The 10 bloodthirsty struggles of the Tibetan Empire reveal a saga of ruthless ambition, shifting alliances, and spectacular conquests that shattered the myth of a peaceful, passive Tibet. From its humble beginnings in fragmented fiefdoms to a sprawling empire that even threatened the Tang capital, each chapter is a vivid tableau of power, intrigue, and bloodshed.
10 Foundation Of Imperial Power
In the seventh century, the Tibetan plateau resembled a patchwork of petty fiefdoms, each ruled by a local chieftain known as a gyelpo. During this era, Buddhist ideas began to displace older Hindu influences, while Chinese scientific and technological knowledge seeped in for the first time. One by one, these independent territories fell under the growing sway of the Yarlung Kingdom, laying the groundwork for what would become the Tibetan Empire. This unification was spearheaded by the dynamic warlord Namri Songtsen, who operated from a base near Mount Yarlha Shampo on the Bhutan border. He systematically forced neighboring tribes into submission, forging the nucleus of a centralized state.
Namri Songtsen met his end around 620 (sources vary between 618 and 627) through assassination. His death ignited a courtwide insurrection that loyal advisor Myang managed to quell. Yet a treacherous upstart named Zutse implicated Myang in a conspiracy, resulting in Myang’s death when his stronghold was stormed. Zutse then attempted to assassinate Prince Songtsen Gampo, the heir to the throne, but failed and took his own life. In a dramatic gesture, Zutse’s son presented his father’s severed head to Songtsen Gampo, proving his loyalty and securing his family’s fiefdom. Later, Songtsen Gampo’s younger brother attempted to claim the throne but perished in a fire allegedly set by a servant.
9 Destruction Of Zhang Zhung
In Upper Tibet’s western reaches lay the sophisticated kingdom of Zhang Zhung, the cradle of the pre‑Buddhist Bon religion. Bon, a shamanic faith with ties to Zoroastrianism and Hinduism, featured animal sacrifice and juniper burning. According to Bon tradition, Zhang Zhung was ruled by 18 kings—perhaps indicating several dynasties or a confederation of related realms. The kingdom may have used a divine script called “Mar,” meaning “coming from the sky,” though no original manuscripts survive; our knowledge stems from Tibetan conquerors’ chronicles.
At the time of Zhang Zhung’s demise, Limigya held power there, while Songtsen Gampo reigned over Tibet as Tsenpo, styling himself the “Divine Mighty One Magically Manifest.” Initially, Gampo pursued diplomatic ties, hoping to cement a dynastic alliance with Zhang Zhung. However, his sister Semarkar’s marriage to Limigya turned sour; she felt politically sidelined and refused to consummate the union. Her discontent was recorded in the Old Tibetan Chronicle, where she plotted to have her brother subdue her husband’s realm. An emissary was sent to persuade her to bear an heir, but she remained obstinate, prompting Tibetan forces to intervene.
When Semarkar’s poems reached Gampo, he recognized the political opportunity. He accepted her gift of 30 turquoise pieces, deciding to wear them as a man rather than as a woman’s adornment. Gampo then launched an invasion of Zhang Zhung, slaying Limigya and dismantling his power base. The capital, Khyunglung Ngulkhar, became a new administrative hub for central Tibet. The conquest of Zhang Zhung, alongside the highland kingdom of Sumpa, led to the creation of “tongde” administrative units, marking the first unification of the Tibetan plateau and providing the manpower and resources that propelled the empire’s rise.
8 Conquest Of The Tarim Basin
Songtsen Gampo’s grandson, Mangsong Mangtsen, extended Tibetan influence far beyond the plateau. He first subdued the ‘A zha (the Tuyuhun) from Mongolia, a tribe that had clashed with both the Tang dynasty and Tibet. Their leader Nuohebo fled to China, where the Tang resettled his remnants to keep them under control. With the Tuyuhun neutralized, Mangsong turned his gaze westward, pushing Tibetan power into the Tarim Basin—modern Xinjiang—and even reaching the Wakhan Valley of present‑day Afghanistan.
