Dubai is one of the seven emirates and most populous city of the United Arab Emirates (UAE). It is located along the southern coast of the Persian Gulf on the Arabian Peninsula. The city of Dubai is sometimes called "Dubai city" to distinguish it from the emirate.

Written accounts document the existence of the city for at least 150 years prior to the formation of the UAE. Dubai shares legal, political, military and economic functions with the other emirates within a federal framework, although each emirate has jurisdiction over some functions such as civic law enforcement and provision and upkeep of local facilities. Dubai has the largest population and is the second largest emirate by area, after Abu Dhabi. Dubai and Abu Dhabi are the only two emirates to possess veto power over critical matters of national importance in the country's legislature. Dubai has been ruled by the Al Maktoum dynasty since 1833. The emirates' current ruler, Mohammed bin Rashid Al Maktoum, is also the Prime Minister and Vice President of the UAE.

The emirate's revenues are from trade, real estate and financial services. Revenues from petroleum and natural gas contribute less than 6% (2006) of Dubai's US$ 37 billion economy (2005). Real estate and construction, on the other hand, contributed 22.6% to the economy in 2005, before the current large-scale construction boom. Dubai has attracted worldwide attention through innovative real estate projects and sports events. This increased attention, coinciding with its emergence as a world business hub, has also highlighted human rights issues concerning its largely foreign workforce.
