Really? What are they?
His biggest impact was on France.
Post-War Stagnation: Prolonged warfare during the Napoleonic period resulted in significant casualties among young French men, (estimated between 600,000 to 1.2 million) causing France's population growth to slow considerably compared to neighbors like Britain and Germany over the rest of the 19th century.
IMHO, Napoleon was a disaster for France and Europe in general.
Within the German Confederation, many of the borders he had drawn for the different German states persisted until the Hitler era, when the states were de facto suppressed.
Still, many of the borders of Europe were redrawn in Vienna in 1815, but others were confirmed 🙂
And I absolutely agree: the loss of life was utterly devastating to France, and in my opinion, this is what caused the country to lose its predominance in Europe, which she had held since 1648/59.
Millions more died on the other sides: Russians, Britons, Germans, Poles, Hungarians…in Germany, there was a saying that Napoleon planted a weeping willow before nearly every German house😔 - this tree being a sign of mourning.
