The Montgomery Bus Boycott was a protest against segregation on public buses that lasted 381 days from December 5, 1955 to December 20, 1956. It was sparked when Rosa Parks was arrested for refusing to give up her seat to a white passenger. Local NAACP leader E.D. Nixon and WPC leader Jo-Ann Robinson helped organize the boycott by printing and distributing flyers. Over 35,000 flyers announced the boycott. Supporters organized carpools to drive people instead of using the buses. The boycott ended with new laws being passed ending segregation on buses.
