Archaeological evidence indicates that the history of Inuit clothing extends far back into prehistory, with significant evidence to indicate that the basic structure of Inuit clothing has changed little since. The clothing systems of all Arctic peoples (encompassing the Inuit, Iñupiat, and the indigenous peoples of Siberia and the Russian Far East) are similar, and evidence in the form of tools and carved figurines indicates that these systems may have originated in Siberia as early as 22,000 BCE, and in northern Canada and Greenland as early as 2500 BCE. Pieces of garments found at archaeological sites, dated to approximately 1000 to 1600 CE, are very similar to garments from the 17th to mid-20th centuries, which confirms consistency in the construction of Inuit clothing over centuries.
