In the spring of 1963, activists in Birmingham, Alabama launched one of the most influential campaigns of the Civil Rights Movement: Project C, better known as The Birmingham Campaign. It would be the beginning of a series of lunch counter sit-ins, marches on City Hall and boycotts on downtown merchants to protest segregation laws in the city.
