IBDP History HL Paper 3 -Europe and the First World War (1871–1923) - Study Notes- New Syllabus

Maintenance of peace and stability, and the changing balance of power in Europe (after 1871)

📝 Introduction

• After 1871 leaders sought to avoid a general European war while competing over colonies and Ottoman lands.
• A balance among great powers was repeatedly renegotiated through congresses and alliances.
• The relative peace before 1914 coexisted with recurring crises.

🌍 Empire and the Balkans

Imperial expansion sharpened diplomatic rivalries but also provided occasions to bargain. Balkan nationalism and Ottoman retreat brought Russia and Austria-Hungary into competition. At the Congress of Berlin in 1878, Bismarck mediated revisions to the Treaty of San Stefano; Bulgaria was reduced, Austria-Hungary received the right to occupy Bosnia-Herzegovina, and several Balkan states gained recognized independence. The settlement checked Russian influence but left nationalist ambitions unresolved.

The Ottoman Empire remained a significant actor despite territorial decline. Calling it merely an empty space overlooks its government, soldiers and inhabitants.

🤝 Bismarck’s Alliances (1871–1890)

Bismarck sought to protect the newly united empire and isolate France. The Dual Alliance with Austria-Hungary (1879), Triple Alliance including Italy (1882) and Reinsurance Treaty with Russia (1887) formed overlapping safeguards. Maintaining links with both Austria and Russia was difficult because their Balkan aims differed.

The system helped avoid a major war under Bismarck, but depended on careful diplomatic management and on partners whose interests could diverge. It was neither a permanent guarantee of peace nor a direct blueprint for the alliances of 1914.

⚖️ Historical Assessment

Congress diplomacy and alliance bargaining reduced some short-term dangers, while colonial competition and Ottoman decline generated fresh disputes. Weigh the achievement of no general great-power war from 1871 to 1914 against the instability created by Balkan rivalry and increasingly rigid expectations of support.

⚡ Quick Recap
✔ Imperial and Balkan disputes changed diplomatic calculations.
✔ Berlin’s settlement did not resolve nationalist claims.
✔ Bismarck built overlapping alliances to protect Germany.
✔ Peace required continual negotiation.

Causes and impact of German foreign policy before the First World War

📝 Introduction

• Germany’s foreign policy changed when Wilhelm II sought a more visible global role.
• Domestic pressure, elite ambition and fears about security interacted.
• The reactions of other powers matter as much as Berlin’s intentions.

👑 Wilhelm II and Weltpolitik

After Bismarck’s dismissal in 1890, Germany did not renew its Reinsurance Treaty with Russia. Wilhelm II promoted Weltpolitik, naval building and colonial ambition, appealing to some industrial, military and nationalist interests. The 1898 and 1900 naval laws expanded a fleet capable of challenging British maritime security. Imperial posturing offered prestige but exposed Germany to competition with established powers.

The emperor influenced policy strongly, although ministers, admirals and interest groups also shaped decisions. Domestic unrest cannot by itself explain every international crisis.

🌐 Responses Abroad

Britain strengthened ties with France through the Entente Cordiale of 1904 and reached an understanding with Russia in 1907, though these arrangements were not identical to a binding three-way military alliance. Germany’s challenges to French interests during the Moroccan crises of 1905–1906 and 1911 increased French and British concern. Austria-Hungary remained Germany’s crucial partner, tying Berlin more closely to Balkan disputes.

Russia developed French financial and military ties after the treaty lapse. German leaders feared encirclement, yet their own naval and diplomatic choices contributed to other states’ anxieties. Trace this two-way escalation rather than attributing every move to one country.

⚖️ Historical Assessment

Wilhelm II’s policies contributed substantially to a more polarized Europe, especially through naval rivalry and confrontations over Morocco. Yet foreign alliances were also responses to separate colonial, strategic and Balkan interests. Distinguish changes in German aims from the unintended diplomatic costs of how those aims were pursued.

