The anti-war movement of the 1960s was a significant sociopolitical phenomenon in the United States, primarily opposing the Vietnam War. As the conflict escalated, public sentiment shifted, especially among younger Americans who questioned the government's intentions and the morality of U.S. involvement. This movement was characterized by protests, demonstrations, and a cultural shift that emphasized peace and civil rights. Prominent events included the Kent State shootings and the Woodstock festival. The anti-war sentiment resulted in a broader critique of U.S. government policies and helped shift public opinion, ultimately influencing U.S. withdrawal from Vietnam.
