On September 30, 1862, the new minister-president of Prussia stood before a hostile budget committee of the Prussian parliament, which was refusing to fund the army the king wanted. Otto von Bismarck brushed their objections aside with words that would define an age:
"Not by speeches and majority resolutions are the great questions of the day decided — that was the great mistake of 1848 and 1849 — but by iron and blood."
Fourteen years earlier, in 1848, idealistic liberals and nationalists across Europe had tried to build new nations on speeches, constitutions, and majority votes. They had failed almost everywhere (Lesson 12). Bismarck's message was brutal and clear: nations would not be talked into existence: they would be forged — by armies, war, and cold calculation. Within a decade he would prove it, welding two dozen German states into an empire through three deliberate wars. In Italy, others were learning the same lesson. This lesson is about how the dream of the nation finally became hard political fact — and at what cost.
The revolutions of 1848 (Lesson 12) were the high tide of romantic nationalism — the belief that peoples sharing a language, culture, and history ought to govern themselves in a single nation-state. Across the German states and the Italian peninsula, liberal nationalists drafted constitutions and proclaimed unity. By 1849 nearly all of it had collapsed. The Frankfurt Parliament in Germany debated for a year and then dissolved in failure; in Italy, Austrian armies crushed the revolts and restored the old order.
The men who finally achieved unification drew a ruthless conclusion: unity would come not from idealism but from power, diplomacy, and war. This is Realpolitik — politics based on practical realities and self-interest rather than moral or ideological principle. The architects of unification, Camillo di Cavour in Italy and Otto von Bismarck in Germany, were conservatives who used nationalism as a tool to strengthen their own states, not romantic dreamers.
Connections (backward): The borders these men tore up had been drawn at the Congress of Vienna (1815) by Metternich (Lesson 11), who designed a fragmented Italy and a loose German Confederation precisely to keep both regions weak and Austria dominant. Unification was the demolition of Metternich's Europe.
In 1815 "Italy" was, in Metternich's famous phrase, merely "a geographical expression" — a patchwork of states: the Kingdom of Piedmont-Sardinia in the northwest, Austrian-controlled Lombardy and Venetia in the north, several central duchies, the Papal States ruled by the pope, and the Kingdom of the Two Sicilies (Naples and Sicily) in the south. The movement to unify them is called the Risorgimento ("resurgence").
Three very different men drove it:
Cavour understood Piedmont could never defeat Austria alone, so he found a great-power ally. At a secret meeting at Plombières (July 1858), he struck a deal with Napoleon III of France: France would help Piedmont drive Austria out of northern Italy, in exchange for the territories of Nice and Savoy. Cavour then provoked Austria into declaring war in 1859 (the Second War of Italian Independence). Franco-Piedmontese armies won bloody victories at Magenta and Solferino, and Piedmont gained Lombardy — but Napoleon III, alarmed by the carnage and by Prussian mobilization, abruptly made a separate peace, leaving Venetia still in Austrian hands. Even so, the central Italian duchies voted to join Piedmont.
Then the initiative passed to Garibaldi. In May 1860, with about a thousand red-shirted volunteers — the "Thousand" (i Mille), the Redshirts — he sailed from Genoa and landed in Sicily, toppling the Kingdom of the Two Sicilies in a lightning campaign, then crossed to the mainland and took Naples. Garibaldi, a republican at heart, might have marched on Rome — but in a decisive moment he handed his conquests over to Cavour's king, Victor Emmanuel II of Piedmont, placing national unity above his own ideals.
In March 1861, the Kingdom of Italy was proclaimed, with Victor Emmanuel II as king. Unification was not yet complete: Venetia was added in 1866 (as a reward for allying with Prussia against Austria) and Rome in 1870 (when French troops protecting the pope withdrew during the Franco-Prussian War). Rome then became the capital.
Connections (theme — state-building): Note who was left out of power. Unification was achieved "from above," by Piedmont's monarchy and army, not by Mazzini's democratic republic or Garibaldi's radicals. The new Italy was a constitutional monarchy dominated by the propertied north — leaving a deep north-south divide and a population that, in the words attributed to the statesman Massimo d'Azeglio, still had to be turned from Italians-on-paper into Italians-in-fact.
