Duchy of Münsterberg
Heinrich the Younger of Poděbrady was a son of King George of Podebrady of Bohemia from his second marriage with Johana of Rožmitál. He received a humanist training and participated in knightly tournaments. His father, George, was King of Bohemia, but this crown was not heritable. George persuaded Emperor Frederick III in 1459 to appoint his eldest son Victor to Imperial Count. In 1462, Frederick also appointed Henry the Younger and his elder brother Henry the Elder to Imperial Count. Earlier, George had appointed his three sons Count of Glatz and enfeoffed them with the County of Glatz and the Duchy of Münsterberg. In 1465 he also enfeoffed them with the Duchy of Opava, which he had acquired in 1464.
