The County of Auxerre was a medieval and early modern county in the West Frankish Kingdom, and consequently in the Kingdom of France. Its capital was the city of Auxerre. It was commonly associated with the Duchy of Burgundy.
History
The first count attested by the sources is one Ermenaud, a companion of Charlemagne who reigned around 770. Sometime around 853/858, king Charles the Bald handed over the county to his cousin Conrad the Younger, from the Elder House of Welf, whose father Conrad the Elder was lay abbot of Saint-Germaine in Auxerre. When he left for Transjuran Burgundy, the county was assigned to Robert the Strong. After the latter's death, he county was administered by Hugh the Abbot of Saint-Germain d'Auxerre. County of Auxerre was later included into the Burgundian dominion of duke Richard the Justiciar.
Count John IV sold it to the King of France in 1370. After the Treaty of Arras (1435) 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.
