The Berlin Decree
was issued by Napoleon
on November 21
, following the French success against Prussia at the battle of Jena
. The decree forbade the import of British
goods into European countries allied with or dependent upon France, and installed the Continental System
It eventually led to economic ruin for France, while little happened to the economy of Britain, who had control of the Atlantic Ocean trade. Other European nations removed themselves from the continental system, which, in part, led to the downfall of Napoleon Bonaparte.
