Tourism is often heralded as a force for peace, however, empirical research to confirm this suggestion is scant. To address this gap, this research integrates several datasets on conflict and tourism to examine whether a larger inflow of tourists makes civil conflict less likely. Several theoretical arguments of the role of tourism alongside other peace determining factors are presented. These inform the development of a probit model, and several specifications, that tests the hypothesis based on data from 126 countries and for the years from 1995 to 2010. The findings provide strong evidence that increasing tourism arrivals have a stabilising effect and increase the chance of peace. Implications for tourism and its role in the process of development are discussed.
