Leszek II the Black
Despite this success, Ziemomysł continued with his German-Pomeranian politics, which caused a new revolt by his subjects, who called again Bolesław for help: in 1271 he invaded the Duchy of Inowrocław and forced Ziemomysł to flee. Bolesław retained the Duchy until 1273, when he gave it to Ziemomysł's brother Leszek II the Black, except for Radziejów and Kruszwica, which remained in Greater Poland.
