A Brief History of Oman

Oman adopted Islam in the seventh century A.D., during the lifetime of the Prophet Muhammad. Ibadhism, a form of Islam distinct from Shiaism and the "Orthodox" schools of Sunnism, became the dominant religious sect in Oman by the eighth century A.D. Oman is the only country in the Islamic world with a majority Ibadhi population. Ibadhism is known for its "moderate conservatism." One distinguishing feature of Ibadhism is the choice of ruler by communal consensus and consent.

Contact with Europe was established in 1508 when the Portuguese conquered parts of Oman's coastal region. Portugal's influence predominated for more than a century. Fortifications built during the Portuguese occupation can still be seen at Muscat.

Except for a period when Persia conquered parts of Oman, Oman has been an independent nation. After the Portuguese were expelled in 1650 and while resisting Persian attempts to establish hegemony, the Sultan of Oman extended his conquests to Zanzibar, other parts of the eastern coast of Africa, and portions of the southern Arabian Peninsula. During this period, political leadership shifted from the Ibadhi imams, who were elected religious leaders, to hereditary sultans who established their capital in Muscat. The Muscat rulers established trading posts on the Persian coast and also exercised a measure of control over the Makran coast (now Pakistan). By the early 19th century, Oman was the most powerful state in Arabia and had a major presence on the East African coast.
