Although African traditional religion has left its vestiges among the indigenous tribes, about 93% of the population are Christian. Within the Christian population, 87% are Roman Catholic and about 5% are mainline Protestant, primarily Baptist and Episcopalian. Though there is no state religion, a 1992 law established an official preference for the Catholic Church and the Reform Church of Equatorial Guinea, based on the traditional importance of these two denominations in popular culture. Religious study (primarily Catholic) is required in public schools.
