The last country to ban the Atlantic slave trade was Brazil in 1831. However, a vibrant illegal trade continued to ship large numbers of enslaved people to Brazil and also to Cuba until the 1860s, when British enforcement and further diplomacy finally ended the Atlantic trade.
So according to you, the Yankees ran the slave trade after 1860, but the slave trade didn’t exist after 1860.
Blathering idiot.
Brazil banned slavery in 1884. There are pictures of slave ships in the 1880's online. Google is your friend. Your imagination is not.
