Emirate of Riyadh
The Emirate of Riyadh was the first iteration of the Third Saudi State from 1902 to 1913. It was a monarchy led by the House of Saud. The state was formed after Saudi forces seized Riyadh from the control of the Emirate of Ha'il, led by the House of Rashid, during the Battle of Riyadh. It was the direct antecedent of the Emirate of Nejd and Hasa, and the earliest legal predecessor of present-day Saudi Arabia. Al-Hasa was conquered in 1913. See also
