Some who self-identified as "New Left" (especially those drawing from Trotskyism)[5] rejected involvement with the labor movement and Marxism's historical theory of class struggle,[6] although others gravitated to their own takes on established forms of Marxism such as the New Communist movement (which drew from Maoism) in the United States or the K-Gruppe in the German Sprachraum. In the United States, the movement was associated with the anti-war college-campus protest movements, including the Free Speech Movement.
