After the coup d état, which marked the end of the revolution of 1848, France fell under the yoke of the Napoleonic regime for a period of 18 years. This regime brought upon the country not only economic ruin but national humiliation. In rising against the old regime the proletariat under took two tasks—one of them national and the other of a class character—the liberation of France from the German invasion and the socialist emancipation of the workers from capitalism. This union of two tasks forms a unique feature of the Commune.
