This paper presents the computer and other methods and sources used to map the ethnic history of the Khanty and Mansi. Since their remote location and history is not well known, I need first to present an introductory overview. This is based on my articles on the Khanty and Mansi ethnohistory as well as my dissertation 'Politica russkogo pravitelstva v otnoshenii yasachnogo naseleniay severa zapadnoi Sibiri v 17 v.' [Russian state politics towards the indigenous peoples of the Northwestern Siberia in the 17th century] (1992) and book (forthcoming Zoos) 'Religioznye traditcii Khantov vXVII-XXvv.' [Religious traditions among the Khanty. 17(th)-20(th) centuries]. Three sample maps are attached, more will be presented during the conference.
