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: The 20th-century Nepalese Theravāda movement which introduced Theravāda Buddhism to Nepal and was led by prominent figures such as Dharmaditya Dharmacharya, Mahapragya, Pragyananda and Dhammalok Mahasthavir. The establishment of some of the first Theravāda Viharas in the Western world, such as the London Buddhist Vihara (1926), Das Buddhistische Haus in Berlin (1957) and the Washington Buddhist Vihara in Washington, DC (1965).
