The Thule Culture: Ancestors of Modern Eskimos

Key Insight

The Thule, a vigorous and highly skilled whale-hunting culture, emerged from the Old Bering Sea culture and became ascendant during a climatic optimum between 900 and 1100 AD. This warming trend, involving an increase of merely 3°F, dramatically shifted the Arctic ecosystem northward, allowing bowhead whale populations to meet in Parry Channel and other sea mammals to penetrate farther north. This climatic window facilitated the rapid eastward expansion of the Thule, covering 2600 miles from Point Barrow to Peary Land in just two or three generations.

The Thule possessed an elaborate marine-mammal hunting technology, utilizing umiaks for whale and walrus hunts, kayaks, and sophisticated harpoons, advancements beyond their Dorset predecessors. They developed the dog-drawn sled and constructed warm, semi-subterranean winter homes with stone walls, turf roofs supported by whale bones. Their success was profound, comparable to the Magdalenian caribou-hunting culture in Europe, reflecting a powerful confidence born from their capacity to thrive in their specific environment.

Directly ancestral to modern Eskimos, the Thule exemplified a sophisticated hunting culture that remained ecologically viable in the Far North long after farming supplanted hunting in Europe. However, the cooling trend that led to the Little Ice Age (1650-1850) caused the Thule culture to fragment into distinct traditions like the Polar, Central, and Caribou Eskimos. This forced adaptation meant their hunting tools and methods had to be altered or abandoned for survival, leading to a transitional period when Europeans encountered them, often misjudging their culture as backward due to a lack of understanding of these environmental necessities.
