What was the main year range during which the Continental System was enforced?

The Continental System was primarily enforced from 1806 to 1812 as a French economic strategy aimed at weakening Britain by prohibiting trade between Britain and continental Europe. Napoleon I instituted this blockade in November 1806, intending to undermine Britain's economy, which was heavily reliant on trade. The enforcement continued until 1812 when the system began to unravel due to various factors, including widespread smuggling, resistance from various countries, and the growing need for European nations to engage in trade with Britain.

This timeframe is crucial as it reflects the diplomatic and military tensions of the Napoleonic Wars, showcasing the economic impact of military ambitions. The effectiveness and eventual failure of the Continental System also offer insight into the complexities of economic warfare and its influence on international relations during that period. The other time ranges listed do not align with the actual historical enforcement period of the Continental System, making this option the most accurate representation of that era.
