Civilization #5: The Yamnaya Conquest of Europe

• The episode explains how Europe transformed from an egalitarian, peaceful, goddess-worshipping farming society into a patriarchal, warlike civilization through the conquest of the Yamnaya, a nomadic pastoral people from the Pontic-Caspian steppe (modern-day Ukraine), roughly 5,000–6,000 years ago.
  • This builds on the previous class’s discussion of archaeologist Marija Gimbutas’s theory that “Old Europe” was a matrifocal, harmonious culture that was overthrown by warlike invaders.
  • The episode answers three questions: who the Yamnaya were, where they came from, and how they conquered Europe.

The World Before the Yamnaya

• After the last Ice Age ended (~12,000 years ago), agriculture was invented in the Near East (modern Turkey, Jordan, Syria, Israel), enabled by a warmer climate.
  • Farming was tied to religion: it allowed people to celebrate their spiritual beliefs through settled life.
• Around 8,000 years ago, a short cooling period pushed Near Eastern farmers to migrate into Europe.
  • Europe’s geography was similar enough to the Near East that they could transplant their religion, technology, and way of life with little change.
• These early Europeans and Near Easterners shared a common religious worldview, also found among many indigenous peoples worldwide (Africa, Australia, the Amazon):
  • Worship of a mother goddess who gives life to all things.
  • Belief in unity: all humans, animals, and plants are the same, all children of the mother goddess.
  • Responsibility to protect nature, not destroy it.
  • Belief in balance, harmony, and the survival of the soul after death.
• This religion produced an egalitarian society:
  • No significant distinction between men and women; women were often considered superior because they give life.
  • Governance was largely in the hands of women.
  • Peaceful, because resources were sufficient.
  • Intellectual energy went into art celebrating the mother goddess.

Social Evolution on the Steppe

• The steppe is a vast grassland stretching from Europe to Mongolia (called “tan” in Chinese).
  • Grassland cannot support crop farming, and humans cannot eat grass, so survival was much harder than in the Near East or Europe.
• The people of the steppe underwent a process the episode calls social evolution: open, cooperative competition.
  • Open: no central authority or hegemon; many independent groups competing.
  • Cooperative: groups still traded, communicated, exchanged wives and gifts.
  • This structure has been the greatest source of human innovation and creativity.
• The episode compares this to three historical periods with similar structures:
  • The Warring States period in China (source of Confucius, Laozi, and most Chinese intellectual breakthroughs).
  • The Greek city-states (Athens, Sparta, Thebes), which were eventually conquered by the Macedonians—outsiders who adopted Greek military innovations and then used them to conquer Greece, Persia, and Egypt under Alexander the Great.
  • The Sumerian city-states, which were conquered by the neighboring Akkadians under Sargon the Great, who built the world’s first empire.
• Two key principles of social evolution:
  1. Open, cooperative competition produces tremendous innovation.
  2. The group that ultimately triumphs is the one most ruthlessly willing to adopt all innovations for the purpose of destroying others and becoming the new hegemon.
• The Yamnaya were the group that did exactly this on the steppe.

The Yamnaya Innovations

• The Yamnaya developed several transformative innovations that gave them decisive advantages:

  • Pastoral economy: raising cattle, goats, and sheep.
    • Humans cannot eat grass, but livestock can; the Yamnaya raised animals originally obtained from farmers and grazed them on the steppe.
  • Dairy consumption (lactose tolerance).
    • Most humans are lactose intolerant; the Yamnaya developed the ability to drink milk.
    • Combined with meat protein, this made them dramatically larger and stronger: on average 20 cm taller than Near Eastern and European farmers, who ate mostly vegetables and had no dairy.
  • Domestication of the horse.
    • Horses are hardwired to flee humans; domestication took an estimated 3,000 years.
    • Horses allowed rapid movement across the vast steppe for trade, communication, and warfare.
  • The wheel and the wagon.
    • Combined with horses, wagons enabled a fully nomadic pastoral lifestyle: herds eat grass in one area, then the group moves on.
    • This mobility was the foundation of the nomadic pastoral economy.

