Invasions barbares
Dahn's writings were influential in the conception of the European Migration Period ("Völkerwanderung" ) in German historiography of the late 19th and early 20th centuries. His multi-volume "Prehistory of the Germanic and Roman Peoples", a chronology of the Migration Period that first appeared in print in 1883, was so definitive that abbreviated versions were reprinted until the late 1970s.
