County of Auxerre
The County of Auxerre is a former state of current central France, with capital in Auxerre.History
The first count attested by the sources is one Ermenaud, a companion of Charlemagne who reigned around 770. In 859 Charles the Bald handed over the county to his cousin Conrad II of Burgundy. When he revolted, the county was assigned to Robert the Strong. After the latter's death, Hugh the Abbot was count, but named a viscount in his lieu; later Auxerre was absorbed in Richard of Burgundy's dominion.
It returned to the Capetians with Renauld I of Nevers. Auxerre remained part of Nevers until 1262. It was sold to the King of France in 1370. After the Treaty of Arras between Charles VII of France and Philip III of Burgundy, it returned once again to the latter. In 1477, with the annexion of Burgundy, it became definitively part of France.- Ermenaud I of Auxerre c. 758
