Paparrigopoulos, as well as Sp. Zampelios, set the basis of the modern Greek historiography and influenced the modern Greek society. Since, their work did not concern only a closed and restricted circle of specialists and academics. It was addressed to the society of their times, in order to strengthen their national self-knowledge. Paparrigopoulos' classes at the University, which constituted the raw material for the writing of his memorable History, were frequently published in Pandora magazine, of which he was the co-publisher, as well as in the Athenian Press. The term Greek-Christian which was devised for scientific purposes, functioned towards the same direction but did not remain a simple instrument of analysis in the hands of specialists. As this term appeared in early ninth century, it became a canvass on which the ideology of the Greek state was developed and shaped. The content of education, the orientation of historical studies and the study of tradition (folklore) were organized on this basis. In addition, the Megali Idea (Greek Great Idea) which was nebulous until that time, acquired flesh and bones. The Byzantine Empire, which had now been acclaimed a cultural mold of the Greek state which was still small, became the model for its territorial expansion.
