The Transatlantic Slave Trade was a trading pattern that most European Powers at the time followed to maximize profits from the exploits of the New World. These powers found that they could cultivate cash crops like sugar and mine for valuable minerals in South America and the Caribbean. These jobs were labor intensive and required a lot of people to do so. Natives weren’t reliable since they died easily of Europeans diseases. Europeans found an easy labor force and traded other goods with tribes for men who were taken on the Middle Passage and to such locations to work.
Originally humans simply hunted and gathered, but this nomadic lifestyle made having a large family difficult and culture was therefore rarely passed on.
