That's for they speak Spanish in most of the Central and South America, but Portuguese in Brazil. All the countries are mostly catholic, because of their catholic mothercountries. The Spanish conquistadors conquered the lands from Native Americans, of most notables were aztecs and incas. Mayan civilization collapsed before the Europeans came to America. The Native American religions were suppressed, although there are Native American population majorities in some South American countries, like Peru.
