Wahhabi sack of Karbala
The Wahhabi sack of Karbala (Arabic: الهجوم الوهابي على كربلاء) occurred on 21 April 1802, under the rule of Abdulaziz bin Muhammad Al Saud, the second ruler of the Emirate of Diriyah, where approximately 12,000 Wahhabis from Najd attacked the Shia city of Karbala in Ottoman Iraq. The raid was conducted in retaliation against attacks on Hajj caravans by Iraqi tribes and coincided with the anniversary of Ghadir Khumm.
