Although stone tools have been found at many sites, little is known about UAE's early inhabitants as only a few settlements have been found. Many ancient towns in the area were trading centers between the Eastern and Western worlds. The remnants of an ancient mangrove swamp, dated at 7,000 BC, were discovered during the construction of sewer lines near Dubai Internet City. The area was covered with sand about 5,000 years ago as the coast retreated inland, becoming a part of the city's present coastline. Pre Islamic ceramics have been found from the 3rd and 4th century. Prior to Islam, the people in this region worshiped Bajir(or Bajar). The Byzantine and Sassanian (Persian) empires constituted the great powers of the period, with the Sassanians controlling much of the region. After the spread of Islam in the area, the Umayyad Caliph, of the eastern Islamic world, invaded south-east Arabia and drove out the Sassanians. Excavations by the Dubai Museum in the region of Al-Jumayra (Jumeirah) found several artifacts from the Umayyad period.
The earliest recorded mention of Dubai is in 1095, in the "Book of Geography" by the Andalusian-Arab geographer Abu Abdullah al-Bakri. The Venetian pearl merchant Gaspero Balbi visited the area in 1580 and mentioned Dubai (Dibei) for its pearling industry. Since 1799, there has been a settlement known as Dubai town. In the early 19th century, the Al Abu Falasa clan (House of Al-Falasi) of Bani Yasclan established Dubai, which remained a dependent of Abu Dhabi until 1833. On 8 January 1820, the sheikh of Dubai and other sheikhs in the region signed the "General Maritime Peace Treaty" with the British government. In 1833, following tribal feuding, the Al Maktoum dynasty (also descendants of the House of Al-Falasi) of the Bani Yas tribe left their ancestral home of the Liwa Oasis, South-west of the settlement of Abu Dhabi and quickly took over Dubai from the Abu Fasala clan without resistance.
