Claudette Colvin: The 15-year-old who came before Rosa Parks

In March 1955, nine months before Rosa Parks defied segregation laws by refusing to give up her seat to a white enger on a bus in Montgomery, Alabama, 15-year-old Claudette Colvin did exactly the same thing. Eclipsed by Parks, her act of defiance was largely ignored for many years. She herself didn't talk about it much, but she spoke recently to the BBC.

"There was segregation everywhere. The churches, buses and schools were all segregated and you couldn't even go into the same restaurants," Claudette Colvin says.

"I during Easter one year, I was to get a pair of black patent shoes but you could only get them from the white stores, so my mother drew the outline of my feet on a brown paper bag in order to get the closest size, because we weren't allowed to go in the store to try them on."

Going to a segregated school had one advantage, she found - her teachers gave her a good grounding in black history.

"We learned about negro spirituals and recited poems but my social studies teachers went into more detail," she says.

"They lectured us about Harriet Tubman and Sojourner Truth and we were taught about an opera singer called Marian Anderson who wasn't allowed to sing at Constitutional Hall just because she was black, so she sang at Lincoln Memorial instead."

On 2 March 1955, Colvin and her friends finished their classes and were let out of school early.

"We walked downtown and my friends and I saw the bus and decided to get on, it was right across the road from Dr Martin Luther King's church," Colvin says.

"The white people were always seated at the front of the bus and the black people were seated at the back of the bus. The bus driver had the authority to assign the seats, so when more white engers got on the bus, he asked for the seats."

The problem arose because all the seats on the bus were taken. Colvin and her friends were sitting in a row a little more than half way down the bus - two were on the right side of the bus and two on the left - and a white enger was standing in the aisle between them.

The driver wanted all of them to move to the back and stand so that the white enger could sit.

"He wanted me to give up my seat for a white person and I would have done it for an elderly person but this was a young white woman. Three of the students had got up reluctantly and I remained sitting next to the window," she says.

Under the twisted logic of segregation the white woman still couldn't sit down, as then white and black engers would have been sharing a row of seats - and the whole point was that white engers were meant to be closer to the front.

But Colvin told the driver she had paid her fare and that it was her constitutional right to remain where she was.

"Whenever people ask me: 'Why didn't you get up when the bus driver asked you":[]}
