About Oman
Oman is an Arab country in southwest Asia on the southeast coast of the Arabian Peninsula. It borders the United Arab Emirates on the northwest, Saudi Arabia on the west and Yemen on the southwest. The coast is formed by the Arabian Sea on the south and east and the Gulf of Oman on the northeast. The country also contains Madha, an exclave enclosed by the United Arab Emirates, and Musandam, an exclave also separated by Emirati territory.
History
Oman before Islam
From the 6th century BC to the arrival of Islam in the 7th century AD, Oman was controlled and/or influenced by three Iranian dynasties, the Achaemenids, Parthians and Sassanids. Achaemenids in the 6th century BC controlled and influenced the Oman peninsula. This was most likely exerted from a coastal center such as Sohar. By about 250 B.C. the Parthian dynasty brought the Persian Gulf under their control and extended their influence as far as Oman. Because they needed to control the Persian Gulf trade route, the Parthians established garrisons in Oman. In the third century A.D. the Sasanids succeeded the Parthians and held the area until the rise of Islam four centuries later.

The arrival of Islam
On the advent of Islam, the faith reached Oman within Muhammad's lifetime. The conversion of Omanis is usually ascribed to Amr ibn al-As, who visited the region. By the middle of the eighth century AD, Omanis were practicing a unique sect of the faith, Ibadhism, which remains a majority sect only in Oman. Ibadhism has been characterized as "moderate conservatism," with tenets that are a mixture of both austerity and peace.

The Portuguese settlement
The Portuguese occupied Muscat for a 140-year period 1508–1648, arriving a decade after Vasco da Gama discovered the seaway to India. In need of an outpost to protect their sea lanes, the Europeans built up and fortified the city, where remnants of their colonial architectural style still remain. Revolting tribes drove out the Portuguese, but were pushed out themselves about a century later 1741 by the leader of a Yemeni tribe leading a massive army from various other tribes, who began the current line of ruling sultans. A brief Persian invasion a few years later was the final time Oman would be ruled by a foreign power. Oman has been self governing ever since.

Oman and East African Empire
In the 1690s Saif bin Sultan, the imam of Oman, pressed down the east African coast. A major obstacle was Fort Jesus, housing the garrison of a Portuguese settlement at Mombasa. After a two-year siege, it fell to Saif in 1698. Thereafter the Omanis easily ejected the Portuguese from Zanzibar and from all other coastal regions north of Mozambique. Zanzibar was a valuable property as the main slave market of the east African coast, and became an increasingly important part of the Omani empire, a fact reflected by the decision of the greatest 19th century sultan of Oman, Sa'id ibn Sultan, to make it from 1837 his main place of residence. Sa'id built impressive palaces and gardens in Zanzibar. He improved the island's economy by introducing cloves, sugar and indigo though at the same time he accepted a financial loss in cooperating with British attempts to end Zanzibar's slave trade. The link with Oman was broken after his death in 1856. Rivalry between his two sons was resolved, with the help of forceful British diplomacy, when one of them, Majid, succeeded to Zanzibar and to the many regions claimed by the family on the east African coast. The other, Thuwaini, inherited Muscat and Oman.
 

Politics
Chief of state and government is the hereditary sultān, Qaboos ibn Said Al Said who appoints a cabinet called the "Diwans" to assist him. In the early 1990s, the sultan instituted an elected advisory council, the Majlis ash-Shura, though few Omanis were eligible to vote. Universal suffrage for those over 21 was instituted on 4 October 2003. Over 190,000 people (74% of those registered) voted to elect the 84 seats. Two women were elected to seats. The country today has three women ministers Rawiyah bint Saud al Busaidiyah - Minister of Higher Education, Sharifa bint Khalfan al Yahya'eyah - Minister of Social Development and Rajiha bint Abdulamir bin Ali - Minister of Tourism. There are no legal political parties nor, at present, any active opposition movement. As more and more young Omanis return from education abroad, it seems likely that the traditional, tribal-based political system will have to be adjusted.A State Consultative Council, established in 1981, consisted of 55 appointed representatives of government, the private sector, and regional interests.

Geography
A vast gravel desert plain covers most of central Oman, with mountain ranges along the north (al Jebel al Akhdar) and southeast coast, where the country's main cities are also located: the capital city Muscat, Matrah and Sur in the north, and Salalah in the south. Oman's climate is hot and dry in the interior and humid along the coast. During past epochs Oman was covered by ocean. Fossilized shells exist in great numbers in areas of the desert away from the modern coastline. The peninsula of Musandam (Musandem), which has a strategic location on the Strait of Hormuz, is separated from the rest of Oman by the United Arab Emirates and is thus an exclave. The series of small towns known collectively as Dibba are the gateway to the Musandam peninsula on land and the fishing villages of Musandam by sea. Boats may be hired at Khasab for trips into the Musandam peninsula by sea. Oman has one other exclave, inside UAE territory, known as Madha. It is located halfway between the Musandam Peninsula and the rest of Oman.Belonging to Musandam governorate, it covers approximately 75 km² (29 sq mi). The boundary was settled in 1969. The north-east corner of Madha is closest to the Fujairah road, barely 10 m (32.8 ft) away. Within the exclave is a UAE enclave called Nahwa, belonging to the Emirate of Sharjah. It is about 8 km (5 mi) on a dirt track west of the town of New Madha. It consists of about forty houses with its own clinic and telephone exchange.
 

Oil and Gas
Commercial export of oil began in 1967 and since Sultan Qaboos' accession to the throne in 1970, many more oil fields have been found and developed. In June 1999, PDO discovered a new oil field in southern Oman after drilling and testing three wells which demonstrated the commercial viability of the reservoir. This is the most significant find in five years. Work is continuing on the RO 503.876 million ( US$1,300 million ) oil refinery project in Sohar, which was due to go into operation in 2006 with a 116,400 barrels a day refining capacity. In 2004, Oman Oil Refinery was supplied with about 78,200 barrels a day for refining, while PDO began using steam injection technology in several wells to increase their productivity. Oman's future economy is expected to depend on Sohar, which is growing very fast.

Since the slump in oil prices in 1998, Oman has made active plans to diversify its economy and is placing a greater emphasis on other areas of industry, such as tourism and natural gas. Oman's Basic Statute of the State expresses in Article 11 that, "The National Economy is based on justice and the principles of a free economy."
