Since 1979, few rivalries have affected Middle Eastern politics as much as the rivalry between Saudi Arabia and Iran. However, too often the rivalry has been framed purely in terms of 'proxy wars', sectarian difference or the associated conflicts that have broken out in Iraq, Lebanon, Syria, Bahrain, and Yemen. In this book, Simon Mabon presents a more nuanced assessment of the rivalry, outlining its history and demonstrating its impact across the Middle East. Highlighting the significance of local groups, Mabon shows how regional politics have shaped and been shaped by the rivalry. The book draws from social theory and the work of Pierre Bourdieu to challenge problematic assumptions about 'proxy wars', the role of religion, and sectarianism. Exploring the changing political landscape of the Middle East as a whole and the implications for regional and international security, Mabon paints a complex picture of this frequently discussed but oft-misunderstood rivalry.
