The fourteenth Arab historian Ibn Khaldun, in his Muqaddimah (Introduction to History), explained political change and the rise and fall of dynasties as a function of the interactions among positive and/or negative factors for the political changes such as asabiyah (social cohesion or group feeling), religion, military might, financial capability(tax revenues), political leadership, corruption, and injustice. This study analyzes the Ibn Khaldun`s political change theory, and examines the factors, which contribute to the political changes. This study also reviews the cases of the application of Ibn Khaldun`s political change theory to political changes in the modern Middle East by contemporary scholars. And then we examine the developmental processes of Hamas, a Palestinian radical Islamic movement, and its evolution into a political party which succeeded in entering into Palestinian mainstream institutional politics with the Ibn Khaldun`s political change theory. In the concluding chapter, it examines the implication of Ibn Khaldun`s political change theory in studies of contemporary political change in the Middle East and finds its applicability in that studies.