The Tang dynasty, alarmed by the loss of crucial Silk Road oasis cities, attempted to counter Tibet’s expansion. However, the Tibetans managed to subjugate the Western Turks by 670, securing loyalty from key trade hubs such as Kashgar and Khotan. The Tang dispatched a formidable army, only to be decisively beaten at Dafeichuan by General mGar Khri ’bring, leading to a Chinese withdrawal. During this period, the mGar clan (also known as the Gar clan) wielded considerable power behind the throne, with chief minister Gar Songtsan effectively controlling royal authority—a threat the monarchy later had to neutralize.
7 War Against The Clan
The mGar clan traced its roots to the Yuezhi people, having migrated southward after Xiongnu pressure and settling in Tibet around 190 BC. Their name, meaning “blacksmith,” hinted at modest origins, yet over five decades they produced several chief ministers and generals, becoming central to Tibetan expansion. However, their growing influence sparked suspicion. Thrimalo, wife of Mangsong Mangtsen and mother of the child‑king Tridu Songtsen, distrusted the clan. Tang ambassador Kuo Yuan‑chen further exploited these tensions, prompting the mGar to demand Chinese withdrawal from the Tarim Basin on the premise of local self‑rule.
Kuo engaged in diplomatic maneuvering, proposing an exchange: the Nu‑shih‑pi tribes for control over Koko Nor and the Tuyuhun. He believed that a peace settlement would weaken the mGar’s grip on Tibet. His calculations proved accurate; while mGar Khri ’bring triumphed over a larger Chinese force at the “Chinese Graveyard at Tiger Pass,” Tridu Songtsen seized the moment. Under the pretense of a hunting expedition, he arrested and executed over 2,000 mGar members. When Khri ’bring refused surrender, his troops abandoned him, and the general took his own life. Survivors either fled to China—receiving official posts—or perished. Tridu later married multiple regional princesses but died in a campaign against the Nanzhao kingdom in modern Yunnan.
6 Shifting Alliances In Central Asia
The Umayyad Caliphate’s incursion into Bactria in 663 introduced a new player to Central Asian politics. Initially, Buddhists there received dhimmi status—protection without forced conversion. In 680, an Iraqi rebellion distracted the Umayyads, allowing Tibet to ally with Turkmen forces in 705 to expel the Arabs. Though the first attempt faltered, Turkmen leader Nazaktar Khan seized the region in 708, imposing a fanatical Buddhist regime and even beheading a Muslim abbot.
When Arab general Qutaiba reclaimed Bactria, the Tibetans switched sides, aligning with the Umayyads. However, the Arabs demanded that all allies accept Islam, prompting Tibet to host missionary al‑Hanafi—though the court’s reception was icy, and conversion remained minimal. Later, the Tang pushed back, capturing territories from both the Umayyads and the Eastern Turks. The Tang forged an alliance with the Qarluqs, while the Turgesh allied with Tibet, pushing the Chinese further west. Yet, as the Turgesh confederation dissolved, Tibet leaned on its longstanding partnership with the Turki Shahis of Kabul, allowing the Arabs to reclaim some ground.
Interestingly, despite the religious divide—Muslims versus Buddhists—the period was driven more by realpolitik than faith. Alliances shifted, betrayals abounded, and the quest for strategic advantage eclipsed doctrinal concerns.
5 Occupation Of Chang’an
The An Lushan rebellion of 755 crippled the Tang dynasty, creating an opening for aggressive Tibetan officials to stage a coup against Emperor Tride Tsuktsan. They installed the 13‑year‑old Trisong Detsan as emperor, who immediately launched an expansionist campaign. With Chinese border garrisons withdrawn to quell internal unrest, Tibetan forces raided unhindered. In 763, two Tang envoys en route to Tibet were detained as the Tibetans prepared a massive invasion. The Tang emperor fled Chang’an, taking refuge in Shanzhou, while a defeated Chinese general led Tibetan troops straight into the imperial capital.
