The Anglo-Spanish War of 1727–1729 was a limited war that took place between Great Britain and Spain during the late 1720s, and consisted of a failed Spanish attempt to capture Gibraltar and an unsuccessful British Blockade of Porto Bello. It eventually ended with a return to the previous status quo ante bellum following the Treaty of Seville.

The Kingdom of Spain entered a new era with the death of Charles II, the last Spanish Habsburg monarch, who died childless in 1700. The War of the Spanish Succession was fought between proponents of a Bourbon prince, Philip of Anjou, and the Austrian Habsburg claimant, Archduke Charles. After the wars were ended with the Peace of Utrecht, Philip V's rule began in 1715, although he had to renounce his place in the succession of the French throne.
