Greatest Obstacle to German Unification: Austria vs. Prussia Rivalry

The fundamental barrier to German unification was the dualism between Austria and Prussia — the two great German powers competing for hegemony over the German-speaking world.

The Core Conflict

• Austria: Multi-ethnic empire (Germans, Hungarians, Czechs, Poles, Italians, South Slavs); Habsburg dynasty; Catholic; conservative; looked to Balkans/Italy.
• Prussia: Predominantly German; Hohenzollern dynasty; Protestant; militarized; bureaucratic; focused on North Germany.

Both claimed leadership of "Germany" — but their visions were incompatible.

Key Milestones

• 1848–49 Revolutions: Frankfurt Parliament offered crown to Prussian king (refused); Austria suppressed Hungarian/Czech revolts; dualism intact.
• 1850 Olmütz: Prussia forced to abandon Erfurt Union by Austria/Russia — humiliation.
• 1866 Austro-Prussian War (Seven Weeks' War): Bismarck provoked conflict; Prussia's needle gun, rail logistics, Italian alliance crushed Austria at Königgrätz. Austria excluded from Germany; North German Confederation formed under Prussia.
• 1870–71 Franco-Prussian War: Southern states (Bavaria, Württemberg, Baden, Hesse) joined North German Confederation against France. January 18, 1871: German Empire proclaimed at Versailles — unification under Prussian leadership, Austria excluded.

Why Austria Lost

Overextended empire, nationalist revolts, diplomatic isolation (Russia alienated by Crimean War neutrality), and Bismarck's Realpolitik — exploiting nationalism to serve Prussian state interest.

The "German Question" was settled: Kleindeutschland (Germany without Austria) prevailed over Großdeutschland.
