Answer 1

One outcome of the Continental System that Napoleon put in place was that it led to the French invasion of Russia. The Continental System aimed to weaken Britain economically by prohibiting trade with British goods; however, it ultimately strained relations between France and Russia, contributing to Napoleon's decision to invade Russia in 1812 when Tsar Alexander I withdrew from the System.
