According to the local Mon and Burman traditions, this is Suvarnabhumi, the area visited by missionaries from the Ashokan court. It is known that Buddhist kingdoms had appeared in this region by the early centuries of the 1st millennium ce. In Myanmar and Thailand, despite the presence of Hindu, Mahayana, and Vajrayana elements, the more-conservative Hinayana forms of Buddhism were especially prominent throughout the 1st millennium ce. Farther to the east and south, in what is now Cambodia and southern Vietnam, various combinations of Hinduism, Mahayana Buddhism, and Vajrayana Buddhism became prevalent. Throughout much of the history of Angkor, the great imperial centre that ruled Cambodia and much of the surrounding areas for many centuries, Hinduism seems to have been the preferred tradition, at least among the elite. In the late 12th and early 13th centuries, however, the Buddhist King Jayavarman VII built a new capital called Angkor Thom that was dominated by both Mahayana and Vajrayana monuments, which represent one of the high points of Buddhist architecture.
In mainland Southeast Asia, as in Sri Lanka, a Theravada reform movement emerged in the 11th century. Drawing heavily on the Theravada heritage that had been preserved among the Mon in southern Myanmar, as well as on the new reform tradition of Sri Lanka, this revival soon established the Theravada tradition as the most dynamic in Myanmar, where the Burmans had conquered the Mon. By the late 13th century, the movement had spread to Thailand, where the Thai were gradually displacing the Mon as the dominant population. During the next two centuries, Theravada reforms penetrated as far as Cambodia and Laos.
The preeminence of Theravada Buddhism continued throughout the area during the remainder of the premodern period. The arrival of the Western powers in the 19th century brought important changes. In Thailand, which retained its independence, a process of gradual reform and modernization was led by a new Buddhist sect, the Thammayut Nikaya, which was established and supported by the reigning Chakri dynasty. In the 20th century reform and modernization became more diversified and affected virtually all segments of the Thai Buddhist community.
Two late 20th-century Buddhist groups, Santi Asoke (founded 1975) and Dhammakaya, are especially interesting. Santi Asoke, a lay-oriented group that advocates stringent discipline, moral rectitude, and political reform, has been very much at odds with the established ecclesiastical hierarchy. The Dhammakaya group has been much more successful at gathering a large popular following but has also become very controversial because of its distinctive meditation practices and questions concerning its care of financial contributions from its followers.
In the other Theravada countries in Southeast Asia, Buddhism has had a much more difficult time. In Myanmar, which endured an extended period of British rule, the sangha and the structures of Buddhist society have been seriously disrupted. Under the military regime of General Ne Win, established in 1962, reform and modernization were limited in all areas of national life, including religion. With the suppression of the pro-democracy movement in the late 1980s, the country’s military rulers used their support of a very traditional form of Buddhism to legitimize their highly repressive regime. Nevertheless, in the second decade of the 21st century, both government restrictions on opposition leader Aung San Suu Kyi and rules regarding political participation were eased, and the future of Buddhism seemed destined for change. In Laos and Cambodia, both of which suffered an extended period of French rule followed by devastation during the Vietnam War and the violent imposition of communist rule, the Buddhist community has been severely crippled. Beginning in the 1980s, however, it showed increasing signs of life and vitality. In Laos it was recognized by the government as a part of the national heritage, and in Cambodia it was even given the status of a state religion. Vietnam
There are indications that Vietnam was involved in the early sea trade between India, Southeast Asia, and China, and it is quite probable that Buddhism reached the country via this sea route near the beginning of the 1st millennium ce. The northern part of what is now Vietnam had been conquered by the Chinese empire in 111 bce and remained under Chinese rule until 939 ce. Hinayana and Mahayana traditions spread into the two Indianized states, Funan (founded during the 1st century ce) and Champa (founded 192 ce). The long-term development of Buddhism in Vietnam, however, was most affected by Zen and Pure Land traditions, which were introduced from China into the northern and central sections of the country beginning in the 6th century ce.
The first dhyana (Zen; Vietnamese thien), or meditation, school was introduced by Vinitaruchi (Vinitaruci), an Indian monk who had gone to Vietnam from China in the 6th century. In the 9th century a school of “wall meditation” was introduced by the Chinese monk Vo Ngon Thong. A third major Zen school was established in the 11th century by the Chinese monk Thao Durong. From 1414 to 1428 Buddhism in Vietnam was persecuted by the Chinese, who had again conquered the country. Tantrism, Daoism, and Confucianism also filtered into Vietnam at this time. Even after the Chinese had been driven back, a Chinese-like bureaucracy closely supervised the Vietnamese monasteries. The clergy was divided between those who were highborn and Sinicized and those in the lower ranks who often were active in peasant uprisings.
During the modern period Mahayana traditions in northern and central Vietnam have coexisted with Theravada traditions from Cambodia in the south. Rather loosely joined together, Vietnamese Buddhists managed to preserve their traditions through the period of French colonial rule in the 19th and 20th centuries. During the struggle between North and South Vietnam in the 1960s and early ’70s, many Buddhists worked to achieve peace and reconciliation, though they met with little success; to protest the South Vietnamese regime of Ngo Dinh Diem, some Buddhist monks turned to self-immolation. Under the communist regime that has ruled the reunited country since 1975, conditions have been difficult, but Buddhism has persisted. Reports since the late 1980s indicated signs of vitality despite serious government limitations on Buddhist activities. Central Asia and China Central Asia
The spread of Buddhism into Central Asia is still not completely understood. However murky the details may be, it is clear that the trade routes that ran from northwestern India to northern China facilitated both the introduction of Buddhism to Central Asia and the maintenance, for many centuries, of a flourishing Buddhist culture there.
By the beginning of the Common Era, Buddhism had probably been introduced into Eastern Turkistan. According to tradition, a son of Ashoka founded the kingdom of Khotan about 240 bce. The grandson of this king supposedly introduced Buddhism to Khotan, where it became the state religion. Other accounts indicate that the Indo-Scythian king Kaniska of the Kushan (Kusana) dynasty, which ruled in northern India, Afghanistan, and parts of Central Asia in the 1st to 2nd century ce, encouraged the spread of Buddhism into Central Asia. Kaniska purportedly called an important Buddhist council and patronized the Gandhara school of Buddhist art, which introduced Greek and Persian elements into Buddhist iconography. In the northern part of Chinese Turkistan, Buddhism spread from Kuqa (Kucha) to the kingdoms of Agnidesa (Karashahr), Gaochang (Torpan), and Bharuka (Aksu). According to Chinese travelers who visited Central Asia, the Hinayanists were strongest in Turpan, Shanshan, Kashi (Kashgar), and Kuqa, while Mahayana strongholds were located in Yarkant (Yarkand) and Hotan (Khotan).
