ENCould the crucible of military conflicts in which the Grand Duchy of Lithuania and Muscovy became embroiled at the end of the fifteenth century over which was to be heir to the territory of Ancient Rus' and which became a regional Livonian war in the mid-sixteenth century over control of the Baltic Sea, have had an influence over political culture in East-Central Europe? Do war and political culture on the whole have no interconnection? The aim of this paper is to show how changes took place in the political arena of a region experiencing growing military conflict, and how these changes may be assigned to the category of political cultural phenomena, to examine war as a factor, which stimulated the development of philosophy, and the search for new means of expressing political thought.
