The document discusses counterculture movements that emerged in the United States during the 1960s. The counterculture movement gained momentum in opposition to social and political conservatism, especially as the Vietnam War intensified. New forms of cultural expression developed during this time, including pop music pioneered by bands like the Beatles. Symbols like the peace sign came to represent the anti-war sentiments of the counterculture. Artistic styles like tie-dye clothing and batik textiles also became closely associated with the hippie youth movement of the 1960s.
