The Iraqi Revolt began in Baghdad in the summer of 1920 with mass demonstrations by Iraqis, including protests by embittered officers from the old Ottoman Army, against the British who published the new land ownership and the burial taxes at Najaf. The revolt gained momentum when it spread to the largely tribal Shia regions of the middle and lower Euphrates. Sheikh Mehdi Al-Khalissi was a prominent Shia leader of the revolt. Using heavy artillery and aerial bombardment, the uprising was suppressed by the British.

The Sharifian or Sherifian Solution, was an informal name for post-Ottoman British Middle East policy and French Middle East policy of nation-building. As first put forward by T. E. Lawrence in 1918, it was a plan to install the three younger sons of Hussein bin Ali al-Hashimi as heads of state in newly created countries across the Middle East, whereby his second son Abdullah would rule Baghdad and Lower Mesopotamia, his third son Faisal would rule Syria, and his fourth son Zeid would rule Upper Mesopotamia. Hussein himself would not wield any political power in these places, and his first son, Ali would be his successor in Hejaz.
