Since the sixteenth century, the word queer has meant “perverse” in English. The term spread in the United States in the late twentieth century to criticize and render obsolete both gender (man/woman) and sexual (homosexuality/heterosexuality) binarism through an analysis of their diversity. Its emergence on the European continent dates back to the 1990s, expressing itself within academia (through diverse publications of queer theory) and through the emergence of social movements distinguishing themselves from the traditional lesbian, gay, bisexual, and transgender (LGBT) movement. Queers in Europe created numerous national organizations reflecting the context of each country, notably in their relations with the LGBT movement, in addition to a perceptible transnational dynamic with respect to theoretical explorations and common European demonstrations.
