Rosa Parks was born in Alabama in 1913. She became involved with the civil rights movement, joining the Montgomery chapter of the NAACP in 1943. In December 1955, she boarded a bus in downtown Montgomery, and refused to give up her seat to a white person onboard. She was arrested. Her actions instigated the Montgomery Bus Boycott, a seminal event in the civil rights movement. This eventually led to a United States Supreme Court decision that declared the Alabama and Montgomery laws that segregated buses were unconstitutional. Rosa Parks remained politically active until her death in 2005.
