The methods of the Civil Rights Movement changed significantly from the mid-1960's onwards. Some civil rights leaders such as Martin Luther King wanted to continue to protest peacefully while other groups began to use violence. The Nation of Islam, a religious organization which provoked controversy, was one group which wished to use violent tactics. The group, led by Malcolm X, spread the message of black pride, self-sufficiency, and self-defense. These goals stood in stark contrast to the goals of the pre-1960's Civil Rights Movement. SNCC, which ironically stood for Student Nonviolent Coordinating Committee, also began to use violence. Stokely Carmichael, who had replaced John Lewis as the head of SNCC, clashed with Martin Luther King. While both participating in the March Against Fear, Martin Luther King wanted to proceed peacefully while Carmichael wanted to resist hostile state troopers. Also while participating in the March Against Fear, SNCC rallied the crowds with a new slogan "Black Power!"
The goals of the Civil Rights Movement also changed significantly from the mid-1960's onwards. African-American leaders such as Martin Luther King realized that the American South was not the only place change was needed. So, Martin Luther King and the SCLC traveled to Chicago to try to improve housing, jobs, and schools for the city's black residents. The group began their efforts by tackling slums, an area which was home to many blacks. However, Chicago Mayor Richard J. Daley used his "political machine" to prevent the protesters from gaining any ground. After six months of little progress, activists stopped their protests in the slums and moved their efforts to white areas that excluded blacks. Angry white mobs attacked the protesters. Another SCLC organizer, Jesse Jackson, led a march in Cicero, Illinois. Cicero was known for its racial hatred, and leaders on both sides had to call a summit to prevent rioting. Martin Luther King then announced that there would not be any more riots and leaves the city soon after, having few problems resolved.
