Petra, originally known to its inhabitants as 'Raqmu', is a historical and archaeological city in southern Jordan. Petra lies on the slope of Jabal Al-Madbah in a basin among the mountains which form the eastern flank of the Arabah valley that runs from the Dead Sea to the Gulf of Aqaba. Petra is believed to have been settled as early as 9,000 BC, and it was possibly established in the 4th century BC as the capital city of the Nabataean Kingdom. The Nabataeans were nomadic Arabs who invested in Petra's proximity to the trade routes by establishing it as a major regional trading hub.

The trading business gained the Nabataeans considerable revenue and Petra became the focus of their wealth. The earliest historical reference to Petra was an attack to the city ordered by Antigonus I in 312 BC recorded by various Greek historians. The Nabataeans were, unlike their enemies, accustomed to living in the barren deserts, and were able to repel attacks by utilizing the area's mountainous terrain. They were particularly skillful in harvesting rainwater, agriculture and stone carving. Petra flourished in the 1st century AD when its famous Khazneh structure – believed to be the mausoleumof Nabataean King Aretas IV – was constructed, and its population peaked at an estimated 20,000 inhabitants.

A regional military power in the 18th century, Muscat's influence extended as far as East Africa and Zanzibar. As an important port-town in the Gulf of Oman, Muscat attracted foreign tradesmen and settlers such as the Persians and the Balochis.

Dubai  is the largest and most populous cityin the United Arab Emirates (UAE). On the southeast coast of the Persian Gulf, it is the capital of the Emirate of Dubai, one of the seven emirates that make up the country.
