Bani Khalid
Having expelled the Ottomans, the Bani Khalid held jurisdiction over Qatar from 1670 onward. In 1766, the Utub clans of Al Jalahma and Al Khalifa migrated from Kuwait to Zubarah in Qatar. By the time of their arrival in Zubarah, the Bani Khalid exercised weak power over Qatar, though the largest village was ruled by distant kin of the Bani Khalid. After the Persian Occupation of Basra in 1777 many merchants and families moved from Basra and Kuwait to Zubarah. The town became a thriving center of trade and pearling in the Persian Gulf region after this movement.
