Ikhwan

The Ikhwān (, ), commonly known as Ikhwān man Aṭāʿa Allāh (, 'Brethren of those who obey God'), was a Wahhabi religious militia made up of traditionally nomadic tribesmen which formed a significant military force of the ruler Ibn Saud and played an important role during the unification of Saudi Arabia whereby establishing him as ruler of most of the Arabian Peninsula in Kingdom of Saudi Arabia.

The Ikhwan first appeared around 1902. They were the product of clergy who aimed to break up the Bedouin tribes and settle them around the wells and oases of the sedentary Arabian populations, mainly those of the Najd, on the grounds that nomadic life was incompatible with the strict conformity of their interpretation of Islam. The newly Islamicized Bedouin would be converted from nomad raiders to soldiers for Islam. The cleric/teachers of the Ikhwan were dedicated to their idea of the purification and the unification of Islam, and some of the newly converted Ikhwan rebelled against their emir Ibn Saud, accusing him of religious laxity. The conquest of the Hejaz in 1924 brought all of the current Saudi state under Ibn Saud's control. The monarch then found himself in conflict with elements of the Ikhwan. He crushed their power at the Battle of Sabilla in 1929, following which the militia was reorganised into the Saudi Arabian National Guard.
