Charles revived the Family Compact with France on 15 August 1761 and joined in the Seven Years' War against Britain in 1762; the reformist policies he had espoused in Naples were pursued with similar energy in Spain, where he completely overhauled the cumbersome bureaucracy of the state. As a French ally he opposed Britain during the American Revolution in June 1779, supplying large quantities of weapons and munitions to the rebels and keeping one third of all the British forces in the Americas occupied defending Florida and what is now Alabama, which were ultimately recaptured by Spain. Charles died in 1788.
