Casimir IV (Polish: Kazimierz IV or Kaźko Słupski, German: Kasimir IV or Kasimir V ) (1351 – January 2, 1377) was a duke of Pomerania in Pomerania-Stolp since 1374. After grandfather"s death in 1370, young Casimir initially became his partial successor, as the last will gave him lands of Dobrzyń, Bydgoszcz, Kruszwica, Złotów and Wałcz as fiefs. Yet, his ambitions were soon thwarted by Louis I of Hungary, who became the next king of Poland on the ground of earlier pacts, and nullified the Piast"s last will.
