How did Napoleon govern the European teritoriese conquered? To what extent was he successful

Nearly all of Europe fell under Napoleon's control, and certainly all of it was forever changed by being ruled by him or fighting against him. The Napoleonic period was an extremely complicated time. Moral right and wrong are hard to distinguish: Napoleon was a dictator, but not a particularly evil one. He encouraged many developments we today consider quite positive. The Napoleonic Wars were instigated by France, but each nation fought to protect and expand its own national interest.

Napoleon was in many ways very progressive, advancing many of the goals of the Revolution, and rationalizing government and social processes wherever he went. Napoleon represented change.
