Queer studies, sexual diversity studies, or LGBTQ studies is the study of topics relating to sexual orientation and gender identity usually focusing on lesbian, gay, bisexual, transgender, gender dysphoric, asexual, aromantic, queer, questioning, and intersex people and cultures.
Originally centered on LGBT history and literary theory, the field has expanded to include the academic study of issues raised in archaeology, sociology, psychiatry, anthropology, the history of science, philosophy, psychology, sexology, political science, ethics, communication, and other fields by an examination of the identity, lives, history, and perception of being queer.
