Deriving its name from combiningJune and nineteenth, it is celebrated on the anniversary of the order by Major General Gordon Grangerproclaiming freedom for enslaved people in Texas on June 19, 1865 (two and a half years after the Emancipation Proclamationwas issued).^[7] Originating in Galveston, Juneteenth has since been observed annually in various parts of the United States, often broadly celebrating African-American culture. The day was first recognized as a federal holiday in 2021, when President Joe Biden signed the Juneteenth National Independence Day Act into law after the efforts of Lula Briggs Galloway, Opal Lee, and others.”
