On **June 19, 1865**, when Union troops arrived in Galveston, Major General Gordon Granger delivered General Order No. 3, which said: "The people of Texas are informed that, in accordance with a proclamation from the Executive of the United States, all slaves are free. This involves an absolute equality of personal rights and rights of property between former masters and slaves." 

The day of June 19th, or Juneteenth as it was later called, became a national holiday marking the official end of slavery in the United States.
