The Muslim Brotherhood is one of the oldest and most influential Islamist movements. As the party ascends to power in Egypt, it is poised to adopt a new system of governance and state-society relations, the effects of which are likely to extend well beyond Egypt's national borders. This book examines the Brotherhood's visions and practices, from its inception in 1928, up to its response to the 2011 uprising, as it moves to redefine democracy along Islamic lines. The book analyses the Muslim Brotherhood's position on key issues such as gender, religious minorities, and political plurality, and critically analyses whether claims that the Brotherhood has abandoned extremism and should be engaged with as a moderate political force can be substantiated. It also considers the wider political context of the region, and assesses the extent to which the Brotherhood has the potential to transform politics in the Middle East.
