About 85% of all Guineans, particularly the Fulani and Malinké, are Muslims; about 10% follow various Christian faiths; and most of the remaining 5% practice traditional African religions. Most Muslims belong to the Sunni sect, and practices, particularly public prayers and the prescribed fasts, are often combined with animist beliefs and ceremonies. Christian missions were established in the 19th century, but converts have been few. Among Christian groups are Roman Catholics, Anglicans, Baptists, Jehovah's Witnesses, Seventh-Day Adventists, and various other evangelical churches. There are a small number of Baha'is, Hindus, Buddhists, and observers of traditional Chinese religions.
In May 1967, President Sékou Touré ordered that only Guinean nationals be allowed to serve in the country's Roman Catholic priesthood. The Catholic archbishop in Conakry was sentenced to life imprisonment at hard labor in 1971 for allegedly plotting against the state; he was released in August 1979. In 1984 private education, long prohibited by the government, was again permitted.
Certain holidays of both Islam and Christianity are recognized as public holidays.
