The Treaty of Paris of 24 February 1812 between Napoleon I of France and Frederick William III of Prussia established a Franco-Prussian alliance directed against Russia. On 24 June, Prussia joined the French invasion of Russia. The unpopular alliance broke down when the Prussian contingent in French service signed a separate armistice, the Convention of Tauroggen, with Russia on 30 December 1812. On 17 March 1813, Frederick William declared war on France and issued his famous proclamation "To My People".[1]
According to East German historiography, the Franco-Prussian alliance strengthened the hand of the monarchy and nobility against social and national movements. In the end, however, the action of the masses—disarming retreating French troops; collecting money, food and clothes for Russian prisoners; clashing with French troops—were definitive in ending it.[2]
