Ibn Saud
In 1902, Ibn Saud took control of Riyadh in Nejd and brought the Al Saud back to Nejd. Ibn Saud gained the support of the Ikhwan, a tribal army inspired by Muhammad ibn Abd al-Wahhab and led by Sultan ibn Bijad and Faisal Al-Dawish, and which had grown quickly after its foundation in 1912. With the aid of the Ikhwan, Ibn Saud captured al-Hasa from the Ottomans in 1913.
