How was Germany Unified? (1848–1871)

Hello Historians! This chapter is incredibly important. You are going to learn how a collection of 39 independent states—not much different from small villages run by different families—turned into one of the most powerful countries in Europe: modern Germany. This transformation was sudden, brutal, and completely changed the balance of power in the world. Ready? Let’s dive in!

Section 1: Germany Before Unification – The Scattered States

What was Germany like before 1871?

Imagine Europe in the mid-19th century. There was no single country called "Germany." Instead, there were 39 separate states, grouped loosely into the German Confederation. The two biggest and most important members were Austria and Prussia. They were constantly competing for influence over the smaller states.


Prerequisite Concept Check: Nationalism and Liberalism

The desire for unification was fueled by two major ideas:

1. Nationalism: The belief that people who share a common language (German), culture, and history should live under one government in a single, independent nation-state.
2. Liberalism: The desire for political freedoms, constitutions, and democratic participation (moving away from absolute monarchs).

The Key Economic Step: The Zollverein

Unification didn't start with soldiers; it started with money!

The Zollverein (meaning 'Customs Union'), established in 1834, was a hugely important step towards unity, even if it wasn't political yet.

What was the Zollverein?

  • It was a trade agreement that removed tariffs (taxes on imported goods) between most of the German states.
  • Analogy: Think of it like a giant, unified shopping zone. Before, if you moved goods from State A to State B, you paid a tax. With the Zollverein, trade was free and easy, making everyone richer.
  • Who was excluded? Austria. This gave Prussia massive economic power and influence over the other German states.

Key Takeaway: Before 1871, Germany was divided. Economic unity (Zollverein, led by Prussia) came long before political unity.

Section 2: The Failed Attempt – 1848 Revolution

The spirit of nationalism and liberalism led to chaos across Europe in 1848. In Germany, people revolted, demanding liberal governments and, crucially, unification.


The Frankfurt Parliament (1848–1849)

The revolution led to the gathering of the Frankfurt Parliament—an assembly of liberals, intellectuals, and middle-class representatives from across the German states.

Why did they fail to unify Germany?

1. Too much talk, not enough action: The Parliament spent too much time debating the perfect constitution instead of organizing military power or seizing control.

2. The Grossdeutsch vs. Kleindeutsch Debate: They couldn't agree on whether the new unified Germany should include the Austrian Empire (Grossdeutsch - Greater Germany) or exclude Austria and be dominated by Prussia (Kleindeutsch - Smaller Germany).

3. The King’s Rejection: They eventually offered the crown of a unified Germany to King Frederick William IV of Prussia. He rejected it, famously saying he wouldn't accept "a crown from the gutter." He believed monarchs should rule by Divine Right, not by the will of the people.

After 1849, the conservative forces (the monarchs and Austria) regained control, and the idea of peaceful, liberal unification was crushed. Austrian influence was formally re-established in 1850, ensuring the division remained.

Did you know? This failure taught German nationalists a critical lesson: unity would not come through speeches and voting; it would come through power and military force.

Key Takeaway: The 1848 revolutions failed because liberals lacked power and the Prussian King refused the crown. Austria remained the dominant conservative power.

Section 3: The Architect of Unity – Otto von Bismarck

The stage was set for the man who would finally unify Germany: Otto von Bismarck.

Bismarck as Prussian Minister-President

In 1862, King Wilhelm I appointed Bismarck as Minister-President of Prussia (the most powerful political position below the King).

Bismarck was a conservative aristocrat (a Junker) who despised liberalism and democracy, but he was fiercely loyal to Prussia and believed passionately in German unity under Prussian leadership.

His strategy was simple and brutal:

1. Realpolitik: The "Reality" Policy

Bismarck used Realpolitik, meaning he based his decisions on practical results rather than moral or ideological concerns. He would make alliances with enemies and betray friends if it served Prussia’s goal.

Analogy: Imagine a ruthless chess player who is willing to sacrifice any piece, even the Queen, if it leads directly to checkmate.

2. "Blood and Iron"

In 1862, Bismarck famously stated: "The great questions of the time will not be decided by speeches and majority resolutions—that was the great mistake of 1848 and 1849—but by iron and blood."

This meant unification would only be achieved through war and military power (blood) supplied by industry and a strong economy (iron).

Key Takeaway: Bismarck, a conservative, was appointed to strengthen Prussia. He ignored liberal wishes and planned to unify Germany through deliberate military conflict (Blood and Iron).

