We constructed a questionnaire on the key aspects of Christianization and of the changes in power-structures: the responses for each country follow the same order under the same headings, so the material can be easily compared. You can search this site either by regions or by topics. Attached to the responses, you will also find lists of the relevant primary and secondary sources (bibliographies) as well as images.
We completed the collection and analysis of the material in 2004 and do not plan to update the website. See also our book: Nora Berend, ed. Christianization and the Rise of Christian Monarchy: Scandinavia, Central Europe and Rus' c. 900-1200 (Cambridge: Cambridge University Press, 2007).
