In 1766, members of the Al Khalifa family of the Utub tribal confederation migrated from Kuwait to Zubarah in Qatar. By the time of their arrival, the Bani Khalid exercised weak authority over the peninsula, notwithstanding the fact that the largest village was ruled by their distant kin. In 1783, Qatar-based Bani Utbah clans and allied Arab tribes invaded and annexed Bahrain from the Persians. The Al Khalifa imposed their authority over Bahrain and retained their jurisdiction over Zubarah.
