This article draws attention to a young generation of Islamist women activists and to how it reacted to the patriarchal tendencies of the Muslim Brotherhood (MB) movement following the January 25, 2011 revolution in Egypt. Although women’s support was central to the ability of Islamists to win power, after the uprising Islamists failed to grant women significant political rights and autonomy. While the existing literature on gender and nationalism demonstrates that practical gains for women are frequently sidelined by their movements in a post-revolutionary era, there is increasing recognition to examine the relationship between feminism and nationalism in relation to the particular context in which this evolves. This article substantiates this claim with new evidence. Based on a feminist ethnographic study of the Muslim Sisterhood, the female members of the Egyptian MB movement, conducted in Cairo between 2013 and 2018, the article demonstrates that a new gender politics has emerged among Islamist women activists as a result of their engagement in revolutionary struggle. This gender politics has explicit feminist overtones, which have become evident as women begin to challenge men’s position of privilege within the sphere of the family.
