Juneteenth day, a June 19 holiday, celebrates and symbolizes the end of slavery in the United States. President Abraham Lincoln issued the Emancipation Proclamation on September 22, 1862. It was not until June 19, 1865 that all slaves were finally freed. That concluding event was when General Gordon Granger rode into Galveston, Texas with his troops and issued Order Number 3 which finally freed the last of the slaves.
The formal end of slavery was marked by the passing of the 13th amendment of the constitution.
In 2021, Juneteenth became a Federal holiday. The formal name is Juneteenth National Independence Day. It is sometimes referred to as Emancipation Day or Freedom Day.
