Formerly ruled by thecounts of Champagne, its western edge is about 160 km (100 miles) east of Paris. The cities ofTroyes,Reims, andÉpernay are the commercial centers of the area. In 1956, most of Champagne became part of the French administrativeregion ofChampagne-Ardenne, which comprised four departments:Ardennes,Aube,Haute-Marne, andMarne. From 1 January 2016, Champagne-Ardenne merged with the adjoining regions ofAlsace andLorraine to form the new region ofGrand Est.
The nameChampagne, formerly writtenChampaigne, comes from French meaning "open country" (suited to military maneuvers) and fromLatincampanius meaning "level country" or "plain"[2] which is also the derivation of the name of the Italian region ofCampania. The toponym dates back to the Renaissance describing its vastchalk lined flat landscape.[3]
