During the 1960s, a counterculture movement emerged among mostly white, middle-class youth who called themselves hippies. Disillusioned with mainstream society, hippies embraced peace, love, and harmony through rock music, drugs like LSD and marijuana, colorful clothing, and alternative religions. Thousands left traditional lifestyles to live communally. However, many hippies struggled without structure and support from mainstream society. The 1960s also saw a rise in pop art by artists like Andy Warhol and the popularity of rock bands like the Beatles. In 1969, the Woodstock music festival drew 400,000 people to see famous bands of the era.
