Ukrainian-Swedish Union Of The 1650S In The Interpretations Of Polish Historians Of The First Half Of The XX Century

Formulation of the problem. The events of the middle of the seventeenth century are among the most important ones in the historical destiny of the Ukrainian and Polish peoples. The protracted war divided the peoples once united within a common state and led to their mutual exhaustion. The neighboring states also intervened in the military conflict, trying to use the Ukrainian and Polish sides to their advantage. In the history of the Commonwealth, the events of the second half of the 1650s were called the “flood”, when most of its territories were occupied by the armies of the enemy. However, the intervention of Sweden and Semyhorod opened up prospects for a new anti-Polish coalition for the Cossacks led by B. Khmelnytsky. These important events are reflected in the works of many Polish historians of the first half of the twentieth century and became the basis for a variety of historiographical concepts and assessments.
