Local residents attend a celebration to mark Juneteenth, the traditional commemoration date of the emancipation of enslaved people in the United States at Leimert Park, in Los Angeles on June 19, 2021.
Juneteenth is the first national holiday established since Martin Luther King Jr. Day in 1983.
It came after the summer of 2020 saw nationwide protests spurred by the police killings of George Floyd, Breonna Taylor, and others.
