Maj. Gen. Gordon Granger of the Union Army announced to the assembled crowd at Ashton Villa in Galveston, Texas, "In accordance with a proclamation from the Executive of the United States, all slaves are free."

It was June 19, 1865.

Never mind that President Abraham Lincoln's Emancipation Proclamation had been written and read more than two years earlier. Juneteenth, named for the June 19 declaration, started as a celebration of emancipation day in Texas and eventually spread to other states. With celebrations dating back to 1866, Juneteenth now commemorates the end of slavery in the United States.