Germany in 1815 was the German Confederation, a loose league of 39 states dominated by Austria, with Prussia the rising rival. Economic unity came first: the Prussian-led Zollverein (customs union, from 1834) knit the German economies together — without Austria — long before political unity.
The decisive figure was Otto von Bismarck (1815–1898), a Junker (Prussian land-owning noble) appointed minister-president of Prussia in September 1862 by King Wilhelm I to break a deadlock: parliament was refusing to fund an army reform. Bismarck simply collected the taxes and built the army anyway, scorning the liberals with his "iron and blood" speech. A master of Realpolitik, he would unify Germany under Prussian leadership through three carefully engineered wars.
Connections (forward — and a warning): The war's terms planted a time bomb. By the Treaty of Frankfurt (1871), France lost the provinces of Alsace and Lorraine to Germany and paid a huge indemnity. French desire for revanche (revenge) over Alsace-Lorraine would poison Franco-German relations for half a century — a direct line toward the First World War.
In the Hall of Mirrors at the Palace of Versailles — on French soil, a calculated humiliation — the German Empire (the Second Reich) was proclaimed on January 18, 1871, with Wilhelm I as Kaiser (emperor) and Bismarck as chancellor. For the first time in history, a powerful, unified German nation-state sat in the heart of Europe.
Connections (theme — balance of power → the road to WWI): This is one of the most consequential events in modern European history. The unified Germany was instantly the strongest land power on the Continent — populous, industrializing fast, and militarily dominant. It shattered the balance of power that Vienna had maintained since 1815. A bitter France, a displaced Austria, and a nervous Europe now had to live alongside this new colossus. The alliance systems, arms races, and rivalries that Bismarck spent the next twenty years managing — and that his successors mishandled — would erupt in 1914 (Lesson 19). German unification did not cause World War I, but it reset the board on which the war would be played.

"Prussia must concentrate and maintain its power for the favorable moment, which has already slipped by several times. Prussia's boundaries according to the Vienna treaties are not favorable to a healthy state life. The great questions of the day will not be decided by speeches and majority resolutions — that was the great mistake of 1848 and 1849 — but by iron and blood."
HAPPY analysis: - Historical context: Delivered in 1862, in the middle of a constitutional crisis: the liberal Prussian parliament was blocking the army budget. Just thirteen years earlier, the liberal-nationalist revolutions of 1848–49 had failed. - Audience: The immediate audience was the budget committee — hostile liberal deputies he needed to overrule. The wider audience was the Prussian and German public. - Purpose: To justify governing without parliamentary consent and to assert that military strength, not parliamentary debate, would solve "the German question." - Point of view: Bismarck was a conservative Junker contemptuous of liberalism and parliamentary government; he saw the state's strength, not popular will, as the engine of history. - whY it matters: The line became the slogan of Realpolitik and the epitaph for the idealism of 1848. Sourcing note: Bismarck actually said "iron and blood" (Eisen und Blut); the familiar inversion "blood and iron" (Blut und Eisen) spread later through the press. A sourcing-savvy reader also weighs his intent — this was a deliberate provocation aimed at cowing his opponents, not a neutral statement of policy.
Why did unification succeed in the 1860s after failing in 1848? In 1848 nationalism was driven from below by liberal idealists who relied on debate, constitutions, and popular assemblies — and who lacked armies, great-power allies, and a willingness to use force. The Frankfurt Parliament could not even agree on borders, let alone command troops. By the 1860s, unification was driven from above by powerful states (Piedmont, Prussia) led by conservative practitioners of Realpolitik who commanded modern armies, industrial economies, and shrewd diplomacy. The difference was power and method, not desire.
