 While the development of national music, films and graphic arts had been encouraged in the Republic of Macedonia, the greatest cultural effect came from the codification of the Macedonian language and literature, the new Macedonian national interpretation of history and the establishment of a Macedonian Orthodox Church.Meanwhile, the Yugoslav historiography borrowed certain parts of the histories of its neighboring states in order to construct the Macedonian identity, having reached not only the times of medieval Bulgaria, but even as far back as Alexander the Great.In 1969, the first "History of the Macedonian nation" was published.
