The encouragement and evolution of the culture of the Republic of Macedonia has had a far greater and more permanent impact on Macedonian nationalism than has any other aspect of Yugoslav policy. While development of national music, films and the graphic arts has been encouraged in the Republic of Macedonia, the greatest cultural effect has come from the codification of the Macedonian language and literature, the new Macedonian national interpretation of history and the establishment of a Macedonian Orthodox Church in 1967 by Central Committee of the Communist Party of Macedonia.
