IBDP History HL Paper 3 -Unification of Germany and Italy (1815–1871) - Study Notes- New Syllabus

Impact of the Congress System on Germany and Italy

📝 Introduction

• After Napoleon, the victorious powers sought security and a workable balance of power.
• The settlement preserved separate German and Italian states, with Austria occupying a commanding position.
• Peace among great powers did not mean acceptance of national self-government.

🏛️ Vienna and the Territorial Settlement

The 1815 settlement established a German Confederation of 39 states, replacing Napoleon’s arrangements without creating a united Germany. Austria chaired its Federal Diet at Frankfurt; Prussia gained important western territories but could not direct the confederation alone. On the Italian peninsula Austria ruled Lombardy and Venetia and exercised influence over other dynasties. Piedmont-Sardinia expanded through Genoa as a potential buffer against France.

Legitimacy and the balance of power mattered more to negotiators than the wishes of nationalist activists. The settlements offered governments security but frustrated campaigners for popular sovereignty.

🤝 Metternich, Alliance and Intervention

Metternich defended the Habsburg position and opposed constitutional and national movements that might threaten a multinational empire. The Holy Alliance gave conservative monarchs a language of cooperation; the wider Congress System offered consultation, although the powers disagreed over intervention. Austria suppressed uprisings in Naples and Piedmont in 1821.

In Germany the Carlsbad Decrees of 1819 imposed censorship and oversight of universities following nationalist agitation. These measures slowed open organization, but policing ideas could not erase them. The Congress System’s effectiveness depended on cooperation between great powers, which became harder as their interests diverged.

⚖️ Historical Assessment

Austria and Metternich secured short-term order, especially in the Italian states, and created institutional barriers to unification. Yet Prussian strength grew within the German settlement, while repression gave constitutional and national demands a shared target. Distinguish an effective restoration in the 1810s and 1820s from its inability to prevent later change.

⚡ Quick Recap
✔ Vienna preserved a divided Germany and Italy.
✔ Austria dominated Lombardy-Venetia and the German Diet.
✔ Metternich backed censorship and intervention.
✔ Stability postponed national change but did not remove its causes.

Growth of nationalism and liberalism in Italy (1815–1848)

📝 Introduction

• Italian nationalism developed through secret societies, intellectual programs and failed revolts.
• Liberal constitutional demands and national independence sometimes overlapped, but activists disagreed on a republic, federation or monarchy.
• Austrian power and regional differences restricted cooperation.

📚 Ideas and Early Revolts

The Carbonari and other secret societies opposed restored governments and demanded constitutions in Naples and Piedmont in 1820–1821. Austria helped suppress these movements. Further uprisings in 1830–1831 and attempted conspiracies into the 1840s exposed weak organization, limited mass support and the difficulty of coordinating states subject to differing rulers.

Literary memories of Rome and Renaissance Italy, wider Romantic nationalism, and resistance to foreign control supported a sense of common identity. These ideas were unevenly shared: local loyalties and social priorities remained powerful.

👥 Mazzini, Gioberti and the Papacy

Giuseppe Mazzini founded Young Italy in 1831, advocating a unified, independent republic based on popular mobilization. His attempted insurrections failed militarily, yet his writing and exile networks kept republican nationalism visible. Vincenzo Gioberti argued for an Italian confederation under papal leadership; this offered moderates a route to unity without Mazzini’s social and political revolution.

The election of Pius IX in 1846 briefly inspired reform hopes. Papal reluctance to wage national war against Catholic Austria in 1848 revealed the limits of a papal solution. Compare the long-term value of nationalist ideas with the immediate weakness of nationalist armies and alliances.

⚖️ Historical Assessment

Failed revolts exposed the weakness of liberal nationalists before 1848, but built networks and rival visions that later leaders had to address. Mazzini’s ideological influence exceeded his immediate military success; Gioberti’s proposal depended on a papacy whose political priorities did not match national revolution.

⚡ Quick Recap
✔ Nationalism had republican, monarchical and papal variants.
✔ Mazzini’s Young Italy kept the republican project alive.
✔ Gioberti proposed a papal confederation.
✔ Austrian intervention and limited mass support defeated early risings.

