Elizabeth was in fact better connected to powerful German rulers than her future husband: a descendant of earlier monarchs, for example Emperor Frederick Barbarossa, she was also a niece of the Bavarian dukes, Austria's important neighbors.

After Rudolf had defeated his rival King Ottokar II of Bohemia in the 1278 Battle on the Marchfeld, he invested his son Albert with the duchies of Austria and Styria at the Imperial Diet in Augsburg on 17 December 1282.

[2] Albert initially had to share the rule with his younger brother Rudolf II, who nevertheless had to waive his rights according to the Treaty of Rheinfelden the next year.

On 1 May 1308 Albert was murdered by his nephew John Parricida near Windisch, Swabia (in modern Switzerland).

Afterward Elisabeth had the Poor Clare monastery of Königsfelden erected at the site, where she also died on 28 October 1312 and was also buried.
