In 2017 AIVD approximated the number of female jihadists in the Netherlands to be about 100 and at least 80 women had left the Netherlands to join the conflict, the majority of whom joined ISIS.[38] Jihadist women in the Netherlands encourage both men and women to believe in their ideology by entering into discussions online and offline as well as spreading jihadist propaganda. Jihadist women also help travellers to conflict zones by providing material support or putting them in touch with facilitators.
