Rosa Louise McCauley Parks (February 4, 1913 – October 24, 2005) was an African-American civil rights activist, whom the U.S. Congress called "the first lady of civil rights" and "the mother of the freedom movement". Her birthday, February 4, and the day she was arrested, December 1, have both become Rosa Parks Day, commemorated in the U.S. states of California and Ohio.
On December 1, 1955, in Montgomery, Alabama, Parks refused to obey bus driver James F. Blake's order that she give up her seat in the colored section to a white passenger, after the white section was filled. Parks was not the first person to resist bus segregation. Others had taken similar steps in the twentieth century, including Irene Morgan in 1946, Sarah Louise Keys in 1955, and the members of the Browder v. Gayle lawsuit (Claudette Colvin, Aurelia Browder, Susie McDonald, and Mary Louise Smith) arrested months before Parks. NAACP organizers believed that Parks was the best candidate for seeing through a court challenge after her arrest for civil disobedience in violating Alabama segregation laws though eventually her case became bogged down in the state courts.
