Al-Malik Al-Aziz Osman bin Salahadin Yusuf (b.1171 d.1200), more commonly known as Al-Aziz Uthman' or Al-Malik, was the second son of Saladin and the second Ayyubid Sultan of Egypt.
Before his death, Saladin had divided his dominions amongst his kin - Al-Afdal received Syria, Palestine and the Yemen, Az-Zahri received Northern Syria and Abu Bakr Mesopotamia. This soon led to conflict, during which Abu Bakr, a brother of Saladin, managed to acquire lands from Mesopotamia to Egypt and to overthrow Al-Malik, taking the throne name Al-Malik Al-Adil I (1200-1218)
