The Development of the Slave-Based Economy

• Stage 1: British ships left ports like London, Bristol, and Liverpool carrying manufactured goods such as firearms, textiles, and brass rods.
• Stage 2: In West Africa, these goods were traded for captive humans, who were then forced onto ships for the horrific Middle Passage to the Americas. Voyages took 6–12 weeks, with mortality rates frequently reaching 15–20%.
• Stage 3: The enslaved people were sold to plantation owners, and the ships returned to Britain packed with highly valuable sugar, tobacco, and rum.

Political Support and Deregulation

Before 1698, the English slave trade was strictly controlled by the Royal African Company (RAC), which held a royal monopoly granted by the monarchy.

• Following the Glorious Revolution, Parliament passed the Trade with Africa Act in 1698. This stripped the RAC of its monopoly, opening the brutal trade to independent Separate Traders who simply had to pay a 10% duty.
• Deregulation caused the trade to explode. The RAC's market share plummeted to just 1% by 1730, while private merchants transported tens of thousands of enslaved people annually.
• Political support further entrenched the system in 1713 via the Treaty of Utrecht. Britain secured the Asiento, a lucrative contract granting them the exclusive right to supply Spanish colonies with enslaved labor.

Formalising the Plantocracy

How did a customary labor practice become a rigid legal structure? The answer lies in the creation of a plantocracy, where a small elite controlled the land, tools, and laws.

• To protect their investments, elites passed strict laws like the 1705 Virginia Slave Codes. This formally established chattel enslavement, meaning humans were legally defined as personal property to be bought and sold.
• Crucially, unlike indentured servitude, chattel status was permanent and hereditary (passing from mother to child).
• To justify the brutal exploitation of human beings, elites actively constructed plantocracy racism, falsely claiming that Africans were biologically or intellectually inferior.

Early Opposition and Final Evaluation

Was this transition universally accepted without moral debate? No. Evidence shows that early religious groups provided significant pushback against the emerging system.

• In 1688, the Germantown Quaker Petition used the Golden Rule to argue that slavery was fundamentally unchristian.
• In 1700, the Puritan judge Samuel Sewall published an anti-slavery pamphlet denouncing the trade as man stealing, a biblical crime.
• Evaluating the Origins: Ultimately, the shift from temporary servants to a formalised slave economy was not an unavoidable accident; it was a calculated choice. The overwhelming economic demand for sugar, combined with explicit political deregulation (the 1698 Act), made the plantation system incredibly profitable. For the colonial elite, the economic benefits of permanent, hereditary labor simply outweighed the political risks of indentured servitude and the early moral objections of religious groups.
