Explanation:

The Montgomery bus boycott was a political and social boycott that took place between 1955 and 1956 in Montgomery, Alabama, to oppose the city's policy of racial segregation. Many people were known to the movement, such as Martin Luther King Jr., Rosa Parks, and others. The move caused high deficits in Montgomery's public transportation system because a large percentage of people using public transportation stopped using it. The effort stretched from December 1, 1955 to December 20, 1956 and led to a decision by the United States Supreme Court stating the legal requirements of segregation on buses in the state of Alabama and the city of Montgomery unconstitutional
