At the creation of the Sykes-Picot Agreement, the Hashemites ruled the kingdoms of Hijaz, Transjordan and Iraq. Once Ibn Saud established dominance in central Arabian Najd, he then proceeded to dominate much of the Arabian Peninsula and, with the help of the highly conservative Ikhwani forces, even conquered the Hashemite Kingdom of Hijaz in 1925. This was the beginning of an ideological struggle between the more conservative Salafi Islam (under Hanbali jurisprudence) and the Hanafi Islam practiced by the ruling Hashemite tribe in Iraq and Jordan.
