Duchy of Alsace

640 CE – 740 CE (approx.) · capital Obernai

Frankish frontier duchy between the Vosges and the Rhine, ruled by the Etichonid family whose saint, Odile, is the patron of Alsace.

Origins

In the mid 7th century the Merovingian kings of Austrasia set up a duchy in Alsace to control the border with the Alemanni. The first known duke was Gundoin, and from around 662 power passed to Adalric, also called Eticho, founder of the Etichonid dynasty.

Rule and society

The dukes governed from their estates around Obernai and founded many monasteries. Adalric's daughter Odile founded the convent of Hohenburg on the mountain now called Mont Sainte-Odile, and his descendants endowed abbeys such as Honau and Murbach.

Decline and legacy

Around 740, after the death of Duke Liutfrid, the Carolingian mayors abolished the duchy, which had grown too independent, and divided Alsace into two counties, the Nordgau and the Sundgau. The Etichonid family remained powerful and gave rise to several later noble houses.
