The New Left was a broad political movement that emerged from the counterculture of the 1960s and continued through the 1970s. It consisted of activists in the Western world who campaigned for a broad range of social issues such as feminism, gay rights, drug policy reforms and the rejection of traditional family values, social order, and gender roles. The New Left differs from the traditional left in that it tended to acknowledge the struggle for various forms of social justice, whereas previous movements prioritized explicitly economic goals. However, many have used the term "New Left" to describe an evolution, continuation, and revitalization of traditional leftist goals.

Herbert Marcuse was a German-American philosopher, social critic, and political theorist, associated with the Frankfurt School of critical theory. Born in Berlin, Marcuse studied at the Humboldt University of Berlin and then at Freiburg, where he received his PhD. He was a prominent figure in the Frankfurt-based Institute for Social Research – what later became known as the Frankfurt School. In his written works, he criticized capitalism, modern technology, Soviet Communism, and popular culture, arguing that they represent new forms of social control.
