Despite the evident involvement of women in terrorism, the subject continues to be clouded by androcentric perspectives. This leads to a limited understanding of the important roles women possess within radical Islamist and non-Islamist groups, such as al-Qaeda and IS, and the Chechen Black Widows and the Liberation Tigers of Tamil Eelam (LTTE). Not fully understanding the dimensions of women’s participation in terrorist groups impedes effective policymaking to curb their radicalisation processes. Hence, this edited book will bring together diverse perspectives and case studies from different countries/regions on women in extremist and terrorist groups to draw some key lessons challenging mainstream assumptions and present policies on the subject.
