ABU DHABI CONFIRMED AS HOST CITY FOR GAMES OF THE FUTURE 2025 May 28, 2025, 11:07 PM ET (Globe and Mail)

Abu Dhabi, city and capital of Abu Dhabi emirate, one of the United Arab Emirates (formerly Trucial States, or Trucial Oman), and the national capital of that federation. The city occupies most of a small triangular island of the same name, just off the Persian Gulf coast and connected to the mainland by a short bridge. Abu Dhabi was formerly an undeveloped town of only local importance, but the emirate’s oil revenues enabled it to evolve into a modern city with a fully developed infrastructure.

No settlement existed at Abu Dhabi town before 1761, when tribesmen of the Āl Bū Falāh clan of the Banū Yās confederation, rulers of Abu Dhabi then as now, settled there. They moved their headquarters to this coastal islet from the inland Līwā (Al-Jiwāʾ) oasis in 1795. Through most of the 19th and early 20th centuries, the town, though capital of one of the chief sheikhdoms of the Trucial Coast, yielded pride of place in trade and economic importance to the towns of Dubai and Sharjah, capitals of neighbouring Trucial sheikhdoms. At the beginning of the 20th century, Abu Dhabi town’s population was estimated at 6,000, and pearl diving from the rich offshore banks and some local trade (chiefly in the hands of Iranians and Indians) sustained the economy. Pearling declined with the development of the Japanese cultured-pearl industry and the worldwide economic depression beginning in 1929.

The discovery (1958) and commercial production (since 1962) of the rich oil fields of Abu Dhabi emirate revolutionized the political and economic position of the town. Great Britain, as the protecting power of the then Trucial States, established a separate Political Agency at Abu Dhabi in 1961, removing the sheikhdom from dependence on the political agent at Dubai. As capital of the chief oil-producing state in the region, Abu Dhabi town had large sums available for urban development. The town modernized slowly, however, because of the extremely conservative policies of Sheikh Shakhbout ibn Sultan Al Nahyan (reigned 1928–66). In 1966 he was deposed in favour of his younger brother Zayed ibn Sultan, former governor of the Abu Dhabi-controlled portion of Al-Buraimi oasis. Sheikh Zayed began developing a road network radiating from Abu Dhabi town and had a seawall built along the northern end of the island containing the town. Under an ambitious five-year development plan, inaugurated in 1968, the town was thoroughly modernized. Electricity, running water, and a central sewerage system were installed, and modern government buildings, hotels, housing projects, and a new port extension were built. An oil refinery on nearby Umm al-Nār Island began production in 1976. Abu Dhabi’s international airport is at the south end of the island. Light industry is concentrated at nearby Muṣaffaḥ. Motor roads link the cities of Abu Dhabi with Dubai (northeast), Al-Ain oasis (east), and Qatar (west).

When Britain finally left the Persian Gulf and when the United Arab Emirates achieved political independence (December 1971), a compromise decision made Abu Dhabi the provisional national capital. It was made the permanent capital of the United Arab Emirates in the early 1990s. Since that time, a number of projects have been initiated to expand the city as a centre for tourism and commerce. Development plans in Abu Dhabi rapidly led to the construction of a variety of landmark hotels, the establishment of an international airline, Etihad (Al-Ittiḥād) Airways, to serve the capital, and the development of a range of commercial and residential properties. Pop. (2015 est.) 1,202,756.

United Arab Emirates, federation of seven emirates along the eastern coast of the Arabian Peninsula. Abu Dhabi, its largest emirate, is known for its oil wealth, and the emirate of Dubai serves as an international hub for business, finance, and travel. The country’s immense wealth (the sovereign wealth fund of Abu Dhabi alone amounted to more than $1.4 million per Emirati in 2024) has fueled a rapid development of infrastructure, luxury tourism, and advanced technological innovation.

Abu Dhabi (Abū Ẓaby), which comprises more than three-fourths of the federation’s total land area, is the center of the United Arab Emirates’s oil industry and borders Saudi Arabia on the federation’s southern and eastern borders. The port city of Dubai, located at the base of the mountainous Musandam Peninsula, is the capital of the emirate of Dubai (Dubayy) and is one of the region’s most vital commercial and financial centers, housing hundreds of multinational corporations in a forest of skyscrapers. The smaller emirates of Sharjah (Al-Shāriqah), Ajman (ʿAjmān), Umm al-Quwain (Umm al-Qaywayn), and Ras al-Khaimah (Raʾs al-Khaymah) also occupy the peninsula, whose protrusion north toward Iran forms the Strait of Hormuz, which links the Persian Gulf to the Gulf of Oman. The federation’s seventh member, Fujairah (Al-Fujayrah), faces the Gulf of Oman and is the only member of the union with no frontage along the Persian Gulf.

Historically the domain of individual Arab clans and families, the region now comprising the emirates also has been influenced by Persian culture owing to its close proximity to Iran, and its porous maritime borders have for centuries invited migrants and traders from elsewhere. In the 18th century, Portugal and the Netherlands extended their holdings in the region but retreated with the growth of British naval power there; following a series of truces with Britain in the 19th century, the emirates united to form the Trucial States (also called Trucial Oman or the Trucial Sheikhdoms). The states gained autonomy following World War II (1939–45), when the trucial states of Bahrain and Qatar declared independent statehood. The rest were formally united in 1971, with the city of Abu Dhabi serving as the capital. The stability of the federation has since been tested by rivalries between the families governing the larger states of Abu Dhabi and Dubai, though external events such as the Persian Gulf War (1990–91) and an ongoing territorial dispute with Iran have served to strengthen the emirates’ political cohesion.

The emirates comprise a mixed environment of rocky desert, coastal plains and wetlands, and waterless mountains. The seashore is a haven for migratory waterfowl and draws birdwatchers from all over the world; the country’s unspoiled beaches and opulent resorts also have drawn international travelers. Standing at a historic and geographic crossroads and made up of diverse nationalities and ethnic groups, the United Arab Emirates present a striking blend of ancient customs and modern technology, of cosmopolitanism and insularity, and of wealth and want. The rapid pace of modernization of the emirates prompted travel writer Jonathan Raban to note of the capital: “The condition of Abu Dhabi was so evidently mint that it would not have been surprising to see adhering to the buildings bits of straw and polystyrene from the crates in which they had been packed.”
