Beginning in the 1870s, a great many Bretons began arriving in Paris. Every age has its pariahs, and in 1900, the ?pariahs of Paris? were the Bretons, the last distinct group of provincials to come en masse to the capital city. The pariah designation took hold in Paris, in Brittany, and among historians. Yet the derision of recent migrants can be temporary. Tracing the changing status of Bretons in Paris since 1870, Leslie Page Moch demonstrates that state policy, economic trends, and the attitudes of established Parisians and Breton newcomers evolved as the fortunes of Bretons in the capital improved. Drawing on demographic records and the writings of physicians, journalists, novelists, lawyers, and social scientists, Moch connects internal migration with national integration. As the pariahs of yesterday, Bretons are an example of successful integration into Parisian life. At the same time, their experiences show integration to be a complicated and lengthy process.
