بنو خالد
The town came under threat by the Wahhabi from 1780 onward due to the intermittent raids launched on the Bani Khalid strongholds in Al-Hasa. The Wahhabi speculated that the population of Zubarah would conspire against their regime with the help of the Bani Khalid. They also believed that its residents practiced teachings contrary to the Wahhabi doctrine, and regarded the town as an important gateway to the Persian Gulf. Saudi general Sulaiman ibn Ufaysan led a raid against the town in 1787. Five years later, a massive Wahhabi force conquered Al Hasa, forcing many refugees to flee to Zubarah. Wahhabi forces besieged Zubarah and several neighboring settlements in 1794 later as punishment for accommodating asylum seekers. The local chieftains were allowed to continue carrying out administrative tasks but were required to pay a tax.
