The main purpose of "The relations between the Portuguese government and the Muslims of Mozambique (1930-1970) is to examine the different positions taken by the Portuguese colonial government towards the Muslims of Mozambique. Since the arrival of the Portuguese in the region in the sixteenth century, until their expulsion in 1974, the contact between Portuguese and Muslims was permeated by the antinomy alliance - opposition. Between the 30s and 60s, Islamism in Mozambique was seen as a threat to the project of the Portuguese nation and was suppressed in many different ways. However, between the 60s and 70s, when the emancipation movements of the Portuguese colonies were strengthened and the armed struggle began, the New State took a different stance regarding its Muslim population. A strategic approach was created, based on a discourse of ecumenical dialogue and the knowledge acquired about the various Islamic communities in the territory, concentrated mainly in the north part of the country.
