Rosa Parks refusal to give up her seat to a white male on a bus in Montgomery, Alabama during the 1950's helped spark the Montgomery Bus Boycott. African-American citizens all over the city refused to take public transporation until the policy of forcing blacks to sit in the back of the bus was changed. This action by Rosa Parks helped fuel this movement and resulted in the Montgomery bus companies to lose a significant amount of revenue. After roughly a year of boycotting, the city of Montgomery changed their policy.
