Historians disagree about the exact date of the arrival of the Utub or Bani Attaba in Kuwait. The Utub tribe comprised several groups from the tribe of Anaza, such as Al-Sabah, Al-Khalifa, Al-Zayed, Al-Halahima and Al-Muawida who migrated from Al-Aflag in Najd eventually settled in Kuwait after along migration. The Utub lived under the direct rule of Sheikh Bani Khalid. But the disputes over the succession, which started in the ruling family after the demise of Sadun bin Muhammad bin Ghurair Al-Hamid in 1722 gave the Utub and other tributary tribes some form of local independence. The rivalry among the factions of the ruling family was ended by the unanimous choice in 1753 of Sabah bin Jabir by the inhabitants of Kuwait to administer justice and the affairs of the town.
