Political change took place in Saudi Arabia due to oil. For example The politics of Saudi Arabia takes place in the context of an Islamic absolute monarchy. The King of Saudi Arabia is both head of state and the head of government, but decisions are, to a large extent, made on the basis of consultation among the senior princes of the royal family and the religious establishment. The Qur'an is declared to be the constitution of the country, which is governed on the basis of Islamic law. Another example is that Government is dominated by the vast royal family, the Al Saud, which has often been divided by internal disputes and into factions. The members of the family are the principle political actors. Political participation outside of the royal family is limited, but there has been pressure for some time to broaden participation.
