Chapter 20: The Age of Ideologies
1. The Search for Order in Europe, 1815–1830
Aftermath of the Napoleonic Wars
Napoleon’s defeat in 1815 left Europe politically unstable with fears of revolution and renewed conflict.
The Congress of Vienna (1814–1815) sought to restore monarchies, redraw borders, and prevent any one nation from dominating Europe.
Key Goals of the Congress
Balance of Power — prevent dominance of a single nation (e.g., Britain balancing France, Austria balancing Prussia).
Legitimacy — restore hereditary monarchs who were deposed during the Napoleonic era.
Collective Security — great powers pledged to suppress revolutions.
The Concert of Europe
Alliance system (Austria, Britain, Russia, Prussia, later France) meeting periodically to resolve disputes and maintain stability.
Used military intervention to crush uprisings (Spain 1820, Naples 1821).
Metternich’s Conservatism
Klemens von Metternich promoted traditional monarchy, church authority, and aristocracy as the foundation of social order.
He strongly opposed liberalism, nationalism, and democracy.
Suppression of Liberal and Nationalist Movements
Secret police, censorship, and banning political clubs were common.
Example: Carlsbad Decrees (German Confederation, 1819) suppressed university reforms and press freedom.
2. Citizenship and Sovereignty, 1830–1848
Shifting Ideas of Political Participation
Liberalism promoted constitutional government, property-based voting rights, and individual freedoms.
Nationalism demanded unity of people with a shared language, culture, and history.
Revolutions of 1830
France: July Revolution overthrew King Charles X; Louis-Philippe became the “Citizen King.”
Belgium: Won independence from the Netherlands.
Poland: Uprising crushed by Russia.
1848 Revolutions
Swept across Europe (France, German states, Italy, Austria-Hungary).
Common goals: universal male suffrage, national unification, constitutional rights.
Mostly failed, but planted seeds for later reforms.
Expansion of “Citizenship”
Growing push for voting rights, freedom of the press, and broader political participation beyond elites.
Working-class and women’s demands began influencing political debates.
3. Revolutions, Migration, and Political Refugees
Revolutionary Failures → Migration
Many revolutionaries fled after suppression, especially in 1848.
Political refugees carried radical ideas abroad, influencing politics in host countries.
“Forty-Eighters” in the United States
German revolutionaries settled in the Midwest; became active in journalism, education, and anti-slavery causes.
Impact on Host Nations
Spread of liberal, socialist, and nationalist thought.
Cultural enrichment through skills, language, and ideas.
4. The Politics of Slavery after 1815
Global Abolition Movement
Britain banned the slave trade in 1807; slavery abolished in British colonies in 1833.
Abolitionists like William Wilberforce (Britain) and Frederick Douglass (US) pushed for a global end to slavery.
Persistence of Slavery
Continued in US South, Brazil, and Cuba due to plantation profitability.
Atlantic slave trade diminished but illegal trafficking persisted.
International Diplomacy
Britain pressured other nations to sign treaties banning the trade; Royal Navy patrolled to intercept slave ships.
Slavery as Political Flashpoint
In the US, debates over slavery intensified toward the Civil War.
In Europe, slavery’s morality tied to broader liberal and humanitarian ideals.
5. Taking Sides: New Ideologies in Politics
Conservatism — Defended monarchy, aristocracy, and established religion; feared chaos from revolutionary change.
Liberalism — Advocated civil liberties, parliamentary government, and economic freedom (free trade).
Nationalism — Sought self-determination for cultural-linguistic groups.
Socialism — Early forms (Fourier, Owen) emphasized cooperative communities; later Marx and Engels pushed revolutionary class struggle.
Anarchism — Advocated abolition of all government; Mikhail Bakunin argued for voluntary cooperation.
Feminism — Pioneers like Mary Wollstonecraft and early suffragists argued for women’s rights in education, work, and politics.
6. Cultural Revolt: Romanticism
Reaction Against Enlightenment Rationalism — Valued emotion, nature, imagination, and individualism.
