Modern history

In the 19th and 20th centuries, Theravāda Buddhists came into direct contact with western ideologies, religions and modern science. The various responses to this encounter have been called " Buddhist modernism ". In the British colonies of Ceylon (modern Sri Lanka) and Burma (Myanmar), Buddhist institutions lost their traditional role as the prime providers of education (a role that was often filled by Christian schools). In response to this, Buddhist organizations were founded which sought to preserve Buddhist scholarship and provide a Buddhist education. Anagarika Dhammapala, Migettuwatte Gunananda Thera, Hikkaduwe Sri Sumangala Thera and Henry Steel Olcott (one of the first American western converts to Buddhism) were some of the main figures of the Sri Lankan Buddhist revival. Two new monastic orders were formed in the 19th century, the Amarapura Nikāya and the Rāmañña Nikāya.

In Burma, an influential modernist figure was king Mindon Min (1808–1878), known for his patronage of the Fifth Buddhist council (1871) and the Tripiṭaka tablets at Kuthodaw Pagoda (still the world's largest book) with the intention of preserving the Buddha Dhamma. Burma also saw the growth of the " Vipassana movement ", which focused on reviving Buddhist meditation and doctrinal learning. Ledi Sayadaw (1846–1923) was one of the key figures in this movement. After independence, Myanmar held the Sixth Buddhist council (Vesak 1954 to Vesak 1956) to create a new redaction of the Pāli Canon, which was then published by the government in 40 volumes. The Vipassana movement continued to grow after independence, becoming an international movement with centers around the world. Influential meditation teachers of the post-independence era include U Narada, Mahasi Sayadaw, Sayadaw U Pandita, Nyanaponika Thera, Webu Sayadaw, U Ba Khin and his student S.N. Goenka.

Meanwhile, in Thailand (the only Theravāda nation to retain its independence throughout the colonial era), the religion became much more centralized, bureaucratized and controlled by the state after a series of reforms promoted by Thai kings of the Chakri dynasty. King Mongkut (r. 1851–1868) and his successor Chulalongkorn (1868–1910) were especially involved in centralizing sangha reforms. Under these kings, the sangha was organized into a hierarchical bureaucracy led by the Sangha Council of Elders (Pali: Mahāthera Samāgama), the highest body of the Thai sangha. Mongkut also led the creation of a new monastic order, the Dhammayuttika Nikaya, which kept a stricter monastic discipline than the rest of the Thai sangha (this included not using money, not storing up food and not taking milk in the evening). The Dhammayuttika movement was characterized by an emphasis on the original Pali Canon and a rejection of Thai folk beliefs which were seen as irrational. Under the leadership of Prince Wachirayan Warorot, a new education and examination system was introduced for Thai monks.

The 20th century also saw the growth of "forest traditions" which focused on forest living and strict monastic discipline. The main forest movements of this era are the Sri Lankan Forest Tradition and the Thai Forest Tradition, founded by Ajahn Mun (1870–1949) and his students.

Theravāda Buddhism in Cambodia and Laos went through similar experiences in the modern era. Both had to endure French colonialism, destructive civil wars and oppressive communist governments. Under French Rule, French indologists of the École française d'Extrême-Orient became involved in the reform of Buddhism, setting up institutions for the training of Cambodian and Lao monks, such as the Ecole de Pali which was founded in Phnom Penh in 1914. While the Khmer Rouge effectively destroyed Cambodia's Buddhist institutions, after the end of the communist regime the Cambodian Sangha was re-established by monks who had returned from exile. In contrast, communist rule in Laos was less destructive since the Pathet Lao sought to make use of the sangha for political ends by imposing direct state control. During the late 1980s and 1990s, the official attitudes toward Buddhism began to liberalise in Laos and there was a resurgence of traditional Buddhist activities such as merit-making and doctrinal study.

The modern era also saw the spread of Theravāda Buddhism around the world and the revival of the religion in places where it remains a minority faith. Some of the major events of the spread of modern Theravāda include:
