Dubai, United Arab Emirates

In the early days since its inception, Dubai was constantly at odds with Abu Dhabi. In 1947, a border dispute between Dubai and Abu Dhabi on the northern sector of their mutual border, escalated into war. Arbitration by the British and the creation of a buffer frontier running south eastwards from the coast at Ras Hasian resulted in a temporary cessation of hostilities. Electricity, telephone services, and an airport were established in Dubai in the 1950s, when the British moved their local administrative offices there from Sharjah. After years of exploration following large finds in neighbouring Abu Dhabi, oil was eventually discovered in Dubai in 1971, albeit in far smaller quantities, after which the town granted concessions to international oil companies. The discovery of oil led to a massive influx of foreign workers, mainly Indians and Pakistanis. Between 1968 and 1975 the city's population grew by over 300%.
On 2 December 1971 Dubai, together with Abu Dhabi and five other emirates, formed the United Arab Emirates after the former protector, Britain, left the Persian Gulf in 1971. In 1973, Dubai joined the other emirates to adopt a uniform currency: the UAE dirham. In the 1970s, Dubai continued to grow from revenues generated from oil and trade, even as the city saw an influx of immigrants fleeing the Lebanese civil war. Border disputes between the emirates continued even after the formation of the UAE; it was only in 1979 that a formal compromise was reached that ended hostilities. The Jebel Ali port was established in 1979. Jafza (Jebel Ali Free Zone) was built around the port in 1985 to provide foreign companies unrestricted import of labour and export capital.
The Gulf War of 1990 had a huge effect on the city. Depositors withdrew massive amounts of money from Dubai banks due to uncertain political conditions in the region. Later in the 1990s many foreign trading communities—first from Kuwait, during the Gulf War, and later from Bahrain, during the Shia unrest—moved their businesses to Dubai. Dubai provided refuelling bases to allied forces at the Jebel Ali free zone during the Gulf War, and again during the 2003 Invasion of Iraq. Large increases in oil prices after the Gulf War encouraged Dubai to continue to focus on free trade and tourism.
