W sprawie polsko-ruskich relacji w pierwszej połowie XII w. Wokół małżeństwa Bolesława Wysokiego ze Zwienisławą Wsiewołodówną

This article, a study in dynastic microgenealogy clarifies, on a given example, the motivations and both political and cultural consequences of a certain Polish-Russian marriage. This concerns the union of Bolesław I the Tall (Wysoki, 1127-1201), the eldest son of the Polish lord Władysław II the Exile, and Zwienisława, the eldest daughter of the Duke of Kiev, Wsiewołod Olegowicz. The article corrects certain chronological inconsistencies embedded in literature, concerning the date of the marriage, as well as resulting from it campaign of Russian forces to aid Władysław II, who was fighting the Junior Dukes. According to the author, the marriage of Boleslaw and Zwienisława took place between March 1, 1142 and the atmospheric winter ending that year. The author also investigated the issue of, almost universally incorrectly interpreted by historians, Polish political situation in Russia. The author assures that aside from the episode of 1139 there was no conflict between Olegowiczes, led by Wsiewołod Olegowicz and Monomachowiczes – the descendants of Włodzimierz Wsiewołodowicz Monomach. This could not have been a factor contributing to the reasons for marriage of Bolesław and Zwienisława.
