Destruction of Nalanda

Background

Nalanda Mahavihara was a monastic university in ancient Magadha, near present-day Rajgir in Bihar, that for roughly seven centuries was among the largest centers of Buddhist learning in the world. Tradition credits its founding to the Gupta emperor Kumaragupta I in the 5th century CE, though the site had earlier associations with the Buddha and with Mahavira. It grew through continued patronage from later Gupta rulers, from Harshavardhana of Kannauj in the 7th century, and especially from the Pala dynasty of Bengal and Bihar (roughly 8th to 12th century CE), under whom it reached its greatest size and international reputation, alongside sister institutions such as Vikramashila and Odantapuri.

The University

At its height, Nalanda combined a monastery (vihara) with a residential university, teaching Mahayana Buddhist philosophy — including the Yogachara and Madhyamaka schools — alongside logic, grammar, medicine, and astronomy, and drew both monastic and lay scholars. The Chinese pilgrim-monk Xuanzang, who studied there in the 630s CE under the abbot Silabhadra and later wrote an account of his travels, describes a walled complex of towering multi-storied halls and thousands of resident monks and students. A second Chinese pilgrim, Yijing, studied at Nalanda in the 670s-680s CE and left his own account of its curriculum and monastic discipline. Nalanda's library complex, known as Dharmaganja ("Treasury of Truth"), comprised three multi-storied buildings — the Ratnasagara, Ratnadadhi, and Ratnaranjaka — housing an extensive collection of manuscripts on Buddhist and secular subjects, drawn on by students who traveled from as far as Tibet, China, Korea, and Southeast Asia.

The Attack

In the final years of the 12th century, Turkic forces under Ghurid command advanced into Bihar and Bengal as part of the broader campaign that established Muslim rule in northern India. The sack of Nalanda is conventionally dated to 1193 CE and attributed to Ikhtiyar al-Din Muhammad Bakhtiyar Khalji, a commander of the Khalji clan serving under the Ghurid sultan Muhammad of Ghor, who was subsequently granted control of conquered territory in Bihar and Bengal. The principal historical source for the episode is the Tabaqat-i-Nasiri, a Persian chronicle completed around 1260 CE by Minhaj-i-Siraj Juzjani, who reports that Bakhtiyar's forces stormed a fortified monastery in Bihar, killing the shaven-headed monks inside in the belief that they had captured a garrison of armed men, and that the manuscripts housed there were burned. Later Tibetan Buddhist historiography, notably Taranatha's early 17th-century History of Buddhism in India, corroborates the general episode, describing the destruction of monastic centers in Magadha during this period, though it was compiled centuries after the events it describes.

Historiographical Notes

Historians differ on some particulars. Minhaj's account describes the sack of a fortified religious complex in Bihar without naming Nalanda explicitly, and some scholars identify the specific structure he describes with the nearby monastery of Odantapuri rather than Nalanda itself; the two are frequently conflated in popular retellings. Archaeological evidence — a layer of ash and burned manuscript fragments recovered during 20th-century excavation of the Nalanda site — is consistent with violent destruction by fire in this general period, though dating such evidence precisely to a single year is difficult. Some historians, drawing on Tibetan and Buddhist sources, have argued that Nalanda's monastic population and royal patronage were already contracting before the Ghurid incursions, as Buddhism's institutional base in eastern India weakened relative to resurgent Brahmanical and Vaishnava traditions, and that the 1193 raid accelerated rather than single-handedly caused the university's end. What is not disputed is that organized monastic education at Nalanda did not resume after this period, and that many surviving monks and manuscripts relocated to Tibet, Nepal, and other Buddhist regions of the Himalayas and Southeast Asia.

Aftermath and Legacy

The end of Nalanda coincided with, and is generally treated by historians as one factor in, the broader decline of institutional Buddhism in the Indian subcontinent during the 12th and 13th centuries, a process also driven by the earlier absorption of Buddhist devotional practice into Puranic Hinduism and by the loss of royal patronage as Buddhist-favoring dynasties gave way to others. The ruins of Nalanda were surveyed by the British archaeologist Alexander Cunningham in the mid-19th century and more fully excavated by the Archaeological Survey of India between 1915 and 1937, revealing a complex of monastery courts, stupas, and temples across a site of some twelve hectares. The ruins were inscribed as a UNESCO World Heritage Site in 2016. In 2010, the Indian Parliament passed an act establishing a new, internationally sponsored Nalanda University a short distance from the ancient site, conceived as a revival of the region's tradition of higher learning.
