Congress of Vienna (1815): Goals, Outcomes, and the Century of Peace

After Napoleon's defeat, the victorious powers—Austria, Britain, Prussia, Russia, France—met in Vienna to redraw Europe's map and build a durable peace. Their goals were threefold.

1. Balance of Power

No single state should dominate. Solutions:

• Strengthen states around France: Netherlands (new Kingdom), Prussia (Rhineland/Westphalia), Sardinia-Piedmont (Genoa).
• German Confederation (39 states) replaces Holy Roman Empire—Austria presides, Prussia co-leads.
• Poland partitioned again (Russia gets most; Austria, Prussia get shares).

2. Legitimacy & Containment of Revolution

Restore pre-1789 monarchies where possible:

• Bourbons in France (Louis XVIII), Spain, Naples.
• Papal States restored.
• Swiss neutrality guaranteed.
• France penalized: 1790 borders, 700M franc indemnity, occupation army 5 years.

3. Collective Security: The Concert of Europe

Regular congresses (Aix-la-Chapelle 1818, Troppau 1820, Laibach 1821, Verona 1822) to manage crises. Principles: intervention against revolution (Troppau Protocol), great-power consensus.

Results

Successes: No general European war 1815–1914 (99 years). Revolutionary waves (1820, 1830, 1848) contained. Belgium independence (1830) managed peacefully. Greek independence (1830) negotiated.

Failures/Flaws: Ignored nationalism, liberalism. Polish, Italian, German unification suppressed. Ottoman decline unmanaged. Concert collapsed over Crimea (1853) and Italian unification (1859).

Legacy

Realist diplomacy template. "Vienna System" = great-power management of status quo. Worked while powers accepted it; failed when revisionists (Napoleon III, Bismarck, later Hitler) rejected the rules. The map held until 1914—remarkable for Europe.
