He obeyed his orders, but he abolished the khalifate so quietly, the khalifa never even knew about it. One Friday, Saladin simply arranged for a citizen to get up in the mosque and recite a sermon in the name of the Abassid khalifa in Baghdad. No one protested and so the deed was done. The frail young khalifa soon expired of natural causes without learning that he was a private citizen and that his dynasty had ended. His death left Saladin as the sole ruler of Egypt.