Art & Literature — Delacroix celebrated dramatic historical scenes and nature; Hugo and Brontë sisters explored emotion and individuality.
Music — Beethoven, Chopin, Liszt emphasized emotional power.
Nationalist Romanticism — Folk tales, music, and history built national pride (e.g., Grimm Brothers).
7. Conclusion
Post-1815 Europe featured a tug-of-war between conservative monarchies and revolutionary ideas.
Ideologies like liberalism, nationalism, and socialism challenged traditional authority.
Romanticism expressed cultural resistance to industrial and political conformity.
8. (Implicit Topic) The Age of Ideologies as a Turning Point
This era introduced modern political ideologies that still shape politics today.
Revolutions failed but ideas persisted, reemerging stronger in later decades.
Set the stage for national unifications and imperial rivalries in the late 19th century.
Chapter 21: Revolutions and Nation Building, 1848–1871
1. The Revolutions of 1848
Background Causes
Economic hardship: food shortages (Irish Potato Famine) and unemployment from industrial downturns.
Political frustration: middle classes demanded constitutional rights; workers demanded higher wages and conditions; nationalists sought self-determination.
Inspiration: previous revolutions (1789, 1830) and rising socialist/Marxist thought.
Key Uprisings
France: February Revolution toppled Louis-Philippe; Second Republic established with universal male suffrage; June Days exposed class divisions; Louis-Napoleon Bonaparte elected president in December.
German States: Frankfurt Assembly attempted German unification under a liberal constitution; failed when the Prussian king refused the crown.
Austria-Hungary: Vienna and Hungary revolts demanded constitutional government and autonomy; crushed by Austrian and Russian forces.
Italy: Revolts across states sought unification and independence from Austria; suppressed by 1849.
Reasons for Failure
Divisions between liberals and radicals; divisions among nationalists of different ethnic groups.
Conservative military power remained strong.
Monarchs exploited divisions to regain control.
Legacy
Immediate failure but long-term influence: many demands (constitutionalism, nationalism) re-emerged in later decades.
2. Building the Nation-State
Nationalism as a Unifying Force
Shift from revolutionary ideal to conservative tool; leaders used nationalism to strengthen monarchies and unite people under centralized states.
Italian Unification (Risorgimento)
Leaders: Count Camillo di Cavour (Piedmont-Sardinia PM) used diplomacy and alliances; Giuseppe Garibaldi led military campaigns with the “Red Shirts.”
1861: Kingdom of Italy proclaimed under King Victor Emmanuel II.
1870: Rome annexed, completing unification.
German Unification
Driven by Otto von Bismarck (Prussia’s PM) using “blood and iron” (war and industry).
Wars: Danish War (1864) — with Austria to seize Schleswig and Holstein; Austro-Prussian War (1866) — Prussia defeated Austria; created the North German Confederation.
Franco-Prussian War (1870–1871) — victory over France rallied southern German states to join unification.

3. Nation and State Building in Russia and the United States
Russia
Tsar Alexander II implemented reforms after defeat in the Crimean War (1853–1856).
Emancipation of Serfs (1861) gave peasants limited land rights but left many in poverty.
Industrialization began slowly; revolutionary movements emerged, including populists and early Marxists.
United States
Sectional tensions over slavery escalated into the Civil War (1861–1865).
Union victory preserved national unity and abolished slavery (13th Amendment).
Reconstruction (1865–1877) aimed to rebuild the South and integrate freed African Americans into political life, though racial inequality persisted.
4. “Eastern Questions”: International Relations and the Decline of Ottoman Power
The Eastern Question — how to deal with a weakening Ottoman Empire without upsetting the balance of power.
Crimean War (1853–1856) — Russia sought influence; Britain and France allied with the Ottomans to block expansion. First modern war with railways, telegraphs, and war correspondents; Russia’s defeat highlighted modernization needs.
Balkan Nationalism — Serbs, Greeks, Bulgarians, and Romanians sought independence; movements sparked international crises as great powers took sides.
5. Conclusion
The mid-19th century was a turning point: nationalism became a tool for conservative state-building as well as revolutionary change.
