Juneteenth (June 19) is a United States federal holiday that celebrates the emancipation of enslaved black Americans. On June 19, 1865, Union General Gordon Granger arrived in Galveston, Texas. He informed the enslaved African Americans of their freedom and that the Civil War had ended. This momentous occasion has been celebrated as Juneteenth — a combination of June and 19 — for over 150 years.
In 1919, the National Association for the Advancement of Colored People (NAACP) dubbed "Lift Every Voice and Sing" the "Negro national anthem."
