He joined alliances with foreign tribes and revolted against his half-brother Abdullah. His rule was short-lived and Abdullah overthrew him. Saud gained power again in 1873 but died two years later. His reign was notable for the infighting in the House of Saud which he initiated.

Prince Saud was one of the most known Najdi people. Through his marriages he was the brother-in-law, and later a son-in-law, of King Abdulaziz. Saud was married for 45 years to King Abdulaziz's eldest sister Noura bint Abdul Rahman, and after her death in 1950 he married the King's daughter Princess Hessa.

Faisal bin Sultan al-Duwaish was Prince of the Mutair tribe and one of Arabia's Ikhwan leaders, who assisted Abdulaziz in the unification of Saudi Arabia. The mother of Faisal bin Sultan was from the Ajman tribe and the sister of Dhaydan bin Hithlain, another Ikhwan leader and sheikh of the Ajman tribe.
The Unification of Saudi Arabia was a military and political campaign in which the various tribes, sheikhdoms, city-states, emirates, and kingdoms of most of the central Arabian Peninsula were conquered by the House of Saud, or Al Saud. Unification started in 1902 and continued until 1932, when the Kingdom of Saudi Arabia was proclaimed under the leadership of Abdulaziz, known in the West as Ibn Saud, creating what is sometimes referred to as the Third Saudi State, to differentiate it from the Emirate of Diriyah, the First Saudi State and the Emirate of Nejd, the Second Saudi State, also House of Saud states.

Sultan bin Bajad bin Humaid al-'Utaybi was the Sheikh of the Otaibah tribe and one of the prominent leaders of the Ikhwan movement in the Arabian Peninsula. This tribal army supported King Abdulaziz in his efforts to unify Saudi Arabia between 1910 and 1927.
The Battle of Sabilla was the main battle of the Ikhwan revolt in northern Arabia between the rebellious Ikhwan forces and the army of Abdulaziz al-Saud. It was the last tribal uprising in Arabia. It was also the last major battle in which one side rode camels, as the Ikhwan emphasized radical conservatism and shunned technological modernization.
The Ikhwan revolt was an uprising in the Arabian Peninsula from 1927 to 1930 led by the Ikhwan. It began in 1927, when the tribesmen of the Otaibah, Mutayr and Ajman rebelled against the authority of Ibn Saud and engaged in cross-border raids into parts of Transjordan, Mandatory Iraq and the Sheikhdom of Kuwait. The relationship between the House of Saud and the Ikhwan deteriorated into an open bloody feud in December 1928. The main instigators of the rebellion were defeated in the Battle of Sabilla, on 29 March 1929. Ikhwan tribesmen and troops loyal to Abdulaziz clashed again in the Jabal Shammar region in August 1929, and Ikhwan tribesmen attacked the Awazim tribe on 5 October 1929. Faisal al-Duwaish, the main leader of the rebellion and the Mutair tribe, fled to Kuwait in October 1929 before being detained by the British and handed over to Ibn Saud. Al-Duwaish would die in Riyadh on 3 October 1931 from an apparent heart condition. Government troops had finally suppressed the rebellion on 10 January 1930, when other Ikhwan rebel leaders surrendered to the British. In the aftermath, the Ikhwan leadership was slain, and the remains were eventually incorporated into regular Saudi units. Sultan bin Bajad, one of the three main Ikhwan leaders, was killed in 1931, while Al-Duwaish died in prison in Riyadh on 3 October 1931.
The Taif massacre was an incident that followed the short 1924 Battle of Taif; the entire episode is also known as the al-Taif incident. The battle and resultant massacre comprised the first major standoff of the Second Hashemite-Saudi War. Following a short siege, Taif was abandoned by Hashemite forces and then capitulated to the battle-ready Ikhwan force under the command of Abdulaziz Ibn Saud. The Ikhwan troops took out their rage on the residents of the city. In the resulting bloodbath, some 300-400 Ta'if residents were massacred.
The Conquest of al-Hasa was achieved by the forces of Ibn Saud with support from the Ikhwan in April 1913. The oasis of al-Hasa was conquered from an Ottoman garrison, which had controlled the area since 1871.

The Battle of Kanzan was a territorial battle between the Al Saud and their long-term enemies, the Ajman tribe, which began in June 1915 and lasted for nearly six months. The reason for the battle was the tribe resisting the Al Saud rule.
