Decline and Revival  Saud's successor, his son Abdullah (who
ruled until 1818 - 1234 AH), was unable to halt the Egyptian
advance. Ad-Dar'iyah was taken and Abdullah bin Saud removed to
Istanbul where his captors executed him. Riyadh was captured in
1818 (1234 AH).  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.  Related Items Main reference point:
