From 1818 to 1824 (1234 to 1240 AH), the Ottoman Empire maintained a few garrisons in Nejd, as a gesture of their dominance. Thus, the first temporary decline in the House of Saud occurred. Within a few years, however, the fortunes of the House of Saud were to revive. In 1824 (1240 AH), Turki, a cousin of Saud bin Abdul Aziz, assumed the Amirship of Nejd. In the course of his rule (1824 to 1834 - 1240 to 1250 AH), Turki retook Riyadh and continued the Saudi drive for consolidation of the area.
