The Borders of Islam gives an insider’s view of the so-called “Islam’s bloody borders” through an examination of the countries that straddle two cultures/civilizations from across various regions. The book makes an enormous contribution to debates on “clash of civilizations” by critically examining various cases of war and conflict, which is one of the key elements of the thesis formulated by Samuel Huntington and popularized by the media. Hansen, Mesoy and Kardas take on Huntington’s main thesis with an aim to falsify it. The book stands out as one of the strongest counter-arguments to the main premises of the clash of civilizations thesis. It does so by arguing that the clash sometimes is constructed, as is the case of various internal and external conflicts taking place in and around Iraq, or it neglects the division within the Islamic civilization, as is the case with Lebanon where the Sunnis have a different agenda than the Shiite Muslims, or that the clash between Muslims and Christians is not necessarily religiously-driven in Nigeria, Ethiopia or Sudan. While laying out this argument, the book sets out to understand whether religion could be considered as the most tangible source of conflicts involving groups that hold different religious faiths.
