The unification of Germany, c1840–71 - 4 Prussia and the Klein-…

The idea

The Franco-Prussian War (1870–71) was the final stage of German unification. Its significance lies in three linked outcomes. First, it increased support for German nationalism: the war against a foreign enemy rallied the south German states to Prussia’s side, overcoming earlier reluctance and making unity popular. Second, it strengthened Bismarck’s position: his diplomacy isolated France, and victory made him indispensable to the new order. Third, it created a German Empire: the defeat of France allowed the proclamation of the Empire at Versailles in January 1871, with Wilhelm I as Kaiser. The Treaty of Frankfurt (May 1871) confirmed this new balance: France ceded Alsace-Lorraine, paid an indemnity, and accepted German unification. Together, these outcomes show how war and treaty turned Prussian leadership into a German Empire.

What earns the marks

• Explains how the war increased support for German nationalism, for example by provoking a patriotic response in the south German states and overcoming particularist resistance.
• Explains how the war strengthened Bismarck’s position, for example by allowing him to control diplomacy, isolate France, and present himself as the architect of victory.
• Explains how the war led to the creation of a German Empire, for example through the proclamation at Versailles in January 1871 and the acceptance of Wilhelm I as Kaiser.
• Explains the significance of the Treaty of Frankfurt 1871, for example the cession of Alsace-Lorraine, the payment of an indemnity, and the confirmation of German unification.
• Links the three outcomes together, showing how military victory, political leadership and territorial settlement reinforced each other.

Common mistakes and how to put them right

• Treating the war as only a military event and ignoring its political consequences.

  Put it right: Explain how it changed nationalist sentiment, Bismarck’s authority and the creation of the Empire.

• Assuming the Treaty of Frankfurt simply ended the war without lasting significance.

  Put it right: Explain how its terms affected France, Germany and future relations.

• Confusing the proclamation of the German Empire with the Treaty of Frankfurt.

  Put it right: Distinguish the political creation of the Empire in January 1871 from the formal peace settlement in May 1871.

Exam tips

• Use the three outcomes as a structure: nationalism, Bismarck’s position, and the Empire, then add the Treaty of Frankfurt as the settlement that confirmed them.
• Support each point with specific evidence, such as the proclamation at Versailles or the terms of the Treaty of Frankfurt.
• Explain significance rather than just describing events: say why each outcome mattered for unification and for the future.
