Rosa Parks refused to give up her seat on a bus to a white passenger in 1955, which led to her arrest and imprisonment. Her act of civil disobedience sparked the Montgomery Bus Boycott and helped launch the modern U.S. civil rights movement. One year later, the Supreme Court ruled that segregation on public buses was unconstitutional, cementing Parks' role in fighting for equal rights.
