The End of Imperial China
An accidental bomb explosion exposed a revolutionary plot, the garrison mutinied rather than face execution, and within four months two thousand years of imperial rule in China had ended — the last emperor was a five-year-old boy who abdicated in 1912. The republic that replaced it fractured almost immediately into warlord rule. The Mandate of Heaven had been lost many times before and always claimed by a new dynasty; this was the first time no one claimed it.
The story that justifies an order (divine right, mandate, ideology) loses credibility; the order it propped up follows.
