Vilém z Landštejna
Vilém z Landštejna (died 1356) was one of the most powerful Bohemian lords under King John of Luxembourg and later a loyal supporter of Emperor Charles IV. The son of Vítek z Landštejna, he inherited Třeboň and Landštejn and enlarged his domains.
He ended his career as Supreme Burgrave of Bohemia (1351–1356), and died of wounds from a duel with his kinsman Jindřich of Hradec over a trade route.
