King of Saudi Arabia in the context of "Saudi royal family"

Masjid al-Haram (Arabic: المسجد الحرام, romanized: al-Masjid al-Ḥarām, lit. 'The Sacred Mosque'), also known as the Sacred Mosque or the Great Mosque of Mecca, is considered to be the most significant mosque in Islam. It encloses the vicinity of the Kaaba in Mecca, in the western region of Saudi Arabia. It is among the pilgrimage sites associated with the Hajj, which every Muslim must perform at least once in their lives if able. It is also the main site for the performance of ʿUmrah, the lesser pilgrimage that can be undertaken any time of the year. The rites of both pilgrimages include circumambulating the Kaaba within the mosque. The Great Mosque contains other important sites, such as the Black Stone, the Zamzam Well, Maqam Ibrahim, and the hills of Safa and Marwa.

As of 2025, the Great Mosque is both the largest mosque in the world, and the most expensive building in the world. It has undergone major renovations and expansions through the years. It has passed through the control of various caliphs, sultans and kings, and is now under the control of the King of Saudi Arabia who is titled the Custodian of the Two Holy Mosques.

The Prophet's Mosque (Arabic: ٱلْمَسْجِد ٱلنَّبَوِي‎, romanized: al-Masjid al-Nabawī, lit. 'Mosque of the Prophet') is the second mosque built by the Islamic prophet Muhammad in Medina, after the Quba Mosque, as well as the second largest mosque and holiest site in Islam, after the Masjid al-Haram in Mecca, in the Saudi region of the Hejaz. The mosque is located at the heart of Medina, and is a major site of pilgrimage that falls under the purview of the Custodian of the Two Holy Mosques (a royal style used by the King of Saudi Arabia.)

Muhammad himself was involved in the construction of the mosque. At the time, the mosque's land belonged to two young orphans, Sahl and Suhayl, and when they learned that Muhammad wished to acquire their land to erect a mosque, they went to Muhammad and offered the land to him as a gift; Muhammad insisted on paying a price for the land because they were orphaned children. The price agreed upon was paid by Abu Ayyub al-Ansari, who thus became the endower or donor (Arabic: وَاقِف, romanized: wāqif) of the mosque, on behalf or in favor of Muhammad. al-Ansari also accommodated Muhammad upon his arrival at Medina in 622.

The Custodian of the Two Holy Mosques (abbreviated as CTHM; Arabic: خَادِمُ ٱلْحَرَمَيْنِ ٱلشَّرِيفَيْنِ, romanized: Khādim al-Ḥaramayn aš-Šarīfayn, lit. 'Servant of the Two Noble Sanctuaries'), or Protector of the Two Holy Cities, is a royal style that has been used officially by the monarchs of Saudi Arabia since 1986. The title has historically been used by many Muslim rulers in the past, including the Ayyubids, the Mamluks, the Ottomans and the Sharifain rulers of Hejaz. The title was sometimes regarded to denote the de facto Caliph of Islam, but it mainly refers to the ruler taking the responsibility of guarding and maintaining the two holiest mosques in Islam: Al-Haram Mosque (Arabic: اَلْمَسْجِدُ ٱلْحَرَامُ, romanized: Al-Masjid al-Ḥarām, 'The Sacred Mosque') in Mecca and the Prophet's Mosque (Arabic: اَلْمَسْجِدُ ٱلنَّبَوِيُّ, romanized: Al-Masjid an-Nabawī) in Medina, both of which are in the Hejazi region of Saudi Arabia. The Custodian has been named the most powerful and influential person in Islam and the Sunni branch of Islam by The Muslim 500, as well as the most powerful Muslim and Arab ruler in the world.

The House of Saud (Arabic: آل سُعُود, romanized: ʾĀl Suʿūd IPA: [ʔaːl sʊʕuːd]) is the ruling royal family of Saudi Arabia. It is composed of the descendants of Muhammad bin Saud, founder of the Emirate of Diriyah, known as the First Saudi State, (1727–1818), and his brothers, though the ruling faction of the family is primarily led by the descendants of Ibn Saud, the modern founder of Saudi Arabia. It forms a subtribe of the larger prominent ancient Banu Hanifa tribe of Arabia, from which well known 7th century Arabian theologist Maslama ibn Ḥabīb originates. The most influential position of the royal family is the King of Saudi Arabia, an absolute monarch. The family in total is estimated to comprise 15,000 members; however, the majority of power, influence and wealth is possessed by a group of about 2,000 of them. Some estimates of the royal family's wealth measure their net worth at $1.4 trillion. This figure includes the market capitalization of Saudi Aramco, the state oil and gas company, and its vast assets in fossil fuel reserves, making them the wealthiest family in the world and the wealthiest in recorded history.

The House of Saud has had four phases: the Sheikhdom of Diriyah (1446–1744); the Emirate of Diriyah (1727–1818), marked by the expansion of Salafism; the Emirate of Nejd (1824–1891), marked with continuous infighting; and the current state (1902–present), which evolved into the Kingdom of Saudi Arabia in 1932 and now wields considerable influence in the Middle East. The family has had conflicts with the Ottoman Empire, the Sharif of Mecca, the Al Rashid family of Ha'il and their vassal houses in Najd along with numerous Islamist groups both inside and outside Saudi Arabia and Shia minority in Saudi Arabia.

Abdulaziz bin Abdul Rahman Al Saud (Arabic: عبد العزيز بن عبد الرحمن آل سعود; 15 January 1876 – 9 November 1953), known in the Western world as Ibn Saud (Arabic: ابن سعود; Ibn Suʿūd), was a Najdi statesman and tribal leader who became the founder and first king of Saudi Arabia, reigning from 23 September 1932 until his death in 1953. He had ruled parts of the kingdom since 1902, having previously been Emir, Sultan, King of Nejd, and King of Hejaz.

Ibn Saud was the son of Abdul Rahman bin Faisal, Emir of Nejd, and Sara bint Ahmed Al Sudairi. The family were exiled from their residence in the city of Riyadh in 1890. Ibn Saud reconquered Riyadh in 1902, starting three decades of conquests that made him the ruler of nearly all of central and north Arabia. He consolidated his control over Najd in 1921, then conquered the Hejaz in 1925. He extended his dominions into what later became the Kingdom of Saudi Arabia in 1932. Ibn Saud's victory and his support for Islamic revivalists would greatly bolster pan-Islamism across the Islamic world. Concording with Wahhabi beliefs, he ordered the demolition of several shrines, the Al-Baqi Cemetery and the Jannat al-Mu'alla. As King, he presided over the discovery of petroleum in Saudi Arabia in 1938 and the beginning of large-scale oil production after World War II. He fathered many children, including 45 sons, and all of the subsequent kings of Saudi Arabia as of 2025.
