This 620-page richly illustrated Ukrainian-language monograph analyses one of the most important events in the central- and eastern-European diplomatic history of the mid 17th century, the Vilnius negotiations between Muscovy and the Polish-Lithuanian Commonwealth that took place from 22 August to 3 November 1656. In particular, the monograph analyzes the influence of these negotiations, to which the Cossack delegation was not admitted, on Cossack Ukraine and the policies of Hetman Bohdan Khmelnytsky. The Vilnius negotiations are presented in the book as the antecedent to the Treaty of Andrusovo of 1667 and the Eternal Peace of 1686 between Muscovy and Poland, as a result of which Ukraine was divided in half along the Dnipro River for over a century. Analysing the Vilnius negotiations and its impact on Ukraine in light of international politics and diplomacy, Yaroslav Fedoruk defines Ukraine’s position on the map of the 17th-century Europe.
