Conquests

Napoleon conquered the north of Italy, and actually Netherlands and Belgium. Actual countrie of Spain, The confederation of the Rhine, The Kingdom of Naples and Grand Duchy of Warsaw, were states under the French influence. Austria, Hungary, Prussia, the Kingdom of Norway and Denmark were states allied to France. He tried to conquer England by blocking his trade routes creating an economical war, but he was defeated by Commander Nelson.  To summarize, by 1812 Napoleon controlled much of Europe but he wanted to rule Russia as well. He invaded Russia and marched to Moscow but his freezing, starving armies were forced into a disastrous retreat in 1812. That was the beginning of the end of his power.
