Matthias Corvinus
During the Bohemian War (1468–1478) the House of Tunkle supported George of Poděbrady and was defeated in the battle of Zvole. After this fiasco, the house changed sides and fought for Matthias Corvinus in the battle of Ivanovice ve Slezsku. Despite the fact that the House of Tunkl lost this battle, Matthias Corvinus recognized their willingness to collaborate and gave them several hereditary rights.
