This paper presents a gender analysis of the United Nations Security Council Resolution 1820(2008), the International Human Rights Law and the International Humanitarian Law. The study is regarding resolution 1820 as a breakthrough in the writings of legal documents that criminalizes sexual violence against women in internal armed conflict. Using textual analysis and a feminist theoretical approach the study highlights the construction of gender norms in the legal document. The study suggests that the narrative of legislative bodies of the IHL and IHRL is dominated by masculinity. Furthermore I am discussing if such norms are evident as a form of essentialism in the legal document, if essentialism is apparent in local and international juridical systems, and what effect does it have on the resolution 1820.
