Saudi Arabia country profile

The Kingdom of Saudi Arabia is one of the main players in the Arab world.

Its stature is built on its prestige as the custodian of the birthplace of Islam, and its status as an one of the world's largest oil producers.

Its importance as an oil exporter has made economic interdependence with the West - where the main consumer demand is found - a necessity.

This, in turn, has led to strong political and military relationships that at times have been a source of awkwardness for both sides.

It stands out for its espousal of a puritan version of Sunni Islam, including harsh punishments such as public beheadings, and its restrictions on the rights of women.

In recent years, there has been a growing regional rivalry with Iran.

King Salman bin Abdulaziz al-Saud

The Al Saud dynasty holds a monopoly of political power. King Salman bin Abdulaziz al-Saud ascended the throne in January 2015 following the death of his half-brother Abdullah.

He has been part of the ruling group of princes for decades, and has continued the main thrusts of Saudi strategic policy - maintaining the US alliance and working towards energy market stability.

Crown prince: Mohammed bin Salman

King Salman made his son Mohammed bin Salman heir-apparent in June 2017, and the latter now controls all the major levers of power.

There are no democratic institutions in Saudi Arabia, with the systematic repression of human rights activists, women's rights activists, journalists and political dissidents.

The crown prince was personally linked to the assassination of Saudi Arabian Washington Post columnist Jamal Khashoggi, who had criticised the Saudi government. He has denied involvement in the killing.

Saudi investors are major players in the pan-Arab TV industry, but the country has one of the region's most tightly-controlled media environments.

The government openly acknowledges that widespread internet filtering takes place. It targets "pornographic", Islam-related, human rights and political sites.

Saudi Arabia has the highest per-capita YouTube use of any country in the world. It is reportedly home to more than 40% of all active Twitter users in the Arab region.
