The document discusses the importance of the Montgomery Bus Boycott. It began in 1955 when Rosa Parks was arrested for refusing to give up her seat to a white passenger on a segregated bus in Montgomery, Alabama. In response, African American leaders organized a boycott of the bus system that lasted over a year. The boycott demonstrated the power of nonviolent protest and economic impact. It ultimately led to a Supreme Court ruling that declared segregated buses unconstitutional, thereby helping to strengthen the civil rights movement across the United States.
