Based on a wealth of new primary data, this book offers the first account of the internal regime factors that ultimately caused the fall of Zine el-Abidine Ben Ali's long dictatorship in Tunisia during the Arab Uprisings. Anne Wolf's account challenges studies that focus on the role of mass mobilization alone, and demonstrates that in the last decade of Ben Ali's presidency, dissent within his ruling party - the Constitutional Democratic Rally - mounted to such an extent that followers began challenging their own powerbroker. The culmination of this was a secret coup d'état staged by regime figures against Ben Ali in January 2011, an event that has not previously been uncovered. Wolf proposes a new theory of power and contention within ruling parties in authoritarian regimes to explain how dictators seek to fortify their rule and foster party-political stability, but also when, why, and how they succumb to internal contention and with what effect.