Compare — Italian and German unification. The parallels are striking, which is exactly why the AP exam loves this comparison:
| Italy | Germany | |
|---|---|---|
| Lead state | Piedmont-Sardinia | Prussia |
| "Diplomat" architect | Cavour | Bismarck |
| Monarch unified under | Victor Emmanuel II | Wilhelm I |
| Excluded rival power | Austria | Austria |
| Key foreign ally/foe | allied with France (1859) | defeated France (1870–71) |
| Completed | 1861 (Rome 1870) | 1871 |
Both were achieved "from above" by conservative diplomats wielding war and diplomacy, both expelled Austria, both produced constitutional monarchies dominated by the strongest state. The differences: Italian unification depended on a popular-revolutionary wildcard (Garibaldi) and on French help, and it left a weaker, divided new state; German unification was more thoroughly state-directed by Bismarck and produced a far stronger, more militarized empire. Bismarck managed nationalism with surgical precision; Cavour had to improvise around Garibaldi's freelancing.
Mazzini vs. Cavour vs. Garibaldi — idealist, diplomat, soldier. The single most-tested distinction in this lesson. Mazzini = the romantic idealist (Young Italy, a democratic republic) whose methods failed. Cavour = the pragmatic diplomat (prime minister of Piedmont, Realpolitik, foreign alliances). Garibaldi = the soldier (the Thousand/Redshirts, who conquered Sicily and Naples and handed them to the king). Idealist → diplomat → soldier.
The three German wars, in order. Keep the sequence and the enemy straight: 1864 Denmark (Schleswig-Holstein), 1866 Austria (Seven Weeks' War, excludes Austria, creates the North German Confederation), 1870–71 France (Franco-Prussian War, rallies the south, creates the Empire). A useful mnemonic: the enemies get bigger each time — Denmark, Austria, France.
"Blood and iron" vs. 1848 liberalism. Bismarck's whole point was that he rejected the methods of 1848. Do not describe German unification as a triumph of liberal nationalism: it was a conservative, monarchical, military project that defeated and absorbed the liberal-national movement. Unification was achieved despite, not because of, the liberals.
Two different "Napoleons." The French ally/foe here is Napoleon III (Louis-Napoleon, emperor 1852–1870), nephew of the Napoleon I of Lessons 11. He helped Cavour in 1859 and was captured at Sedan in 1870.
Who unified under whom. Italy unified under Victor Emmanuel II (king); Germany under Wilhelm I (Kaiser). Bismarck and Cavour were the chancellor/prime-minister architects, never the monarchs.
1. B — Realpolitik is politics grounded in practical power and self-interest, not romantic ideals (A) or moral principle. Both Cavour and Bismarck were conservatives who used nationalism instrumentally.
2. C — The decisive change was method: unification came from above, led by powerful states (Piedmont, Prussia) with armies and diplomacy, after the bottom-up idealism of 1848 had failed. Austria did not withdraw voluntarily (B) — it was defeated.
3. B — Mazzini, founder of Young Italy (1831), was the romantic idealist seeking a democratic republic. (A) is Cavour, (C) is Garibaldi, (D) is Victor Emmanuel II.
4. C — At Plombières (1858), Cavour promised France Nice and Savoy in exchange for help against Austria. Lombardy and Venetia (A) were the Austrian-held targets, not the payment.
5. B — Garibaldi led the Thousand (Redshirts) to conquer Sicily and Naples (1860) and then handed them to Victor Emmanuel II, choosing national unity over his own republicanism. The French alliance (A) was Cavour's work; the Zollverein (D) was German.
6. C — The order is Denmark (1864) → Austria (1866) → France (1870–71). The enemies grow larger each time.
7. B — The 1866 war excluded Austria from German affairs and produced the North German Confederation (1867). The Empire (A) and Alsace-Lorraine (C) came with the 1870–71 war.
8. B — Bismarck edited the Ems Dispatch to provoke France into war, the patriotic conflict he needed to draw the southern states into unity. The budget crisis (D) was 1862.
9. C — The Empire was proclaimed in the Hall of Mirrors at Versailles, January 18, 1871 — on French soil, a deliberate humiliation.
Stimulus for Questions 10–11. Read the excerpt.
"The great questions of the day will not be decided by speeches and majority resolutions — that was the great mistake of 1848 and 1849 — but by iron and blood." — Otto von Bismarck, speech to the Prussian budget committee, 1862 [authentic; standard translation — verify wording]
10. B — "The great mistake of 1848 and 1849" refers to the liberal nationalists who tried to build unity through speeches and parliamentary votes (e.g., the Frankfurt Parliament) and failed.
