Juneteenth (a portmanteau of June and nineteenth) – also known as Freedom Day, Jubilee Day, Liberation Day, and Emancipation Day – is a holiday celebrating the emancipation of those who had been enslaved in the United States. Originating in Galveston, Texas, it is now celebrated annually on the 19th of June throughout the United States, with varying official recognition. It is commemorated on the anniversary date of the June 19, 1865 announcement by Union Army general Gordon Granger, proclaiming freedom from slavery in Texas.

President Abraham Lincoln's Emancipation Proclamation had officially outlawed slavery in Texas and the other states in rebellion against the Union almost two and a half years earlier. Enforcement of the Proclamation generally relied on the advance of Union troops. Texas being the most remote of the slave states had a low presence of Union troops as the American Civil War ended; thus enforcement there had been slow and inconsistent before Granger's announcement. Although Juneteenth generally celebrates the end of slavery in the United States, it was still legal and practiced in two Union border states (Delaware and Kentucky) until later that year when ratification of the Thirteenth Amendment to the Constitution abolished chattel slavery nationwide in December.
