In this book, editors Mecham and Hwang, and their contributors, examine the impact that political parties with Islamic agendas have on political processes in the Middle East and Asia. They explain that Islamist parties typically use Islamic religious narratives to make political claims on the state, based on Islamic social and cultural norms, models of governance, and resource allocation towards religious institutions. They analyze the evolution of Islamist parties, and the participation of Islamists parties in democratic and semi-democratic systems, specifically in Turkey, Morocco, Yemen, Indonesia, Malaysia, and Bangladesh. Each chapter analyzes different case studies of Islamist political parties within the states presented above. They examine the similarities Islamist parties have to other political parties, arguing that surprisingly, they are not too different due to the electoral politics that all parties must engage in. Mecham and Hwang argue that contrary to belief, Islamist parties are not as uniform as they may seem. They argue that these groups represent a diverse set of interests and political behaviors that are specific to their given domestic context.
