In 1807, Parliament passed the Slave Trade Act of 1807, which outlawed the international slave trade, but not slavery itself. The legislation was timed to coincide with the expected prohibition from 1808 of international slave trading by the United States, Britain's chief rival in maritime commerce. This legislation imposed fines that did little to deter slave trade participants. Abolitionist Henry Brougham realised that trading had continued, and as a new MP successfully introduced the Slave Trade Felony Act 1811 which at last made the overseas slave trade a felony act throughout the empire. The Royal Navy established the West Africa Squadron to suppress the Atlantic slave trade by patrolling the coast of West Africa. It did suppress the slave trade, but did not stop it entirely. Between 1808 and 1860, the West Africa Squadron captured 1,600 slave ships and freed 150,000 Africans. They resettled many in Jamaica and the Bahamas. Britain also used its influence to coerce other countries to agree to treaties to end their slave trade and allow the Royal Navy to seize their slave ships.
