Question

Collapsed because of its support our stuff is on
Co-ops, because the religion not have a mail air
Collapse because of internal revolts by the Han Chinese

Answer 1

The most significant cause of the Ilkhanates' collapse was internal revolts by the Han Chinese. These revolts weakened the Ilkhanates and their control over the region, ultimately leading to their downfall. The devastation caused by the bubonic plague also played a role in the decline, but it was not the primary cause. Support or lack thereof from co-ops and religion was not a significant factor in the collapse of the Ilkhanates.
