The Transatlantic Slave Trade consisted of three journeys, known as the Triangle of Trade: The outward passage from Europe to Africa, carrying manufactured goods. The middle passage from Africa to the Americas or the Caribbean, carrying African captive slaves and other 'commodities’. The homeward passage carrying sugar, tobacco, rum, rice, cotton and other goods back to Europe.

In ancient Egypt, the exchange of goods without the use of money is known as "barter." This system allowed individuals to trade items directly based on mutual needs and values.
