Gibraltar from the Spanish Province of CadizBud's Big Blue
Currency kerfuffles bedeviled 19th century Gibraltar. Actually, onward from 1704 when Anglo-Dutch forces captured Gibraltar from Spain, the coins of Spain and Britain circulated concurrently with Gibraltar’s. Exchange rate chaos ensued. In 1872, Spanish currency became the exclusive legal tender. Then, as a result of the Spanish-American War (1898), the Spanish peseta collapsed and the British pound replaced it.
The British have claimed the Rock of Gibraltar (1,400 feet) on the southern coast of Spain, about 2 square miles in area, since 1713. The promontory juts out at the entrance to the Mediterranean Sea. A very strategic location, this has been a key location for the British Royal Navy for many years.
As Bud says, Spain has not been happy with this reality, a legacy from when the British Empire ruled the seas.
