Слово о полку Игореве
The origin of the tales is unknown. The archetype may contain elements derived from the 12th-century pagan Cuman-Kipchak (Polovtsian) leader Khan Konchak, who is recorded in "The Tale of Igor's Campaign"; over time a balanced view of the non-Christian Cuman Khan may have been distorted or caricatured by Christian Slavic writers.
