Researchers have peered again by way of 800 years of historical past to conclude that Mayapan – the capital of tradition and politics for the Maya folks of the Yucatán Peninsula within the 13th and 14th century CE – could effectively have been undone by drought.


That drought would have led to civil battle, which might, in flip, have caused political collapse, in keeping with the researchers.

Folks would then have retreated to smaller and safer settlements.

In addition to giving us a helpful perception into the historical past of this historical folks, the brand new examine is a warning as effectively: about how shifts in local weather can shortly put pressures on even essentially the most well-established and affluent civilizations.

“A number of knowledge sources point out that civil battle elevated considerably, and generalized linear modeling correlates strife within the metropolis with drought situations between 1400 and 1450 CE,” write the researchers of their printed paper.

“We argue that extended drought escalated rival factional tensions, however subsequent diversifications reveal region-scale resiliency, making certain that Maya political and financial buildings endured till European contact within the early 16th century CE.”

The group already had lots of historic information to work with, overlaying inhabitants change, modern diets, and local weather situations.

These information had been augmented with a brand new evaluation of human stays for indicators of traumatic damage (pointing to battle).

Correlations emerged between elevated rainfall and an elevated inhabitants within the space, and between subsequent decreases in rainfall and elevated battle. Extended drought throughout 1400-1450 CE almost certainly led to the abandonment of Mayapan, the researchers say.


The shortage of water would have affected agricultural practices and commerce routes, placing pressure on the folks of Mayapan, the examine suggests. As meals acquired scarcer and the scenario acquired extra harmful, folks both died or dispersed.

Within the closing mass grave dug earlier than the town was deserted, the researchers report that most of the stays in all probability belonged to the members of the family of the Cocoms (the heads of state) – a bloody finish introduced on by competing factions and social unrest.

“Our findings help Mayapan’s storied institutional collapse between 1441 and 1461 CE, a consequence of civil battle pushed by political rivalry and ambition, which was embedded within the social reminiscence of Yucatecan peoples whose testimonies entered the written report of the early Colonial Interval,” write the researchers.

Human responses to environmental pressures corresponding to drought are clearly complicated, various by area and by period – there are such a lot of components to weigh up and steadiness in terms of contemplating why a historic inhabitants acted in the best way that it did.

The motion of individuals to different elements of the Yucatán Peninsula, together with affluent coastal cities and politically unbiased settlements, helped the Maya tradition proceed to thrive after the autumn of Mayapan – and there was little proof of any battle between these areas earlier than Spanish rule began.


That is testomony to a “resilient system of human-environmental diversifications,” the researchers say, however diversifications can solely get you to date. These identical areas, together with the remainder of the world, are as soon as once more dealing with as much as a local weather disaster.

“Archaeological and historic information are effectively fitted to analyzing previous societal results of local weather crises over long-term cycles,” write the researchers.

“The Maya area gives the breadth and depth of archaeological, historic, and local weather information important for finding out correlations between social change and fluctuating local weather situations.”

The analysis has been printed in Nature Communications.
