This book sets out to explain the foreign policy of Italian Prime Minister Matteo Renzi (February 2014 to December 2016). It offers a unique analytical framework to make sense of Renzi's foreign policy: the domestically-focused outsider. It argues that to untangle Renzi's foreign policy one must first understand that his clear priority was enacting domestic economic and political reforms. Domestic focus means that Renzi made foreign policy decisions with a sensitivity to public opinion and party unity. The book also argues that Renzi's status as an outsider in Italian politics-having previously served only as the mayor of Florence-provides critical insight into his foreign policy. Renzi was prone to skepticism of the establishment and dramatic, symbolic gestures rather than patient coalition building. The book applies this framework to the five most important foreign policy issues Renzi's government faced: migration, finance and the EU, Russia, ISIL, and Libya. The book's analysis of the cases benefits from over twenty elite interviews, including those with senior members of Renzi's government.
