times only for the southern region. Because its use became limited to the south, the whole peninsula was simply called Arabia. Arabia Deserta was the entire desert region extending north from Arabia Felix to Palmyra and the Euphrates, including all the area between Pelusium on the Nile and Babylon. This area was also called Arabia and not sharply distinguished from the peninsula. The Arabs and the Ottoman Empire considered the west of the Arabian Peninsula region where the Arabs lived 'the land of the Arabs' – Bilad al-'Arab (Arabia), and its major divisions were the bilad al-Sham (Levant), bilad al-Yaman (Yemen), and Bilad al-'Iraq (Iraq). The Ottomans used the term Arabistan in a broad sense for the region starting from Cilicia, where the Euphrates river makes its descent into Syria, through Palestine, and on through the remainder of the Sinai and Arabian peninsulas. The provinces of Arabia were: Al Tih, the Sinai peninsula, Hedjaz, Asir, Yemen, Hadramaut, Mahra and Shilu, Oman, Hasa, Bahrain, Dahna, Nufud, the Hammad, which included the deserts of Syria, Mesopotamia and Babylonia. Geography The Arabian Peninsula is located in the continent of Asia and is bounded by (clockwise) the Persian Gulf on the northeast, the Strait of Hormuz and the Gulf of Oman on the east, the Arabian Sea on the southeast, the Gulf of Aden, Guardafui Channel and Somali Sea on the south, the Bab-el-Mandeb strait on the southwest and the Red Sea, which is located on the southwest and west. The northern portion of the peninsula merges with the Syrian Desert with no clear borderline, although the northern boundary of the peninsula is generally considered to be the northern borders of Saudi Arabia and Kuwait, also southern regions of Iraq and Jordan. The most prominent feature of the peninsula is desert, but in the southwest, there are mountain ranges, which receive greater rainfall than the rest of the peninsula. Harrat ash Shaam is a large volcanic field that extends from northwestern Arabia into Jordan and southern Syria. Political boundaries The Peninsula's constituent countries are (clockwise from north to south) Kuwait, Qatar, and the United Arab Emirates (UAE) on the east, Oman on the southeast, Yemen on the south, and Saudi Arabia at the center. The island country of Bahrain lies just off the east coast of the Peninsula. Due to Yemen's jurisdiction over the Socotra Archipelago, the Peninsula's geopolitical outline faces the Guardafui Channel
