Europeans travelled across the outward passage to sell things like firearms and rum to African tribes.
Slaves are Held in Slave Factories
Tribe leaders would buy these goods with slaves, many of which were either traitors, debtors or war criminals.
Slaves are Taken Across the Atlantic
Recently bought slaves were marched to the shore while wearing shackles. Africans from the inland have never seen white Europeans before and thought they were cannibals.
Goods Come Back from the New World
The slaves had their heads shaved and were branded with their owner's name and were held in these factories until they went onto on of the boats to the 'New World'.
While on the boats across the middle passage, slaves were kept in extremely cramped conditions and had to lie in their own waste.
The raw materials harvested by the slaves were things such as cotton, sugar, tobacco, coffee, and mahogany. These were then taken back to Europe to be manufactured and sold so that the cycle continues.
