title: Jeremi Michał Wiśniowiecki w planach wojny tureckiej Władysława IV
abstract: The article presents the role of the Ruthenian voivode Jeremi Wiśniowiecki in King Vladislaus IV’s plans for war with Turkey and contains the publication of the document granting the fief, which was to make it easier for the prince to act in accordance with the king’s plan. The King could not obtain the Sejm’s consent to war and he thus persuaded Wiśniowiecki to undertake an expedition in 1647 aimed at inciting war with Crimea. This did not happen, but the prince agreed to take further action. T
