Olga Kudrina

Olga Dmitrievna Kudrina (c. 1890-1944) was a shamaness among the Reindeer Evenki of northern Inner Mongolia along the Amur River's Great Bend (today under the jurisdiction of Genhe, Hulunbuir). She was accepted as an arbiter between the various Reindeer Evenki groups, helping to defuse conflicts between families when a member of one murdered a member of the other; after her death, the egalitarian hunters were left with no widely accepted shaman or other authority figure, and conflicts among them escalated into a chain of serious cases of blood revenge.
