[1] In 1163, Count Henry I of Champagne made himself a hostage of the German emperor Frederick I on behalf of his lord, King Louis VII of France.
When Louis did not appear for a scheduled meeting, Henry was forced to do homage to Frederick for several castles, including Dampierre, that lay along the Franco-German border.
This had the result of placing Renard's lordship in Germany, and the border thus ran through the county of Champagne.
Renard also stood as surety for the priory of Saint-Martin-des-Champs when the prior donated a rent to the abbey of Monthiers.
[4] In 1172, Renard appeared in the first edition of the Feoda Campaniae, a list of all the fiefs of the county of Champagne.
