Buddhism in Mongolia

• 1. Introduction

  ›

  Buddhism in Mongolia is the faith of more than half the country's population, a religion that has been adopted, suppressed, nearly destroyed, and reborn across nearly two thousand years. By the 2020 census, 51.7 percent of Mongolians identified as Buddhist. That number tells only the present. The more revealing story is how Buddhism arrived on the steppes not once, not twice, but three distinct times, and how each arrival reshaped the relationship between religion, political power, and the people who lived between them.

  The religion the Mongols eventually made their own draws from Vajrayana Tibetan Buddhism, particularly the Gelug and Kagyu lineages, but it is not simply Tibetan Buddhism transplanted onto colder soil. It developed its own character, its own institutions, and its own sacred figures. At one point in the early twentieth century, roughly one third of all Mongolian men were monks. That is the kind of number that stops you. It invites a question: how did a nomadic culture of herders and warriors come to center its entire social order on a monastic institution? And what happened when the modern world decided that institution had to go?

• 2. The Steppes Before Buddhism

  ›

  Before Buddhism took hold, Mongolian religious life turned on two forces: the sky and the dead. Traditionally, Mongolian ethnic religion centered on worship of Heaven, understood as the eternal blue sky, and on reverence for ancestors. Alongside these stood shamanism, the ancient practice of North Asia in which human intermediaries entered trance states to speak with the numberless spirits believed to govern human fortune and misfortune.

  This was not a passive faith. Shamans were active agents in the world: healers, diviners, negotiators with the spirit realm. Their presence was woven into every cycle of herding life. The arrival of Buddhism did not erase these traditions overnight. The two systems competed, borrowed from each other, and reached a kind of tense accommodation that shaped Mongolian religion for centuries. Buddhist monks would eventually take on the functions of shamans as healers and diviners, pressing the older tradition toward the margins. But the older tradition never fully disappeared, and its traces remained visible in the distinctly Mongolian character that Buddhism developed on the steppes.

• 3. The First Arrival

  ›

  Buddhism reached the Mongolian steppes as early as the 1st century CE, carried in from Central Asia along the pathways that nomadic empires kept open. The rulers of successive steppe powers, including the Xiongnu, the Xianbei, and the Rouran Khaganate, received Buddhist missionaries and built temples for them. The Xianbei-led Northern Wei dynasty, which lasted from 386 to 535 CE, became a notably strong patron of the faith.

  The language of these early encounters tells its own story. The oldest known Mongolian translations of Buddhist texts were rendered from Uyghur, not from Sanskrit or Tibetan directly, and they carry Turkic words embedded in their vocabulary: sümbür tay for Mount Sumeru, quvaray for monk. Buddhist ideas arrived pre-filtered through the culture of the Uyghur Khaganate, which had dominated the Mongolian steppes before the Khitan-led Liao dynasty rose in the 10th century. Even the Khitan aristocracy regarded Buddhism partly as a heritage of the Uyghurs who came before them. The faith traveled with empire, and it picked up the vocabulary of every people it passed through on its way north.

• 4. Kublai Khan and the Sakya Alliance

  ›

  Genghis Khan, born around 1162 and died in 1227, conquered territories stretching from the Pacific to Eastern Europe, but it was his grandson Kublai Khan who made Buddhism the defining institution of the Mongol state. Kublai founded the Yuan dynasty in 1271 and invited the lama Drogon Chogyal Phagpa of the Sakya school of Tibetan Buddhism to carry the faith throughout his realm.

  The relationship between Kublai and Phagpa produced consequences that outlasted both men. In 1269, Kublai commissioned Phagpa to design a new writing system capable of expressing Mongolian, Tibetan, Chinese, Uyghur, and Sanskrit in a single unified script. The result, known as the Phags-pa script or Square script, was built on the Tibetan alphabet and written vertically. It became the official script of the empire.

  Buddhism under the Yuan was not a purely Mongol affair. The Mongols' imperial reach brought them into contact with Nestorian Christian communities of the Church of the East, and some Mongolian Buddhist institutions absorbed significant amounts of Nestorian doctrine. Manichaeism, Islam, Zoroastrianism, and even Roman Catholicism left traces in the syncretic religious landscape of the period. Buddhism became the de facto state religion, but the state it served was one of the most religiously mixed in world history.

• 5. Altan Khan and the Dalai Lama Title

  ›

  After the Yuan dynasty collapsed in 1368, the Mongols largely returned to shamanic practices. The third introduction of Buddhism came in the 16th century, and it began with a meeting that changed the religious vocabulary of Asia. In 1578, Altan Khan, a Mongol military leader who wanted to unite the Mongols and saw himself in the mold of Genghis Khan, invited the head of the rising Gelug lineage to a summit.

