The Sudairi Seven (Arabic: السديريون السبعة, As Sudayriyyūn as Sabʿah), also spelled Sudairy or Sudayri, refers to a powerful alliance of seven full brothers within the Saudi royal family. They are also known as the Sudairi clan or the Sudairi faction.

• The Sudairi Seven were the sons of King Abdulaziz (also known as Ibn Saud), the founder of modern Saudi Arabia, and Hussa bint Ahmed Al Sudairi. King Abdulaziz had more sons with Hussa than with any of his other wives.

• King Abdulaziz married women from powerful Nejdi and other Arab families to solidify his control. One of these marriages was to Hussa bint Ahmed Al Sudairi, a member of the Al Sudairi clan. King Abdulaziz's mother, Sara bint Ahmed Al Sudairi, also belonged to the Al Sudairi family.

• The seven brothers, being full brothers, were able to exert significant coordinated influence and power.

The Sudairi Seven consisted of the following sons of King Abdulaziz and Hussa bint Ahmed Al Sudairi:

1. Fahd (1921–2005): King of Saudi Arabia (1982–2005)
2. Sultan (1928–2011): Crown Prince (2005–2011)
3. Abdul Rahman (1931–2017): Deputy Minister of Defense and Aviation (1978–2011)
4. Nayef (1934–2012): Crown Prince and First Deputy Prime Minister (2011–2012), Interior Minister (1975–2012)
5. Turki II (1934–2016): Deputy Defense Minister (1968–78)
6. Salman (born 1935): King of Saudi Arabia (2015–present)
7. Ahmed (born 1942): Deputy Minister of the Interior (1975–2012) and briefly as Minister of the Interior in 2012

The sisters of the Sudairi Seven were:

• Princess Luluwah (1928–2008)
• Princess Latifa (died September 2024)
• Princess Al Jawhara (died 2023)
• Princess Jawahir (died June 2015)

• Their influence grew significantly after Prince Fahd became Crown Prince in 1975 and subsequently King in 1982.

• The Sudairi Seven held key government posts, such as Minister of Interior, Minister of Defense, and Governor of Riyadh, allowing them to consolidate power.

• King Faisal relied heavily upon the seven Sudairi brothers. They collaborated with Crown Prince Faisal. They threatened five members of King Saud's cabinet to submit their resignations and, as prime minister and heir apparent, Prince Faisal appointed Prince Fahd as interior minister, Prince Sultan as defense minister, and Prince Salman as governor of Riyadh.

• Other princes and factions within the royal family quietly aligned against the Sudairi Seven due to their dominance.

• King Abdullah attempted to counter their power by creating the Allegiance Commission to determine future succession.

• With the death of some of the Sudairi brothers, the group's influence has evolved, but the remaining members, particularly King Salman and his branch, continue to hold significant power.

• King Salman's appointment of his son, Mohammed bin Salman (MBS), as Crown Prince has further solidified the Sudairi line's control over the kingdom. King Salman consolidated power on behalf of the clan.

• The Sudairi Seven played a crucial role in shaping modern Saudi Arabia, influencing its political landscape, and holding key positions within the government.

• Their rise to power brought continuity but also prompted internal rivalries within the royal family.
