...Holstein declare themselves independent of Denmark on the same day that the French Second Republic comes into being, March 24.
The Schleswig-Holsteiners, being inspired from the successes of the French in the revolution in Paris of February 1848, had sent a deputation to Copenhagen to demand the immediate recognition by King Frederick VII of a joint state of Schleswig-Holstein previous to its admittance into the German Confederation.
King Frederick's reply had admitted the right of Holstein as a German confederate state to be guided by the decrees of the Frankfurt diet, but declared that he had neither "the power, right, nor wish" to incorporate Schleswig into the confederation.
