This book analyses the reasons for women's participation in the various Lebanese and Palestinian militias involved in the Lebanese Civil War (1975-1990). Whilst most existing accounts of the Civil War in Lebanon either overlook the roles and experiences of women entirely or focus on women as victims or peacemakers only, this work highlights that women were involved as militants (and often also as fighters) in all of the militias partaking in the war. Analyzing individual motivations, organizational characteristics, security-related aspects and societal factors, the book explains why women were included as fighters in some of the militias but not in others. Based on extensive fieldwork in Lebanon, the book is the first comprehensive study of female perpetrators and supporters of political violence during the Lebanese Civil War. Beyond the case of Lebanon, it questions widespread assumptions about the roles of women at times of violent conflict and war.
