Ahmed Tekuder (Mongolian: Tögöldör/Төгөлдөр, meaning “perfect”), also known as Sultan Ahmad (reigned 1282–1284), was the sultan of the Persian-based Ilkhanate, son of Hulegu and brother of Abaqa. He was eventually succeeded by his nephew Arghun Khan.
Tekuder was born Nikola (Nicholas) Tekuder Khan, and was baptized in his childhood as a Nestorian Christian. However, Tekuder later converted to Islam and changed his name to Ahmed.
When Tekuder assumed the throne in 1282, he turned the Ilkhanate into a sultanate. Tekuder zealously propagated his new faith and sternly required his ranking officers to do the same. However, his nephew Arghun, the governor of Khorasan, was a Buddhist; and asked Kublai Khan, the Great Khan of the Mongol Empire and the emperor of the Yuan Dynasty, for help. Although, Kublai was angry with the situation, Arghun had to overthrow Tekuder himself given that the Great Khan's empire was far away from Persia.
Tekuder sent a friendly letter to the Mamluk sultan and wished for peace. His conversion to Islam and good ties with the Mamluks were not viewed well by Mongol nobles.
Transcend unto this mind all the knowledge of your dreams
How can it be both inside the same dream?
How can it be How can we be in the same dream?
How much more can we change
These buildings are shifting, this glass is rippling
The water is above us, yet it will not fall
Why is it all out of focus
I thought this was perfect now I see its flaws
Step by step, brick by brick
I will turn this world into what I see fit
I can be anything, I will become everything
Captivated by the sounds of the lost souls
Their voices are ever-haunting
Who are these faces? Why do they stare at me?
Look away, look away
Why is this crumbling at my face
How much more can we change
These buildings are shifting, this glass is rippling
The water is above us, yet it will not fall
Why is it all out of focus
I thought this was perfect now I see its flaws
I open my eyes to the world and everything changes
Now everything's perfect (Now I see its flaws)
