This papper deals with the role of women in civilian-millitary missions of NATO. The research question is: „Are women, within the NATO alliance, underrepresented in relation to men, in promoting peace and security?“. For centuries, women have been considered as housewives and their experience with war and international peace programme was neglected. However, war affects women and men in various ways, so their experience of war is different. Women are extremely important for the decision-making process of building and maintaining peace, as these decisions concern them and their future generations. The adoption of Resolution 1325 and its implementation in the NATO system, as well as in the national policies of member states and partner countries, has allowed the advancement of women's role in the security domain. NATO has made a great effort to improve the rights and position of women. During 16 years, in NATO, the number of women increased by 3.2%, reflecting the further subdivision of women. Although, it was expected a larger percentage, it should be noticed that this is still an institution primarly based on the man's power and dominance. Therefore, this percentage is a remarkable improvement and an encuragement for further work on gender politics.
