why did france declare war on prussia in 1870
Franco-Prussian War The Franco-Prussian War or Franco-German War (German: Deutsch-Französischer Krieg, French: Guerre franco-allemande), often referred to in France as the War of 1870 (19 July 1870 – 10 May 1871) or in Germany as 70/71, was a conflict between the Second French Empire of Napoleon III and the German states of the North German Confederation led by the Kingdom of Prussia. The conflict was caused by Prussian ambitions to extend German unification and French fears of the shift in the European balance of power that would result if the Prussians succeeded. Some historians argue that the Prussian chancellor Otto von Bismarck deliberately provoked a French attack in order to draw the independent southern German states—Baden, Württemberg, Bavaria and Hesse-Darmstadt—into an alliance with the North German Confederation dominated by Prussia, while others contend that Bismarck did not plan anything and merely exploited the circumstances as they unfolded. None, however, dispute the fact that von Bismarck must have recognized the potential for new German alliances, given the situation as a whole. [8]
British and French declaration of war on Germany The Declaration of war by France and the United Kingdom was given on 3 September 1939, after German forces invaded Poland. Despite the speech being the official announcement of both France and the United Kingdom, the speech was given by the British Prime Minister Neville Chamberlain, in Westminster, London.[1]
