Happy Juneteenth!
It took two and a half years after the Emancipation Proclamation before all of the slaves in the United States were finally freed. Several pockets resisted or hadn't been informed. The last group to be freed was in Galveston, Texas. On the morning of June 19, 1865, over 2,000 federal troops arrived there and Union Major General Gordon Granger and his men marched throughout the city, formally proclaiming the end of institutionalized slavery.
