CHÂLONS Châlonnais (pays).
Medieval county around the town of Châlons-sur-Marne, recently renamed Châlons-en-Champagne, in eastern France;
- A Bishopric;
- A généralité in the Ancien Régime.
The town is today the capital of the Department of the Marne and of the Champagne-Ardenne region.
The County came into the hands of the Bishop of Châlons, though the power was exercised until 1064 by the Count of Champagne. The Bishop was one of the six ecclesiastical Peers of France. By the 14th century the King of France exercised the actual powers, and Châlons became part of the province of Champagne.
The diocese of Châlons-sur-Marne belongs to the province of Reims; it was temporarily suppressed, 1790-1822.
The généralité of Châlons was created in 1542 and was similar in extent to the gouvernement of Champagne, except that the southwest of Champagne (the Brie and the region around Sens) were in the généralité of Paris.
