The Birmingham campaign
Birmingham campaign
The Birmingham campaign, also known as the Birmingham movement or Birmingham confrontation, was a movement organized in early 1963 by the Southern Christian Leadership Conference (SCLC) to bring attention to the integration efforts of African Americans in Birmingham, Alabama.

Led by Martin Luther King Jr., James Bevel, Fred Shuttlesworth and others, the campaign of nonviolent direct action culminated in widely publicized confrontations between young black students and white civic authorities, and eventually led the municipal government to change the city's discrimination laws.

Birmingham campaign [SEP] Introduction
Black citizens faced legal and economic disparities, and violent retribution when they attempted to draw attention to their problems. Martin Luther King Jr. called it the most segregated city in the country. Protests in Birmingham began with a boycott led by Shuttlesworth meant to pressure business leaders to open employment to people of all races, and end segregation in public facilities, restaurants, schools, and stores. When local business and governmental leaders resisted the boycott, SCLC agreed to assist. Organizer Wyatt Tee Walker joined Birmingham activist Shuttlesworth and began what they called Project C, a series of sit-ins and marches intended to provoke mass arrests.