Growth of nationalism and liberalism in Germany (1815–1848)

📝 Introduction

• Romantic culture, constitutional debate and economic ties contributed to German nationalist thinking.
• The German Confederation remained a collection of monarchies and free cities; demands for rights did not guarantee agreement on a single German state.
• Prussia rose economically and strategically while Austria retained formal political leadership.

📖 National Culture and Vormärz Politics

Students, writers and professional groups discussed language, shared history and constitutional government. The Wartburg gathering of 1817 and Hambach Festival of 1832 show growing public nationalism, although the participants were a minority. Vormärz rulers guarded dynastic sovereignty; the Carlsbad Decrees and censorship restricted liberal organization, while uneven state constitutions left activists seeking representative rights.

Some nationalists envisaged a Germany including Habsburg lands, while others favored a smaller state led by Prussia. This unresolved question later divided constitutional nationalists.

💰 Prussia and the Zollverein

Prussia’s administration, western industries and growing transport network helped its influence. The Zollverein customs union, established in 1834, removed many internal tariff barriers among German states and facilitated trade without including Austria. Commercial integration made cooperation with Prussia attractive and weakened some economic reasons for fragmentation.

A customs union was not a unified parliament or army. Austria’s exclusion mattered, but political unification still required a solution to dynastic opposition, military power and the relationship between small states and Prussia.

⚖️ Historical Assessment

Nationalism before 1848 gained cultural and economic foundations but lacked a common political method. The Zollverein helped Prussian leadership and economic connection, whereas censorship limited mass mobilization. Explaining later unification requires linking these long-term changes to political conflict and military decisions after 1848.

⚡ Quick Recap
✔ Vormärz monarchs resisted liberal nationalism.
✔ Culture and public meetings spread national demands.
✔ The Zollverein promoted economic integration from 1834.
✔ Prussia’s rise did not itself settle the question of unification.

Impact of the 1848 revolutions in Germany and Italy

📝 Introduction

• Revolutionaries sought constitutions, civic rights and national change amid economic crisis.
• Middle-class liberals, intellectuals, workers and peasants had different priorities.
• Evaluate immediate political defeat against the longer survival of ideas and experience.

🏛️ Germany: Parliament and Restoration

In 1848 unrest forced rulers to concede reforms, and delegates gathered at the Frankfurt Parliament to draft a constitution for a German nation-state. Deputies disputed borders, social questions and whether Austria belonged. In 1849 Frederick William IV of Prussia refused the imperial crown offered by the assembly, and armed rulers recovered the initiative. Failure exposed the weakness of a parliament without a reliable army or agreement with monarchs.

The constitutional debate nevertheless developed national arguments and institutions that later rulers could adapt, even as many liberals learned that popular pressure alone would not overcome dynastic force.

🇮🇹 Italy: Defeat and Continuing Nationalism

Risings drove Austrian forces from parts of northern Italy for a time. Piedmont-Sardinia fought Austria but lost at Custoza in 1848 and Novara in 1849. The Roman Republic of 1849, defended by Garibaldi and associated with Mazzini, fell after French intervention restored the pope. Social divisions and the separate military interests of rulers prevented a unified revolutionary front.

Constitutions were often withdrawn, but Piedmont-Sardinia kept its Statuto, creating a constitutional base for later Italian leadership. Literature, memorials and exile politics sustained nationalist culture after military failure.

⚖️ Historical Assessment

Revolutionaries failed to create united nations in 1848–1849 because divisions, foreign intervention and the strength of monarchic armies outweighed their gains. Still, the survival of Piedmont’s constitution, the Frankfurt precedent and nationalist networks made the revolutions consequential beyond their immediate defeats.

⚡ Quick Recap
✔ Germany’s Frankfurt assembly lacked enforceable authority.
✔ Italian campaigns and the Roman Republic were defeated.
✔ Austria and France helped restore established power.
✔ Piedmont’s constitution and nationalist networks survived.

