The Concordat of 1801 assured the Pope that most of France was Catholic. The Napoleonic code was enlightened in that it enforced universal male suffrage. The Continental System was an embargo of all British goods, and it was aimed at Britain. The 3 parts of Napoleon's empire were Spain, the Confederation of the Rhine, and the Grand Duchy of Warsaw. In the Peninsular War, France invaded Spain for violating the Continental System. Spain fought back using guerrilla warfare. At about the same time, Napoleon sent half of his army into Russia because they also defied the Continental system. Most of his troops froze to death, so it didn't go well. After that, Napoleon was forced to resign and was exiled to Elba. He returned to France for the Hundred Days and everyone welcomed him. Unfortunately, he lost the Battle of Waterloo and was exiled again to St. Helena, where he eventually died.
