Rosa Parks died last night. She will always be remembered as the catalyst for the Montgomery bus boycott. By refusing to leave her seat on December 1, 1955, Mrs. Parks infused courage into millions of African-Americans who were tired of being treated as second-class citizens. And because of the Montgomery bus boycott, the world was introduced to a young pastor named Martin Luther King, Jr. Never before has one’s refusal to act made such an impact on individual and national attitudes about race and justice.
