The Champagne Riots of 1910 and 1911 resulted from a series of problems faced by grape growers in the Champagne area of France. These included four years of disastrous crop losses, the infestation of the phylloxera louse (which destroyed 15,000 acres (6,100 ha) of vineyards that year alone), low income and the belief that wine merchants were using grapes from outside the Champagne region. The precipitating event may have been the announcement in 1908 by the French government that it would delimit by decree the exact geographic area that would be granted economic advantage and protection by being awarded the Champagne appellation. This early development of Appellation d'Origine Contrôlée regulation benefitted the Marne and Aisne districts to the significant exclusion of the Aube district which included the town of Troyes—the historic capital of the Champagne region.[1]