⚡ Quick Recap
✔ Weltpolitik combined prestige, empire and naval expansion.
✔ Wilhelm II operated within domestic and diplomatic pressures.
✔ Britain, France and Russia drew closer.
✔ Austria-Hungary’s alliance pulled Germany toward Balkan risks.

Reasons for the First World War

📝 Introduction

• The assassination at Sarajevo began a July 1914 crisis within a much longer history of rivalry.
• Explain why a local Austro-Serbian conflict escalated into a general European war.
• Alliances shaped decisions, but leaders still made choices.

🔥 Balkans, Crises and Arms

Austria-Hungary feared Serbian nationalism and further loss of control over its diverse empire; Russia presented itself as a protector of Serbia and pursued Balkan influence. The annexation of Bosnia-Herzegovina in 1908 and Balkan Wars of 1912–1913 sharpened tensions. Rival army plans and the Anglo-German naval race increased mistrust and encouraged rapid mobilization, although spending on weapons did not automatically cause war.

Earlier Moroccan crises had also tested cooperation and hardened expectations. Their significance lies in how governments read each other’s intentions by 1914.

📅 Sarajevo and the July Crisis

After the assassination of Archduke Franz Ferdinand on 28 June 1914, Germany promised support to Austria-Hungary. Vienna issued a severe ultimatum and declared war on Serbia. Russian mobilization, German declarations of war on Russia and France, and the German invasion of neutral Belgium brought Britain into the war in early August.

The Triple Alliance and Franco-Russian alliance mattered, but Italy did not enter on Germany’s side in 1914. Analyse the precise decisions and fears of the July Crisis rather than claiming treaty signatures made war inevitable.

⚖️ Historical Assessment

Balkan nationalism and imperial insecurity generated the immediate Austro-Serbian clash; alliance obligations, mobilization plans and mutual suspicion widened it. A convincing explanation weighs long-term rivalries against the contingent decisions of Austria-Hungary, Germany, Russia, France and Britain in July and August 1914.

⚡ Quick Recap
✔ Balkan competition created an immediate flashpoint.
✔ Arms plans and earlier crises magnified mistrust.
✔ The July decisions escalated a local war.
✔ Italy did not join the Central Powers in 1914.

Reasons for the defeat of Germany and the other Central Powers

📝 Introduction

• Defeat resulted from cumulative losses, strained economies and the Allies’ growing resources.
• Compare strategy and technology with events on the home fronts.
• US entry mattered, especially by 1918, but cannot erase the contribution of existing Allies.

⚔️ Strategy and Industrial War

Germany failed to secure a quick Western victory in 1914 and faced a prolonged two-front struggle. Artillery, machine guns, defensive positions, submarines and eventually tanks and aircraft raised the cost of fighting. British naval blockade strained German access to supplies; unrestricted submarine warfare failed to force Britain out and helped trigger US entry in 1917.

The 1918 German spring offensives initially gained ground but could not sustain the advance. Allied coordination under Foch, the Hundred Days attacks and worsening German manpower turned the military balance decisively.

🏭 Resources, America and Morale

Allied states drew on larger combined resources and imperial networks. US loans and supplies were important before 1917, while American troops arrived in increasing numbers in 1918. After Russia’s withdrawal Germany briefly shifted forces west, yet its allies Austria-Hungary, Bulgaria and the Ottoman Empire were also exhausted.

Food shortages, inflation, casualties and fatigue eroded civilian and military morale. Protest and political change on Central Powers’ home fronts in 1918 accelerated collapse; these domestic pressures were connected to, not separate from, military setbacks.

⚖️ Historical Assessment

Allied material superiority and US support became most decisive when Germany’s final offensives failed in 1918. Blockade and home-front hardship weakened endurance, while effective Allied counterattack ended any realistic prospect of victory. Rank causes by timing: American participation increased the margin, but Central Powers had already suffered years of attrition.

