By the 1770s, Liverpool had become Britain’s leading slave-trading port and one of the fastest-growing cities in the empire. Ships left its docks carrying manufactured goods to West Africa, where merchants exchanged them for enslaved Africans. Captives were then transported across the Atlantic in brutal conditions before ships returned with plantation goods such as sugar, tobacco, cotton, and rum. The wealth generated by this trade transformed Liverpool’s docks, banks, warehouses, and merchant houses.
In The Wealth of Nations, Adam Smith criticised monopolies and colonial trade restrictions, arguing that powerful merchants often shaped imperial policy for their own profit rather than the good of society. He believed freer trade could make nations wealthier, but he also warned that merchants frequently sought special privileges and influence over government. Liverpool reflected this contradiction. Many small traders and manufacturers who wanted access to these booming imperial markets demanded “free trade” and opposed old monopolies such as the Royal African Company, yet the prosperity of the port still depended heavily on slavery and imperial expansion.
