High-profile opposition to the Vietnam war turned to street protests in an effort to turn U.S. political opinion against the war. The protests gained momentum from the Civil Rights Movement that had organized to oppose segregation laws, which had laid a foundation of theory and infrastructure on which the anti-war movement grew. Protests were fueled by a growing network of independently published newspapers (known as "underground papers") and the timely advent of large venue rock'n'roll festivals such as Woodstock and Grateful Dead shows, attracting younger people in search of generational togetherness.
