Since Boček II was the first born, he inherited the larger part of his father's possessions, which were mostly in eastern Bohemia.
In 1394 he was among the League of Lords who signed the initiative of the Margrave Jobst of Moravia, a joint statement with which they turned against the king, who was eventually captured.
From Gerhards he inherited among others Kunštát, Bouzov, Moravská Třebová, Pyšolec Castle, Boskovice, Týnec na Moravě and Velké Bílovice.
In early 1415, Boček II signed a petition, in which the high Bohemian nobles protested against the capture of Jan Hus.
Later that year, after Hus was burned at the stake, Boček was the third noble to sign a letter of complaint by the Bohemian nobility.
They would become counts of Kladsko, and as Dukes of Münsterberg they would found the Silesian (Münsterberg-Oels) branch of the Poděbrady family.
