Dubai, the city, and capital of the emirate of Dubai is one of the wealthiest of the seven emirates that constitute the federation of the United Arab Emirates, which was created in 1971 following independence from Great Britain. There are several theories about the origin of the name Dubai. One associates it with the data—a type of locust that infests the area—while another holds that it refers to a market that existed near the city. Dubai is a city of skyscrapers, ports, and beaches, where big business takes place alongside sun-seeking tourism. The new city center is a string of skyscrapers lining Sheikh Zayed Road. Notable among these are the Emirates Towers, which were built in the late 1990s and early 2000s and which house a hotel and government offices. Close to Sheikh Zayed Road is the Dubai International Financial Centre, housed in a futuristic arch-shaped building, and the Burj Khalifa, which at the time of its official opening in 2010 was the world’s tallest building; it was named after the president of the United Arab Emirates and emir of Abu Dhabi, Khalifa ibn Zayed Al Nahyan.