Italy and Germany emerged as unified nations, altering the balance of power.
Russia and the United States underwent significant reforms and conflicts to define their futures.
The decline of the Ottoman Empire began reshaping geopolitics, especially in the Balkans.
Chapter 22: Imperialism and Colonialism, 1870–1914
1. Imperialism
Definition & Era
The “New Imperialism” (roughly 1870–1914) was faster, more global, and tied to industrial capitalism.
Timeframe
1870–1914, pre-World War I.
Motives
Economic: raw materials (rubber, oil, cotton, tin) and markets for goods.
Strategic: ports, naval bases, trade routes (e.g., Suez Canal).
National Prestige: colonies as symbols of greatness.
Social Darwinism: misapplication of Darwin to justify domination of “weaker” peoples.
Missionary Zeal: spread Christianity, Western education, and medicine; often tied to cultural imperialism.
Major Powers Involved
Britain, France, Germany, Belgium, Italy, Japan, the United States, and Russia.
By 1914, most of Africa, large parts of Asia, and the Pacific were under imperial control.
2. Imperialism in South Asia
British Raj
Britain’s direct control over India began after the Sepoy Rebellion of 1857, ending East India Company rule and placing India under the Crown.
Economic Impact
India became a major supplier of cotton, tea, jute, and opium; served as a market for British textiles.
Infrastructure
Railways, telegraphs, and ports expanded; benefited British control more than local populations.
Cultural Impact
English became the language of administration; Western education cultivated an Indian middle class.
Indian Nationalism
Emerged among Western-educated Indians seeking greater self-government.
Indian National Congress
Formed in 1885; initially reformist, later pushed for independence.
3. Imperialism in China
Decline of Qing Dynasty
Rebellions (Taiping 1850–1864) and defeats in the Opium Wars (1839–1842, 1856–1860) weakened Qing.
Treaty ports opened; Hong Kong ceded to Britain.
Spheres of Influence
Britain, France, Germany, Russia, and Japan carved out zones for exclusive trade and investment rights; China retained sovereignty but was economically dominated.

North Africa: Algeria (1830s), Tunisia (1881), Morocco (1912).
West/Central Africa: Senegal, Ivory Coast, Congo Basin.
Southeast Asia: French Indochina (Vietnam, Laos, Cambodia).
Mission Civilisatrice (Civilizing Mission)
France’s ideology to spread language, culture, and values; education, infrastructure, and legal systems imposed on colonies, often at local expense.
Critics viewed it as cultural imperialism disguised as benevolence.
5. The “Scramble for Africa” and the Congo
Berlin Conference (1884–1885) — European powers set rules for claiming African territory to avoid war among themselves.
No African representatives present.
By 1914, nearly all Africa was under European control except Ethiopia and Liberia.
Congo Free State
Personal domain of King Leopold II of Belgium (1885–1908); rubber exploitation caused millions of deaths; international outrage forced Belgium to take direct control.
6. Imperial Culture
Popular Support for Empire
Exhibitions, literature, school curricula glorified expansion; adventure novels romance imperial life (e.g., Kipling, King Solomon’s Mines).
Racial Ideologies
Pseudoscientific racism justified colonial rule; “White Man’s Burden” framed as civilizing mission.
Cultural Exchange
Colonies influenced European tastes in art, cuisine, and fashion (e.g., tea in Britain; African motifs).
7. Crises of Empire at the Turn of the Twentieth Century
Colonial Resistance
Armed uprisings: Mahdist War in Sudan (1881–1899), Ashanti resistance, Boer resistance in South Africa.
Intellectual and nationalist movements challenged imperial rule (e.g., Indian and Egyptian nationalists).

Environmental Changes
Introduction of European farming techniques, crops, and livestock altered ecosystems; deforestation and soil depletion in colonies.
Cultural Demographic Shifts
Settlers displaced Indigenous peoples, changing cultural landscapes.
9. Conclusion
From 1870 to 1914 imperialism peaked, reshaping global politics, economies, and cultures.
European dominance spanned continents but also sowed seeds of resistance and decolonization in the 20th century.
