It was on December 1, 1955 that Rosa made her famous stand (while sitting) on the bus. Rosa had settled in her seat on the bus after a hard days work. All the seats on the bus had filled up when a white man boarded. The bus driver told Rosa and some other African-Americans to stand up. Rosa refused. The bus driver said he would call the police. Rosa didn't move. Soon the police showed up and Rosa was arrested.
