The vast region around the southern basin of the Dnieper, the whole territory comprising the provinces of Kiev, Poltava, and Chernigov, and including parts of Podolia and Volhynia, was subject to the political power of the Polish kings and the economic dominion of the Polish magnates. Enormous estates, comprising a large number of villages populated by Russian peasants, were here in the hands of wealthy Polish landlords, who enjoyed all the rights of feudal owners. The enthralled peasants, or khlops, as they were contemptuously nicknamed by the Polish nobles, were strange to their masters in point of religion and nationality. In the eyes of the Catholics, particularly in those of the clergy, the Greek Orthodox faith was a "religion of khlops," and they endeavored to eradicate it by forcing upon it compulsory church unions[121] or by persecuting the "dissidents." The Poles looked upon the Russian populace as an inferior race, which belonged more to Asia than to Europe. In these circumstances, the economic struggle between the feudal landlord and his serfs, unmitigated by the feeling of common nationality and religion, was bound to assume acute forms. Apart from the oppressive agricultural labor, which the peasants had to give regularly and gratuitously to the landlord, they were burdened with a multitude of minor imposts and taxes, levied on pastures, mills, hives, etc. The Polish magnates lived, as a rule, far away from their Ukrainian possessions, leaving the management of the latter in the hands of stewards and arendars.
