Otaibah (Arabic: عتيبة; also spelled Otaiba, Utaybah and Otaibi for singular) is one of the largest predominantly Sunni Arab tribes in the Arabian Peninsula. Today, they are mostly found in Saudi Arabia, Iraq, Kuwait, Qatar, United Arab Emirates, Jordan, Palestine and Syria.
Otaibah are originally from Hejaz and Najd. They have ruled Najd For a long time the tribe maintained a cooperative attitude towards the Ikhwan movement championed by the Al Saud clan of Nejd in the 18th and 19th centuries, and tended to side more with the Sharifs of Mecca. In 1912, however, the founder of modern Saudi Arabia, Abdul Aziz Ibn Saud, began an ambitious plan to settle the nomadic tribes within his domains (which at the time included Nejd and Arabia's eastern coastal areas). That Was coupled with indoctrination of the tribesmen into the religious ideals espoused by Muhammad ibn Abd Al-Wahhab, as the religious observance of the bedouin was hitherto considered to be somewhat loose. The new settlements were to be known as hijras and the accompanying religious movement was called Ikhwan ("the brothers"). As a result, a large number of 'Utaybi hijras sprung up across the land, especially in western Nejd. The most famous 'Utaybi hijras were 'Afif near Dwadmi, and Sajir near Shaqraa. A large contingent of 'Utaybah, led by Sultan ibn Bjad Bin Humaid aka Sultanaldeen, and also Eqab bin Mohaya Alotaibi (عقاب بن محيا) was one of the most influential leaders. Moreover, Eqab bin Mohaya belonged to [[lkhwan]] movement, and he was the head of his tribe(Talhah). Sultan bin Bajad joined the Ikhwan and became the leader of Ikhwan, who were then deployed by Ibn Saud against his rivals as he sought to unite as much of Arabia under his rule as possible. The Ikhwan were instrumental in gaining control of the Hejaz for Ibn Saud, but they then grew resentful and restless. The 'Utaybi leader of Ikhwan joined with main Ikhwan leaders from other tribes in revolt, but they were defeated by Ibn Saud's forces at the Battle of Sabilla near Al Zulfi in northeastern Nejd in 1930. The 'Utaybi hijras remained, however, and the hijra of 'Afif became particularly prosperous and is now considered a city in its own right, lying approximately halfway between Riyadh and Mecca.
