That good idea LOL!
Don't forget he know how to welcome Baghdad into his empire LOL!
YES but is worth to remember that was his GRANDSON HULAGU KHAN
that took Baghdad....
Hulagu probably always intended to take Baghdad, which the Mongols had been meaning to attack for over ten years, but he used the caliph's refusal to send troops to him as a pretext for conquest, since his brother the Great Khan had ordered him to be merciful to those who submitted. Hulagu sent a message to the caliph, Al-Musta'sim, containing the following:
"When I lead my army against Baghdad in anger, whether you hide in heaven or in earth
I will bring you down from the spinning spheres;
I will toss you in the air like a lion.
I will leave no one alive in your realm;
I will burn your city, your land, your self.
If you wish to spare yourself and your venerable family, give heed to my advice with the ear of intelligence. If you do not, you will see what God has willed."
