In context

Hòa Hảo Buddhism emerged in 1939 Vietnam under Huỳnh Phú Sổ (the 'Mad Monk') as a reformist lay-Buddhist movement emphasising simplicity over institutional Buddhism. Sổ disappeared in 1947, presumed killed by the Viet Minh. The movement was historically a political-religious force in southern Vietnam. Day-to-day religious life is light; political and social tensions with the Vietnamese state continue.
