Invisible Revolutionaries sheds light on the critical role women play in contemporary revolutions around the world. The book argues that women's engagement in contentious politics is often far less visible than men's participation, when measured by the physical presence of women in protest space. Using the case of the 2013–2014 Euromaidan in Ukraine, the book outlines the different models and dimensions for women's participation in revolutions and illustrates how women in Ukraine have been at the forefront of pro-democracy movements, fiercely resisting Russia's invasion and fighting for national independence and democratic development. Drawing on data from large-N surveys and oral history projects, the book uncovers the diverse motivations and forms of women's participation and traces the multifaceted outcomes of women's activism. The book makes a significant contribution, addressing a key moment in Ukraine's history that is of renewed importance after the full-scale Russian invasion in 2022.
