The identity of women, which has become radicalized and involved in violence and terrorism, is a historical phenomenon. This reality is very valid for modern period terrorist organizations. Women's identity is the founder and leader of many ideological terrorist organizations. However, the situation is different in terrorist organizations based on religious motives and exploitation. In such organizations, female militants are not only overshadowed by male militants, they are also anonymous and appear to the extent permitted by the leader. The same is true for the Fetullah Terrorist Organization (FETO) elder sisters. In fact, the name and identity of the woman did not exist during the founding years of FETO. However, this situation changed later and it was instrumentalized for organizational purposes as if the identity of women was suddenly discovered. For this, the organization has established the elder sisterhood system and the catalog marriage system. With these two systems, both the identity of women and the institution of marriage have been exploited for organizational benefits. FETÖ has actively used female militants for years and employed them in many jobs, but has not appointed any of them as senior managers or administrators. Despite this, the radicalized militant women of FETO undertook many tasks for organizational interests. For this reason, it is very important that the women militants of the organization are not ignored in the fight against FETO. In this study, it is analyzed how FETÖ established the identity of a female militant, which it initially ignored but discovered later. Firstly, the historical perspective of FETO on female identity is discussed. Afterwards, it is focused on why the elder sisterhood system and the catalog marriage system were established, and finally, the importance of combating FETO's militant female identity is mentioned.
