The Unification of Italy & Germany

1848: the failed springtime

In 1848, a wave of liberal and nationalist revolutions swept nearly every European capital, demanding constitutions, civil rights, and national unity or independence. In France they toppled the monarchy; in the German and Italian states and the Austrian Empire, revolutionaries sought unity and reform. But the revolutions almost all failed by 1849: liberals and radicals split, nationalist groups clashed, and conservative armies restored order. The great lesson drawn from 1848 was that unification and reform would not come from popular idealism alone — it would have to be achieved by powerful states using force and cunning, an approach called realpolitik.

The unification of Italy

Italy was unified through the leadership of the northern kingdom of Piedmont-Sardinia. Its prime minister, Count Camillo di Cavour, a master of realpolitik, modernized Piedmont and used shrewd diplomacy — allying with France to expel Austria from northern Italy. Meanwhile the romantic nationalist Giuseppe Garibaldi led his volunteer "Red Shirts" to conquer the south (Sicily and Naples), then handed it over to Piedmont’s king. By 1861 most of the peninsula was united as the Kingdom of Italy under Victor Emmanuel II, with Rome added in 1870. Unification was driven from above by diplomacy and war more than by mass revolution.

The unification of Germany

Germany was united by Prussia under its chancellor Otto von Bismarck, the supreme practitioner of realpolitik, who declared that the great questions would be decided not by speeches but by "blood and iron." Bismarck engineered three wars to rally German states around Prussia and exclude Austria: against Denmark (1864), Austria (1866), and finally France (the Franco-Prussian War, 1870–71). Victory over France completed unification: the German Empire was proclaimed in 1871 in the Hall of Mirrors at Versailles, with the Prussian king as Kaiser Wilhelm I. A powerful, industrial, unified Germany now dominated central Europe, decisively upsetting the balance of power.

Tip

Both unifications share a formula: realpolitik (power politics over idealism) driven by a strong state (Piedmont/Prussia) and a statesman (Cavour/Bismarck) using diplomacy and war. Contrast this with the failed idealistic, bottom-up revolutions of 1848.

Worked example

Briefly explain the strategy Bismarck used to unify Germany, and describe how a unified Germany affected the European balance of power.

  1. 1.Identify the leader and approach: Bismarck, chancellor of Prussia, pursued unification through realpolitik — "blood and iron" rather than liberal idealism.
  2. 2.Describe the method: he provoked and won three wars, against Denmark (1864), Austria (1866), and France (1870–71), to unite the German states under Prussian leadership and exclude Austria.
  3. 3.State the result: the German Empire was proclaimed in 1871 with the Prussian king as Kaiser.
  4. 4.Explain the balance-of-power impact: a large, industrial, militarily powerful Germany in the center of Europe overturned the old balance and alarmed neighbors, especially France.
Answer: Bismarck unified Germany through realpolitik — "blood and iron" — engineering three successful wars against Denmark, Austria, and France that rallied the German states around Prussia and excluded Austria, producing the German Empire in 1871. A unified, industrial, and militarily strong Germany at the heart of Europe upset the balance of power, alarming rivals (notably a defeated France) and helping set the stage for later great-power tensions.
Checkpoint

The revolutions of 1848 are generally considered significant because they:

Watch out

Italian and German unification were driven from above — by Piedmont and Prussia through diplomacy and war — not by the failed grassroots revolutions of 1848. Crediting "the people" alone misreads how realpolitik actually achieved unity.

Checkpoint

Bismarck’s phrase that the great questions of the day would be decided by "blood and iron" best expresses the principle of:

On the exam

End the unit by pointing forward: the creation of a powerful unified Germany in 1871 reshaped the balance of power and generated the great-power rivalries and alliance systems that would help ignite World War I — the subject of Unit 8.
