The Woodstock Festival was a pivotal music festival held in August 1969, symbolizing the peak of the counterculture movement and anti-war sentiment in the United States. It gathered over 400,000 attendees for a three-day celebration of peace, love, and music, featuring iconic performances by artists such as Jimi Hendrix and Janis Joplin. The event became a lasting symbol of the youth rebellion against the Vietnam War and societal norms.
