> You mean, we ended it in the United States. Other countries ended slavery before we did.

Sort of? The major European powers "ended" it at home by outsourcing it to their colonies. It's not like Britain, France, Belgium, etc. weren't still practicing explicit chattel slavery well into the 20th century.

And others ended it much later. Saudi Arabia abolished slavery in 1962 (but in practice it still continued after that).

For some context on this as it pertains to the New World check out Bartolomé de las Casas.

And it's still a global problem today, with many still enslaved around the world

Here we're talking about the chattel slavery of Africans as a labor force, not the general concept of slavery.
