Claudette Colvin, born on September 5, 1939, is a significant figure in the American civil rights movement. She is renowned for her pivotal role in the Montgomery Bus Boycott of 1955, where she refused to give up her seat on a segregated bus in Montgomery, Alabama, at the age of 15. This act of defiance was one of the first steps leading to the historic Supreme Court decision in Brown v. Board of Education.
