In pre-Islamic times, apart from a small number of urban trading settlements (such as Mecca and Medina), most of what was to become Saudi Arabia was populated by nomadic tribal societies in the inhospitable desert. The Islamic prophet, Muhammad, was born in Mecca in about 571 A.D. In the early 7th century, Muhammad united the various tribes of the peninsula and created a single Islamic religious polity. Following his death in 632, his followers rapidly expanded the territory under Muslim rule beyond Arabia, conquering huge swathes of territory (from the Iberian Peninsula in west to modern day Pakistan in east) in a matter of decades. In so doing, Arabia soon became a politically peripheral region of the Muslim world as the focus shifted to the more developed conquered lands. From the 10th century to the early 20th century Mecca and Medina were under the control of a local Arab ruler known as the Sharif of Mecca, but at most times the Sharif owed allegiance to the ruler of one of the major Islamic empires based in Baghdad, Cairo or Istanbul. Most of the remainder of what became Saudi Arabia reverted to traditional tribal rule.
Saudi Arabia is an absolute monarchy. However, according to the Basic Law of Saudi Arabia adopted by royal decree in 1992, the king must comply with Sharia (Islamic law) and the Quran, while the Quran and the Sunnah (the traditions of Muhammad) are declared to be the country's constitution. No political parties or national elections are permitted. The Economist rates the Saudi government as the fifth most authoritarian government out of 167 rated in its 2012 Democracy Index, and Freedom House gives it its lowest rating .
