Young Activists Take Center Stage at March on Washington Leslie Bonilla When the son of famed civil rights activist Martin Luther King Jr. took to the stage in Washington on Friday -- 57 years after his father's famous "I Have a Dream" address -- he stepped aside for yet another King. "I am so honored to be here," Martin Luther King III said while standing at the Lincoln Memorial. "But before I say something, I want you to hear from the future of our nation." Wearing a bright teal headband and a black-and-white dress, 12-year-old Yolanda Renee King adjusted the microphone lower and glanced sideways at her father, smiling nervously. The younger King launched into her second major address to thousands of marchers in the U.S. capital. Her first was two years ago, at a rally against gun violence, organized by high school survivors of a mass shooting that drew hundreds of thousands to Washington. "Two years ago, at the March for Our Lives, I said, 'Spread the word! Have you heard all across the nation, we're going to be a great generation!'" Yolanda recalled. She called on young activists to be "the generation that dismantles systemic racism once and for all, now and forever." Friday's protest follows months of national unrest in response to recent deaths of Black Americans that are being questioned as racist. George Floyd died while in police custody in Minneapolis, Minnesota, in May. More recently, Jacob Blake was shot by police August 23 in Kenosha, Wisconsin. In between, have been months of domestic and international protests. Floyd cried out as a police officer knelt on his neck, "I can't breathe," echoing Eric Garner, who died in New York City in 2014, gasping the same words. Friday's Get Your Knee Off Our Necks Commitment March on Washington was organized largely by the Rev. Al Sharpton and the civil rights organization he founded in 1991, the National Action Network. But the event was a passing of the baton for some youth activists. "We are the great dreams of our grandparents, great grandparents and all our ancestors," Yolanda said. "We stand and march for love, and we will fulfill my grandfather's dream." Sakira Coleman, the 23-year old co-founder of the activist group Until Freedom, told the BBC that she would attend Friday's march, 57 years after her grandmother participated in the original march on Washington. .
