1815: A Pivotal Year — Congress of Vienna, Waterloo, and a New European Order

1815 reshaped the geopolitical map of Europe and the Atlantic world through five landmark events:

1. Congress of Vienna (Sep 1814 – Jun 1815)

• Diplomatic summit of victorious powers (Austria, Britain, Prussia, Russia, later France).
• Goals: Restore legitimate monarchies, balance power, contain France, suppress revolution.
• Outcome: Redrawn borders (Poland partitioned, Netherlands created, German Confederation formed), Concert of Europe system for dispute resolution. Dominated 19th-century diplomacy.

2. Battle of Waterloo (June 18, 1815)

• Napoleon's "Hundred Days" return ended by Wellington (Anglo-Allied) & Blücher (Prussian).
• Napoleon abdicated → exiled to St. Helena; Bourbon Restoration (Louis XVIII) in France.
• Symbolic end of revolutionary/Napoleonic era.

3. British Corn Law (1815)

• Tariff on imported grain to protect landowners.
• Raised bread prices → urban unrest; catalyzed free-trade movement (Anti-Corn Law League).
• Repealed 1846 (Peel) — landmark for liberal economics.

4. War of 1812 Ends (Treaty of Ghent, Feb 17, 1815)

• US–Britain stalemate; status quo ante bellum.
• Boosted US nationalism; ended Native American resistance in Old Northwest (Tecumseh's death 1813).
• Laid groundwork for Rush-Bagot (1817) demilitarizing Great Lakes.

5. German Confederation Founded (June 1815)

• 39 states (Austria, Prussia, Bavaria, etc.) replacing Holy Roman Empire (dissolved 1806).
• Weak diet at Frankfurt; Austria presided. Precursor to 1871 unification.

Legacy

1815 established the "Concert of Europe" — a century of relative great-power peace (until 1914), conservative order, and the framework for German/Italian unification.
