centuries, an oral literature maintained by specialists.

The method was not memorisation by individuals but organised communal recitation. Groups of monks called bhanakas specialised in particular collections — the Dighabhanakas in the long discourses, the Majjhimabhanakas in the middle-length ones — and recited them in unison at regular intervals. Unison recitation is a powerful error-correcting mechanism: an individual’s slip is audible against the group and does not propagate.

The texts themselves are built for the job. They are heavily formulaic, with stock phrases, numbered lists, and long verbatim repetitions that modern readers find tedious and that are in fact the redundancy that made accurate transmission possible. The Anguttara Nikaya, organised by numbers, and the Samyutta Nikaya, organised by topic, are as much retrieval systems as literary collections.

Writing was available — the Ashokan inscriptions prove it for the third century BCE — but was used for administration and proclamation rather than for scripture. The Pali Canon was reportedly first written down in Sri Lanka in the first century BCE, at Aluvihara, during a period of famine and war when the chain of reciters was thought to be at risk. Other schools wrote their canons down at other times, in Sanskrit or in intermediate dialects.

Two consequences matter for reading the material. First, the oral period explains both the reliability of the core and the impossibility of pinning down individual passages: the system preserved formulae extremely well and had no way of dating them. Second, the existence of parallel collections in Pali and in Chinese translation from now-lost Sanskrit originals gives historians a genuine comparative tool, since agreements between independently transmitted versions push material back before the schools separated.

The archaeological picture #

Texts describe an ideal. Inscriptions and excavations describe what people actually did with their money, and the two do not always match.

The epigraphic record from the earliest surviving sites — Sanchi, Bharhut, Amaravati — consists overwhelmingly of donative inscriptions: someone paid for this railing pillar, this coping stone, this slab. The donors include a great many monks and nuns, which is awkward for a textual picture in which monastics own nothing, and a great many women. The stated purpose is frequently the transfer of merit to deceased parents.

What is largely absent is meditation. The archaeological Buddhism of the early centuries is a religion of stupas, relics, pilgrimage, donation, and merit, organised around the veneration of the Buddha’s physical remains. This is not evidence that meditation was not practised; it is evidence that the tradition’s centre of gravity, for most participants most of the time, lay elsewhere. Schopen’s work made this point unavoidable, and it remains the strongest corrective to reading Indian Buddhist history out of the doctrinal literature alone.
