Following Frederick's death in 1105, Agnes married Leopold III (born 1073; died 15 Nov. 1136) the Margrave of Austria (1095 till 1136). Leopold was the son of Margrave Leopold II and Ida of Formbach-Ratelnberg. According to legend, a veil lost by Agnes and found by Leopold years later while hunting instigated him to found the monastery of Klosterneuburg.
