While coming back from work in Montgomery, Alabama, Rosa Parks, 42 at the time, refused to give up her seat for a white man in a city bus. The driver of the bus, a man named James F. Blake, demanded that she vacate a row of four seats in the "colored" section to let a White passenger sit, since the "White" section had already filled up. She was arrested and briefly jailed for not complying with the city’s ordinance according to which Black people had to sit at the back of the bus and leave their seat to Whites. Her action set off a boycott of the city’s bus system.
