Is this the most important one hour in human history?

This may not necessarily qualify as the most important one hour in human history, but it is significant in terms of the enormity of the events that purportedly happened in one hour.

Genghis Khan is the founder and first emperor of the Mongol empire whose armies devastated and subjugated much of Asia and parts of Europe in the late 12th, and early 13th centuries.It is believed that he Genghis Killed 1,748,000 People at Nishapur in One Hour.

Legend has it that during an invasion of a city in Persia (present day Iran), his favorite son-in-law was killed by an arrow shot by one of the city’s inhabitants. Embittered and enraged by her husband’s death, Genghis Khan’s daughter requested for a revenge attack on the city, ordering the complete massacre of all it’s dwellers. Men and women were murdered, decapitated even, as added measure in response to Genghis Khan’s daughter’s skepticism about the fatality of the attacks. It has been reported that over a million people lost their lives in this attack that supposedly happened in a period of one hour.

While there are conflicting reports about the actual number of deaths, the numbers are still staggering given the military systems and strategies that existed at the time; the ‘logistical’ factors that must be considered to effect a mass murder on such scale.
