All Your Caliphate Are Belong To Us

Needs Legacy of Persia. The Dominate the Caliph foundation has two sneaky requirements beyond the Abbasid Humiliation ending: the Caliph must hold the Arabian Empire, and YOU must personally hold the County of Samarra (not via a vassal) for five years before the decision unlocks. The wiki start: Amiran Ya'qub of Makran, 867. Win the opening war, steer House Unity to Antagonistic for unlimited Subjugate Kingdom CBs, subjugate Mesopotamia and Jazira, and bite counties directly off the Caliph in the dense Levant rather than racing him for land. Outgrow the Abbasids, sit on Samarra for the five years, take the decision. One struggle resolution per campaign - Shia Reborn, Iranian Revival and Abbasid Might all need separate runs.
