Khawarij movement
The Khawarij, a radical Islamic group formed after the death of Muhammad in what would be today Saudi Arabia, was responsible for the revolt against Caliph Ali. However, some of them, following the more moderate and disagreed with the Khawarij, refused the authority of Khawarij and moved into South Arabia, which would be today Oman. Thus, the moderate party formed the Ibadi movement, in which later became the core of Omani culture. The Ibadi is the only surviving force of the Khawarij movement.

Modern relations
As both Oman and Saudi Arabia's modern political approach formed amidst the withdrawal of British Armed Forces, they established relationship at 1971. However, Oman has chosen a moderate approach in political agenda in comparison to Saudi Arabia. Oman has been acting as a mediator that keeping relationship with Iran when Iran has tensions with other Arab countries, and since then has become a bridge connecting relationship between two countries. Also, Oman is not a member of the Saudi-led coalition in the Yemeni Civil War. Instead, the Omani government has prioritized diplomatic resolution of tensions. In September 2023, cease-fire talks with the Houthi leadership began in Riyadh with Omani involvement.
