 Goods from the slave trade were bought and sold on the Isle of Man, and Manx merchants, seamen, and ships were involved in the trade.No legislation was ever passed in England that legalised slavery, unlike the Portuguese "Ordenações Manuelinas" (1481–1514), the Dutch "East India Company Ordinances" (1622), and France's "Code Noir" (1685), and this caused confusion when Englishmen brought home slaves they had legally purchased in the colonies.John Locke, the philosophical champion of the Glorious Revolution, asserted that "every man has property in his own person" but allowed for the enslavement of war captives --a popular defense of slavery throughout the seventeenth, eighteenth, and nineteenth centuries in England (§27, Ch.V=; II.iv.24).
