Frédéric Ier de Souabe

Duke of Swabia (1079–1105) · Count

First Duke of Swabia from the House of Staufen, Frédéric Ier (c. 1050–1105) is the builder of the castle of Hohenstaufen, erected around 1070 on the conical summit overlooking present-day Göppingen. While still a simple count, he probably transformed a more modest fortification into a castle, an allodial property of his family predating his ducal investiture of 1079. He was the first to take the name of the mountain, later passed on to the entire dynasty. A loyal supporter of Henri IV, whose daughter Agnès he married, he also founded the abbey of Lorch, the family necropolis where he was buried.

Histoire & patrimoine

The castle that gave its name to a dynasty

Written sources, first and foremost Otton de Freising, place the construction of the castle on the Hohenstaufen around 1070. Frédéric was then only a count: the castle was therefore private property (alleu) and not an imperial castle. He was the first member of the family to take his name from the mountain and its fortress, a name later borne by the kings and emperors “Staufen”. The exact dates of construction are not known.

Frédéric Ier de Souabe dans l’histoire

A duke loyal to Henri IV

Invested with the Duchy of Swabia in 1079 amid the Investiture Controversy, Frédéric supported Henri IV against the anti-kings and their allies; he suffered setbacks (Höchstädt 1081, loss of Augsburg in 1084 according to the ADB). The NDB and ADB differ on the date of Berthold de Zähringen's renunciation of the duchy (1096 or 1098).
