Its unusual name, coined by Thomas Carlyle in 1858, refers to an ear severed from Robert Jenkins, a captain of a British merchant ship . Despite stories to that effect, there is no evidence the severed ear was exhibited before the British Parliament . </P> <P> The seeds of conflict began with the separation of an ear from Jenkins following the boarding of his vessel by Spanish coast guards in 1731, eight years before the war began . Popular response to the incident was tepid until several years later when opposition politicians and the British South Sea Company hoped to spur outrage against Spain, believing that a victorious war would improve Britain's trading opportunities in the Caribbean . Also ostensibly providing the impetus to war against the Spanish Empire was a desire to pressure the Spanish not to renege on the lucrative asiento contract, which gave British slavers permission to sell slaves in Spanish America . </P>
