A new study from researchers at the University of Wisconsin-Madison, in collaboration with scientists in Kazakhstan and Japan, provides fresh insights into the genetic makeup and cultural integration of the Mongol Empire. By analyzing DNA from the remains of Golden Horde ruling elites buried in Kazakhstan, the team found evidence of shared genomic fragments across Kazakhstan and Mongolia, indicating close genetic ties. However, the data also suggests the widespread belief that one in 200 men is directly related to Genghis Khan may be an oversimplification, as the specific genetic branch found in the elite tombs is less common in modern populations.

Why it matters

This research offers a more nuanced understanding of the genetic legacy of the Mongol Empire, moving beyond popular myths and providing archaeologists and geneticists new avenues to explore the complex interplay between the ruling class and local populations during the empire's expansion. The findings challenge previous assumptions and highlight the value of ancient DNA analysis in uncovering the true genetic history of major historical figures and empires.

The details

The study analyzed DNA from four tombs belonging to ruling elites of the Golden Horde, the northwestern extension of the Mongol Empire. One of the tombs is believed to belong to Joshi, the eldest son of Genghis Khan and founder of the Golden Horde. The researchers found evidence that the genomes of these individuals trace their ancestry back to the Mongolian plateau, with shared Y-chromosome markers in the C3* cluster. However, this specific genetic branch appears less common in modern populations than the broader C3* cluster, which has fueled the popular notion of widespread Genghis Khan ancestry.

  • The study's findings were recently published in the Proceedings of the National Academy of Sciences in February 2026.

What they’re saying

“Even though the medieval genetic landscape of Central Eurasia is already known thanks to previous studies, we believe this is the first ancient DNA evidence to support the genomic ancestry of ruling elites in the Golden Horde.”

— Ayken Askapuli, Lead author of the study (Proceedings of the National Academy of Sciences)

“With ancient DNA results, we can distinguish different branches of the genome that are close to each other but are not identical. The one that Askapuli has found in the Golden Horde ruling elites is a branch of the C3* cluster but it's not as common as the larger branch.”

— John Hawks, Co-author of the paper (Proceedings of the National Academy of Sciences)

What’s next

Researchers plan to continue this work, possibly using data from modern-day genomes and advanced techniques to better understand the region's genomic connections across time and further explore the genetic legacy of the Mongol Empire.

The takeaway

This study challenges popular myths about the widespread genetic legacy of Genghis Khan, providing a more nuanced understanding of the Mongol Empire's genetic and cultural integration with local populations. The findings highlight the value of ancient DNA analysis in uncovering the complex histories of major historical figures and empires.
