Iranian Revival

Needs Legacy of Persia - the Iranian Resurgence ending of the Iranian Intermezzo. The wiki's power move: replace the Abbasid Caliph with a custom Persian-culture ruler, which both cancels the Caliphate's scripted opening war and hands you the region's dominant realm, making the struggle trivially steerable. Push Persian-heritage dominance through the struggle phases and take the Iranian Resurgence ending when it's available. One ending per campaign - the Abbasid endings (Abbasid Might, Shia Reborn, All Your Caliphate Are Belong To Us) each want their own run.
