Abstract: With this paper we present an analysis of a group of white settlers almost completely neglected by historiography, the Catalans that migrated to Spanish Guinea (present-day Guinea Ecuatorial). We highlight how in spite of being rarely involved directly in the administration of the territory, Catalans were determinant to its economic evolution. Through a constant and systematic lobbying in both Guinea and Madrid, Catalan individuals, companies and institutions managed to influence the colonial policies of the Spanish government and to control the production and export of the main Guinean crop, cocoa. For a long period, Barcelona was the capital of a small empire in Equatorial Africa, and a national minority in the metropole became crucial in a colonial territory. Our study wishes to contribute to the knowledge of Guinean history and to the understanding of the diverse European communities settled in Africa.
