On this Martin Luther King Day, Americans are remembering the civil rights leader's fight for the poor, commemorating his service and sacrifice.

In October 1962, Reverend King addressed students on campus at the Harvard Law School forum. He talked about the future of - and struggle for - integration.

“We’ve been able to say to our bitterest and most violent opponents, ‘We will match your capacity to inflict suffering by our capacity to endure suffering,’” King said.

Two years later, in 1964, King was awarded the Nobel Peace Prize for his nonviolent resistance to racial and economic prejudice. At 35, as the youngest recipient of the award, he then donated his winnings to the civil rights movement.
