Question

what was the most significant cause of the ilkhanates collapse? (1 point)
the ilkhanate collapsed because the ruler did not have a male heir.
the ilkhanate collapsed because of the its support of sufism.
the ilkhanate collapsed because of internal revolts by the han chinese.
the ilkhanate collapsed because it was devastated by the bubonic plague.

Explanation:

The Ilkhanate faced multiple challenges, but the bubonic plague (Black Death) had a catastrophic impact on its population, economy, and social fabric. It disrupted trade, weakened military strength, and led to widespread social unrest. While other factors like succession issues (not having a male heir) and internal strife existed, the plague's scale and far - reaching consequences were most significant. The support of Sufism was more of a cultural aspect and not a collapse - causing factor. The Han Chinese revolts were more relevant to the Yuan dynasty (not the Ilkhanate).

Answer:

The Ilkhanate collapsed because it was devastated by the bubonic plague.
