Third-Republic France. This dataset traces, year by year, the administrative boundaries of France’s Third Republic, which governed from 1870 to 1940, when the Vichy Regime took power. The dataset consists of annual shapefiles delineating the country’s départements, arrondissements, and cantons; as well as for its “most significant special administrative constituencies: military, judicial and penitentiary, electoral, academic, labor inspection, and ecclesiastical.”
