The Champagne fairs were an annual cycle of trade fairs which flourished in different towns of the County of Champagne in Northeastern France in the 12th and 13th centuries, originating in local agricultural and stock fairs. Each fair lasted about 2 to 3 weeks. The Champagne fairs, sited on ancient land routes and largely self-regulated through the development of the Lex mercatoria, became an important engine in the reviving economic history of medieval Europe, "veritable nerve centers" serving as a premier market for textiles, leather, fur, and spices. At their height, in the late 12th and the 13th century, the fairs linked the cloth-producing cities of the Low Countries with the Italian dyeing and exporting centers, with Genoa in the lead, dominating the commercial and banking relations operating at the frontier region between the north and the Mediterranean. The Champagne fairs were one of the earliest manifestations of a linked European economy, a characteristic of the High Middle Ages.
