(CNN) - A surprise guest appeared at the March for Our Lives in Washington on Saturday to tell the crowd about a dream her grandfather had.

"My grandfather had a dream that his four little children will not be judged by the color of their skin, but by the content of their character," said 9-year-old Yolanda Renee King, the eldest granddaughter of Martin Luther King Jr.

"I have a dream that enough is enough," King added. "And that this should be a gun-free world, period."

King then led the massive crowd in a chant, cheering, "Spread the word! Have you heard? All across the nation, we are going to be a great generation!"
