Beneath Colorado’s Yucca House lies proof of a 800-year-old social experiment

Yucca House’s Failed Democratic Revolution Against Chacoan Rule

Around 1100, Yucca House began as just another town in the Chaco system that ruled the Four Corners. But by 1200, the people had other plans.

They tore down walls, built an open plaza, and did something bold – they shared power. This wasn’t just new floors and rooms.

It was a total rejection of the old way where elites called all shots. Sadly, their experiment ended in bloodshed.

By the 1270s, violence swept through the region, forcing thousands to flee south.

Today, Yucca House National Monument stands mostly unexcavated, holding secrets of this ancient democratic experiment beneath Colorado soil.

Chaco Bosses Built Yucca House as Their Regional Hub

Around 1100 CE, powerful leaders from Chaco Canyon set up Yucca House as one of their outposts in southwest Colorado.

The community had buildings dated from 1163-1263 and featured the big “great house” style that showed Chacoan control.

Built near a good spring, this town helped extend the political system that ran the Four Corners region for hundreds of years. Chaco bosses used places like this to spread their power and gather resources.

The Village Grew Into a Big Community

Yucca House got much bigger during its best years, growing to about 600 rooms, 100 kivas, several towers, and many plazas.

The West Complex formed a D-shaped pueblo built over the spring, with many room blocks and a great kiva for ceremonies. The Upper House had two enclosed kivas and special limestone block walls showing Chaco style.

The spring water let people grow corn, beans, squash, and yucca in this dry area.

Everything Changed When Chaco’s Power Fell Apart

The strong Chacoan system fell around 1150 CE, ending three hundred years of control and leaving communities like Yucca House on their own.

Towns across the Four Corners rushed to create new ways to run things without central leaders. People tried different social and political setups as they figured out what to do next.

Former Chaco outposts faced the challenge of making their own decisions after years of outside control.

The People Broke Down Walls of Power

Around 1200 CE, Yucca House folks started changing their town by opening up the community plaza. They took down or changed structures that once kept elite areas separate from common spaces.

The new layout looked very similar to other post-1200 villages like Sand Canyon Pueblo, hinting at a move away from rulers.

Adobe building showed up in the Upper House, an unusual method for this area that suggested new cultural links forming after Chaco’s fall.

A Social Revolution Started in the Plaza

Yucca House created a plaza unlike any other Mesa Verde village from that time. The community tried a complete reordering of their spiritual practices and social setup.

Power moved from elites to common people, with new focus on community wellbeing rather than control by the few.

Archaeologist Scott Ortman noted that the town looked like an early version of Tewa villages that later formed in northern New Mexico.

Civil War Broke Out Across the Ancient Southwest

Fighting spread through the region as ruling elites tried to keep their power while common people pushed for change. Climate problems and food shortages made conflicts worse as towns fought over shrinking resources.

Larger settlements put more stress on already strained lands as people grouped together for safety.

The evidence suggests these fights weren’t random but part of a complex struggle over how society should work after Chaco’s collapse.

Hunger Spread Through the Mesa Verde Region

The late 1200s brought bad drought and crop failures throughout the Mesa Verde area. Communities turned to hunting and gathering when farming failed, greatly changing how they got food.

Wild plants, including what archaeologists call starvation foods, became common in their diet. Social bonds broke down as hunger led to desperation, with signs of society falling apart at sites across the region.

Neighbors Fought Neighbors in Brutal Violence

Widespread fighting took over the entire Mesa Verde region in the 1270s. Early explorer Richard Wetherill found the remains of dozens of murdered people at Yucca House.

At nearby Castle Rock Pueblo, forty-one people died in a massacre with extreme injuries to their bodies. Sand Canyon Pueblo saw dozens of violent deaths, with some remains showing signs of possible cannibalism.

The violence seems to have hit every community in the region.

The Last Families Decided to Leave

Yucca House stayed lived in longer than many nearby communities, possibly because its new social structure helped it handle the crisis better than others.

The people finally saw their world was breaking beyond repair and chose to move south.

They likely knew about the Northern Rio Grande region through obsidian trading connections that had linked the regions for years. Their decision to leave seems planned rather than a panic.

Thousands Walked Away From Their Ancestral Homes

Between 1250-1290, about 35,000 people left the Mesa Verde region, heading south and west to new lands. The largest group, around 15,000 people, moved to the middle Rio Grande Valley in what is now New Mexico.

The entire region became mostly empty by 1290, just 30-40 years after reaching its highest population.

Tewa oral histories describe a “12-step” journey south covering 250 miles, likely a 12-day migration route to their new homeland.

The Yucca House Experiment Lives On in Tewa Culture

The people who left Yucca House became ancestors of today’s Tewa people in northern New Mexico. Turkey DNA evidence and skull measurements confirm biological connections between the regions.

Their experience at Yucca House showed that major societal change from hierarchical to more equal systems was possible through deliberate community action.

The social experiment at Yucca House represents one of the clearest examples of Indigenous peoples actively reshaping their political systems in response to changing conditions.

Visiting Yucca House National Monument, Colorado

Yucca House National Monument preserves ruins where Ancestral Puebloans rejected elite rule around 1200 CE, creating an open plaza that shared power among all community members.

You’ll reach the site via County Road B to County Road 20.5 near Towaoc, driving through private ranch property. There’s no entrance fee or visitor center.

Mesa Verde National Park manages it, and you can get your passport stamp there or at Hovenweep. Remember to close all gates behind you.