Section 4: The Three Wars of Unification (1864–1871)

Bismarck used foreign policy and deliberate wars to eliminate obstacles to Prussian dominance, bringing the southern German states into alignment.

War 1: The Danish War (1864) – Schleswig-Holstein

The Issue: The provinces of Schleswig and Holstein were inhabited by both Germans and Danes, and Denmark claimed them.

Bismarck's Move: Bismarck persuaded Austria to join Prussia in a quick war against Denmark. They won easily.

The Consequence: The provinces were taken from Denmark. Prussia took control of Schleswig, and Austria took control of Holstein. This joint administration immediately created a perfect excuse for Bismarck to pick a fight with Austria later.

War 2: The Austro-Prussian War (1866) – Eliminating Austria

Bismarck needed to remove Austria from German affairs permanently.


Step-by-Step Breakdown:

1. Preparation: Bismarck secured neutrality from France and Italy, ensuring Austria would fight alone.

2. The Provocation: Prussia manufactured a dispute over the administration of Schleswig-Holstein.

3. The War: The war lasted just seven weeks (the "Seven Weeks’ War"). The Prussian army, modernized and using superior railways and technology (like the needle gun), crushed the Austrians at the Battle of Königgrätz (Sadowa).

4. Consequences:

  • Austria was completely excluded from German affairs.
  • The old German Confederation was dissolved.
  • Prussia annexed several northern states.
  • Bismarck created the North German Confederation (NGC), a state controlled entirely by Prussia. The Southern German states remained independent but were secretly allied with Prussia.
War 3: The Franco-Prussian War (1870–1871) – Bringing the South In

The only remaining obstacle was France, led by Emperor Napoleon III. France feared a strong, unified Germany on its border and had to be defeated to secure the loyalty of the Southern German states (who were Catholic and less inclined to join Protestant Prussia).


Step-by-Step Breakdown:

1. The Spanish Succession Crisis: A German candidate (Prince Leopold) was offered the Spanish throne. France strongly objected.

2. The Ems Telegram: Following a meeting between King Wilhelm I and the French ambassador at Ems, Bismarck received a telegram describing the conversation. Bismarck deliberately edited the telegram to make it sound as though the Prussian King had rudely insulted the French ambassador.

Analogy: If a text message says, "I cannot agree to your demand," Bismarck changes it to, "Go away, you fool!"

3. Declaration of War: Napoleon III felt publicly humiliated and declared war on Prussia (July 1870).

4. The War: The Southern German states, feeling threatened by French aggression, honored their secret alliances and joined Prussia. The combined German forces were highly effective and defeated the French at the Battle of Sedan, capturing Napoleon III himself.

Key Takeaway: Bismarck deliberately used three short, successful wars to eliminate rivals (Denmark, Austria) and bait the final opponent (France), completing military unification.

Section 5: The Creation of the German Empire (1871)

The defeat of France secured the loyalty and cooperation of all German states, North and South.

The Final Act

On 18 January 1871, while German armies were still occupying France, the leaders of the German states gathered in the Hall of Mirrors at the Palace of Versailles (a deeply symbolic and humiliating location for the defeated French).

There, King Wilhelm I of Prussia was proclaimed Kaiser (Emperor) of the new unified German Empire.

Consequences of Unification:

  • A new major power instantly emerged in Central Europe.
  • France lost the provinces of Alsace and Lorraine and was forced to pay a massive indemnity (a fine), fostering long-term French bitterness and a desire for revenge.
  • Bismarck became the first Chancellor (chief minister) of the new Empire, cementing his reputation as the "Iron Chancellor."

Quick Review: Bismarck's Responsibility

How far was Bismarck responsible for the unification of Germany?

Yes (He was responsible):
- He applied Realpolitik to manipulate events (Ems Telegram, Schleswig-Holstein dispute).
- He successfully built up the Prussian army and implemented "Blood and Iron."
- He successfully isolated his enemies (Austria, France) before attacking.


No (Other factors mattered):
- Pre-existing German nationalism made unity popular.
- The Zollverein had already created economic unity.
- The Prussian military (Generals von Moltke and von Roon) was highly effective and modernized.


Don't forget this key point: Bismarck did not create unity out of nothing. He took existing elements—nationalism, economic power, and military strength—and ruthlessly engineered the final political outcome.
