In 1278 King Rudolph I of Germany, a scion of the Swabian House of Habsburg, finally seized both duchies from King Ottokar II of Bohemia, whom he defeated in the Battle on the Marchfeld. Rudolph's son King Albert I of Germany defended his hegemony against the rival Prince-Archbishops of Salzburg to the west and in 1298 made the lands of Ischl a present to his wife Countess Elisabeth of Gorizia-Tyrol.
