The Arabian Peninsula (əˈreɪbiən...; شِبْهُ الْجَزِيرَة الْعَرَبِيَّة, , "Arabian Peninsula" or جَزِيرَةُ الْعَرَب, , "Island of the Arabs"), or Arabia, is a peninsula in West Asia, situated northeast of Africa on the Arabian Plate. At , the Arabian Peninsula is the largest peninsula in the world.
Geographically, the Arabian Peninsula includes Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In the classical era the Sinai Peninsula was also considered a part of Arabia.
The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf and the Gulf of Oman to the northeast, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Ocean to the southeast. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of oil and natural gas.
Before the modern era, the region was divided into primarily four distinct regions: the Central Plateau (Najd and Al-Yamama), South Arabia (Yemen, Hadhramaut and Oman), Al-Bahrain (Eastern Arabia or Al-Hassa), and the Hejaz (Tihamah for the western coast), as described by Ibn al-Faqih.
Etymology of Arab
During the Hellenistic period, the area was known as Arabia or Aravia (Αραβία). The Romans named three regions with the prefix "Arabia", encompassing a larger area than the current term "Arabian Peninsula":
Arabia Petraea ("Stony Arabia"): for the area that is today southern modern Syria, Israel, Jordan, the Sinai Peninsula and northwestern Saudi Arabia. It was the only one that became a province, with Petra as its capital.
Arabia Deserta ("Desert Arabia"): signified the desert interior of the Arabian peninsula. As a name for the region, it remained popular into the 19th and 20th centuries, and was used in Charles M. Doughty's Travels in Arabia Deserta (1888).
