Wat Phra That Doi Suthep is a Theravada wat in Chiang Mai Province, Thailand. The temple is often referred to as “Doi Suthep” although this is actually the name of the mountain where it’s located. It is a sacred site to many Thai people. The temple is 15 kilometres (9.3 mi) from the city of Chiang Mai. From the temple, impressive views of Chiang Mai can be seen.

The original founding of the temple remains a legend and there are a few varied versions. The temple is said to have been founded in 1383 when the first stupa was built. Over time, the temple has expanded, and been made to look more extravagant with many more holy shrines added. A road to the temple was first built in 1935.

The wat can be reached by road from Chiang Mai. From the car park at the temple’s base visitors can climb 309 steps to reach the pagodas or take a tram.

Once inside the temple grounds visitors must be appropriately dressed and must remove footwear. The original copper plated chedi is the most holy area of the temple grounds. Within the site are pagodas, statues, bells, a museum, and shrines. Aspects of the wat draw from both Buddhism and Hinduism. There is a model of the Emerald Buddha and a statue of the Hindu God Ganesh. Views of Chiang Mai can be seen on the far side of the temple.

Buddhism in Thailand is largely of the Theravada school, which is followed by 93.6 percent of the population. Buddhism in Thailand has also become integrated with folk religion as well as Chinese religions from the large Thai Chinese population.

During the 5th to 13th centuries, Southeast Asian empires were influenced directly from India and followed Mahayana Buddhism. The Chinese pilgrim Yijing noted in his travels that in these areas, all major sects of Indian Buddhism flourished. Srivijaya to the south and the Khmer Empire to the north competed for influence and their art expressed the rich Mahāyāna pantheon of bodhisattvas. From the 9th to the 13th centuries, the Mahāyāna and Hindu Khmer Empire dominated much of the Southeast Asian peninsula. Under the Khmer Empire, more than 900 temples were built in Cambodia and in neighboring Thailand.

After the decline of Buddhism in India, missions of Sinhalese monks gradually converted the Mon people and the Pyu city-states from Ari Buddhism to Theravāda and over the next two centuries also brought Theravāda Buddhism to the Bamar people, Thailand, Laos and Cambodia, where it supplanted previous forms of Buddhism. Theravada Buddhism was made the state religion only with the establishment of the Sukhothai Kingdom in the 13th century

Buddhist temples in Thailand are characterized by tall golden stupas, and the Buddhist architecture of Thailand is similar to that in other Southeast Asian countries, particularly Cambodia and Laos, with which Thailand shares cultural and historical heritage.

The details of the history of Buddhism in Thailand from the 13th to the 19th century are obscure, in part because few historical records or religious texts survived the Burmese destruction of Ayutthaya, the capital city of the kingdom, in 1767. The anthropologist-historian S. J. Tambiah, however, has suggested a general pattern for that era, at least with respect to the relations between Buddhism and the sangha on the one hand and the king on the other hand. In Thailand, as in other Theravada Buddhist kingdoms, the king was in principle thought of as patron and protector of the religion (sasana) and the sangha, while sasana and the sangha were considered in turn the treasures of the polity and the signs of its legitimacy. Religion and polity, however, remained separate domains, and in ordinary times the organizational links between the sangha and the king were not close.

Among the chief characteristics of Thai kingdoms and principalities in the centuries before 1800 were the tendency to expand and contract, problems of succession, and the changing scope of the king’s authority. In effect, some Thai kings had greater power over larger territories, others less, and almost invariably a king who sought successfully to expand his power also exercised greater control over the sangha. That control was coupled with greater support and patronage of the ecclesiastical hierarchy. When a king was weak, however, protection and supervision of the sangha also weakened, and the sangha declined. This fluctuating pattern appears to have continued until the emergence of the Chakri Dynasty in the last quarter of the 18th century.

By the 19th century, and especially with the coming to power in 1851 of King Mongkut, who had been a monk himself for twenty-seven years, the sangha, like the kingdom, became steadily more centralized and hierarchical in nature and its links to the state more institutionalized. As a monk, Mongkut was a distinguished scholar of Pali Buddhist scripture. Moreover, at that time the immigration of numbers of monks from Burma was introducing the more rigorous discipline characteristic of the Mon sangha. Influenced by the Mon and guided by his own understanding of the Tipitaka, Mongkut began a reform movement that later became the basis for the Dhammayuttika order of monks.

Under the reform, all practices having no authority other than custom were to be abandoned, canonical regulations were to be followed not mechanically but in spirit, and acts intended to improve an individual’s standing on the road to nirvana but having no social value were rejected. This more rigorous discipline was adopted in its entirety by only a small minority of monasteries and monks. The Mahanikaya order, perhaps somewhat influenced by Mongkut’s reforms but with a less exacting discipline than the Dhammayuttika order, comprised about 95 percent of all monks in 1970 and probably about the same percentage in the late 1980s. In any case, Mongkut was in a position to regularize and tighten the relations between monarchy and sangha at a time when the monarchy was expanding its control over the country in general and developing the kind of bureaucracy necessary to such control. The administrative and sangha reforms that Mongkut started were continued by his successor. In 1902 King Chulalongkorn (Rama V, 1868–1910) made the new sangha hierarchy formal and permanent through the Sangha Law of 1902, which remained the foundation of sangha administration in modern Thailand.

