i accept the nobel prize for peace at a moment when 22 million negroes of the
united states of america are engaged in a creative battle to end the long night of
racial injustice, i accept this award on behalf of a civil rights movement which is
moving with determination and a majestic scorn for risk and danger to establish a
reign of freedom and a rule of justice. i am mindful that only yesterday in
birmingham, alabama, our children, crying out for brotherhood, were answered
with fire hoses, snarling dogs and even death. i am mindful that only yesterday in
philadelphia, mississippi, young people seeking to secure the right to vote were
brutalized and murdered. and only yesterday more than 40 houses of worship in
the state of mississippi alone were bombed or burned because they offered a
sanctuary to those who would not accept segregation. i am mindful that debilitating
and grinding poverty afflicts my people and chains them to the lowest rung of the
economic ladder.
therefore, i must ask why this prize is awarded to a movement which is
beleaguered and committed to unrelenting struggle; to a movement which has not
won the very peace and brotherhood which is the essence of the nobel prize.
