Parks joined the Montgomery chapter of the NAACP in 1943 and became the organization's secretary. In the summer of 1955, she attended a workshop designated to promote integration by giving students the experience of interracial living.
On December 1, 1955, Rosa Parks refused to obey a bus driver`s order that she give up her seat to make room for a white passenger. The act became an important symbol of the Modern Civil Rights Movement and Parks became an international icon of resistance to racial segregation. She organized and collaborated with civil rights leaders, including Martin Luther King Jr., helping to launch him to national prominence in the civil rights movement.
Parks resided in Detroit until she died of natural causes at the age of 92 on October 24, 2005.
