Saudi Arabia was founded in 1932 by Ibn Saud. The country is ruled under an "absolute monarchy," which is a form of monarchy in which one ruler has supreme authority that is unrestricted by any laws.
The country is ruled under the ultraconservative Wahhabi religious movement within Sunni Islam. Saudi Arabia hosts the two holiest places in Islam, the Al-Masjid al-Haram in Mecca and the Al-Masjid an-Nabawi in Medina.
It is a sovereign Arab state covering majority of the Arabian Peninsula, with a land mass of approximately 2,150,000 km2. The country has a population of 28.7 million people and the official language spoken is Arabic.
Petroleum was discovered on 3 March, 1938 in Saudi Arabia and has since become the world's largest oil producer and exporter. It is the only Arab country to be part of the G-20 major economies.
