- Just before the battle of Chaldiran the shots taken by the Janissaries at the tent of Ottoman Sultan Selim I find their mark, killing him
-Ismail I routes the effectively leaderless Ottoman force which is forced to retreat. Artillery is acquired en masse as is gunpowder. Ottoman officers and artillerymen face a choice: work for the Shahshahnah or languish until a definitive peace is signed.
-First at the battle of Mosul in early 1515, then at the Siege of Batman, and again at the Battle of the Three Cities in early 1516 just after (Antioch, Iskendrun, Antakya), the Persian armies have used artillery and lack of definitive Ottoman leadership to turn the Tarsus Mountains and OTL Hatay area into the frontier between Shia and Sunni Islam instead of Mesopotamia
-This allows a much more favorable treaty for the Safavids who contain Ottoman expansion while starting to Persian-ize the region
