Остерське староство у другій половині ХVI - на початку ХVII ст.: формування системи земельних володінь

The purpose of the research is to reveal the process of formation of the system of land holdings in the starostvo of Oster in the second half of the sixteenth - early seventeenth centuries. The research methodology was based on the use of problem-chronological, historicalgenetic, historical-comparative and logical-theoretical methods. The problem-chronological method involves the systematization of facts in chronological order, which allows us to reconstruct historical events in the light of causation. The historical-genetic approach has allowed us to highlight the regional specificity of the formation of the system of land tenure in the starostvo of Oster. The use of a historical-comparative approach made it possible to reconstruct the evolution of social and economic relations, in particular, to consider land claims in the region on a chronological and territorial basis. The scientific novelty attempt was made to comprehensively reconstruct the process of formation of a system of land holdings in starostvo of Oster in the second half of the sixteenth - early of the seventeenth century. Conclusions. In the second half of the sixteenth - early seventeenth centuries the formation of the system of land tenures in starostvo of Oster (Kyiv Voivodship) continued. The largest tracts of land were distributed by the starosta Lavrin and Mykhailo Ratomski. The establishment of settlements, most of which were granted by law, were directly dependent on the needs of the military organization of the region. During this period a significant influx of nobles from Volyn and Kyiv region was recorded. The active penetration of the Polish aristocracy began only at the beginning of the seventeenth century.
