What would you do if you were not allowed to sit where you wanted to on a bus? It used to be that in Southern towns African Americans could not sit with whites on public transportation. In December 1955, an African American woman named Rosa Parks was arrested after she refused to move to the black seating section at the back of a public bus in Montgomery, Alabama. To protest this treatment of African Americans, a group led by Martin Luther King, Jr. organized a boycott of Montgomery's public buses. African Americans refused to ride public buses and instead walked or shared rides to get where they needed to go. After a year, the city finally changed the law forcing African Americans to sit at the back of buses.
