As the bus Rosa was riding continued on its route, it began to fill with white passengers. Eventually, the bus was full and the driver noticed that several white passengers were standing in the aisle. He stopped the bus and moved the sign separating the two sections back one row and asked four black passengers to give up their seats. Three complied, but Rosa refused and remained seated. The driver demanded, "Why don't you stand up?" to which Rosa replied, "I don't think I should have to stand up." The driver called the police and had her arrested. Later, Rosa recalled that her refusal wasn't because she was physically tired, but that she was tired of giving in.Read the biography and watch the video.
