DescriptionWhat explains the increase in moderate Islamists movements in the Middle East? Why do Islamist movements at times adopt moderate strategies while others do not? What conditions facilitate Islamist ideological moderation? And finally, what effect does the integration of Islamists into the political arena have on the state? The central claim of this study is that the moderation of opposition movements is the outcome of political processes that involve the tension among three variables: political inclusion, internal organization of the movement, and ideological frames. Over time, the interaction of these affects the trajectory of an Islamist movement, such as the Muslim Brotherhood, ultimately leading to sustained ideological change.
