context: The Brotherhood rebellion or the Brotherhood revolution is an armed rebellion led by some Brotherhood tribal leaders against the King of the Hejaz Kingdom and Najd and its annexes, Abdul Aziz Al Saud. The first prelude to the rebellion began in 1926 after the end of the Hijaz war in Hijaz (1924-1925), which eliminated the Kingdom of Hijaz, where the Brotherhood wanted to launch raids on the desert of Iraq and Kuwait in defiance of King Abdulaziz’s orders to stop the attacks since the Najd Sultanate is committed to preventing The invasion between the tribes of Najd and Iraq, according to the Treaty of Bahra signed in 1925. But King Abdulaziz was unable to prevent the Brotherhood from invading until the winter of 1929, when Ibn Badjad’s forces attacked Najdi camel merchants from Qassim and Shammar Najd, and this attack caused great resentment in Najd Which called on King Abdulaziz to rally his forces in Al-Zulfi on March 5th Most of Najd, Shammar, Harb, and Qahtan tribes joined him, while the Duwish and Ibn Baddad forces gathered in Jarab, north of Zulfi. King Abdulaziz sent one of the elders of the religion to Ibn Bajad to persuade him to lift the dispute regarding the massacres committed by his forces against camel merchants and the stolen goods that were looted to a religious court to adjudicate it, but Ibn Bjad refused the offer on the pretext that this is only a conspiracy against him and that his end is known in advance where he saw The clergy are friends of Ibn Saud and they will pass a death sentence. When the Brotherhood insisted on their position, King Abdulaziz ordered his forces to attack the Brotherhood on March 29, 1929 [1] and the Duwais were severely wounded and the King pledged to keep his life provided that they were subject to Sharia rule and allowed him to return to Artawyah and be treated to surrender to Riyadh after his recovery [2] While Ibn Badjad surrendered in Shaqra and imprisoned in Riyadh.
