First marriageEdit

In 1079, aged seven, Agnes was betrothed to Frederick, a member of the Hohenstaufen dynasty; at the same time, Henry IV invested Frederick as the new duke of Swabia.[4] The couple married in 1086, when Agnes was fourteen. They had twelve children, eleven of whom were named in a document found in the abbey of Lorsch:

  • Hedwig-Eilike (1088–1110), married Friedrich, Count of Legenfeld
  • Bertha-Bertrade (1089–1120), married Adalbert, Count of Elchingen
  • Frederick II of Swabia[5]
  • Hildegard
  • Conrad III of Germany[5]
  • Gisihild-Gisela
  • Heinrich (1096–1105)
  • Beatrix (1098–1130), became an abbess
  • Kunigunde-Cuniza (1100–1120/1126), wife of Henry X, Duke of Bavaria (1108–1139)[6]
  • Sophia, married Konrad II, Count of Pfitzingen
  • Fides-Gertrude, married Hermann III, Count Palatine of the Rhine[5]
  • Richildis, married Hugh I, Count of Roucy

Second marriageEdit

Following Frederick's death in 1105,[7] Agnes married Leopold III (1073–1136), the Margrave of Austria (1095–1136).[8] According to a legend, a veil lost by Agnes and found by Leopold years later while hunting was the instigation for him to found the Klosterneuburg Monastery.[1]

Their children were:[9]

According to the Continuation of the Chronicles of Klosterneuburg, there may have been up to seven other children (possibly from multiple births) stillborn or who died in infancy.

In 2013, documentation regarding the results of DNA testing of the remains of the family buried in Klosterneuburg Abbey strongly favor that Adalbert was the son of Leopold and Agnes.[10]

In 1125, Agnes' brother, Henry V, Holy Roman Emperor, died childless, leaving Agnes and her children as heirs to the Salian dynasty's immense allodial estates, including Waiblingen.

In 1127, Agnes' second son, Konrad III, was elected as the rival King of Germany by those opposed to the Saxon party's Lothar III. When Lothar died in 1137, Konrad was elected to the position.[1]
