"Like most colonial administrations, that of the Italians in Libya disregarded the culture of the Africans. However, after the fascist Mussolini came to power, the disregard gave way to active hostility, especially in relation to the Arabic language and the Moslem religion. The Portuguese and Spanish had always shown contempt for African language and religion. Schools of kindergarten and primary level for Africans in Portuguese colonies were nothing but agencies for the spread of the Portuguese language. Most schools were controlled by the Catholic church, as a reflection of the unity of church and state in fascist Portugal. In the little-known Spanish colony of Guinea (Rio Muni), the small amount of education given to Africans was based on eliminating the use of local languages by the pupils and on instilling in their hearts "the holy fear of God.""
