Abstract   In civil and ethnic conflict, sexual minorities experience a heightened risk for war crimes such as sexual violence, torture, and death. As a result, sexual minorities remain an invisible population in armed conflict out of a need for safety. Further study of sexual minorities in conflict zones confronts matters of human rights, war crimes, and the psychosocial effects of war. This article reviews the existing research on sexual minorities in conflict zones, examines the findings on human rights, war crimes, and the psychosocial effects of war and violence on sexual minority populations, and reviews the barriers to effectiveness faced by intervention programs developed specifically to aid post-conflict societies. The article concludes with a summary of findings within the literature and further considerations for research on aggression and violent behavior with sexual minority groups in conflict zones.
