History

In April 2015, looters sacked an ancient cave burial at a site called Urd Ulaan Uneet high within the Altai Mountains of western Mongolia. When police apprehended the criminals, they uncovered, among other artifacts, an elegantly carved saddle made from several pieces of birch wood.

Now, in a new study, researchers from Mongolia collaborating with University of Colorado Boulder archaeologist William Taylor have described the find. The team’s radiocarbon dating pins the artifact to roughly around the year 420 AD, making it one of the earliest known frame saddles in the world.

“It was a watershed moment in the technological history of people and horses,” said Taylor, corresponding author of the new study and curator of archaeology at the CU Museum of Natural History.

He and his colleagues, including scientists from 10 countries, published their findings last month in the journal Antiquity. The research reveals the underappreciated role that ancient Mongolians played in the spread of horse-riding technology and culture around the globe. Those advances ushered in a new and sometimes brutal era of mounted warfare around the same time as the fall of the Roman Empire.

The discovery also highlights the deep relationships between human and animals in Mongolia. For millennia, pastoral peoples have travelled between the vast grasslands of the Mongolian Steppe with their horses—which, in the region, tend to be short but sturdy, capable of surviving winter temperatures that can plummet far below freezing. Airag, a lightly alcoholic beverage made from fermented horse milk, remains a popular libation in Mongolia.

“Ultimately, technology emerging from Mongolia has, through a domino effect, ended up shaping the horse culture that we have in America today, especially our traditions of saddlery and stirrups,” Taylor said.

But these insights also come at a time when Mongolia’s horse culture is beginning to disappear, said study lead author Jamsranjav Bayarsaikhan. “Horses have not only influenced the history of the region but also left a deep mark on the art and worldview of the Nomadic Mongols,” notes Bayarsaikhan, an archaeologist at the Max Planck Institute for the Science of Human History in Germany. “However, the age of technology is slowly erasing the culture and use of horses. Instead of herders riding horses, more and more people are riding motorcycles in the plains of Mongolia.”

Mounted combat

Bayarsaikhan was working as a curator at the National Museum of Mongolia when he and his colleagues got a call from police in Hovd Province. The team later excavated the Urd Ulaan Uneet cave and unearthed the mummified remains of a horse, which the group partially described in a 2018 paper.

The saddle itself was made from about six pieces of birch wood held together with wooden nails. It bears traces of red paint with black trim and includes two leather straps that likely once supported stirrups. (The researchers also reported an iron stirrup recently discovered from around the same time period in northern Mongolia).

The group couldn’t definitively trace back where those materials came from. Birch trees, however, grow commonly in the Mongolian Altai, suggesting that locals had crafted the saddle themselves, not traded for it.

Taylor explained that humans had used pads, a form of proto-saddle, to keep their rear ends comfortable on horseback since the earliest days of mounted riding. Rigid wooden saddles, which were much sturdier, paired with stirrups opened a new range of things that people could do with horses. “One thing they very gave rise to was heavy cavalry and high-impact combat on horseback,” Taylor adds. “Think of jousting in Medieval Europe.”

The researchers also note that evidence from this saddle and other finds assisted the peoples of the Steppe in warfare. They write:

These improvements to equestrianism, and by inference to equestrian combat, may have contributed to the formation of early steppe polities. In addition to facilitating mounting while encumbered, stirrups gave stability to the rider’s seat and freedom of movement for the upper body, meaning that they could be more effective in shock combat—sustaining and delivering heavy ‘hacking’ blows while mounted, using lances, swords, spears and other heavy weaponry. The stirrup also enabled riders to stand in their seat, making it more secure to trot, a gait that can jostle a stirrup-less rider. So equipped, steppe riders could ride to battle with heavier armour or weapons, or use existing weapons in new ways, giving early adopters an advantage in horse combat and transport.

Travelling west

In the centuries after the Mongolian saddle was crafted, these types of tools spread rapidly west across Asia and into the early Islamic world. There, cavalry forces became key to conquest and trade across large portions of the Mediterranean region and northern Africa.

Where it all began, however, is less clear. Archaeologists have typically considered modern-day China the birthplace of the first frame saddles and stirrups—with some finds dating back to the fifth to sixth century AD or even earlier.

The new study, however, complicates that picture, Taylor said. “It’s not the only piece of information suggesting that Mongolia might have been either among the very first adopters of these new technologies—or could, in fact, be the place where they were first innovated,” he said.

He suspects that Mongolia’s place in that history may have gone underappreciated for so long in part because of the region’s geography. The population density in the country’s mountainous expanses is low, among the lowest on Earth, making it difficult to encounter and analyze important archaeological finds.

Bayarsaikhan, for his part, calls for more archaeological research in the nation to better tell the story of horses in Mongolia. “Mongolia is one of the few nations that has preserved horse culture from ancient times to the present day,” he said. “But the scientific understanding of the origin of this culture is still incomplete.”
