Aleksander Leon Kostka-Napierski (1620–1651), Polish captain during the Thirty Years' War in Swedish service, participant of battle in Germany and organizer of the Kostka-Napierski Uprising. According to the historian prof. , Napierski was in service to Khmelnytsky. Professor of History Janusz Tazbir was of a similar opinion. However, other historians, such as Adam Kersten, cautiously connect Kostki-Napierski with the Swedish king, with Khmelnytsky, or with the court of Rákóczi.
