Byzantium became an object for study in the 19th century. Notably Fallmerayer and George Finlay dealt with the subject . By the 20th century it had become obvious that the history of Byzantium was significant, however Byzantine history has yet to find its place in contemporary historiographic debate. Today it is mostly the social history, and cultural history that are researched by historians, now that the distinction between disciplines has become more flexible. In every Byzantine historian’s work there lies implicitly one or another historiographic theory, such as 19th century positivism, a Marxist reading of history, the Marxist type school of Annales, the theory of structuralism that comes from the discipline of anthropology, and new-positivism.