Unification of Italy (1849–1871)

📝 Introduction

• Italian unification combined the policy of Piedmont-Sardinia, popular campaigns and international war.
• Cavour and Garibaldi differed on strategy but each helped expand the new kingdom.
• Look at the uneven economic and social experience of annexation as well as the map.

🎩 Cavour, Diplomacy and the North

As Piedmont’s prime minister, Cavour developed railways and finances and pursued limited constitutional government. In the Crimean War he raised Piedmont’s diplomatic profile. His agreement with Napoleon III facilitated war against Austria in 1859; Lombardy was gained, while peace came sooner than Cavour hoped. Central Italian plebiscites extended Piedmont’s position, but these votes occurred in the context of diplomatic and military pressure.

Cavour used foreign help but could not command French priorities. Austria’s strength made outside support valuable; France’s protection of the pope also delayed the acquisition of Rome.

⚔️ Garibaldi, the South and Completion

In 1860 Garibaldi’s Expedition of the Thousand took Sicily and Naples. His volunteers and local discontent undermined Bourbon rule, but Garibaldi handed his conquests to Victor Emmanuel II, allowing proclamation of the Kingdom of Italy in 1861. Venetia followed through alliance with Prussia in 1866; French withdrawal during the Franco–Prussian War enabled Italian troops to take Rome in 1870. Rome became the capital in 1871.

Unification did not erase disparities between industrializing northern areas and a poorer southern countryside. Taxation, conscription, southern brigandage and unresolved papal opposition show that integration remained contested.

⚖️ Historical Assessment

Cavour was vital for diplomacy, institutions and northern expansion, while Garibaldi delivered the decisive southern campaign. Wars involving France and Prussia opened opportunities that neither man controlled. A strong assessment distinguishes political unification by 1871 from economic equality or national consent across all regions.

⚡ Quick Recap
✔ Cavour strengthened Piedmont and secured foreign assistance.
✔ Garibaldi conquered the south in 1860.
✔ France, Austria and Prussia shaped the pace of annexation.
✔ Political unity did not end north–south inequality.

Unification of Germany and the establishment of the German Empire (1849–1871)

📝 Introduction

• After 1848, Prussian power became the central path to German unity.
• Bismarck’s diplomacy depended on the reformed Prussian army and the mistakes or isolation of opponents.
• National support strengthened the result, although the empire was created under monarchic authority.

🏛️ Prussia, Bismarck and Army Reform

Prussian minister-president Otto von Bismarck took office in 1862 amid a budget conflict over army reform. Reorganization associated with Wilhelm I, Roon and Moltke improved mobilization, staff planning and the use of railways. Bismarck governed through the constitutional dispute while building state power; later victories helped secure liberal cooperation despite earlier opposition.

Earlier industrial growth and the Zollverein had supported Prussia’s resources. They made war more feasible but did not alone decide which state would lead Germany.

⚔️ Three Wars and the Decline of Austria

Prussia and Austria defeated Denmark in 1864 over Schleswig and Holstein. Disagreement over the duchies helped Bismarck isolate Austria before Prussia defeated it in 1866. The Peace of Prague excluded Austria from German affairs while avoiding its complete destruction; the North German Confederation followed in 1867.

Conflict with France in 1870–1871 drew southern German states alongside Prussia. German victories and the siege of Paris preceded the proclamation of the empire at Versailles in January 1871. Bismarck exploited national feeling and diplomacy, but French decisions, the southern states’ choices and Prussia’s battlefield success all mattered.

⚖️ Historical Assessment

Military reorganization and Prussian victory pushed Austria out of German politics; Bismarck coordinated the opportunities through alliances, limited war aims and statecraft. The 1871 empire united much of Germany while leaving Austria outside and locating ultimate authority in imperial and Prussian institutions rather than the Frankfurt liberals’ parliament.

⚡ Quick Recap
✔ Bismarck used diplomatic isolation and controlled war aims.
✔ Prussian military reforms improved battlefield capacity.
✔ Austria was excluded after 1866.
✔ Victory over France preceded imperial proclamation in 1871.
