During his reign, the grasp of the House of Saud extended into Riyadh with Abdul Aziz's victory there and subsequent conquest. This victory allowed the House of Saud to rule all of Nejd. Their military success and orthodox approach to religion won them great support in the area. Their standing was also boosted by Abdul Aziz's practice of holding open meetings where tribal elders could meet with him, allowing access to their ruler.
One notable event of his reign were attacks on the shrines of Ali bin Abu Talib in Najaf, Iraq and on the shrine of Imam Husayn in Karbala, Iraq. This was done in 1802, and is not surprising considering the view in Wahhabism that opposes the building of shrines and which considers the Shia not to be Muslim (both shrines are very important to the Shia).
The House of Saud is also linked with Wahhabism through the marriage of the son of Muhammad ibn Saud with the daughter of Muhammad ibn Abd al Wahhab in 1744.
The Head of the House of Saud is the King of Saudi Arabia who serves as Head of State and monarch of the Kingdom of Saudi Arabia.
Sons of AbdulAziz (ibn Saud, the founder of the modern Saudi state) are from the AbdulAziz line of the family, and have been the only members allowed to serve as King or Crown Prince.

binMuhammad al Saud's reign was a period of religious cleansing in Arabia.
The forces of Saud also felt that they were emulating the example of Muhammad who smashed idols when he retook Mecca.
