During the early 1970s, influenced by the U.S. gay liberation movement and the 1968 Tlatelolco massacre, small political and cultural groups were formed. Initially, they were strongly linked to the political left and, to a degree, feminist organizations. One of the first LGBT groups in Latin America was the Homosexual Liberation Front ("Frente de Liberación Homosexual"), organized in 1971 in response to the firing of a Sears employee because of his allegedly homosexual behavior in Mexico City.
