Queer is an umbrella term for people who are not heterosexual or are not cisgender. Originally meaning 'strange' or 'peculiar', queer came to be used pejoratively against LGBT people in the late 19th century. Beginning in the late 1980s, queer activists, such as the members of Queer Nation, began to reclaim the word as a deliberately provocative and politically radical alternative to the more assimilationist branches of the LGBT community.
