PRIMARY COLLECTION REGISTERS OF THE ESTATES OF PRINCE V.-K. OF OSTROH 1577

The article examines the collection of primary collection registers of estates of the book V.-K. Ostrozki in 1577. They are an important element in the structure of descriptive-statistical sources from the history of Volyn. The primary registers were created by landowners or their representatives and were the basis for creating summary tax documents. The latter are widely used in research, including source studies and practice. Primary registers are not sufficiently introduced into scientific circulation. The importance of the primary registers of 1577 also lies in the fact that they reflected the devastation of Volyn after the Tatar attacks of 1575 and 1577. The presence of primary (1570 and 1577) and general (1570, 1577, 1583, 1589) collections registers creates opportunities to examine the state and dynamics of the development of social and economic phenomena. Other sources of a descriptive and statistical nature are unknown for the Volyn estates of the princes of Ostroh of the second half of the 16th century. The most important feature of collections registers is the display of social indicators of the urban and rural populations. Documentation of a primary nature, which was created by order of the owners and related to individual estate complexes, contains a number of testimonies that were lost during the generalization. Such are the formulary characteristics and language of primary fiscal notes, the level of implementation of economic innovations, elements of the gender structure of the population, anthroponymy, names of owners, etc. Primary collections registers were introduced on the territory of Volyn at the end of 1569, and their registration did not have an established standard due to the lack of tradition and experience. The nature of filing tax statements into the registers also differed. These features, even in the registers created by the same domain office, differed significantly. Tax documentation of the estates of V.-K. Ostrozky has a sufficiently high territorial representativeness. The entirety of tax documentation constitutes a single source system, which requires the study of all its elements, including primary tax registers.