  The man he invited was Sonam Gyatso, and the title Altan Khan gave him at that meeting was Dalai Lama, meaning Ocean Lama. Sonam Gyatso became the third holder of that title retroactively, since his two previous reincarnations were counted back. In exchange, Sonam Gyatso recognized Altan Khan as a reincarnation of Kublai Khan, lending the Mongol leader the prestige of the great Yuan founder. Altan Khan also gave Sonam Gyatso the title Ochirdara, drawn from the Sanskrit Vajradhara. Each man gave the other what he most needed: one received religious legitimacy, the other received political protection.

  Altan Khan died soon after the summit, but the alliance he forged continued to bear fruit. Over the following century, the Gelug school spread across Mongolia, helped along by competing Mongol aristocrats who each sought religious sanction for their own political ambitions. Monasteries called viharas, known in Mongolian as datsan, went up at the junctions of trade routes and seasonal pastures, positioned to catch the large gatherings of herders that had once assembled for shamanistic rituals.

• 6. The Monastery State

  ›

  By the start of the twentieth century, Outer Mongolia held 583 monasteries and temple complexes, and these institutions controlled an estimated 20 percent of the country's wealth. Ulaanbaatar, then known as Ikh Huree, meaning Big Monastery, had grown up around its religious center. The city's largest two monasteries housed approximately 13,000 and 7,000 monks respectively.

  The 8th Jebtsundamba Khutuktu, also called the Bogdo Gegen and later the Bogd Khan, presided from Ikh Huree as the preeminent living Buddha of Mongolia, ranking third in the ecclesiastical hierarchy behind only the Dalai Lama and the Panchen Lama. Across the country, a total of 140 living Buddhas held both religious and, in many areas, secular authority. In the 1920s, about 110,000 monks, including children, made up roughly one third of the male population, though many lived outside the monasteries and did not observe their vows strictly.

  The monasteries had accumulated their wealth and power gradually as the influence of the Mongol nobility declined. Some nobles donated families of dependent people to the monasteries, since in old Mongolia people rather than land were the foundation of power. Some herders attached themselves to monasteries voluntarily, seeking shelter from the arbitrary demands of the nobility. When Manchu rule ended in 1911, the Buddhist church provided the only organized political structure in existence. The autonomous state that followed took the form of a theocracy, weakly centralized and headed by the Jebtsundamba Khutukhtu in Yehe Kuriye.

• 7. Suppression and Survival

  ›

  When the Mongolian People's Republic took power, the new rulers inherited a country whose religious institution rivaled the state itself. As late as 1934, the party counted 843 major Buddhist centers, roughly 3,000 temples of various sizes, and about 6,000 associated buildings. The church's annual income was 31 million tögrögs; the state's was 37.5 million. A party source claimed that by 1935, monks made up 48 percent of the adult male population.

  Robert Rupen recorded that in the 1920s more than 112,000 Mongolian Buddhist monks represented over 13 percent of Mongolia's total population. The campaign to dismantle the church proceeded through conciliation and persecution in alternating waves, with reported uprisings led by monks and abbots along the way. By the 1940s, nearly every monk was either dead or had abandoned his vows.

  In 1938, with accusations circulating that the church was cooperating with Japan's effort to create a pan-Mongol puppet state, the remaining monasteries were dissolved, their property seized, and their monks secularized, interned, or executed. Monastery buildings that survived destruction were repurposed as government offices or schools. Only after this was the party able to direct the country's wealth toward its modernization program.

  One institution was permitted to survive in a limited form: Gandan Monastery in Ulaanbaatar, maintained with a community of 100 monks. Foreign policy rather than faith kept it open. Ulaanbaatar served as the headquarters of the Asian Buddhist Conference for Peace, which organized conferences drawing Buddhists from Japan, Vietnam, Cambodia, Sri Lanka, and Bhutan, and which sponsored the Dalai Lama's visits to Mongolia in 1979 and 1982. A few aged former monks were employed to translate Tibetan-language texts on traditional medicine. The party concluded that total erasure of Buddhist knowledge would sever modern Mongols from too much of their own past.

• 8. Renewal After 1990

  ›

  After the overthrow of communism in 1990, roughly 200 temples returned to operation, and a monastic community of between 300 and 500 monks and nuns began to reconstitute itself. Vesna Wallace, a professor of religious studies at UC Santa Barbara, observed that more people were coming to temples and visiting monasteries, and that a new interest in meditation had emerged among the general public.

  Gandan Monastery, once kept open mainly for international display, was reinvigorated by the post-communist government and renamed Gandantegchinlen Monastery. The 2010 national census found that 53 percent of Mongolians identified as Buddhist. A decade later, the 2020 census recorded 51.7 percent, while the Association of Religion Data Archives put the figure at 58.1 percent. The variation in those numbers reflects genuine complexity: a population that survived the near-total destruction of its religious institutions, and that has been rebuilding them for three decades, in a country where shamanism still lives alongside the temples and the question of what it means to be a Mongolian Buddhist is still being answered.
