The Continental Blockade (French: Blocus continental), or Continental System, was the foreign policy of Napoleon Bonaparte against the British Empire during the Napoleonic Wars. As a response to the naval blockade of the French coasts enacted by the British government on 16 May 1806, Napoleon issued the Berlin Decree on 21 November 1806, which brought into effect a large-scale embargo against British trade.[1][2] The embargo was applied intermittently, ending on 11 April 1814 after Napoleon's first abdication. The blockade did not cause significant economic damage to the British, although British exports to the continent (as a proportion of the country’s total trade) dropped from 55% to 25% between 1802 and 1806.[3] As Napoleon realized that extensive trade was going through Spain and Russia, he invaded those two countries.
The episode seriously hurt France itself. Shipbuilding, and its trades such as rope-making, declined, as did many other industries that relied on overseas markets, such as the linen industries. With few exports and lost profits, many industries were closed down. Southern France, especially the port cities of Marseille and Bordeaux, as well as the city of La Rochelle, suffered from the reduction in trade. Moreover, the prices of staple foods rose in most of continental Europe. [18]
