Derived from Slavic tribes in the 7th to 9th century.jpg: Jirka.h23, which was based on: Jaroslav Šlajer, Václav Tyr, Alois Sosík, Emil Stračár, Vojtěch Vrabec, Václav Žáček Dějiny středověku a novověku, učební text pro 7. postupný ročník. (Praha 1960), str. 9. Státní pedagogické nakladatelství. (History of the Middle Ages and the Modern Age, a textbook for the 7th consecutive year. (Prague 1960), p. 9. State Pedagogical Publishing House.") This is a slightly altered .svg version of the same map by Jirka.h23. Instead of using stripes to show areas of lower Slavic population it uses lower opacity tones.
