The uprisings that swept the Arab world following the fall of Tunisia’s President Zine el-Abidine Ben Ali in January 2011 represented a stunning moment in the region’s political history. For political scientists specializing in the region, the events of the last year and a half represented an exhilarating moment of potential change but also an important opportunity to develop new research questions, engage in new comparisons, and exploit new data and information. The Arab uprisings challenged long-held theories dominant in the field, particularly about the resilience of authoritarian regimes, while opening up entirely new areas of legitimate social scientific inquiry.
