The three articles that make up this thesis consider the diverse forms of contentious politics and mass mobilization that emerged during the 25th January Egyptian Revolution in 2011 and its aftermath. The first article, discussing the eighteen days of anti-Mubarak protest, pays special attention to the position of the Egyptian army in and around Midan al-Tahrir, and recounts how protestors sought to co-opt and neutralize the threat posed by regime forces. It finds that fraternizing protestors developed a repertoire of contention that made situational, emotional claims on the loyalty of regime troops. The second article explores the role of elections and protests during the failed democratic transition away from authoritarian rule that began on 11 February with Mubarak’s resignation and ended on 3 July 2013 with a military coup. Highlighting the Muslim Brothers’ demobilization and privileging of procedural democracy following Mubarak’s ousting, it offers an alternative account of where and when Egypt’s democratic project went wrong. The final article considers opposition to the 3 July coup and in particular the effects of state repression on the daily street protests launched by the Muslim Brothers and their allies in the post-coup period. Far from being defeated, anti-coup contention, it is suggested, has instead been contained in ways that have made protest less visible and less disruptive over time. Taken as a whole, the thesis suggests new ways to understand and explain the 25th January Revolution, its trajectories and legacies.
