Read the excerpt from Freedom Walkers by Russell Freedman.

No one moved. Blake rose from the driver’s seat and called out again: "Y’all better make it light on yourselves and let me have those seats.” Reluctantly, three of the black passengers rose and moved to the back. Rosa Parks shifted slightly to allow the man next to her to get up, but she did not move from her seat. She wasn’t sitting in the white section, and she didn’t think that she should have to give up her seat and stand in the aisle the rest of the way home. She had just spent the entire day tailoring and pressing clothes for white folks.
