The 1960s counterculture challenged the mainstream practices that dominated the 1950s, producing such groups as the hippies, Diggers, the National Organization for Women, and the American Indian Movement, all of which demanded societal change. The A–Z entries in this volume provide fascinating details on notable persons who stirred alternative ideas such as Betty Friedan, Abbie Hoffman, Andy Warhol, and Stokely Carmichael; events such as Woodstock, the Moratorium, and various be-ins; and new directions in music, art, clothing, and language.
