Saudi Arabia is the birthplace of Islam and home to Islam's two holiest shrines in Mecca and Medina. The king's official title is the Custodian of the Two Holy Mosques. The modern Saudi state was founded in 1932 by ABD AL-AZIZ bin Abd al-Rahman Al SAUD (Ibn Saud) after a 30-year campaign to unify most of the Arabian Peninsula. One of his male descendants rules the country today, as required by the country's 1992 Basic Law. Following Iraq's invasion of Kuwait in 1990, Saudi Arabia accepted the Kuwaiti royal family and 400,000 refugees while allowing Western and Arab troops to deploy on its soil for the liberation of Kuwait the following year. The continuing presence of foreign troops on Saudi soil after the liberation of Kuwait became a source of tension between the royal family and the public until all operational US troops left the country in 2003. Major terrorist attacks in May and November 2003 spurred a strong ongoing campaign against domestic terrorism and extremism.
From 2005 to 2015, King ABDALLAH incrementally modernized the Kingdom. Driven by personal ideology and political pragmatism, he introduced a series of social and economic initiatives, including expanding employment and social opportunities for women, attracting foreign investment, increasing the role of the private sector in the economy, and discouraging businesses from hiring foreign workers. Saudi Arabia saw some protests during the 2011 Arab Spring but not the level of bloodshed seen in protests elsewhere in the region. Shia Muslims in the Eastern Province protested primarily against the detention of political prisoners, endemic discrimination, and Bahraini and Saudi Government actions in Bahrain. Riyadh took a cautious but firm approach by arresting some protesters but releasing most of them quickly and by using its state-sponsored clerics to counter political and Islamist activism.
The government held its first-ever elections in 2005 and 2011, when Saudis went to the polls to elect municipal councilors. In December 2015, women were allowed to vote and stand as candidates for the first time in municipalmunicipal council elections, with 19 women winning seats. King SALMAN bin Abd al-Aziz Al Saud ascended to the throne in 2015 and placed the first next-generation prince, MUHAMMAD BIN NAIF bin Abd al-Aziz Al Saud, in the line of succession as Crown Prince. He designated his son, MUHAMMAD BIN SALMAN bin Abd al-Aziz Al Saud, as the Deputy Crown Prince. In March 2015, Saudi Arabia led a coalition of 10 countries in a military campaign to restore the legitimate government of Yemen, which had been ousted by Huthi forces allied with former president ALI ABDULLAH al-Salih. The war in Yemen has drawn international criticism for civilian casualties and its effect on the country’s dire humanitarian situation. In December 2015, then Deputy Crown Prince MUHAMMAD BIN SALMAN announced Saudi Arabia would lead a 34-nation Islamic Coalition to fight terrorism (it has since grown to 41 nations). In May 2017, Saudi Arabia inaugurated the Global Center for Combatting Extremist Ideology (also known as "Etidal") as part of its ongoing efforts to counter violent extremism. In June 2017, King SALMAN elevated MUHAMMAD BIN SALMAN to Crown Prince. In September 2017, King SALMAN issued a royal decree recognizing the right of Saudi women to drive beginning in June 2018.
The country remains a leading producer of oil and natural gas and holds about 16% of the world's proven oil reserves as of 2015. The government continues to pursue economic reform and diversification, particularly since Saudi Arabia's accession to the WTO in 2005, and promotes foreign investment in the Kingdom. In April 2016, the Saudi government announced a broad set of socio-economic reforms, known as Vision 2030. Low global oil prices throughout 2015 and 2016 significantly lowered Saudi Arabia’s governmental revenue. In response, the government cut subsidies on water, electricity, and gasoline; reduced government employee compensation packages; and announced limited new land taxes. In coordination with OPEC and some key non-OPEC countries, Saudi Arabia agreed cut oil output in early 2017 to regulate supply and help elevate global prices.
