The fight to end the segregation and injustice of the Jim Crow system was a long one. During the Civil Rights era, people summoned courage by forming grassroots organizations that were often formed at local churches. For example, the Montgomery Bus Boycott of 1955-56 was organized after Rosa Parks, an African American seamstress and member of the NAACP, refused to give up her seat in a white section of a segregated city bus in Montgomery, Alabama. The movement coalesced around a young preacher named Dr. Martin Luther King Jr., and meetings were held at his church. The leadership of the movement, along with the example of Rosa Parks, helped people summon courage, as King was a dynamic speaker who was able to rally the population of Montgomery to stay off the buses during the boycott. He was helped by a series of local organizers, and the leadership and grassroots nature of the movement helped provide people with courage and strength.
