Oman (i/oʊˈmɑːn/oh-MAAN; Arabic: عمان ʻUmān), officially called the Sultanate of Oman (Arabic: سلطنة عُمان Salṭanat ʻUmān), is an Arab state in southwest Asia on the southeast coast of the Arabian Peninsula. It has a strategically important position at the mouth of the Persian Gulf. It is bordered by the United Arab Emirates (UAE) to the northwest, Saudi Arabia to the west, and Yemen to the southwest. The coast is formed by the Arabian Sea on the southeast and the Gulf of Oman on the northeast. The Madha and Musandam enclaves are surrounded by the UAE on their land borders, with the Strait of Hormuz and Gulf of Oman forming Musandam's coastal boundaries.
Muscat (Arabic: مسقط, Masqaṭ) is the capital of Oman. It is also the seat of government and largest city in the Governorate of Muscat. As of 2010 census, the population of the Muscat metropolitan area was 734,697. The metropolitan area spans approximately 1,500 km2 (580 sq mi) and includes six provinces called wilayats. Known since the early 1st century CE as an important trading port between the west and the east, Muscat was ruled by various indigenous tribes as well as foreign powers such as the Persians and the Portuguese Empire at various points in its history. 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, the Balochs and Gujaratis. Since the ascension of Qaboos bin Said as Sultan of Oman in 1970, Muscat has experienced rapid infrastructural development that has led to the growth of a vibrant economy and a multi-ethnic society.
