Rosa Parks was a civil rights icon who is best known for her refusal to give up her seat on a bus in Montgomery, Alabama in 1955. This act of civil disobedience sparked the Montgomery Bus Boycott and helped to launch the civil rights movement. She was arrested and convicted for violating the segregation laws, but her actions were seen as a symbol of resistance to racial injustice. She continued to be an advocate for civil rights throughout her life, and her legacy lives on today.
