Tamburlaine's sons and grandsons opened the era of Turkish Renaissance in the fields of art, culture and literature.
Tamburlaine had only 4 sons and 2 daughters from his 9 wives. However, when he died, two of his sons were alive. Of these two sons, Mihrishah was in Arabian Iraq (Baghdad) and Azerbaijan as the bey of these regions. The other son of him called as Shahruh administered Khorasan in the name of his father.
Tamburlaine had selected his grandson, Pir Muhammed Mirza as the crown prince in his testament. Pir Muhammed was the younger son of his son, Cihangir Mirza. However, when Tamburlaine died in Otrar while he was on the way for an expedition to China, Pir Muhammed was governing India and Afghanistan in the name of his grandfather. It would take much time to come from those regions for the enthronement and to become the leader of the army. Furthermore, those who would benefit his departure from that region in order to become the Great Khan could cause civil turmoil. On the other hand, the vacancy in the throne of the khanate for a long time would probably cause the struggles for the throne as it was observed in the other periods of the history. Moreover, the resolution was to be taken whether the army would continue the military expedition to China.
Tamburlaine must have absolutely thought of these dangers. However, pursuant to his arrangement of his testament, he hoped that he would live long enough to take some precautions against these dangers.
The commanders that evaluated the conditions declared Miranshah's son, Sultan Halil Mirza as the Khan.
Halil Mirza was only 21 years old and he did not have the proper experience in order to govern the greatest empire of the world. His paternal uncle, Shahruh did not approve his enthronement as the Khan. Halil Mirza who was an emotional poet that wrote poems in Turkish and Farsi languages committed suicide upon the preference of his other brothers in the favour of Shahruh and declaration of the khanate of Shahruh.
