6. Emperor Yang of Sui (China)
Emperor Yang of Sui (569-618) is renowned for his extravagant construction projects, including the Grand Canal and numerous palaces, which drained the state’s resources. To fund these endeavors, he imposed heavy taxes on the populace. The forced labor and financial burdens led to widespread discontent, culminating in revolts and the swift collapse of the Sui dynasty. His reign exemplifies the perils of prioritizing personal luxury over effective governance.
