Admiral Sir John Hawkins was an English slave trader, naval commander and administrator, merchant, navigator, shipbuilder and privateer. His elder brother and trading partner was William. He was considered the first English trader to profit from the Triangle Trade, based on selling supplies to colonies ill-supplied by their home countries, and their demand for African slaves in the Spanish colonies of Santo Domingo and Venezuela in the late 16th century. He styled himself "Captain General" as the General of both his own flotilla of ships and those of the English Royal Navy and to distinguish himself from those Admirals that served only in the administrative sense and were not military in nature. His death and that of his second cousin and mentoree, Sir Francis Drake, heralded the decline of the Royal Navy for decades before its recovery and eventual dominance again helped by the propaganda of the Navy's glory days under his leadership.
