Interesting, But in France napoleon is not systematically seen as a national hero. What is bothering me is that you show only the positive side of Napoleon .
First, it is maybe "a details", as would say Jean Marie Le Pen (FN), but behind his megalomany, and his dream of a great French Europe, there are millions of deads.
**Louisiana**
France was losing the war against English empire in North America and therefore, couln't afford to keep Louisiana. (I don't think the boundaries on your map (see link), was an English document..., whatever)
They did the best to find an ally amongs native american. So, the best we could say, Napoleon was a good businessman, to sell Louisiana for 1 millions francs.
**sciences and art**
They were progresses in sciences and art, but it is dodgy to relate it the reign of Napoleon.
**Poland**
I wished a Polish participant would give his opinion. I went to Poland once, and there, polish people made me understand Napoleon was seen as a "butcher".
**Napoleonic code**
My knowledge on this topic, is fairly limited, but it is actually seen as a positive contribution given by the napoleon's reign.
