United Arab Emirates a federation of Seven Emirates

The United Arab Emirates is comprised of seven emirates, which occupy the southeastern corner of the Arabian Peninsula.
ABU DHABI
Abu Dhabi, by far the largest emirate, is ruled by the Al Nahyan family. It occupies 67,340 square kilometres or 86.7% of the total area of the country. The emirate is primarily a vast desert area with about two dozen islands in the coastal waters, including the island where the city of Abu Dhabi is located, plus six sizeable islands further out in the Arabian Gulf. The population of the emirate is concentrated in three areas: the capital city, Abu Dhabi; Al Ain, an oasis city located near the Hajar Mountains; and the villages of the Liwa oases.
DUBAI
Dubai, the second largest of the seven emirates, is ruled by the Al Maktoum family. It occupies an area of approximately 3,900 kilometres, which includes a small enclave called Hatta, situated close to Oman, amongst the Hajar Mountains. Dubai, the capital city, is located along the creek, a natural harbour, which traditionally provided the basis of the trading industry. Pearling and fishing were the main sources of income for the people of Dubai. Under the wise leadership of its rulers, Dubai’s focus on trade and industry transformed it into the leading trading port along the southern Gulf. His Highness Sheikh Mohammed bin Rashid Al Maktoum is the current ruler of Dubai.
SHARJAH
Sharjah, which shares its southern border with Dubai, is ruled by the Al Qasimi family. It is approximately 2,600 square kilometres and is the only emirate to have coastlines on both the Arabian Gulf and the Gulf of Oman. In the nineteenth century the town of Sharjah was the leading port in the lower Gulf. Produce from the interior of Oman, India and Persia arrived there. Sharjah’s salt mines meant that salt constituted an important part of its export business, along with pearls.
AJMAN
Ajman is the smallest emirate, comprising only 260 square kilometres. It is ruled by the Al Nuami family. Surrounded mostly by the emirate of Sharjah, Ajman also possesses the small enclaves of Manama and Musfut in the Hajar Mountains. Along the creek dhow building was the specialised trade. Fishing and date-trees provided the local population with their primary means of sustenance.
UMM AL QAIWAIN
Umm Al Qaiwain is ruled by the Al Mualla family. It is the second smallest emirate, with a total area of around 770 square kilometres. Positioned between the emirates of Sharjah and Ajman to the south and Ras Al Khaimah to the north, Umm Al Qaiwain has the smallest population.
RAS AL KHAIMAH
Ras Al Khaimah, the most northerly emirate, is ruled by another branch of the Al Qasimi family. It covers an area of 1,700 square kilometres. Thanks to the run-off water from the Hajar Mountains, Ras Al Khaimah has a unique abundance of flora, so it is no surprise that agriculture is important to the local economy. The emirate also benefits from its stone quarries, and fishing, which is plentiful in the rich waters of the Gulf.
FUJAIRAH
The only emirate without a coastline on the Arabian Gulf is Fujairah, which is ruled by the Al Sharqi family. Situated along the coast of the Gulf of Oman, Fujairah covers about 1,300 square kilometres. Unlike other emirates, where the desert forms a large part of the terrain, mountains and plains are its predominant features. Fujairah’s economy is based on fishing and agriculture. Like Ras Al Khaimah, the land in Fujairah is irrigated by rainwater from the Hajar Mountains, making it ideal for farming.
