Mani' ibn Rabi'a al-Muraydi (Arabic: مانع بن ربيعة المريدي; 24 October 1400 – 14 August 1463) is the oldest recorded ancestor of the House of Saud, which currently rules in the Kingdom of Saudi Arabia.
He was a member of the Mrudah clan.[1] The Mrudah are believed to be descended from the Banu Hanifa branch of the larger Rabi'ah tribal confederation. [1]
His original residence was the village of al-Duru', near the town of al-Qatif on the East Arabia coast.[2]
In 1446, he visited his relative Ibn Dir'a in the village of Manfuha, near the city of Hajr (Riyadh) in Central Arabia. Mani' ibn Rabi'a later acquired land in Ghusayba and al-Mulaybeed, later merged and developed into a city called Diriyah, which became the forerunner of this family's territory.[2]
Between 1654 and 1726, there was a fierce rivalry between his descendants, namely the Al-Watban branch (descendants of Watban ibn Rabi'a) against the Al-Muqrin branch (descendants of Muqrin ibn Markhan), as well as wars against other rulers around Diriyah. The Al-Muqrin branch under the leadership of Muhammad ibn Saud finally managed to consolidate power, by forging a close fellowship with Shaykh Muhammad ibn Abd al-Wahhab, to form the First Saudi State which manifested in 1744.[3]
