What did Isma'il do that enraged the O Ottomans?

Answer 1

Isma'il, the founder of the Safavid dynasty in Persia, enraged the Ottomans primarily by promoting Shia Islam as the state religion, which directly challenged the Sunni orthodoxy of the Ottoman Empire. His military campaigns against Ottoman territories and his aggressive expansionist policies further heightened tensions. Additionally, Isma'il's declaration of himself as the Shah of Iran and his efforts to unify Persia under Shia Islam were seen as a direct affront to Ottoman authority and legitimacy, leading to a prolonged rivalry between the two empires.
