How about Juneteenth and old time slavery. Slavery didn’t end in the US on Juneteenth, only in Texas which was the last state in the Confederacy for emancipation to be enforced. Slavery existed in the five northern slave states for nearly six more months when the 13th Amendment was ratified. If you want to celebrate the end of slavery in the US it should be Decemberteenth, December 6.
Details. Meh!
