On 26 March 1966, large-scale protests against the Vietnam War erupted across the United States, with thousands gathering in cities like New York, Washington, DC, and Chicago.
Fueled by rising casualties, conscription, and growing disillusionment with US involvement in Southeast Asia, demonstrators from all walks of life—students, activists, and veterans—voiced their opposition through marches, rallies, and acts of civil disobedience.
These protests marked a turning point in the anti-war movement, signalling the beginning of widespread public dissent that would intensify in the years to come.
