In 1902, Abdulaziz Ibn Saud succeeded in recapturing Riyadh for the House of Saud, and began a campaign to reconquer the region – a campaign which turned out to be highly successful for the Saudis. After several clashes, the Rashīdis and Saudis engaged into a full scale war over the region of Qassim, which resulted in a painful defeat for the Rashīdis and the death of the Rashīdi emir Abdul Aziz ibn Mitaab al-Rashīd.
