During the Middle Ages, Troyes was an important trading town, and gave its name to the troy unit of weight. The Champagne cloth fairs and the revival of long-distance trade and new extension of coinage and credit were the real engines that drove the medieval economy of Troyes. Troyes and Provins had been administrative centers in Charlemagne's empire that developed into the central towns of the County of Champagne and the Brie Champenoise Region.
As such Troyes' geographic key position, the concentration of expertise on international trade, coinage and credit, all under the protection of the lords of the Earldom of the Champagne, was the ideal site for sparking, founding and harbouring the first "multinational enterprise" on trade and finance: the Knights Templar.
