What explains the breakout of violence following the repression of moderateIslamist groups in some Muslim countries? Part of the answer can lie in thepolitical organization style of those groups, which can constrain or expandtheir long-term strategy choices in unpredicted ways. Using examples fromAlgeria, Egypt, Indonesia, and Turkey, this study suggests that organizing as apolitical party can initially restrict the means of action otherwise availableto a moderate Islamist movement, while the loose framework of a political frontreduces its organizational costs and lends remarkable flexibility to attract awider range of followers. Later, paradoxically, the political party frameworkcan enable limited access of an Islamist group into the political systemotherwise completely inaccessible earlier, and help to enhance its power, whilepolitical fronts are exposed to attacks from both incumbent regimes and radicalIslamists groups alike.
