Document 6: Civil rights movement: SNCC had undertaken an ambitious voter registration program in Selma, Alabama, in 1963, but by 1965 little headway had been made in the face of opposition from Selma's sheriff, Jim Clark. After local residents asked the SCLC for assistance, King came to Selma to lead several marches, at which he was arrested along with 250 other demonstrators. The marchers continued to meet violent resistance from police. Jimmie Lee Jackson, a resident of nearby Marion, was killed by police at a later march in February 17, 1965. Jackson's death prompted James Bevel, director of the Selma Movement, to initiate and organize a plan to march from Selma to Montgomery, the state capital.
Document 7: Civil rights movement: The movement was characterized by major campaigns of civil resistance.

The lynching of Emmett Till and the visceral response to his mother's decision to have an open - casket funeral mobilized the African - American community nationwide. Forms of protest and / or civil disobedience included boycotts such as the successful Montgomery Bus Boycott (1955 -- 56) in Alabama; ``sit - ins ''such as the influential Greensboro sit - ins (1960) in North Carolina and successful Nashville sit - ins in Tennessee; marches, such as the Birmingham Children's Crusade and Selma to Montgomery marches (1965) in Alabama; and a wide range of other nonviolent activities.
