After the war, Nikos Svoronos emerged as an innovator of historiography with a Marxist approach but beyond the narrow party boundaries. In the entirety of his work but especially in "Review of the modern Greek history" (1953/1976) he tried to understand the Greek history holistically, as an ethnic continuum that identifies with the "rebel" character of the Greeks. His struggle was equally divided between the nationalist exploitation and the Marxist rejections. As a historian, he placed the source of contemporary Hellenism and its path to national independence in Byzantium and the 400 years of Ottoman occupation.