Imperial rivalries created new alliances and tensions, contributing directly to the outbreak of World War I.

After Bismarck’s dismissal (1890), German policy shifted, drawing France and Russia closer.
Naval Arms Race
Britain and Germany competed to build powerful fleets, elevating tensions.
Imperial Rivalries
Conflicts over Africa and Asia increased mistrust among powers.
9. Conclusion
By 1914, industrial power, mass politics, and imperialism were tightly interwoven.
Political participation expanded dramatically, but inequalities and rivalries created tension.
Ideologies such as socialism, feminism, and Zionism reflected reformist hopes, while racial theories and imperial competition pushed Europe toward global conflict.

Formation of NATO (1949)
North Atlantic Treaty Organization; military alliance of US, Canada, and Western European nations to deter Soviet aggression.
Warsaw Pact (1955)

4. The Korean War (1950–1953)
Causes
Korea divided at the 38th parallel after WWII; North (communist) backed by USSR/China; South (anti-communist) backed by US.
Course
Early North Korean advances; UN counteroffensive led by General MacArthur; Chinese intervention pushed UN forces back; stalemate ensued.
Outcome
Armistice in 1953; border near original line; underscored limits of containment and solidified Cold War divisions in Asia.
5. The Nuclear Arms Race and Space Race
Arms Race
US held nuclear monopoly initially; USSR tested an atomic bomb in 1949; hydrogen bombs (early 1950s) escalated destructive potential.
Doctrine of Mutually Assured Destruction (MAD).
Space Race
USSR launched Sputnik (1957); US responded with NASA (1958); Yuri Gagarin (1961) first human in space; Apollo 11 landed on the Moon (1969).
6. Decolonization and the Cold War
Global Context
Postwar weakening of European powers accelerated independence movements in Asia, Africa, and the Middle East; US and USSR competed for influence in new states.
Key Examples
India and Pakistan independence (1947).
African decolonization (late 1950s–1960s): Ghana (1957), Congo (1960), Algeria (1962).
Vietnam’s struggle for independence from France evolved into a Cold War battleground.
7. The Cuban Missile Crisis (1962)
Background
Castro’s 1959 revolution; Bay of Pigs (1961) failed attempt to overthrow him.
Crisis
Discovery of Soviet missiles in Cuba; US imposed a naval quarantine; Khrushchev agreed to withdraw missiles in exchange for US non-invasion pledge and secret removal of US missiles from Turkey.
Significance
Closest the Cold War came to nuclear war; led to improved direct communications (hotline) and intensified arms control talks.
8. Western Europe’s Economic Miracle
Reconstruction & Growth
Marshall Plan, economic integration, modernization.
Formation of the European Economic Community (EEC, 1957) promoting free trade.
Social Changes
Rising living standards, consumer goods, welfare states; expansion of higher education and cultural exchange.
9. The Civil Rights Movement in the United States
Origins and Goals
Aimed to end racial segregation/discrimination; secure voting rights and equality under the law.
Key Events
Brown v. Board of Education (1954) desegregated public schools.
Montgomery Bus Boycott (1955–1956) led by Martin Luther King Jr.
Civil Rights Act (1964) and Voting Rights Act (1965) outlawed segregation and discriminatory voting practices.
Impact
Inspired other social movements (women’s rights, anti-war movements).
10. The Vietnam War and Cold War Tensions
Background
After France’s defeat, Vietnam divided at the 17th parallel; Ho Chi Minh’s communist North vs US-backed South.
Course
Viet Cong guerrilla warfare; US bombing campaigns and troop deployments; widespread protests globally.
Impact
Deepened Cold War divisions; eroded trust in US government (credibility gap).
Paris Peace Accords (1973) led to US withdrawal; Saigon fell in 1975.
11. Conclusion
The early Cold War era reshaped global politics into a bipolar order.
Nuclear weapons, ideological rivalry, and decolonization defined international relations.
Domestic social change and economic growth transformed societies, but civil rights struggles, wars (e.g., Vietnam), and ideological contests produced lasting tensions into the 1970s and beyond.
