Hello!
From 1776, after the Declaration of the independence of the United States, there was a constant abolitionist process between the northern states.
This situation contrasted with the experience of the southern states, whose economic activities required slave labor. Due to the prohibition of importing slaves from abroad, their trade continued clandestinely. Moreover, the southern aristrocacia developed an ideological discourse, with which it justified slavery.
In 1865, slave labor was finally abolished after the Union's victory in the American Civil War.
