The Montgomery Bus Boycott was a protest against segregation on public buses in Montgomery, Alabama, from 1955-1956. It was sparked by the arrest of Rosa Parks, an African American woman who refused to give up her seat to a white passenger on a city bus. The boycott was organized by local civil rights leaders, including Martin Luther King Jr., and lasted for over a year. African Americans in Montgomery refused to ride the buses and instead carpooled, walked, or used other means of transportation. The boycott faced fierce resistance from segregationist authorities but ultimately resulted in the U.S. Supreme Court ruling that segregation on public buses was unconstitutional.
