Acting on James Bevel's call for a march from Selma to Montgomery, King, Bevel, and the SCLC, in partial collaboration with SNCC, attempted to organize the march to the state's capital. The first attempt to march on March 7, 1965, was aborted because of mob and police violence against the demonstrators. This day has become known as Bloody Sunday and was a major turning point in the effort to gain public support for the civil rights movement.
