Amidst all the movements and convulsions in Germany which followed in the wake of the February Revolution and its subsequent development, the campaign for the Imperial Constitution stands out owing to its classically German character. Its occasion, its appearance, the way it conducted itself, its whole course, were through and through German. In the same way as the June days of 1848 mark the degree of the social and political development of France, so the campaign for the Imperial Constitution marks the degree of the social and political development of Germany, and especially of South Germany.
The soul of the whole movement was the class of the petty bourgeoisie, usually known as the burghers, and it is precisely in Germany, and especially in South Germany, that this class is in preponderance. It was the petty bourgeoisie which, in the "March Clubs", the democratic constitutional clubs, the patriotic clubs, the multitude of so-called democratic press, swore to the Imperial Constitution its Grutli oaths, as widespread as they were innocuous, and carried on its fight against the "refractory" princes of which the only immediate result was admittedly the elevating consciousness of having fulfilled one's civic duty. It was the petty bourgeoisie, represented by the resolute and so-called extreme Left of the Frankfurt Assembly, i.e. in particular by the Stuttgart Parliament and the "Imperial Regency", which furnished the entire movement with its official leadership; lastly, the petty bourgeoisie was dominant in the local committees of the provincial diets, committees of public safety, provisional governments and constituent assemblies which in Saxony, on the Rhine and in South Germany won greater or lesser credit in the cause of the Imperial Constitution.
