In spite of its integrative function, its ability to unite people and shape identities, and its contributions to peacebuilding and international development, sport has sometimes been a tool to divide groups and create identity tension. In the case of Jordan, soccer is not just a game; it goes far beyond that. It is a battleground. It is no longer a social phenomenon that contributes to the psychological health of the Jordanian society, it actually erodes the social and cultural fabric. This study provides the results of a 7-year longitudinal research of the role of sports in Jordan and how it fuels the national identity among ethnic Jordanians and Jordanian Palestinians. Drawing from 56 semi-structured interviews, archival work, media and social media, and personal experience, this article investigates the lifelong tension, and identity division has thus been existed between the two groups. The analysis stems from a detailed account of a rival history between two soccer teams and their fans. I argue that the blatant, sometimes overt, national identity-driven conflict between the two sides plays in the interests of the government, stabilizes the Hashemite regime, and shifts the attention of both parties from the Israeli-Palestinian Conflict. The analysis shows that, despite the fact that the two entities have been living together for decades, their national identities are on the borderline and source of conflict. This analysis is used to develop an analytical framework to further investigate the relationship between sports and identity conflict. This study advances the Value-Added Theory and the Social Identity Theory of intergroup behavior by stressing upon the relationship between collective behavior and forming social identity. The findings demonstrate that identity division is ingrained in the culture. This division is passed to generations through parents’ and grandparents’ narratives as “us vs. them”. Also, the two sides’ changing identity is a circumstantial phenomenon. In other words, their identities are shaped by a torn social fabric when the two teams play. Yet, this identity division fades away when the discussion comes to Israel. Interestingly enough, it seems that Jordanian Monarch is happy with this division given the two sides’ history.
