The purpose of this thesis is to provide an overview and analysis of the influence of the communist ideologies on the archival appraisal in Yugoslavia from 1945 to 1991, long with the current state of the archival records in Republic of Croatia in that context. The ideologization of archive appraisal is closely related to the Hans Booms' criticism of the Marxism-Leninism influence on appraisal. Booms' criticism of the archival systems in East Germany is based on the notion that the archival science influenced by the already mentioned ideology is far superior to the rest of the archival approaches in archival theory and practice. He particularly gives attention to the appraisal, as it is one of the key processes in the archival practice. From the historical point of view, archival appraisal was often based on subjectivity of the archivists and a personal understanding of value, so it was significantly easier for the archivists in East Germany to ideologize the whole process. Yugoslavia, as a country in which the political ideology existed, can be used as a good example of both positive and negative characteristics of this approach to appraisal. With analysis and understanding of the prevailing archival system in Yugoslavia, it is possible to identify its influence on the current state and amount of archival records in Croatia.
