from Wikipedia Dubai:
Dubai (in Arabic: دبيّ, transliteration: dubaīy) is one of the seven emirates of the United Arab Emirates (UAE), and is one of the country's main cities, sometimes called "Dubai City" to distinguish it from the emirate.
The modern emirate of Dubai was created consequent with the formation of the United Arab Emirates in 1971. However, written accounts documenting the existence of the city have existed 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.
A majority of the emirate's revenues are from trade, manufacturing and financial services. Revenues from petroleum and natural gas contribute less than 6% (2006) of Dubai's US$ 37 billion economy (2005). Dubai has attracted world-wide 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.
