Scientists Have Discovered Genghis Khan’s Secret Weapon

In 2010, two scientists researching wildfires in Mongolia’s Khangai Mountains stumbled upon the secret that led to the largest connected land empire in history: the Mongolian Empire.

The cornerstone of that discovery was several Siberian Pine trees growing out of cracks in an 8,000 year old bed of cooled lava. In such dry and low-soil conditions, these trees grow very slowly. Some were over 1,100 years old.

Parts of 107 trees — cross sections of the trunks of dead trees and cores of live ones — showed that this area had experienced unusually mild temperatures and abundant rain while Genghis Kahn was building his empire.

This lucky streak of weather acted like a secret weapon literally fueling his army — and is likely what allowed him to take over much of Asia.

Ancient weather

The researchers were able to recreate the weather by analyzing the width of the tree rings. Fatter rings represent years that were wetter. The ancient trees in this lava patch let the team construct a climate timeline of the last 1,112 years.

Out of over 1000 years of data, 15 stood out as having unprecedented rainfall and mild weather. Those years coincide almost exactly with the rise of Genghis Khan and the Mongolian Empire.

“Unusual moisture creates unusual plant productivity,” study researcher Amy Hessl, from West Virginia University, said in a press release. And in an empire that lived on roving livestock, where each Mongol warrior was rumored to have at least five horses, plant productivity literally created more horsepower.

“Before fossil fuels, grass and ingenuity were the fuels for the Mongols and the cultures around them,” study researcher Neil Pederson, of Colombia University said in the release.

“I sort of think of it as nature set the table and Genghis Khan came to eat. He didn’t have to come to eat and he didn’t have to eat the way he did, but the table was set,” said Hesssl in avideo.

The creation of an empire

Once climate set the table, the rest was up to the Mongol’s political know-how, technological prowess, and brilliant use of cavalry, said the release. In the GIF below, the red shows the growth of the Mongol Empire. By the late 1200′s, the Mongol empire had split into four “states” — one for each of his official sons — shown in yellow, light green, dark green, and purple.

The tree data also showed a drought in the preceding and early “turbulent” years of Khan’s rule. The years between 1180 to 1190 A.D. were very dry and “characterized by warring tribes and factions on the Mongolian steppe,” the authors wrote in the study, published March 10, 2014 in the journal Proceedings of The National Academy of Sciences.

The Mongols weren’t the only empire impacted by climate. Previous studies have linked the fall of empires with deteriorating climatic conditions, including the old Angkor Empire in Cambodia. But, few studies have explored how favorable climate creates empires.

However, “we live in a sea of coincidence — something like that is hard to prove,” paleoclimatologist David Stahle of the University of Arkansas, who was not in involved in the study, said in the press release. He does add that in this case, the researchers make a convincing argument, and “they’ve provided an incredibly important climate record,” he said.
