The Thule culture refers to a prehistoric Inuit culture that developed around 1000 AD in the Arctic regions of North America, particularly in areas like Alaska and Greenland. The Thule people are known for their advanced hunting techniques, using tools made from materials such as bone, ivory, and stone. They primarily hunted marine mammals, including whales, seals, and walrus, which were crucial for their survival. Thule culture is characterized by its distinctive semi-subterranean houses, often built from whale bones and covered with earth. This culture is considered a precursor to modern Inuit societies and played a significant role in the adaptation of people to the harsh Arctic environment. The Thule people also developed complex social structures and trade networks, influencing later indigenous cultures in the region.
