Americans have been celebrating Juneteenth this weekend, the third year since the holiday was given federal status by President Biden in 2021.

The date commemorates the fall of slavery in Galveston, Texas, two years after the Emancipation Proclamation was issued in 1863 to free enslaved Black people held in the Confederacy.

News of Union troops' victory over the Confederates spread slowly across the South, eventually reaching the shores of Galveston in 1865.
