The global geography of art has changed greatly in recent years. Whereas global art hubs were formerly found only in the West, they now exist in locations all over the world, including Africa. Though some art worlds in Asia and Latin America have been studied in recent times, there is insufficient empirical data on art worlds in Africa. This is a study of the Lagos art world, which shows how an “art system,” with all of its attendant structures and agents, has emerged in the city of Lagos, Nigeria, in the last few years. Lagos reflects the dynamics of globalization and is building up the art infrastructure and the critical mass needed for a sustainable art world: an ambitious and fast-growing group of young local collectors, an art fair, an international photography festival, regular art auctions, new art galleries, historical and critical publications, a university art museum, symposiums, art foundations, residencies, and competitions. Lagos is becoming not only a “global city,” but also a “global art hub.”
