The War of Jenkins' Ear was a conflict between Great Britain and Spain that lasted from 1739 to 1748, with major operations largely ended by 1742. Its unusual name relates to Robert Jenkins, captain of a British merchant ship, who exhibited his severed ear in Parliament following the boarding of his vessel by Spanish coast guards in 1731. This affair and a number of similar incidents sparked a war against the Spanish Empire, ostensibly to encourage the Spanish not to renege on the lucrative asiento contract (permission to sell slaves in Spanish America).[5]
After 1742 the war merged into the larger War of the Austrian Succession involving most of the powers of Europe. Peace arrived with the Treaty of Aix-la-Chapelle in 1748. ROOS.
