Rosa Parks became one of the major symbols of the civil rights movement after she was arrested in Montgomery, Alabama, for refusing to give up her seat to a white passenger in 1955. For 381 days, African-Americans boycotted public transportation to protest Parks' arrest and, in turn, segregation laws. The boycott led to a Supreme Court ruling desegregating public transportation in Montgomery. In this photo, Parks rides the bus a day after the Supreme Court ruling in 1956.
