Dubai is the most populous city in the United Arab Emirates (UAE) and the capital of the Emirate of Dubai, the most populated of the country's seven emirates.
Established in the 19th century as a small fishing village, Dubai grew into a regional trading hub from the early 20th century and grew rapidly in the late 20th and early 21st centuries with a focus on tourism and luxury. It is second-most in five-star hotels in the world and boasts the tallest building in the world, the Burj Khalifa, which is 828 metres (2,717 ft) tall.
In 1822, a British naval surveyor noted that Dubai was at that time populated with a thousand people living in an oval-shaped town surrounded by a mud wall, scattered with goats and camels. The main footpath out of the village led to a reedy creek while another trailed off into the desert which merged into caravan routes.
Dubai signed the General Maritime Treaty of 1820 with the British government along with other Trucial States, following the British campaign in 1819 against the Ras Al Khaimah. This led to the 1853 Perpetual Maritime Truce. Dubai also – like its neighbours on the Trucial Coast – entered into an exclusivity agreement in which the United Kingdom took responsibility for the emirate's security in 1892.
Dubai's geographical proximity to Iran made it an important trade location. The town of Dubai was an important port of call for foreign tradesmen, chiefly those from Iran, many of whom eventually settled in the town. By the beginning of the 20th century, it was an important port. At that time, Dubai consisted of the town of Dubai and the nearby village of Jumeirah, a collection of some 45 areesh (palm leaf) huts. By the 1920's, many Iranians settled in Dubai permanently, moving across the Persian Gulf. By then, amenities in the town grew and a modern quarter was established, Al Bastakiya.en.wikipedia.org
