The Selk'nam were an indigenous people who lived in the southern part of South America, particularly in Tierra del Fuego. They were known for their unique culture, which included traditional ceremonies, hunting practices, and a deep connection to the land. The Selk'nam primarily relied on hunting and gathering for their sustenance, with a focus on animals like seals and birds. In the late 19th and early 20th centuries, the Selk'nam faced significant challenges due to colonization and the expansion of sheep farming in their territory. This led to a dramatic decline in their population and culture, as many were displaced or died from disease and violence. Today, efforts are being made to preserve their heritage and raise awareness about their history.
