Abdullah bin Saud Al Kabeer

Abdullah bin Saud Al Saud was the last ruler of the First Saudi State, from 1814 to 1818, and was executed in Istanbul under the Ottoman Empire. Although the Ottomans maintained several garrisons in the Nejd thereafter, they were unable to prevent the rise of the Emirate of Nejd, also known as the Second Saudi State, led by Turki bin Abdullah.