How the Innovations Transformed Society and Religion

• Mobility created conflict over grazing rights and cattle theft, making violence central to steppe life.

  • Men became more important than women because they fought the wars.
  • This reversed the gender hierarchy of Old Europe.

• Private property emerged as a core concept.

  • Cattle were private wealth belonging to individuals, not to the community or the mother goddess.
  • This was entirely foreign to European farmers.

• Patriarchy followed from private property.

  • Men controlled wealth and society.

• Primogeniture (eldest son inherits everything) solved the inheritance problem.

  • If a father had 100 cattle and 10 sons, dividing the wealth would impoverish everyone within generations.
  • The eldest son inherited everything; the other sons had to go out and build their own wealth—typically by stealing cattle and conquering others.
  • This created a permanent war culture that celebrated young men expanding through violence.

• Religion shifted to match the new economy and society:

  • The mother goddess was replaced by a sky father (the Greeks later called him Zeus, the Romans Jupiter)—a male god of war and wealth.
  • Instead of nature being a gift to protect, cows, cattle, and wealth were the gifts of the sky father.
  • Instead of loving and protecting one another, people were now asked to fight each other for the right to have wealth.
  • Religion, society, and economy became fully aligned around war, wealth accumulation, and expansion.

How the Yamnaya Conquered Europe

• Europe had a major advantage: larger population, because farming supports denser settlement.

  • In theory, Europe should have been able to resist the Yamnaya.

• Three factors destroyed Europe’s ability to resist:

  1. The plague (identified as the bubonic plague, spread by rats).

     • The plague was present across Europe, the Near East, and the steppe because all these regions were in trading contact.
     • It devastated Europe far more than the steppe because European farmers lived in dense, settled communities (sometimes 10,000 people on a farm) alongside pigs, rats, and garbage—ideal conditions for disease transmission.
     • The Yamnaya, being nomadic and mobile, lived far apart, had more hygienic lifestyles, were physically stronger from dairy and exercise, and were less likely to catch and die from the disease.
     • The episode compares this to how European diseases killed most of the indigenous population of the Americas.
     • The plague was the single most important factor in destroying Old Europe.

  2. Climate change (a mini ice age ~5,000–6,000 years ago).

     • Bad for European farmers (crops failed) and for steppe herders (some animals died), but worse for farmers.
     • The cooling also pushed steppe peoples to expand further into Europe seeking new land.

  3. Yamnaya colonization and violence.

     • Young Yamnaya men with no wealth or wives invaded European villages.
     • They killed the local men and took the women as wives.
     • In some cases they offered to let the men go if they surrendered the women; the men would return with neighbors, leading to cycles of violence.
     • Eventually the Yamnaya conquered all of Europe, including England.

• The Yamnaya also conquered India, Iran, and Mongolia, but not China:

  • The Himalayas blocked horse-based armies from crossing into China.
  • China’s enormous population could have repelled an invasion.
  • China remained isolated from this world-system for most of its history.

The Result: A New World

• The Yamnaya conquest created a vast zone stretching from Europe to India with:
  • A common language: Proto-Indo-European.
  • A common religion: sky father worship.
  • Constant communication, trade, and exchange of ideas, people, and gods.
• This zone is what we today call the West, distinct from isolated China.
• The Mongolians are also descended from the Yamnaya; Genghis Khan later used very similar conquest strategies.
• The conquest was not a single event but a slow process over hundreds of years:
  • Different Yamnaya groups adapted to local geographies (e.g., initially tried to burn forests in Norway to recreate the steppe, then gave up and adopted agriculture).
  • They stole local technologies they lacked, such as shipbuilding, which allowed them to reach England.
• The three responses of European farmers were: fight (and be killed), cooperate, or flee (some island populations like Sardinia survived with less Yamnaya DNA).
• Essentially all Europeans today are descended from the Yamnaya, as are Indians and Iranians.
• This conquest marks a turning point in human history:
  • Before the Yamnaya: egalitarianism, peace, art, goddess worship.
  • After the Yamnaya: patriarchy, war, money, private property, sky father religion.
  • All subsequent Western civilizations—Greeks, Romans, and beyond—emerged from this Yamnaya-created world.
