Mieszko I, Duke of Cieszyn disappeared. Is unknown why this happened, because at that time he was only around fifty-years-old and was still considered young enough. The government of the Duchy was increasingly absorbed by his sons Wladyslaw and Kazimierz. The only sign of his political activities during this time was the lease of the Czech city of Kęty to the Bishop of Kraków, Jan Muskata, a strong opposer to the rule of Władysław I the Elbow-high in Greater Poland. However, in contrast to his brother Bolko I, Mieszko didn't support the Rebellion of wójt Albert in 1311. Mieszko was known for his generosity to
Mieszko II Lambert to Hungary because during his travel he was stopped by Rus' troops. King Stephen I of Hungary wasn't favorable to accepting him in his country. Without alternatives, Mieszko II went to Bohemia. Duke Oldřich once again imprisoned him. This time the King wasn't counting with the Imperial support. Mieszko II was not only imprisoned but also castrated, which was to be a punishment to Bolesław I the Brave, who blinded Duke Boleslaus III the Red (Oldřich's brother) thirty years before. Mieszko II and his wife never reunited again; according to some sources they were either officially divorced or only separated.