11. B — The quote is classic evidence of the conservative, militarized Realpolitik behind German unification — the opposite of liberal constitutionalism (A).
Stimulus for Questions 12–13. Study the description of a historical map.
Map: The Unification of Germany, 1866–1871. The map shades Prussia in 1862 stretching across northern Germany. A second shade shows the states added to form the North German Confederation in 1867 (the states north of the Main River). A third shade shows the southern states — Bavaria, Württemberg, Baden, and Hesse-Darmstadt — joining in 1871 to complete the German Empire. An inset highlights Alsace and Lorraine, transferred from France to Germany in 1871.
12. B — The northern states unified in 1867; the Catholic southern states (Bavaria, Württemberg, Baden, Hesse-Darmstadt) joined only in 1871, after the Franco-Prussian War rallied German patriotism against France.
13. B — The loss of Alsace and Lorraine created a lasting French desire for revenge (revanche), straining Franco-German relations on the road to 1914. It was imposed by the Treaty of Frankfurt, not reversed by it (D).
14. B — Unlike Germany's tightly state-directed unification, Italy's depended partly on the popular-revolutionary Garibaldi and on French military help (1859). Both unifications excluded Austria and produced monarchies, so (C) and (D) are not distinctive to Italy; (A) is false.
15. B — Unification created a powerful new state at the center of Europe that upset the balance of power Vienna had maintained since 1815 and reshaped the rivalries leading toward World War I.
About this SAQ. A Short-Answer Question gives you a stimulus and asks for three brief, specific tasks (a), (b), (c). You do not write a thesis or an essay — you answer each part in 1–3 sentences with concrete evidence. Each part is worth 1 point (3 total). This SAQ is a primary-source type (the kind that appears as SAQ 2 on the exam).
"The great questions of the day will not be decided by speeches and majority resolutions — that was the great mistake of 1848 and 1849 — but by iron and blood." — Otto von Bismarck, speech to the Prussian budget committee, September 1862 [authentic; standard translation — verify wording]
Using the passage, respond to parts (a), (b), and (c).
(a) Identify the political method or philosophy Bismarck advocates in the passage.
(b) Explain how that method was used to achieve German unification between 1864 and 1871.
(c) Explain ONE consequence of German unification for the European balance of power.
(a) Bismarck advocates Realpolitik — the use of practical power, especially military force ("iron and blood"), rather than liberal debate, speeches, or majority votes, to achieve political goals such as national unification.
(b) Bismarck applied this method through three deliberate wars that united Germany under Prussian leadership: the war against Denmark (1864) over Schleswig-Holstein, the Austro-Prussian War (1866), which excluded Austria and created the North German Confederation, and the Franco-Prussian War (1870–71), which rallied the southern German states and led to the proclamation of the German Empire at Versailles in 1871 — unity achieved by armies and war, exactly as the passage prescribes.
(c) German unification created a powerful new state at the center of Europe that overturned the balance of power established at the Congress of Vienna in 1815. (Acceptable alternatives: France's loss of Alsace-Lorraine produced a lasting desire for revenge that worsened Franco-German relations; the new German Empire's military and industrial strength fueled the alliance systems and rivalries that contributed to the outbreak of World War I in 1914.)
| Part | Earns the point when the response… | Worth |
|---|---|---|
| (a) Identify | Names the method/philosophy — Realpolitik, or "power/force over debate," or "rule by iron and blood / military strength" | 1 pt |
| (b) Explain | Goes beyond naming to show how the method produced unification, with at least one specific, accurate piece of evidence (e.g., one of the three wars by name and outcome) | 1 pt |
| (c) Explain | States one specific consequence for the balance of power and explains the link (not just naming an event) | 1 pt |
"Identify" vs. "Explain." Part (a) only asks you to name something — one accurate sentence is enough; do not over-write it. Parts (b) and (c) say explain, which requires evidence plus reasoning that connects the evidence to the prompt.
