Rosa Parks was arrested in 1955 for refusing to give up her seat to a white man on a bus in Montgomery, Alabama, sparking the Montgomery Bus Boycott led by Dr. Martin Luther King Jr. Over 382 days, 17,000 black residents walked or carpooled to work in protest of bus segregation laws. This first large-scale nonviolent demonstration led to the Supreme Court declaring bus segregation unlawful in 1956. Dr. King went on to lead the Civil Rights movement and its goal of nonviolent protest until his assassination in 1968.
