This article focuses on the transnational project, led by Turkish Independent Industrialists and Businessmen Association (Müsiad), of crafting a community of Islamic businessmen. The Arab Springs opened new opportunities to further this project, especially in Tunisia and Egypt where Islamist groups rose to power after 2011. In both countries, Müsiad supported the creation of two Islamic business associations, exporting its own organizational model. Examining this circulation process, we question the classical dichotomy between economic and advocacy transnational networks. We also show how this transnational activism is constrained by divergent domestic patterns of relationships between Islamists, business and states in each country. \textcopyright 2017, \textcopyright 2017 Informa UK Limited, trading as Taylor & Francis Group.
