Peoples / fragmented polities · 842 – 1253
The unified Tibetan Empire collapsed with the assassination of its last king, Langdarma, in 842 — killed, by tradition, by the Buddhist hermit monk Pelgyi Dorje of Lhalung. His death left two rival heirs, Yumtän and Ösung, whose civil war (following the Battle of U-Yor) destroyed royal authority and dissolved the empire into tribes and small kingdoms.

Origins and founding
The unified Tibetan Empire collapsed with the assassination of its last king, Langdarma, in 842 — killed, by tradition, by the Buddhist hermit monk Pelgyi Dorje of Lhalung. His death left two rival heirs, Yumtän and Ösung, whose civil war (following the Battle of U-Yor) destroyed royal authority and dissolved the empire into tribes and small kingdoms.
Capitals and territory
There was no central authority between 842 and 1247. The successors of Ösung controlled western Ngari; the successors of Yumtän held central Ü. Ösung's grandson Thrikhyiding (Kyide Nyigön) migrated to upper Ngari and founded a dynasty that went on to create the kingdoms of Purang-Guge, Maryul (Ladakh) and Zanskar; other regional polities included Derge, Nangchen, Tsongkha and Mangyül. Regional warlords ruled from private fortresses and armies, returning Tibet to the pre-imperial pattern of local polities.
Major rulers and key events
Rather than emperors, the period is defined by regional dynasties — the Guge and Maryul kingdoms in the west, Tsongkha in Amdo, and the kingdoms of Kham. The era closed with the Mongol conquest of Tibet in the 1240s and the appointment of Drogön Chögyal Phagpa as Imperial Preceptor of the three regions of Tibet in 1253, inaugurating Yuan rule and Sakya patronage.
Government, economy and culture
Government was fragmented among petty kings and monastic leaders. Traditional accounts depict the era as a low point for Tibetan Buddhism, with the Nyingma school's monasteries driven into internal exile and surviving mainly in Amdo; the scholar Gongpa Rapsel (953–1035) revived the Nyingma tradition there, and his students re-propagated the lineages in Ü-Tsang — the "later diffusion" of Buddhism. Modern historians note that Buddhism remained widespread and that local rulers maintained close ties to monastic leaders. Tibetans of the plateau maintained their distinctive culture — Tibetan Buddhism and Bon religion, barley-and-tsampa cuisine, thangka painting, lhamo opera, and the medical tradition of Yuthog Yontan Gonpo's Four Medical Tantras.
Decline and end
The fragmentation ended not through internal reunification but through external conquest: the Mongols absorbed Tibet in the 1240s, and by 1253 the Sakya–Mongol priest-patron relationship had replaced the patchwork of kingdoms.
Legacy and significance
The Era of Fragmentation paradoxically laid the religious foundations of later Tibetan civilisation: the revival of Buddhism from Amdo, the rise of the western kingdoms (Guge became a great centre of Buddhist art and translation), and ultimately the theocratic institutions that culminated in the Ganden Phodrang state of the Dalai Lamas.

- When did the Tibetans exist?

- How large were the Tibetans?
- At their greatest extent drawn on this map, the Tibetans covered about 1.9 million km². That is the largest area the border data gives them across the years they are drawn, not necessarily their greatest extent in history.
- Where were the Tibetans?
- There was no central authority between 842 and 1247. The successors of Ösung controlled western Ngari; the successors of Yumtän held central Ü.
- Who ruled the Tibetans?
