Casimir II the Just
Another important year in Bolesław could be 1191, when his father, using the absence of Casimir II the Just (who was involved in the Kievan Rus' succession disputes) seized and conquer Kraków. Then, for unknown reasons, Mieszko III didn't took personally the government of the capital, but gave them to Bolesław (although some sources believed that the prince who was appointed Governor of Kraków was Mieszko the Younger). Bolesław's rule as governor in Kraków wasn't too long, because soon Casimir II the Just could recover his authority over the capital and imprisoned his nephew. However, the victorious Casimir II acted generously and sent the prince with his father.
