Here is a little video graph depicting the slave trade.
This is really worth watching; very interesting from a historical perspective.
Interesting that Portugal and Spain led the slave trade by far.
Where? :)
Interesting factoid. In media and the world, you’d get the impression the United States was largely responsible for slavery and the slave trade.
Yet <5% of slaves shipped across the Atlantic came to what is now the USA. The vast majority went to Brazil and the Caribbean.
But you never, ever hear about the original sin of Brazil or Barbados being slavery.
The US participation in the world slave trade was really the rump end of it. By far, the bulk of it was with Brazil and the Caribbean islands.
