The aim of this article was to analyse the initiative FC Barcelona Peace Tour 2013, in Israel and Palestine. This research is based on lengthy interviews with people associated with the initiative and the use of primary sources, both institutional and journalistic. Secondary sources have also been used, such as journalistic accounts of the initiative. The article thus examines the nature of FC Barcelona Peace Tour 2013, which it defines as an exercise in sports diplomacy, inspired by civil society and articulated through the club. The article concludes that FC Barcelona has been able to act as a mediator between two opposed communities due to the universal values linked to its brand and its nature as a ‘civil religion’. This notwithstanding, the political problems that arose during the planning of the initiative highlight the geopolitical complexity of the Middle East and, by extension, the limits of sports diplomacy.
