Rosa Parks first came to national prominence as a civil rights activist when, on December 1, 1955, she refused to give up her seat on a Montgomery, Alabama, city bus to a white man. Her refusal to get up led to her arrest. On the day of her conviction, December 5, 1955, leaflets were spread across Montgomery urging African-Americans to stay off the buses. At enormous personal sacrifice, African Americans maintained the bus boycott for a total of 381 days, severely damaging the bus company's finances. Ultimately, bus segregation of the sort practiced in Montgomery was ruled unconstitutional by a federal court and Montgomery rescinded its racist law.
