During the War of Spanish Succession, Spain lost Gibraltar to an Anglo-Dutch fleet and when the war finished in 1714, Spain was forced to accept the loss of Gibraltar in Treaty of Utrecht. Despite this it was a long term goal of Spain to recover both Gibraltar and the island of Minorca from the British. After the Treaty of Vienna in 1725, Spain had the support of Austria, and thought the time was right to try to recapture Gibraltar. As a reaction Britain signed the Treaty of Hanover with France and Prussia.
