Oman, officially the Sultanate of Oman, is an Arab country on the southeastern coast of the Arabian Peninsula in the Middle East. Holding a strategically important position at the mouth of the Persian Gulf, the country shares land borders with the United Arab Emirates to the northwest, Saudi Arabia to the west, and Yemen to the southwest, and shares marine 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 UAE on their land borders, with the Strait of Hormuz (which it shares with Iran) and Gulf of Oman forming Musandam's coastal boundaries.
Oman is an absolute monarchy. The Sultan Qaboos bin Said al Said has been the hereditary leader of the country since 1970. Sultan Qaboos is the longest-serving current ruler in the Middle East, and third-longest current reigning monarch in the world.
