The area lies between the southern shore of the Loire estuary and the Marais breton (Breton marshlands), bordered to the west by the Baie de Bourgneuf (Bourgneuf Bay) and on the east by the Lac de Grand-Lieu (Grand-Lieu Lake) and a network of small rivers. Its main towns are Rezé (which was its capital and the see of a Catholic Diocese of Rezé from 510 to 851), Pornic, Paimbœuf and Machecoul (another historical capital city).
History
In the early 9th century the area formed part of Frankish territory, but was coveted by the Breton ruler Nominoe. Nominoe and his son Erispoe won a series of victories over the Franks between 843 and 851, resulting in the Treaty of Angers (851) between Charles the Bald and Erispoe, which gave "Ratense" or Pays de Retz to Brittany.[1]
In subsequent centuries was conflict between Brittany and Anjou over the area. The notorious medieval serial killer Baron Gilles de Rais was from the area and sexually assaulted and tortured a large number of local peasant children before murdering them.
