Oman proper

Oman proper ( ) refers to a historical area within the present-day Sultanate of Oman. It lay inland from Muscat beyond the Jebel Akhdar (Green Mountains) and was centered on the city of Nizwa in the area of the current region of Ad Dakhiliyah. Along with Muscat and Dhofar, it was a constituent part of the Sultanate of Muscat and Oman, but with the 1970 palace coup, the term Oman alone was applied to the entire country.
