List of Famous people with last name Posthumous

Ladislaus the Posthumous, known also as Ladislas, was Duke of Austria, and King of Hungary, Croatia and Bohemia. He was the posthumous son of Albert of Habsburg with Elizabeth of Luxembourg. Albert had bequeathed all his realms to his future son on his deathbed, but only the estates of Austria accepted his last will. Fearing an Ottoman invasion, the majority of the Hungarian lords and prelates offered the crown to Vladislaus III of Poland. The Hussite noblemen and towns of Bohemia did not acknowledge the hereditary right of Albert's descendants to the throne, but also did not elect a new king.

Stephen the Posthumous was the posthumous son of King Andrew II of Hungary by his third wife, Beatrice d'Este. He was regarded as bastard son of infidelity by his much older half-brothers, including King Béla IV of Hungary, and was not allowed to receive ducal revenues from Hungary to which he would have been entitled as son of a Hungarian king.
