The Arab Spring protests in 2011 uprooted regimes, challenged authoritarian leaders, and provided protesters new tools for mobilization. The use of social media and the involvement of women in public protests indicated changing protest repertoires and movement demographics in many countries. When women protested in 2011, they mobilized both physically and virtually. Assessing the influence women exert in social movements through social media can provide insights into factors that make a social movement successful. This thesis ascertains that women physically mobilized to participate in the Arab Spring protests in Egypt, Yemen, and Bahrain. In Egypt and Bahrain, women also mobilized virtually using social media, while in Yemen women participated through traditional forms of social mobilization.
