Al-Malik Al-Aziz Uthman ibn Salah Ad-Din Yusuf (1171 – 29 November 1198) was the second Ayyubid Sultan of Egypt.
[2] Despite Al-Aziz having specifically inherited suzerainty over the whole Ayyubid empire, soon he had to face revolts by the Zengid emirs of Mosul and by the Artuqids in southern Iraq.
When Al-Afdal expelled all the ministers left by his father to support him, they came to Egypt, asking Al-Aziz to reconquer Syria.
Al-Afdal asked for help from Saladin's brother, Al-Adil I, who met Al-Aziz and managed to bring about a reconciliation.
During his reign, Al-Aziz tried to demolish the Great Pyramids of Giza, Egypt, but had to give up because the task was too big.
