ThePersian Gulf is home to manyislands, mostly small, distributed in the gulf's entire geographic area and administered by the neighboring nations. Most islands are sparsely populated, with some being barren, and some utilized for communication, military, or as shipdocks. Some of the islands in the Persian Gulf areartificially constructed islands. The artificial islands often serve as tourist resorts, housing developments, or hotels. Despite their small sizes, some of these artificial islands have caused serious hazards for the already fragile ecosystem of the Gulf and its dwindling wildlife mass. A few of the Gulf islands are also historically significant, having been utilized by the ancient empires, neighboring kingdoms, and in the recent times, colonial powers such as theBritish Empire, and thePortuguese Empire. Recent globalization, and discovery of oil, has made some of the Persian Gulf islands very significant for developed nations as a source of oil and raw industrial material. Recent wars, and political unrest has also made these islands strategic military locations for foreign powers fromAmerica andEurope.
Some islands in thePersian Gulf are nations themselves;Bahrain, an independentGulf state, is the only gulf country that is also an island.
