A military and political leader. It’s debatable whether Napoleon is a hero or villain but regardless of your opinion on one of the world’s greatest military leaders of all time; he is certainly someone who has changed the world!

Why is Napoleon important in world history? Napoleon invaded, and lost, much of Europe during the Napoleonic Wars and oversaw a number of changes in society and in the law. In post-revolution France, his code set the first firm laws for property, families and individual rights. He made many innovations in warfare and also created the metric system.
