Rosa Parks was an African American civil rights activist born in 1913 who refused to give up her seat to a white passenger on a segregated bus in Montgomery, Alabama in 1955. Her arrest sparked the Montgomery Bus Boycott, a 381-day boycott of the bus system that ultimately led to the Supreme Court ruling segregation on public buses unconstitutional. Parks went on to work for civil rights and received numerous honors for her pivotal role in launching the modern civil rights movement.
