Continental System (Napoleon's Economic War)
The Continental System (1806–1814) was Napoleon's attempt to defeat Britain economically by prohibiting European states under French control from trading with Britain, intending to cause British economic collapse through export market denial, which instead accelerated smuggling, damaged French-allied European economies (including France itself), forced Napoleon to expand his empire to enforce compliance, and contributed directly to the catastrophic Spanish and Russian campaigns that destroyed the Grande Armée.
After Trafalgar (1805) destroyed any French hope of invading Britain directly, Napoleon turned to economic warfare. The Berlin Decree (November 1806) declared Britain in a state of blockade and prohibited all trade between British territory and French-controlled Europe. Britain responded with the Orders in Council (1807), blockading Napoleonic Europe. The result was a global commercial war overlaid on the military conflict.
The Continental System's logic was correct in theory: Britain was the financial engine of every coalition against France, and denying it export markets would cause the commercial crisis that would force peace. The practice failed because the system required hermetic enforcement across a continent with 8,000 miles of coastline, multiple independent powers with economic incentives to cheat, and commodity markets that routed British goods through neutral intermediaries. The British used Portugal (one of the few European powers that refused to join the system) as a commercial backdoor, which is part of why Napoleon invaded the Iberian Peninsula in 1807, beginning the Peninsular War that tied down 300,000 French troops for six years.
The Russian dimension: Tsar Alexander I agreed to join the Continental System at Tilsit (1807) but found it economically devastating for Russian grain exports. Russian compliance deteriorated steadily, and by 1810 Russia was effectively ignoring the blockade. Napoleon's response, the catastrophic invasion of Russia in 1812, was an attempt to enforce Continental System compliance. The system that was supposed to strangle Britain instead strangled Napoleon's strategic judgment. The attempt to enforce an economically irrational policy at gunpoint is the classic overextension that predictive analysis of empire identifies as the mechanism of decline.

What was Napoleon's Continental System? ＋
Napoleon's 1806 embargo prohibiting European states under French control from trading with Britain, intended to cause British economic collapse. Failed because: impossible to enforce across Europe's coastline, smuggling proliferated, European allies cheated, and enforcement logic drove Napoleon into the Peninsula (Peninsular War) and Russia (1812 campaign). The system meant to strangle Britain instead destroyed the Grande Armée by forcing the overextension that doomed Napoleon's empire.
