This chapter analyzes Egypt’s 2011 revolution and 2013 coup, one of the most prominent counterrevolutions of the 21st century. Drawing on approximately 100 original interviews with Egyptian politicians and activists, it argues that Egypt’s counterrevolution only became possible when revolutionaries squandered their initial capacity to hold the old regime’s military in check and presented them with an opportunity to rebuild their popular support. Specifically, the chapter makes the following claims: (1) revolutionary forces began the transition with considerable leverage over the former regime, grounded in their ability to threaten a return to mass mobilization and their backing from the United States; (2) after Mohamed Morsi was elected president, his administration’s poor management of the post-revolutionary governance trilemma, particularly its decision to prioritize the concerns of old regime elements over those of his secularist allies, caused the revolutionary coalition to fracture and Washington to begin questioning its support; and (3) these developments created opportunities for the military to bolster its domestic and foreign support and sapped revolutionaries’ capacity to resist a counterrevolutionary coup. Ultimately, the chapter concludes that, though the task facing Egypt’s revolutionary leaders was not easy, a counterrevolutionary end to the transition was far from a foregone conclusion.
