I totally understand the American slave trade was awful. But I find it curious how it has so much more attention, as slavery was rampant all throughout history, examples such as Roman Slaves and huge amounts slavery of in a the middle east. Is there a reason behind it? Was African slavery more brutal or was it maybe because it was racial? Which is it was wouldn’t make sense either considering slavery in the middle east was also extremely racial through tribes and colour.
Reposting an earlier comment of mine:
It seems most historians (at least on this subreddit) consider the Transatlantic slave trade to be different from other forms of slavery, due to the ideology of racism and the negative effects it had on Africa. In this answer, which might be the closest to your question, u/sunagainstgold and others compare the Transatlantic and the Barbary slave trades. For comparisons with the Arab/Transsaharan slave trade, here u/Iguana_on_a_stick and others link to yet more earlier answers and discuss the question. And in this thread u/Zooasaurus explains how the Ottoman system of slavery worked.
