Saudi Arabia is the largest Arab country of the Middle East. It is bordered by Jordan and Iraq on the north and northeast, Kuwait, Qatar, Bahrain and the United Arab Emirates on the east, Oman on the southeast, and Yemen on the south. The Persian Gulf lies to the northeast and the Red Sea to its west. It has an estimated population of 28 million, and its size is approximately 2,149,690 square kilometres.The Kingdom is sometimes called "The Land of the Two Holy Mosques" in reference to Mecca and Medina, the two holiest places in Islam.  The  two mosques are Masjid al-

Haram and Masjid Al-Nabawi. The current Kingdom was founded by Abdul-Aziz bin Saud, whose efforts began in 1902 when he captured the Al-Saud’s ancestral home of Riyadh, and culminated in 1932 with the proclamation and recognition of the Kingdom of Saudi Arabia, though its national origins go back as far as 1744 with the establishment of the First Saudi State.Petroleum exports fuel the Saudi economy.Oil accounts for more than 90 percent of exports and nearly 75 percent of government revenues.

The first Saudi State was established in 1756 when Muhammad ibn Abd-al-Wahhab settled in Diriyah and Prince Muhammed Ibn Saud agreed to support and espouse his cause in the hope of cleansing Islamic practices of heresy. The House of Saud and its allies rose to become  the  dominant  state in Arabia controlling most of the present-

day territory of Saudi Arabia, including the Islamic holy cities of Mecca and Medina.Concerned at the growing power of the Saudis, the Ottoman Sultan instructed Mohammed Ali Pasha to reconquer the area again. Ali sent his sons Tusun Pasha and Ibrahim Pasha who were successful in routing the Saudi forces in 1818.After a rebuilding period following the ending of the First Saudi State, the House of Saud returned to power in the Second Saudi State in 1824. The state lasted until 1891 when it succumbed to the Al Rashid of Ha'il.