Although the Tibetans installed a puppet ruler—the uncle of a Chinese princess married into the Tibetan court—their hold on Chang’an lasted a mere 15 days. Tang General Guo Ziyi cleverly used fires and war drums to simulate a massive approaching army, prompting the Tibetans to retreat. Subsequent decades saw frequent skirmishes along the border, but large‑scale wars were scarce. Both sides struggled to control ambitious frontier generals, leading to a series of uneasy treaties and betrayals.
Records from Dunhuang, occupied by Tibet in 786, reveal that locals were forced to wear Tibetan attire except on special occasions when traditional Chinese dress was permitted. Tibetan officials notoriously kidnapped Chinese women for marriage, a practice eventually curtailed after widespread complaints. A new bureaucratic hierarchy emerged, placing low‑ranking Tibetan officials above high‑ranking Chinese ones. The city became a hub for translation and papermaking, with Chinese scribes producing thousands of Buddhist sutras under the threat of violence and property seizure.
4 A Short‑Lived Alliance
In 779, Tang Emperor Dezong ascended a dynasty beleaguered by internal revolts and external threats. Seeking to reduce reliance on the despised Uighurs, Dezong pursued an alliance with Tibet, hoping to stabilize the southern frontier. Tibetan diplomats returned with roughly 500 captives rescued from previous missions to Chang’an. However, the same year saw a Tibet‑Nanzhao assault on the Tang southeast, which the Chinese repelled.
Negotiations eventually produced a treaty establishing a permanent border. The Tang sought military assistance against rebel Zhu Ci, while Tibet demanded an annual stipend of 10,000 bolts of silk and cession of the western territories Anxi and Beiting. When negotiations stalled, a Tang envoy forged a letter implying Tibetan acceptance. Tibetan troops then aided the Tang, playing a decisive role in defeating Zhu Ci. Yet, they withdrew before the rebels retook the capital.
Dezong, eager to meet Tibetan demands, faced opposition from his ministers, who argued that maintaining a Chinese presence in the west was strategically vital. Consequently, he offered only silver, prompting enraged Tibetans to launch a sweeping invasion of northwestern China, seizing livestock and people. The Tang responded swiftly; dwindling supplies and a Tang counter‑invasion forced Tibetan forces to withdraw. Under the pretense of peace, Tibetans ambushed Tang envoys, murdering and kidnapping many. Ultimately, the Tang turned to the Uighurs and courted Nanzhao and the Arabs, hoping to encircle and neutralize Tibet.
3 War With The Abbasid Caliphate
The Abbasid Caliphate, succeeding the Umayyads in Central Asia, scored a decisive victory over the Tang at the 751 Battle of Talas River, aided by the Qarluq allies. Soon after, the Qarluqs embarked on their own expansion, seizing Suyab, Ferghana, and Kashgar. Turning against the Abbasids, they allied with Tibet, its vassals in Kabul, and the White‑Clad Oghuz. After Caliph al‑Rashid’s death in 808, a civil war erupted among his sons, culminating in al‑M’amun’s triumph in 813. Al‑M’amun declared a holy war against Tibet and its allies, possibly blaming them for his father’s demise and for supporting Abu Muslim rebels.
In 815, Abbasid forces captured Kabul, compelling its Turki Shahi ruler to convert to Islam and dispatch a golden Buddha statue to Mecca—a propaganda move suggesting the Tibetan ruler had embraced Islam. The statue was later melted down for coinage. Abbasids also reclaimed Ferghana from the Qarluqs and seized Gilgit from Tibet, sending a humbled Tibetan general to Baghdad as a captive.