⚡ Quick Recap
✔ A quick German victory failed in 1914.
✔ Blockade, attrition and hardship weakened endurance.
✔ US resources and troops strengthened the Allies.
✔ The failed 1918 offensives preceded collapse.

Impact of the First World War on one European country (to 1923)

📝 Introduction

• Germany shows how battlefield defeat, blockade and revolution affected ordinary lives.
• Trace changes through the Weimar Republic’s early years, ending in 1923.
• Describe distinct experiences of women, workers, veterans and excluded groups.

👥 Social Life and Women in Germany

Mass deaths and injuries left bereaved families, disabled veterans and social conflict. Food shortages during the war harmed health, especially among poorer urban households. Women entered some jobs and welfare roles vacated by men, yet post-war demobilization and gender expectations limited the permanence of those opportunities. Women gained national voting rights in 1918 and voted in 1919, a major political change that did not produce equal wages or leadership.

The 1918–1919 revolution ended the monarchy and made social and political reform possible, but fears of violence polarized communities.

💸 Economy and Marginalized Groups

War borrowing, reparations disputes, dislocation and the loss of productive resources burdened the new republic. Hyperinflation in 1923 destroyed many savings, though some debtors benefited; distinguish this crisis from wartime inflation. Veterans and workers competed for limited support. Jewish Germans and other minorities faced scapegoating and antisemitic propaganda, even though legal citizenship persisted.

Regional differences mattered, and experiences cannot be reduced to a single national level of hardship. Political instability in 1923, including the Ruhr occupation, intensified the crisis.

⚖️ Historical Assessment

Germany’s war transformed government and women’s formal political rights while creating lasting human and fiscal costs. Link the 1923 inflation to post-war policy choices and reparations conflict as well as the war, and avoid assuming that all Germans or all women experienced the same consequences.

⚡ Quick Recap
✔ Use Germany as the single national case.
✔ War deaths and shortages reshaped families.
✔ Women gained suffrage in 1918 but unequal conditions persisted.
✔ 1923 inflation and scapegoating deepened post-war division.

Impact of the Paris Peace Treaties (1919–1923)

📝 Introduction

• The peacemakers sought security, self-determination and a stable settlement, but those aims conflicted.
• Treat each treaty as part of a settlement applied to different defeated states.
• Consider the different reactions of victors, defeated governments and national minorities.

🤝 The Big Three and Versailles

Wilson promoted a League of Nations and principles of self-determination; Clemenceau prioritized French security; Lloyd George sought an acceptable settlement protecting British interests. Versailles (1919) assigned Germany territorial losses, military limits, reparations obligations and responsibility under Article 231. Disputes about how much Germany should pay continued after the conference.

German critics attacked the imposed treaty. French fears about another invasion persisted; the new borders also left minorities under states in which they did not always wish to live.

🗺️ Other Settlements and Their Effects

Saint-Germain (1919) addressed Austria and formally barred union with Germany without League consent. Neuilly (1919) dealt with Bulgaria; Trianon (1920) redrew Hungary’s borders, leaving many ethnic Hungarians beyond them. Sèvres (1920) proposed severe terms for the Ottoman Empire, but Turkish national resistance led to Lausanne (1923), which recognized new frontiers and replaced much of the earlier settlement.

New successor states, border disputes, debt and inflation complicated recovery. By 1923 the French-Belgian occupation of the Ruhr illustrated the difficulty of enforcing reparations; Lausanne showed that organized resistance could force renegotiation.

⚖️ Historical Assessment

The treaties established borders and a framework for collective diplomacy but left conflicts over enforcement, minority rights and national identity. Explain specific terms before judging them: the German settlement was neither identical to Trianon nor to the superseded Ottoman arrangement. Outcomes up to 1923 varied by country and the willingness of major powers to compromise.

⚡ Quick Recap
✔ The Big Three differed over punishment, security and self-determination.
✔ Six named treaties covered distinct defeated powers.
✔ The peace redrew borders and generated minority disputes.
✔ Ruhr occupation and Lausanne revealed limits to enforcement.
