Foreign Policy in the Age of the Reformation: French Involvement in the Schmalkaldic War, 1544–1547

On 24 April 1547 the forces of the leading protestant princes in Germany were annihilated at Miihlberg by Charles V, and the political wing of protestantism received a blow from which it never entirely recovered. Events during the preceding year had moved with a startling rapidity. Diplomats had widely expected a drawn contest in the summer of 1546, while John Frederick of Saxony and Philip of Hesse had sent a series of missions to France and England to request the military aid and intervention which might tip the balance decisively against the emperor. The diplomatic experts of the Schmalkaldic League had expected France to take advantage of the emperor's difficulties in Germany. The outbreak of war there might seem to have brought to fruition decades of French efforts to cripple the emperor by embroiling him with his German subjects, and 1546 certainly saw a culmination of French diplomatic activity across the Rhine. Yet the outcome of the frenetic negotiations which accompanied the war showed, on the part of the French, a lack of decisiveness at this critical time which is not easy to explain. Four years before, a grand anti-Habsburg coalition had been the pivotal point of French foreign policy. Now, in 1546, any chances of such a coalition were frittered away in petty negotiations with the English and a marked lack of faith between the French and the Germans.
