Religion in Cambodia (2010)
Approximately 95% of Cambodia's population follows Theravada Buddhism, with Islam, Christianity, and tribal animism making up the bulk of the remainder. The wat (Buddhist monastery) and Sangha (monkhood), together with essential Buddhist doctrines such as reincarnation and the accumulation of merit, are at the centre of religious life, but interact with indigenous beliefs such as the central role of ancestors and spirits.
Buddhism has existed in Cambodia since at least the 5th century AD, with some sources placing its origin as early as the 3rd century BC. Theravada Buddhism has been the Cambodian state religion since the 13th century AD (excepting the Khmer Rouge period), and is currently estimated to be the religion of 95% of the population.
The history of Buddhism in Cambodia spans nearly two thousand years, across a number of successive kingdoms and empires. Buddhism entered Cambodia through two different streams. The earliest forms of Buddhism, along with Hindu influences, entered the Funan kingdom with Hindu merchants. In later history, a second stream of Buddhism entered Khmer culture during the Angkor empire when Cambodia absorbed the various Buddhist traditions of the Mon kingdoms of Dvaravati and Haripunchai.
For the first thousand years of Khmer history, Cambodia was ruled by a series of Hindu kings with an occasional Buddhist king, such as Jayavarman I of Funan, and Suryvarman I. A variety of Buddhist traditions co-existed peacefully throughout Cambodian lands, under the tolerant auspices of Hindu kings and the neighboring Mon-Theravada kingdoms.
Cambodia was first influenced by Hinduism during the beginning of the Kingdom of Funan. Hinduism was one of the Khmer Empire's official religions. Cambodia is the home to one of the only two temples dedicated to Brahma in the world. Angkor Wat of Cambodia is the largest Hindu temple of the world.
Islam is the religion of a majority of the Cham and Malay minorities in Cambodia. According to Po Dharma, there were 150,000 to 200,000 Muslims in Cambodia as late as 1975 while Ben Kiernan's research documents numbers as high as 250,000. Persecution under the Khmer Rouge eroded their numbers, however, and by the late 1980s they probably had not regained their former strength. All of the Cham Muslims are Sunnis of the Shafi'i school. Po Dharma divides the Muslim Cham in Cambodia into a traditionalist branch and an orthodox branch.
