BDN– This Sunday marks the 156th anniversary of Juneteenth, a day that celebrates the liberation of the last Black men, women and children held in slavery in the United States.

On June 19, 1865, Union soldiers arrived in Galveston, Texas, where Black men and women finally learned slavery had been abolished — two years after President Abraham Lincoln signed the emancipation proclamation.

The following year, Texas saw the first official Juneteenth — also known as Emancipation Day or Juneteenth Independence Day — celebrations, and they soon spread to other states.

This year’s observance is the second year the holiday has been federally recognized, and the first year it is being observed by many state governments. Nonessential federal government offices and buildings will be closed to observe Juneteenth on Monday, June 20, including the United States Postal Service buildings. While many commercial businesses will remain open on Monday, Target and Best Buy will be closed in observance of the holiday.
