Dubai (Arabic: دبيّ‎ Dubeii; IPA: [du'beii]; English pronunciation: /duːˈbaɪ/ doo-BY) is an emirate within the United Arab Emirates (UAE). A city within the emirate is also named Dubai. The emirate is located south of the Persian Gulf on the Arabian Peninsula and has the largest population with the second-largest land territory by area of all the emirates, after Abu Dhabi. Dubai and Abu Dhabi are the only two emirates to have veto power over critical matters of national importance in the country's legislature. Dubai City is located on the emirate's northern coastline.

The earliest mention of Dubai is in 1095, and the earliest settlement known as Dubai town dates from 1799. Dubai was formally established in 1833 by Sheikh Maktoum bin Buti al Maktoum when he persuaded 800 members of the Bani Yas tribe, living in what is now part of Saudi Arabia, to follow him to the Dubai Creek by the Al Abu Falasa clan of Bani Yas. It remained under clan control when the United Kingdom assumed the protection of Dubai in 1892. Its geographical location made it an important trading hub and by the beginning of the 20th century, it was an important port.

The United Arab Emirates (UAE), sometimes simply called the Emirates, is a country situated in the southeast of the Arabian Peninsula in Western Asia on the Persian Gulf, bordering Oman to the east and Saudi Arabia to the south, as well as sharing sea borders with Qatar to the west and Iran to the north.

The UAE is a federation of seven emirates (equivalent to principalities), each governed by a hereditary emir, with a single national president. The constituent emirates are Abu Dhabi, Ajman, Dubai, Fujairah, Ras al-Khaimah, Sharjah, and Umm al-Quwain. The capital is Abu Dhabi, which is also the state's center of political, industrial, and cultural activities.

Prior to independence in 1971, the UAE was known as the Trucial States or Trucial Oman, in reference to a 19th-century truce between the local sheikhs, hereditary rulers of the territories, and the United Kingdom. The term Pirate Coast was also used by some to refer to the emirates from the 18th to the early 20th century, owing to the preponderance of pirates operating from Emirati ports.
