The bus driver wanted four people to stand up. They didn't move. The driver said, "Let me have those seats." Three people moved. One did not.
Rosa Parks lived in Alabama. In the 1950s, there was a law. It said that black and white people could not be together. They could not eat at the same tables in restaurants. They could not use the same restrooms. They could not go to the same schools. They could not sit together on buses. The white people sat in the front of the bus. The black people had to sit in the back. If told to, a black person had to give up his or her seat to a white person.
On December 1, 1955, Rosa Parks rode a public bus. It was crowded. All of the white seats were taken. Rosa Parks was told to give up her seat when another white person got on the bus. She did not. She said, "I don't think I should have to stand up." The driver called the police. Rosa Parks was taken to jail.
