Bounded on the east by the Persian Gulf...
Bounded on the east by the Persian Gulf, on the south by the Arabian Sea, and on the west by the Red Sea, it is bounded on the north by the great “sand sea” of the Syrian desert. In outline, Arabia is a quadrilateral with an area of 1.2 million square miles. The Red Sea littoral from the Gulf of Aqaba in the north to the Bab-el-Mendeb in the south, is 1200 miles long; and the distance from Bab-el-Mendeb in the west to Ras-el-Hadd in the east is roughly the same.
In configuration, Arabia is a vast plateau rising gently from east to west. Except for Yemen and the valleys interspersed in the western mountain ranges, the whole country is sandy or rocky, and dry and barren.
Following are the political divisions of the Arabian peninsula (1992): The Kingdom of Saudi Arabia The Republic of Yemen The Sultanate of Oman The United Arab Emirates The State of Qatar The State of Bahrain The State of Kuwait Following is a brief description of each of these seven political units: 1.The Kingdom of Saudi Arabia The Kingdom of Saudi Arabia accounts for 850,000 square miles of the Arabian peninsula. Its population is estimated at ten million, and its capital is Riyadh.
The “maritime” provinces of the Kingdom are Hijaz and Aseer on the Red Sea. The narrow coastal plain of Tihama runs parallel to the Red Sea. The twin cities of Makkah and Medina are in the province of Hijaz. Hijaz, therefore, is the holy land of Islam. The population of Hijaz is estimated at two million, and its area is 135,000 square miles.
Other cities and towns in Hijaz are Jeddah, the port of Makkah, and the country's major commercial center; Yenbo, the port of Medina; Ta'if, a hill station in the south-east of Makkah, and the summer capital of the kingdom; Khyber, Tabuk and Tayma. The “Great Design” of Islam was perfected in Hijaz, and the history of its birth and growth is inextricably bound up with this province which makes it the hub of the Muslim world.
Aseer is the relatively fertile strip of coastal plains and mountains in the south-west, north of Yemen, with some peaks rising as high as 10,000 feet, and sufficient rainfall to permit terraced farming. The famous hill station of Abha and the important agricultural settlement of Jizan are in Aseer. Jizan is the port for Aseer. Najd is the central highland of Arabia with a mean elevation of 3000 feet. The dominant feature of its topography is the mountain system called Tuwayq.
Riyadh, the capital of the kingdom, is in Najd.
