This Thursday, December 6, 2018, marks the third annual celebration of Abolition Day. Abolition Day was launched by the Humane Party in 2015 both (i) to commemorate the end of human slavery in the United States (1865) and (ii) to promote the abolition of all slavery. The date of December 6 was chosen for this national celebration because it was on this day in 1865 that the number of states necessary to ratify the 13th Amendment was reached.
