Archduke Albert VI of Austria (d. 1463)
Albert VI (German: Albrecht VI.; 18 December 1418 – 2 December 1463), a member of the House of Habsburg, was Duke of Austria from 1424, elevated to Archduke in 1453. As a scion of the Leopoldian line, he ruled over the Inner Austrian duchies of Styria, Carinthia and Carniola from 1424, from 1457 also over the Archduchy of Austria until his death, rivalling with his elder brother Emperor Frederick III. According to tradition, Albert, later known as the Prodigal, was the exact opposite of Frederick: energetic and inclined to thoughtlessness.
