The correct answer is: "Saladin "
Al-Nāsir Ṣalāḥ ad-Dīn Yūsuf ibn Ayyūb (in Kurdish, Selahedînê Eyûbî, in Arabic, صلاح الدين يوسف بن أيوب), better known in the West as Saladin, Saladin, Salahadin or Saladine (1138, Tikrit (Iraq) - March 4 of 1193, Damascus), was one of the great rulers of the Islamic world, being sultan of Egypt and Syria and including in its domains Palestine, Mesopotamia, Yemen, Hijaz and Libya. With him began the Ayyubid dynasty, which would rule Egypt and Syria after his death.
Defender of Islam and particularly of the religious orthodoxy represented by Sunnism, politically and religiously unified the Middle East by fighting and leading the fight against the Crusader Christians and ending doctrines far from the official Muslim cult represented by the Abbasid Caliphate. He is particularly known for having defeated the Crusaders in the Battle of Hattin, after which he again occupied Jerusalem for the Muslims and took the Holy Land. The impact of this event in the West led to the Third Crusade led by Richard I of England, which became mythical for both Westerners and Muslims.
His fame transcended the temporal and became a symbol of medieval chivalry, even for his enemies. He is still a much admired figure in Arab, Kurdish and Muslim religion.
