The Tuvans or Tuvinians are a Turkic people ethnic group living in southern Siberia. They are historically known as one of the Uriankhai, from the Mongolian designation. Tuvans have historically been cattle-herding nomads, tending to their herds of goats, sheep, camels, reindeer, cattle and yaks for the past thousands of years. They have traditionally lived in yurts covered by felt or chums covered with birch bark or hide that they relocate seasonally as they move to newer pastures. Traditionally, the Tuvans were divided into nine regions called khoshuun, namely the Tozhu, Salchak, Oyunnar, Khemchik, Khaasuut, Shalyk, Nibazy, Daavan & Choodu, and Beezi. The first four were ruled by Uriankhai Mongol princes, while the rest were administered by Borjigin Mongol princes.
