A boycott is an organized refusal by people to deal with a person or group in order to reach a certain goal. An example is the famous boycott that began in 1955 when Mrs. Rosa Parks of Montgomery, Alabama, refused to obey a law requiring black people to sit at the back of city buses. Mrs. Parks was arrested, and her arrest sparked a boycott of the city bus system by African Americans. The boycott was organized and led by Dr. Martin Luther King, Jr. Rather than continue to lose money needed to run the bus system, the city changed the law.
