Dubai is the most populous city in the United Arab Emirates (UAE) and the capital of the Emirate of Dubai.
The history of human settlement in the area now defined by the United Arab Emirates is rich and complex, and points to extensive trading links between the civilisations of the Indus Valley and Mesopotamia, but also as far afield as the Levant. Archaeological finds in the emirate of Dubai, particularly at Al-Ashoosh, Al Sufouh and the notably rich trove from Saruq Al Hadid show settlement through the Ubaid and Hafit periods, the Umm Al Nar and Wadi Suq periods and the three Iron Ages in the UAE. The area was known to the Sumerians as Magan, and was a source for metallic goods, notably copper and bronze.
Dubai is situated on the Persian Gulf coast of the United Arab Emirates and is roughly at sea level (16 m or 52 ft above). The emirate of Dubai shares borders with Abu Dhabi in the south, Sharjah in the northeast, and the Sultanate of Oman in the southeast. Hatta, a minor exclave of the emirate, is surrounded on three sides by Oman and by the emirates of Ajman (in the west) and Ras Al Khaimah (in the north). The Persian Gulf borders the western coast of the emirate. Dubai is positioned atand covers an area of 1,588 sq mi (4,110 km2), which represents a significant expansion beyond its initial 1,500 sq mi (3,900 km2) designation due to land reclamation from the sea.