The history of Buddhism spans from the 5th century BCE to the present; which arose in the eastern part of Ancient India, in and around the ancient Kingdom of Magadha (now in Bihar, India), and is based on the teachings of Siddhārtha Gautama. This makes it one of the oldest religions practiced today. The religion evolved as it spread from the northeastern region of the Indian subcontinent through Central, East, and Southeast Asia. At one time or another, it influenced most of the Asian continent. The history of Buddhism is also characterized by the development of numerous movements, schisms, and schools, among them the Theravāda, Mahāyāna and Vajrayāna traditions, with contrasting periods of expansion and retreat.

Siddhārtha Gautama was the historical founder of Buddhism. He was born a Kshatriya warrior prince in Lumbini, Shakya Republic, which was part of the Kosala realm of ancient India, now in modern-day Nepal. He is also known as the Shakyamuni (literally: “The sage of the Shakya clan”). After an early life of luxury under the protection of his father, Śuddhodhana, the ruler of Kapilavasthu which later became incorporated into the state of Magadha, Siddhartha entered into contact with the realities of the world and concluded that life was inescapably bound up with suffering and sorrow. Siddhartha renounced his meaningless life of luxury to become an ascetic. He ultimately decided that asceticism couldn’t end suffering, and instead chose a middle way, a path of moderation away from the extremes of self-indulgence and self-mortification.

Under a fig tree, now known as the Bodhi tree, he vowed never to leave the position until he found Truth. At the age of 35, he attained Enlightenment. He was then known as Gautama Buddha, or simply “The Buddha”, which means “the enlightened one”, or “the awakened one”.  For the remaining 45 years of his life, he traveled the Gangetic Plain of central India (the region of the Ganges/Ganga river and its tributaries), teaching his doctrine and discipline to a diverse range of people. By the time of his death, he had thousands of followers.

The Buddha’s reluctance to name a successor or to formalise his doctrine led to the emergence of many movements during the next 400 years: first the schools of Nikaya Buddhism, of which only Theravada remains today, and then the formation of Mahayana and Vajrayana, pan-Buddhist sects based on the acceptance of new scriptures and the revision of older techniques. Followers of Buddhism, called Buddhists in English, referred to themselves as Sakyan-s or Sakyabhiksu in ancient India. Buddhist scholar Donald S. Lopez asserts they also used the term Bauddha, although scholar Richard Cohen asserts that that term was used only by outsiders to describe Buddhists.

During the 1st century AD, the trade on the overland Silk Road tended to be restricted by the rise in the Middle-East of the Parthian empire, an unvanquished enemy of Rome, just as Romans were becoming extremely wealthy and their demand for Asian luxury was rising. This demand revived the sea connections between the Mediterranean and China, with India as the intermediary of choice. From that time, through trade connection, commercial settlements, and even political interventions, India started to strongly influence Southeast Asian countries (excluding Vietnam). Trade routes linked India with southern Burma, central and southern Siam, islands of Sumatra and Java, lower Cambodia and Champa, and numerous urbanized coastal settlements were established there.

For more than a thousand years, Indian influence was therefore the major factor that brought a certain level of cultural unity to the various countries of the region. The Pāli and Sanskrit languages and the Indian script, together with Theravāda and Mahāyāna Buddhism, Brahmanism, and Hinduism, were transmitted from direct contact and through sacred texts and Indian literature such as the Rāmāyaṇa and the Mahābhārata.

From the 5th to the 13th centuries, South-East Asia had very powerful empires and became extremely active in Buddhist architectural and artistic creation. The main Buddhist influence now came directly by sea from the Indian subcontinent, so that these empires essentially followed the Mahāyāna faith. The Sri Vijaya Empire to the south and the Khmer Empire to the north competed for influence, and their art expressed the rich Mahāyāna pantheon of the bodhisattvas.

From the 11th century, the destruction of Buddhism in the Indian mainland by Islamic invasions led to the decline of the Mahāyāna faith in South-East Asia. Continental routes through the Indian subcontinent being compromised, direct sea routes developed from the Middle-East through Sri Lanka to China, leading to the adoption of the Theravāda Buddhism of the Pāli canon, introduced to the region around the 11th century from Sri Lanka.King Anawrahta (1044–1078); the founder of the Pagan Empire, unified the country and adopted the Theravādin Buddhist faith. This initiated the creation of thousands of Buddhist temples at Pagan, the capital, between the 11th and 13th centuries. Around 2,200 of them are still standing. The power of the Burmese waned with the rise of the Thai, and with the seizure of the capital Pagan by the Mongols in 1287, but Theravāda Buddhism remained the main Burmese faith to this day.

The Theravāda faith was also adopted by the newly founded ethnic Thai kingdom of Sukhothai around 1260. Theravāda Buddhism was further reinforced during the Ayutthaya period (14th–18th century), becoming an integral part of Thai society.

In the continental areas, Theravāda Buddhism continued to expand into Laos and Cambodia in the 13th century. From the 14th century, however, on the coastal fringes and in the islands of south-east Asia, the influence of Islam proved stronger, expanding into Malaysia, Indonesia, and most of the islands as far as the southern Philippines.

Nevertheless, since Suharto’s rise to power in 1966, there has been a remarkable renaissance of Buddhism in Indonesia. This is partly due to the requirements of Suharto’s New Order for the people of Indonesia to adopt one of the five official religions: Islam, Protestantism, Catholicism, Hinduism or Buddhism. Today it is estimated there are some 10 million Buddhists in Indonesia. A large part of them are people of Chinese ancestry.
