Two important monasteries were founded in the department: one at [[Clairvaux Abbey|Clairvaux]] in 1114, created by [[Bernard of Clairvaux]], the other was the [[Abbey of the Paraclete]] near Nogent-sur-Seine, by his illustrious rival, [[Pierre Abélard]] and of which [[Héloïse d'Argenteuil]] was the first [[abbess]]. Bernard of Clairvaux was noted for his eloquence at the [[Council of Troyes 1129|Council of Troyes]] and his preaching of the [[Second Crusade]] which had no result and whose outcome was disastrous.

The reunion of [[Champagne (province)|Champagne]] with the kingdom of France was finalised in 1361. Yet people wanted absolutely the incorporation of Champagne but in 1328 [[Philip VI of France|King Philip VI]] gave the city of [[Bar-sur-Seine]] to Philippe de Croy. The inhabitants, however, ransomed him to return it to the king on the condition that it become inalienable.
