Salah ad-Din Ayyubi played a crucial role in the transition of power from the Fatimid Caliphate to the Ayyubid dynasty, marking the end of the Shia Fatimid rule in  Egypt . Appointed as vizier of Egypt by the Fatimid Caliph al-Adid in 1169, Saladin swiftly consolidated power, reformed the administration and strengthened the military.
