You didn’t make a thesis. You spouted a bunch of nonsense.

To answer your question, we simply don’t know. As I said, we don’t know all nations that ever existed or their laws. Many never had a written record.

You might be thinking of present day Haiti, which gained independence from France and abolished slavery in 1804. Haiti was Christian at the time by conquest so it’s far more accurate to say that Haiti abolished slavery in spite of Christianity rather than because of it since it was Christians who brought slavery to the island with colonization. Also, cites that reference Haiti are clear to point out that Haiti was the first Western country in the modern era. That’s a far cry from the first ever in all the world across all of time. See the difference?

Let’s also not forget that it was the Romans who brought slavery to the British Isles around 43 C.E. Christianity wasn’t the state religion then, but Rome didn’t withdraw from Britain until a half century or so after it was. So, 50 years or so of slavery and the Christians didn’t say boo. Even after Rome withdrew, Britains could enslave or be enslaved for centuries. Nobody got too fussed about it, especially all those stalwart, morally upright Christians showing everyone how to be good upstanding people, in-between burning people alive for heresy or witchcraft or being the wrong kind of Christian, of course.

Again, your entire article is beyond ludicrous. Wishful thinking. Fairly tales that didn’t get enough pixie dust to make them fly.

Read a history book. Google is your friend.
