On September 15, 1963, an explosion shattered the quiet of a Sunday morning, blowing apart the 16th Street Baptist Church in Birmingham, Alabama. Four young girls who were getting ready for Sunday School were killed almost instantly. Denise McNair, 11, Addie Mae Collins, 14, Carole Robertson, 14, and Cynthia Wesley, 14 died as a result of a bomb placed under the church by members of the Ku Klux Klan.
