When the Arab Spring of 2011 sparked a second revolution in Egypt (the first having occurred in 1952), it caught the longstanding Muslim Brotherhood almost by surprise. Arguably the oldest Sunni political mass movement in Egypt (having been established in 1928), it had proven remarkably resilient during more than eight decades of alternating repression and toleration by subsequent governments. Though its social composition changed over the years, its principles, as laid down by its founder Hasan al-Banna, continued to inspire large segments of the population in a quest for a state based on Shariʿa, and provided an alternative vision for a more just and moral society. Meanwhile, the Brotherhood built a wide network of social, educational, and welfare institutions. From the early 1980s onwards, with Mubarak in power, the Brotherhood was condoned, if not officially recognized, and members were allowed to participate in several parliamentary and other elections. As an organization with formal traditional leadership bodies, but also a younger generation versed in the modern social media, the Brotherhood was seen to be slowly nearing a point where it would be able to make the transition to a party. It began to formulate a political platform and an economic blueprint for the country. A modicum of democracy was adopted, and more openness towards the integration of women was seen. After winning a relatively large (minority) representation in the 2005 parliamentary elections, the regime was scared enough to allow the Brotherhood to win only one token seat in 2010. The revolution of 2011 ousted Mubarak and then led to relatively free elections with a solid victory for the Freedom and Justice Party, which had been formed by the Brotherhood, as well as a new Islamist-inspired constitution and the election of Muhammad Mursi as president. However, within a year the Muslim Brotherhood government had missed this historical window of opportunity. It proved inadequately prepared for efficient and orderly governance, did not bring order and stability, nor did it advance the aspirational goals of demonstrators. This is how the army, not for the first time in Egypt’s history, came to intervene and depose Morsi in July 2013, replacing him with Defense Minister ʿAbd al-Fattah al-Sisi. It was not long before the Brotherhood was once more suppressed and outlawed. With many leaders in jail, but latent support continuing, observers tend to believe it is not the end of the Brotherhood’s existence.
