Read the excerpt from "Freedom Walkers” by Russell Freedman.Two youngsters from New Jersey—sixteen-year-old Edwina Johnson and her brother Marshall, who was fifteen—arrived in Montgomery to visit relatives during the summer of 1949. No one told them about the city’s segregation laws for buses, and one day they boarded a bus and sat down by a white man and boy.The white boy told Marshall to get up from the seat beside him. Marshall refused. Then the bus driver ordered the black teenagers to move, but they continued to sit where they were. Up North, they were accustomed to riding integrated buses and trains. They didn’t see now why they should give up their seats.