Nevertheless, the Abbasids hesitated to press further, as local rulers in western Turkestan and eastern Iran asserted independence. While the Caliphate dealt with these internal challenges, Tibet and the Turki Shahis recaptured lost territories. Most of this conflict unfolded under Tibetan Emperor Sadnalegs, during which some Arab soldiers were captured and incorporated into Tibetan frontier garrisons, with a few possibly settling within central Tibet.
2 Reign Of Ralpacan
Emperor Ralpacan presided over the Tibetan Empire at its territorial zenith, controlling swaths of China, Nepal, India, Baltistan, Khotan, Gilgit, Zhang Zhung, and much of Gansu and Turkistan. Regarded as one of the last “dharma kings” (chos rgyal), he fortified Buddhism’s influence throughout the realm. Ralpacan also instituted administrative reforms that curbed noble power. A devout patron of Buddhism, he funded monasteries, stupas, and the translation of Sanskrit scriptures, yet remained a formidable warlord.
In 810, when the Tang emperor requested the return of three provinces, Ralpacan dispatched General Zhang ‘Bro Stag to wage war on both the Chinese and the Uighurs in the north. By 816, Zhang’s forces threatened the Uighur capital Ordu Baliq, and in 819 he assaulted the southern Chinese border city of Yanzhou. Another raid in 821 likely contributed to the first genuine peace treaty between Tibet and China, negotiated by Buddhist monks from both sides. The treaty talks convened at Gugu Meru, with stone pillars erected at Gugu Meru, Lhasa, and Chang’an, inscribing the agreement in both Tibetan and Chinese. The accord framed the Sino‑Tibetan relationship as that of “uncle and nephew.”
Despite diplomatic successes, Ralpacan’s heavy support for Buddhism alienated Bon adherents. He mandated that every seventh household support a Buddhist monk, elevating monks to a privileged class. At state functions, he famously tied long yellow ribbons in his hair, allowing monks to sit upon them. This provoked Bon supporters, who sought to replace him with his brother Lang Darma. While some accounts claim Ralpacan died of illness, others allege he was strangled by two anti‑Buddhist ministers.
1 Sectarian Violence And Imperial Collapse
Lang Darma’s brief reign marked a violent reversal of Ralpacan’s Buddhist policies and precipitated the empire’s downfall. The taxes Ralpacan imposed to sustain monasteries generated resentment among noble clans, exacerbated by successive poor harvests. Monasteries, exempt from taxation and military conscription, siphoned resources and manpower from the imperial apparatus, while the nobility’s lands gradually transferred to Buddhist abbots through gifts and inheritances.
According to one historian, Lang Darma commanded all Buddhist priests and Bon magicians to invoke every protective deity of the Land of Snows—a ritual believed to have birthed the modern Tibetan festival where oracles channel deities that feast and gamble for human souls. During the festival’s inaugural celebration, a bolt of lightning struck Samye Monastery, which Lang Darma interpreted as divine displeasure with Buddhism.
Lang Darma ordered the suppression of Buddhism: monasteries were closed, monks forced to convert or perish, temples destroyed, and foreign Buddhist teachers expelled. This systematic eradication left folk Buddhism as the surviving tradition, while Bon regained prominence. The conflict was as much political as religious; Lang Darma aimed to dismantle the monasteries’ destabilizing influence.
In 846, Lang Darma met a grisly end, assassinated by Buddhist monk Lhalhung Beigye Dorgye, who disguised himself as a Bon priest (or wore a robe black outside and white inside). After his death, a power struggle erupted between his sons Yumten and Oedsung, each backed by rival court factions. Tibet fractured into northern and southern halves, vassal states broke away, and central administration collapsed, returning the plateau to a mosaic of petty fiefdoms.
From the chaotic beginnings of fragmented tribes to a sprawling empire that dared to occupy the Tang capital, the 10 bloodthirsty struggles of the Tibetan Empire reveal a legacy of ambition, betrayal, and relentless warfare. Their story reminds us that history is rarely as tranquil as we sometimes imagine, and that even the most seemingly serene cultures can harbor fierce, war‑driven hearts.
