Life
In 1209 Erard, with the consent of his unnamed wife, confirmed a donation to Basse-Fontaine by a certain Agnete, specified as domina of Chacenay, probably his grandmother Agnes de Brienne.During the War of the [Succession of Champagne|succession crisis of Champagne], Erard was the strongest support of Erard of Brienne-Ramerupt and was the last to reconcile with Blanche of [Navarre, Countess of Champagne|Blanche of Navarre].
Uneasy with the result in Champagne, Erard took part in the Fifth Crusade, but was back in Europe by 1220. In July 1219 Erard's cousin, Hervé, Count of Nevers, confirmed a donation Erard had made to the Teutonic Knights, while Erard was at the siege of Damietta. Upon his return, Erard paid homage to Theobald, Count of Champagne and made a donation to the convent of Argensolles, which had been founded by Blanche of Navarre.
He was a patron of the trouvère Guiot de Dijon. He was buried in the Abbey of Clairvaux, 16 June 1236.
