Langdarma, the Tibetan Empire's last unified-era king, reigned from 841 to 842 CE. Traditional Tibetan Buddhist historiography holds that he curtailed and destroyed the empire's Nyingma monasteries, then the only school of Tibetan Buddhism, ending the imperial patronage that had built Samye and secured the tradition's earlier establishment under Trisong Detsen. He was assassinated in 842, by most accounts by the monk Lhalung Pelgyi Dorje, an act later monastic tradition treats as the justified killing of a tyrant rather than a crime. The Tibetan Empire itself collapsed within years of his death, opening the two-centuries-long era of fragmentation with no single central Tibetan authority.
Facts
Disputed
Start YearSourced to the subject's own account841 is the reign start most commonly cited; some accounts give Langdarma a reign of six years and others thirteen, since the two chronicle traditions this figure is drawn from carry his own reign length differently, one more sympathetic to Buddhism than the other. End YearSourced to the subject's own account842 is the year most commonly given for the assassination, though some sources place it as late as 846. More consequentially, the persecution itself is a live scholarly dispute rather than settled history: the traditional account, widespread destruction of Buddhist monasteries and persecution of monks and nuns, is well documented in primary and secondary Tibetan sources, but the historian Zuiho Yamaguchi published "The Fiction of King Dar ma's Persecution of Buddhism," arguing that later chronicles were written within a pro-Buddhist monastic tradition with an interest in amplifying religious persecution over what may have been fiscal or administrative reforms curbing monastic subsidies. This atlas records the traditional account, since it is what the tradition's own later diffusion narrative responds to, and names the dispute against it here rather than presenting the persecution as settled fact.

How Langdarma's Reign Ended Imperial Patronage of Buddhism in Tibet
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Langdarma, the Tibetan Empire's last ruler of its unified era, reigned only briefly, from 841 to 842 CE, yet traditional Tibetan Buddhist historiography credits his short rule with ending a chapter of the tradition's history that had lasted more than a century. Where his predecessor Trisong Detsen had built Samye, Tibet's first monastery, and secured Buddhism's earlier establishment under direct imperial patronage, Langdarma is remembered as the king who curtailed and destroyed the empire's Nyingma monasteries, at that time the only school of Tibetan Buddhism in existence.
His reign ended in assassination in 842, an act most accounts attribute to the monk Lhalung Pelgyi Dorje. Later Tibetan monastic tradition did not remember the killing as a crime; it treated it instead as the justified removal of a tyrant who had turned the crown against the faith it had once sponsored. The Tibetan Empire itself did not survive Langdarma's death by more than a few years, collapsing soon after into a period of political fragmentation that lasted roughly two centuries, with no single central Tibetan authority left standing.
What Langdarma's reign changed for Buddhism's spread in Tibet was rupture: imperial patronage that had built monasteries and secured the tradition gave way, within one short reign, to persecution and then to the collapse of the empire that had sponsored either course.
