In 1955, Rosa Parks was an African-American living in Montgomery, Alabama -- a city with laws that strictly segregated blacks and whites. On 1 December 1955, after her day of work as a seamstress at a local department store, Parks boarded a city bus. When she refused to give up her seat to a white man, the bus driver called police, and Parks was arrested and fined. The resulting bus boycott by African-Americans, led by Reverend Martin Luther King, Jr., caused a national sensation. The boycott was a success and led to desegregation in Montgomery and elsewhere in the United States.
