Havel Medek of Valdek
Havel Medek of Valdek was a Bohemian noble. He was the son of Oldřich Medek of Valdek, the lord of Týnec nad Sázavou. Havel is mentioned as residing in Týnec in 1349. In 1390, Havel besieged Talmberk Castle, conquering it and capturing the lord Diviš of Talmberk. Havel then began styling himself as Medek of Talmberk.
Diviš was imprisoned for seven years before the provincial courts declared Havel's seizure illegal. Havel was summoned to court in Prague but did not attend. Diviš was subsequently released and Havel returned the castle.
