Popponids
Like the French royal Capetian dynasty, the Elder Babenbergs descended from the Robertians. The earliest known Babenberg was one Poppo, maybe a descendant of the Frankish count Cancor. In the early 9th century he appeared as a count in the Grabfeld, a historic region in northeastern Franconia bordering on Thuringia. One of his sons, Henry, sometimes called margrave and duke in Franconia under King Charles the Fat of East Francia, fell fighting against the Normans in 886; another, Poppo, was margrave in Thuringia from 880 to 892, when he was deposed by King Charles successor Arnulf of Carinthia. The Popponids had been favoured by Charles the Fat, but Arnulf reversed this policy in favour of the rival family of the Conradines from the Lahngau in Rhenish Franconia.
The leaders of the Babenbergs were the three sons of Duke Henry, who called themselves after their castle of Babenberg on the upper Main, around which their possessions centred. The city of Bamberg was built around the ancestral castle of the family.
