But excitement is also <a href="https://www.thenationalnews.com/gulf-news/2023/05/24/royal-wedding-fever-in-saudi-arabia-before-prince-husseins-marriage-to-rajwa-al-saif/">building in neighbouring Saudi Arabia</a>, the home country of the bride. The future princess of Jordan is not only a Saudi citizen but has family connections to the ruling Saudi royal family. She is connected to the Al Sauds through another of Saudi Arabia's most influential families – the Sudairis. Here's everything you need to know about her roots. Rajwa Al Saif is the daughter of Saudi businessman Khalid Al Saif and Azza Al Sudairi. Through her mother, she can trace her roots back to one of the most influential women in the kingdom's history, Hussa bint Ahmed Al Sudairi, known as the “mother of kings”. Hussa bint Ahmed (1900-1969) is Rajwa Al Saif's great-grand-aunt and was the seventh wife of the founder of the Kingdom of Saudi Arabia, King Abdulaziz. Their marriage helped solidify already close connections between the ruling Al Saud and the prominent Al Sudairi families – King Abdulaziz's mother, Sara bint Ahmed, also came from the Al Sudairi tribe. King Abdulaziz, who ruled from 1902 until his death in 1953, is thought to have had about 100 children from dozens of wives and concubines. These included seven sons with Hussa bint Ahmed, who were among King Abdulaziz's favourites and came to be known as the “<a href="https://www.thenationalnews.com/world/mena/prince-salman-named-heir-to-saudi-throne-1.382432">Sudairi Seven</a>” due to their prominence in the Saudi royal family. Two of them – Fahd and Salman – ruled as kings of Saudi Arabia, while two others – <a href="https://www.thenationalnews.com/world/mena/saudi-crown-prince-mourned-1.435474">Sultan</a> and <a href="https://www.thenationalnews.com/world/mena/prince-nayef-bin-abdulaziz-al-saud-named-saudi-crown-prince-1.412584">Nayef</a> – became crown princes. “The Sudairis were the powerhouse at the heart of the Al Saud, owing partly to their numbers (no other grouping of blood brothers numbered more than three), but mainly to their mutual loyalty, ambition and extraordinary appetite for work – qualities instilled in them by their mother,” historian Robert Lacey wrote in his book <i>Inside the Kingdom</i>. “To her dying day, the formidable Hussa insisted that all seven of her boys, no matter how grand they had become, should gather in her home once a week for lunch.” Hussa bint Ahmed was the daughter of Ahmed bin Mohammed Al Sudairi, a pivotal figure considered by many to have been one of King Abdulaziz’s right-hand men <a href="https://www.thenationalnews.com/gulf-news/saudi-arabia/2022/01/13/the-capture-of-riyadh-1902-how-a-daring-raid-shaped-arabia/">during his conquest of Arabia</a> and foundation of the third state of the Kingdom of Saudi Arabia. Rajwa's mother's grandfather, Abdulaziz bin Ahmed Al Sudairi, was the “mother of kings” Hussa bin Ahmed's brother. Abdulaziz had run Al Jouf province, before being appointed governor of Al Qurayyat city. Later, King Abdulaziz named him the emir of the Al Qurayyat region, giving him responsibility for all of the north-western border strip of the kingdom at a time when the neighbouring governments of the region were riven with rivalry. Like the Al Saud, the Al Sudairi hail from the Najd region of central Arabia. Their lineage can be traced back to the Badarin line of the wider Al Dawasir clan in Arabia. The tribe was considered a “sharifian” or noble tribe that lived on the edge of the Rub Al Khali desert in about 1400. Nearly 150 years later, the Al Sudairi ruled the town of Al Ghat in Sudair, an area in Najd north-west of Riyadh which took its name from the tribe. History lecturer and Ahmed Al Arf at Al Qassim University, who has studied and traced the history of the Al Sudairi tribe, said the family contributed heavily during all three eras of the states of Saudi Arabia. “The Al Sudairi tribe from the town of Al Ghat played a pivotal role during the first, second and third states of the country. The first Ahmed bin Mohammed Al Sudairi was the father of Sara bint Ahmed who married King Abdulaziz. The second Ahmed Al Sudairi gave birth to Abdulaziz and Hussa, both of whom would play a role through their relation to King Abdulaziz during the third state of the country,” he said in a documentary. With this background, Rajwa Al Saif's marriage to Crown Prince Hussein across the border in Jordan has generated considerable interest in Saudi Arabia. Her engagement to Crown Prince Hussein took place in her father's home in Riyadh in August. The ceremony will take place at Zahran Palace before the wedding procession moves to Al Husseiniya Palace. In tying the knot at Zahran Palace, the couple will be following in the footsteps of many members of the <a href="https://www.thenationalnews.com/lifestyle/2023/03/14/jordan-royal-weddings/">Jordanian royal family</a>. Built in 1957, Zahran Palace was the home of the late Queen Zein Al Sharaf, mother of the late King Hussein. <b>A wedding venue steeped in royal history</b> In tying the knot at Zahran Palace, the couple will be following in the footsteps of many members of the <a href="https://www.thenationalnews.com/lifestyle/2023/03/14/jordan-royal-weddings/">Jordanian royal family</a>. Built in 1957, Zahran Palace was the home of the late Queen Zein Al Sharaf, mother of the late King Hussein. The word “zahran” originates from the Arabic for “blooming flower”, which fits with the palace’s lush green grounds. It overlooks a boulevard in Jabal Amman where many of the city’s embassies are located. It was at Zahran Palace where Crown Prince Hussein’s parents, King Abdullah II and <a href="https://www.thenationalnews.com/lifestyle/fashion-beauty/2023/05/06/queen-rania-of-jordan-wears-elegant-fitted-pastel-dress-at-coronation/">Queen Rania</a>, were married in 1993. The couple, who will celebrate their 30th wedding anniversary on June 10, just days after their son’s nuptials, left Zahran Palace in an open-top car, before taking part in a procession through the streets of Amman, where they waved to waiting crowds. Zahran Palace also hosted the wedding of King Hussein to Antoinette Gardiner in 1961, as well the wedding of Jordan's former Crown Prince Hamzah bin Al Hussein and Princess Noor Hamzah. This year is set to be a busy one for the Jordanian royal family, with two weddings taking place.

Dina became the Queen of Jordan after the pair’s wedding, and 10 months later, on February, 13, 1956, she gave birth to the king's first child, Princess Alia. However, the marriage ended in divorce in 1957, after which Dina became known as HRH Princess Dina Abdul-Hamid of Jordan. <b>1961: King Hussein and Antoinette Gardiner</b> Four years after the end of his first marriage, King Hussein married second wife, Antoinette Gardiner, on May 29, 1961.
