I want to know the answer to the following question:
Ismail I forced a conversion to what Islamic branch?
All the background I'm provided with is that "Iran was predominantly Sunni, but Ismail instigated a forced conversion to the Shia branch of Islam, by which the Shia Islam spread throughout the Safavid territories in the Caucasus, Iran, Anatolia, and Mesopotamia.". Is that enough to answer the question?
