President Joe Biden Thursday signed legislation making Juneteenth, a day commemorating the end of slavery in Confederate states, a federal holiday. "This will go down for me as one of the greatest honors I will have as president," Biden said. Juneteenth is a holiday commemorating the day news of the Emancipation Proclamation reached Texas, with block parties, cookouts and educational events. While Juneteenth celebrates the Emancipation Proclamation, which only freed slaves in the South, the 13th Amendment is what officially ended slavery in the U.S. Click the link in our bio to read more about the history of #Juneteenth. Correction: On the fifth photo of the gallery, the first paragraph should say “South Dakota.”
