Formerly ruled by the counts of Champagne, its western edge is about 160 km (100 miles) east of Paris. The cities of Troyes, Reims, and Épernay are the commercial centers of the area. In 1956, most of Champagne became part of the French administrative region of Champagne-Ardenne, which comprised four departments: Ardennes, Aube, Haute-Marne, and Marne. From 1 January 2016, Champagne-Ardenne merged with the adjoining regions of Alsace and Lorraine to form the new region of Grand Est.
Etymology
The name Champagne, formerly written Champaigne, comes from French meaning "open country" (suited to military maneuvers) and from Latincampanius meaning "level country" or "plain"[2] which is also the derivation of the name of the Italian region of Campania. The toponym dates back to the Renaissance describing its vast chalk lined flat landscape.[3]
