Why was emmett till see as the spark of the civil rights movement

Emmett Till's murder was a spark in the upsurge of activism and resistance that became known as the Civil Rights movement. The sight of his brutalized body pushed many who had been content to stay on the sidelines directly into the fight. Emmett Till's death had a powerful effect on Mississippi Civil Rights activists. Medgar Evers, then an NAACP field officer in Jackson, Mississippi, urged the NAACP national leadership to get involved, and along with NAACP field workers Ruby Hurley and Amzie Moore, conducted a secret search for black witnesses willing to take the serious risk to come forward.
