Dubai, constituent emirate of the United Arab Emirates (formerly Trucial States or Trucial Oman). The second most populous and second largest state of the federation (area 1,510 square miles [3,900 square km]), it is roughly rectangular, with a frontage of about 45 miles (72 km) on the Persian Gulf. The emirate’s capital, also named Dubai, is the largest city of the federation. The city is located on a small creek in the northeast part of the state. More than nine-tenths of the emirate’s population lives in the capital and nearby built-up sections. Dubai is surrounded by Abu Dhabi emirate on the south and west and by Al-Shāriqah emirate on the east and northeast. In addition, the small exclave (detached section) of Al-Ḥajarayn in the Wadi Ḥattá, more than 25 miles (40 km) from the nearest territory of Dubai proper, belongs to the state.
