Siberian Cossacks were Cossacks who settled in the Siberian region of Russia from the end of the 16th century, following Yermak Timofeyevich's conquest of Siberia. In early periods, practically the whole Russian population in Siberia, especially the serving-men, were called Cossacks, but only in the loose sense of being neither land-owners nor peasants. Most of these people came from northwest Russia and had little connection to the Don Cossacks or Zaporozhian Cossacks.
