Like Laos and Thailand, Buddhist has been the dominant religion in Cambodia for centuries. About 95% of the Cambodia population is Theravada Buddhist follower, 5% of the population follows Hinduism, Islam and Christianity.
Buddhist was introduced in Cambodia since at least 5th century AD in two different streams: one along with Hindu influences in the early history of Funan Kingdom through Hindu merchants, one during the Angkor Empire when Cambodia absorbed the various Buddhist traditions of the Mon Kingdoms.More info
Christianity appeared in Cambodia in the center of 16th century undertaken by Gaspa da Cruz - a Portugese man. Despite the French colonization in the 19th century, Christianity made little impact in the country. There are around 20,000 Catholics in Cambodia which represents 0.15% of the total population.More info
