Oman
Oman, officially the Sultanate of Oman, is a country in Western Asia. It is situated on the southeastern coast of the Arabian Peninsula, and spans the mouth of the Persian Gulf. Oman shares land borders with Saudi Arabia, United Arab Emirates, and Yemen; while sharing maritime borders with Iran and Pakistan. The coast is formed by the Arabian Sea on the southeast, and the Gulf of Oman on the northeast. The Madha and Musandam exclaves are surrounded by the United Arab Emirates on their land borders, with the Strait of Hormuz and the Gulf of Oman forming Musandam's coastal boundaries. Muscat is the nation's capital and largest city. From the 17th century, the Omani Sultanate was an empire, vying with the Portuguese and British empires for influence in the Persian Gulf and Indian Ocean. At its peak in the 19th century, Omani influence or control extended across the Strait of Hormuz to modern-day Iran, and Pakistan, and as far south as Zanzibar.
