However, Spain and Portugal are permitted a few years of continued slaving to replenish labor supplies.1817 Britain and Spain sign a treaty prohibiting the slave trade. British naval vessels are given right to search suspected slave ships. Still, loopholes in the treaty undercut its goals and the slave trade grows with the slave economies of Cuba and Brazil expanding rapidly.In the Le Louis case, British courts establish the principal that British naval vessels cannot search foreign vessels suspected of slaving unless permitted by their respective countries. The ruling hampers Britain’s efforts to suppress the trade.1819 The United States and Spain renew commercial agreements in the Adams-Onis Treaty.Congress passes legislation stiffening laws against American participation in the slave trade.Britain stations a naval squadron on the West African coast to patrol for illegal slave ships.1820 The United States deems slave trading an act of piracy and punishable by the death penalty.The U.S. Navy dispatches four vessels to patrol the coast of West Africa for slavers. This initial campaign lasts only four years before the Americans recall the cruisers and break off cooperation with the British.1824 Great Britain and the United States negotiate a treaty recognizing the slave trade as piracy and agree to work together to suppress it. But the U.S. Senate undercuts the treaty’s force in a series of amendments and Britain refuses to sign.1825 The Antelope, a slave ship sailing under the Venezuelan flag is seized in U.S. waters with a cargo of 281 Africans.

British cruisers are authorized to arrest suspected Spanish slavers and bring them before mixed commissions in Sierra Leone and Havana.1836 Portugal bans the slave trade.1837 Britain invites the United States and France to create an international patrol to stop slaving. The U.S. declines to participate.1838 In the British West Indies, most colonial assemblies have introduced legislation dismantling apprenticeships, which followed the emancipation of slaves. Laws against vagrancy and squatting attempt to keep the social and labor system of the plantation economy intact, with varying results.1839 Nicholas Trist, U.S. Consul in Havana, recommends that the administration dispatch a naval squadron to West Africa to patrol for slavers, warning that the British would police American vessels if the United States did not.The Amistad is seized off Long Island and taken to New London.J.M.W. Turner’s “The Slave Ship,” goes on display in London. The piece was inspired by a recent incident in which a captain threw slaves overboard during an epidemic. As insurance companies only covered slaves drowned at sea, profit-minded captains often cast the sick or dying into the ocean.1841 Nicholas Trist is dismissed as U.S. Consul in Havana amid allegations he connived to sell U.S. vessels to Spanish slave traders or at least failed to stop the illegal transactions.1860s The Atlantic slave trade was abolished over a 30-year period ending with Portugal’s 1836 ban on slave trading. But legal abolition did not end the still profitable trade. It continued illegally well into the 19th century. As long as there remained a market for slaves in the Americas, mostly in Brazil and Cuba, the trade would continue until the 1860s.
