Abdullah bin Abdullah Al Saud
Abdullah bin Abdullah Al Saud (; born July 1843) was a member of the Al Thunayan family, a branch of the House of Saud. He was a son of Abdullah bin Thunayan, Emir of Nejd. Abdullah bin Abdullah was born in July 1843, on the day his father Abdullah bin Thunayan died. As an adult, he made attempts to rebuild the Second Saudi State that his ancestors had ruled over. He eventually ended up in the Ottoman capital of Constantinople, where he ostensibly spent the rest of his life. Abdullah married a Turkish Circassian woman and  had six children. He was the father of Ahmed bin Abdullah Al Thunayan, advisor to King Abdulaziz of Saudi Arabia (founder of the Third Saudi State, the Kingdom of Saudi Arabia). Through his son Mohammad, Abdullah was the grandfather of Iffat bint Mohammad Al Thunayan, the consort of King Faisal. Queen Iffat was a prominent education activist in Saudi Arabia. Life. Abdullah bin Abdullah's father, Abdullah bin Thunayan, was Emir of Nejd from 1841 to 1843. In 1843 his cousin Faisal bin Turki overthrew him and imprisoned him in Al Masmak fort, where Abdullah bin Thunayan died in July  of that year. One of his sons was born the same day he died, and was therefore named Abdullah after his father. In 1879 Abdullah bin Abdullah headed to Constantinople, hoping to gain control over territory in the Al-Hasa region which the Ottomans had seized from his Al Saud relatives. While he was going towards Constantinople he sought the support of British authorities in Damascus and Cairo, among other places, but nothing came of this. Little is known about Abdullah after he reached Constantinople in August 1880, where he became known as "Abdullah Pasha" ( "ʿAbd Allāh Bāshā"). Family. While  he was in Constantinople, Abdullah married a Circassian woman named Tazeruh and together they had four children, Mohammad Saud, the twins Ahmed and Al Jawhara, and Sulaiman. He also had two sons from a second marriage named Abdul Rahman and Abdul Qadir. Abdullah's son Mohammad became a physician in the Ottoman army and was the father of Queen Iffat, the wife of King Faisal. Another of his sons, Ahmed, was an advisor to King Abdulaziz.
