Rosa Parks died this week aged 92.
She was famous for helping to spark the US civil rights movement in the 1950s.
In December 1955 she refused to give up her seat on a city bus to a white passenger. The bus driver had her arrested. She was tried and convicted.
Her action inspired millions and led to a citywide boycott of the bus system that lasted more than a year.
The boycott was led by Martin Luther King. It was the first mass act of the movement that went on to end racial segregation laws in the South of the US.
Socialist Worker will run a full obituary of Rosa Parks in next week’s issue.
