To my knowledge, the Mari people were able to maintain their native faith in a relatively unbroken form through to the present day, despite pressures from Christianity. Can anyone tell me what their religious situation was like during the early-modern period (1500-1750)? Also, were there any other European groups during this period that still maintained their indigenous religions without having been assimilated into the Abrahamic faiths? I am not sure, for instance, what the religious situation of the Sami, Komi, or Udmurt was during the early-modern period?
