Tribal rugs were or are presumably made by people in a tribal social organization, very likely nomads dwelling in tents, moving from place to place with the herds of sheep and goats that provided the wool for the rugs.
This Navajo is a small piece, with a utilitarian purpose. Navajos are textiles produced by Navajo people of the Four Corners area of the United States. Navajo textiles are highly regarded and have been sought after as trade items for over 150 years. Navajo textiles were originally utilitarian blankets for use as cloaks, dresses, saddle blankets, and similar purposes. Hand-spun wool from sheep animals was the main source of yarn for Navajo blankets until the 1860s.
