Did Britain use the Royal Navy against the slave trade only from moral principle, or also for economic and strategic advantage?
Short answerMoral opposition mattered, but commercial and fiscal interests reinforced it, while anti-slavery enforcement also gave the Royal Navy legitimate opportunities to stop, search, and disrupt shipping.
NotesSeveral motives reinforced British abolition. Moral campaigners opposed slavery itself, businesses saw enslaved people as neither free customers nor a broad consumer market, and governments saw a population that paid no taxes while requiring coercion. Once suppression became policy, the Royal Navy's right to stop and search suspected slavers also created leverage over shipping routes and time-sensitive trade. The account treats moral opposition, strategic advantage, and commercial interests as overlapping motives. British enforcement also made a major impact on the slave trade across the Indian Ocean as well as the Atlantic.
