Everyone makes mistakes, but the scale and impact of one blunder or another is rarely similar. But some mistakes are so monumentally big that they can end large companies, devastated whole countries and even upset continent-wide ecosystems. So perhaps you tripping in public is not that bad, is it?

A governor of the Khwarazmian Empire killed a peaceful emissary from a neighboring empire, who had been sent to establish trade relations and political connections between the two powers. The emissary was sent by Genghis Khan. Genghis Khan replied by invading the Khwarazmian Empire, obliterating everything in his path, burning basically the entire thing to the ground, and then destroying any record of the Khwarazmian Empire that he could find. He finished all of this off by diverting the river that fed the country water, causing the land where the empire once stood to become a dry and barren wasteland. Possibly one of the biggest mess ups in history.
