The Catonsville Nine refers to a group of nine Catholic activists who protested the Vietnam War in 1968. They gained attention for burning draft files in Catonsville, Maryland, as a form of civil disobedience against the U.S. government's military actions. Their actions were intended to highlight the moral implications of the war and the draft. The group included notable figures such as Daniel Berrigan, a Jesuit priest, and his brother Philip Berrigan, a former priest and anti-war activist. Their trial and subsequent convictions sparked national debate about the war, civil disobedience, and the role of religion in political activism.
