Buddhism is the fourth largest religion in France, after Christianity, Islam, and Judaism.
France has over two hundred Buddhist meditation centers, including about twenty sizable retreat centers in rural areas. The Buddhist population mainly consists of Chinese, Vietnamese, and Korean immigrants, with a substantial minority of native French converts and "sympathizers." The rising popularity of Buddhism in France has been the subject of considerable discussion in the French media and academy in recent years.
In the early 1990s, the French Buddhist Union (UBF, founded in 1986) estimated there to be 600,000 to 650,000 Buddhists in France, with 150,000 French converts among them. In 1999, sociologist Frédéric Lenoir estimated there are 10,000 converts and up to 5 million "sympathizers," although other researchers have questioned these numbers. A 1997 opinion poll counted as sympathizers young people who feel "an intellectual affinity with Buddhism or expressed a sympathy to a Buddhist worldview."
Alexandra David-Néel was an important early French Buddhist. She is best known for her 1924 visit to the forbidden (to foreigners) city of Lhasa, capital of Tibet, and wrote more than 30 books about Buddhism, philosophy, and her travels. In 1911 Alexandra traveled to India, to further her study of Buddhism. She was invited to the royal monastery of Sikkim, where she met Maharaj Kumar (crown prince) Sidkeon Tulku. She became Sidkeong's "confidante and spiritual sister" (according to Ruth Middleton), and perhaps his lover (Foster & Foster). She also met the thirteenth Dalai Lama twice in 1912, and had the opportunity to ask him many questions about Buddhism—a feat unprecedented for a European woman at that time.
In the late 1960s and early 1970s, Buddhist teachers of various traditions began to visit France, as detailed below.
Taisen Deshimaru was a Japanese Zen Buddhist who founded numerous zendos in France. Thich Nhat Hanh Vietnamese-born Zen Buddhist nominated for the Nobel Peace Prize by Martin Luther King, founded the Unified Buddhist Church (Eglise Bouddhique Unifiée) in France in 1969. Plum Village, a monastery and retreat center in the Dordogne in southern France, is his residence and the headquarters of his international sangha.
