A day after delivering his famous "I've Been to the Mountaintop" sermon, King was assassinated on April 4, 1968. Riots broke out in more than 110 cities across the United States in the days that followed, notably in Chicago, Baltimore, and in Washington, D.C. The damage done in many cities destroyed black businesses.
The day before King's funeral, April 8, Coretta Scott King and three of the King children led 20,000 marchers through the streets of Memphis, holding signs that read, "Honor King: End Racism" and "Union Justice Now". National Guardsmen lined the streets, perched on M-48 tanks, bayonets mounted, with helicopters circling overhead. On April 9 Mrs. King led another 150,000 in a funeral procession through the streets of Atlanta. Her dignity revived courage and hope in many of the Movement's members, cementing her place as the new leader in the struggle for racial equality.
