Abu Dhabi is the capital of the United Arab Emirates. Abu Dhabi sits on a T-shaped island jutting out into the Persian Gulf from the central west coast. In 2014, the city proper had a population of 1.5 million people.
The city was founded in 1791 by the Bedouin tribe of the Banu Yas, who had occupied the region, leaving Najd because they were at odds with the Wahhabis of Arabia.
Abu Dhabi houses federal government offices, is the seat of the UAE government, seat of the family of the Emirs of Abu Dhabi and the President of the UAE, who hails from this family. Its rapid development and urbanization, coupled with the relatively high average income of its population, has transformed the city into a large and advanced metropolis. Today the city is the country's center in political and industrial activities, as well as being an important cultural and commercial centre. Abu Dhabi accounts for about two-thirds of the UAE economy with approximately US$400 billion.
Abu Dhabi is the fourth most expensive city for expatriate workers in the region. Outscoring more than 300 cities, including Tokyo, Basel, Munich and Vienna, the UAE capital has returned to the top of the list as the safest city in the world. The emirate's security index rose from 86.46 points in the first half of 2017 to 88.26 points in the first six months of 2018.
