Upper Burgundy (green) and Alamannia (orange), including Conrad's old counties of Argengau and Linzgau (c. 1000)

Conrad the Elder (died about 864) was a prominent noble in the Carolingian Empire, and member of the Elder House of Welf.Template:Sfn He was count of several counties in Alamannia, most notably the counties of Argengau and Linzgau, north of the Lake Constance. Conrad was son of count Welf I and countess Heilwig. Both of Conrad's sisters married into the Carolingian dynasty: the elder Judith was second wife of emperor Louis the Pious, while younger Emma was wife of king Louis the German of East Francia.Template:Sfn

In 853-858, Conrad's sons left East Francia,Template:Sfn and went over to king Charles the Bald of West Francia, who was Judith's son and thus Conrad's nephew.Template:Sfn Since Conrad already held some lands in the West-Frankish County of Auxerre,Template:Sfn including the position of a lay abbot of Saint-Germaine in Auxerre,Template:Sfn his son Conrad the Younger was appointed Count of Auxerre by king Charles, while the other son Hugh became a monk and Abbot of Saint-Germain d'Auxerre. It is assumed that king Louis of East Francia reacted by confiscating most of their old fiefs and lands in Alamannia and Bavaria.Template:Sfn

The Miracula Sancti Germani calls Conrad Chuonradus princeps (prince, sovereign), when recording his marriage. By some accounts his wife re-married to Robert the Strong after his death.
