Protesters march in a Black Lives Matter demonstration organized by the Dallas Black Firefighters Association on Juneteenth 2020 in Dallas, Friday, June 19, 2020. Juneteenth marks the day in 1865 when federal troops arrived in Galveston, Texas to take control of the state and ensure all enslaved people be freed, more than two years after the Emancipation Proclamation. Former President Abraham Lincoln first issued the Emancipation Proclamation on Sept. 22, 1862, and it became effective the following Jan. 1. Word didnt reach the last enslaved black people until June 19 of that year, when Union soldiers brought the news of freedom to Galveston, Texas. Kristi Noem proclaimed Friday as Juneteenth Day, but the proclamation does not make the day a state-recognized holiday.
