The article focuses on one of the understudied aspects of the study of local history in Ukraine in the modern era, namely in the “long” nineteenth century – on the mode of reflection in historiographical images of the history of various Ukrainian regions and other loci the role of individual ethnic groups and their historically related states, in particular the Polish one. The analyze was made with using the concept of the “long” nineteenth century and the concept of metatext borrowed from literary practice. The objectives of the study included identifying the differences and common features in the coverage of Polish aspects in historical works, depending on the exploring locus, determining the existence of certain metatexts, finding out whether there were cases of creating works on the history of Ukrainian regions that would integrate elements of Polish themes on the basis of a non-evaluative, “objective” approach, or would provide positive assessments of the role of Poles in certain local history. As a result of the study, it was determined that the Polish component is reflected in historiographical interpretations of the history of different regions and smaller loci, not only of those that were at the end of the eighteenth century the part of the Polish-Lithuanian Commonwealth. Circumstances of the development of regional historiography in the nineteenth century led to the coexistence in specific studies of different concepts and approaches. Interpretations of the Polish component in the history of regions and smaller have local specifics and can be regarded as representations of several metatexts with pronounced characteristics.
