Gibraltar is a British Overseas Territory. It was ceded to Britain under the Terms of the Treaty of Utrecht in 1713 at the end of the war of Spanish succession. Under this treaty Spain lost most of her European empire.

They never did. --- The British Empire does not exist. It collapsed in the 1930's and the members of the former British Empire were invited to join the British Commonwealth which exists to this day. Gibraltar has chosen to remain under British Sovereignty against the wishes of the Spanish who see this as belonging to Spain. In turn, Britain has promised to protect former colonies who wish to remain under British Rule such as the Falklands, Gibraltar and many other small nation states.
Great Britain and France having agreed a truce, the pace of negotiation now quickened, and the main treaties were finally signed on 11 April 1713.
I believe that Gibraltar is the only territory to have remained a British possession since 1713. The Spanish garrison at Gibraltar was captured by the British in 1704 and ceded to Britain under the terms of the Treaty of Utrecht in 1713. However, whether it should be regarded as a country is debatable because it would simply be reabsorbed into the rest of Spain if the British were to withdraw. Spanish attempts to regain the region by force were unsuccessful and since 1783 have pressed for a peaceful and negotiated return of "The Rock". This has been rejected by every British government as Gibraltar's strategic value at the entrance to the Mediterranean continued to grow. In the 1960's a referendum of the population produced a majority in favour of remaining a British Territory. The reaction from Spain was to close the border which remained closed until 1985. More recently there have been Anglo-Spanish talks on a proposed joint sovereignty of the territory but this was subsequently rejected in another referendum by 98.5% of Gibraltar's population!
