It does if you look at the numbers. Prior to Europeans deciding they were going to colonise two entire continents with African slaves, the slave trade within and out of Africa went along historic routes over the Sahara into North Africa and from there to the Middle East and Southern Europe. This was at a rate of around a 10,000 people per year taken from all Africa.
This slave trade continued during the Trans-Atlantic slave trade which was an additional 10,000 people per year by 1670 (20k total), then an additional 20,000 (30k total) people per year by 1700, then an additional 50,000 (60k total) people per year by 1750 until abolition by Britain in 1807 after which it gradually tapers off.
The population was 20-25 million people in that region of Africa right before the Transatlantic slave trade. Afterwards, most of central Africa was depopulated.
To try and help you visualise the impact, we can apply this to London. There are currently 10.5 million people in London. About half of the ones that were in Africa.
Now imagine London having to catch and sell as slaves half of the above.
For thirty years, catch and sell 10,000 Londoners every year
For fifty years, catch and sell 15,000 Londoners every year
For fifty seven years, catch and sell 30,000 Londoners every year
If you cannot see how such demand would cause London to descend into savage enslave or be enslaved warfare in a ruined landscape of devastation, then I’m not sure any explanation could. And this isn’t even counting all the lives lost in these wars from being outright killed.
