Parks was a seamstress in Alabama and a civil rights activist, but she said after the incident that she had not pre-planned it. She was convicted of violating a law mandating segregation on city buses and fined. She appealed as civil rights activists organized a boycott of Montgomery buses — coordinated by the Montgomery Improvement Association of which a 26-year-old minister named Martin Luther King Jr. was president — that lasted 13 months. It ended when the Supreme Court ruled that it was unconstitutional to require segregation on public buses.
Rosa Parks became known as “the mother of the civil rights movement.”
