Napoleonic wars for England, France, German states and Italy Reasons for how the wars affected these countries, etc.

The Napoleonic Wars were very influential. After all, they affected every country in Europe. Territories passed to one side, then to the other. Also, a lot of people died. The power in countries has changed, and the attitude in global politics has also changed. Many territories have fallen into desolation due to hostilities. Many countries were exhausted, both financially and physically. How much the state of affairs in Europe has changed, of course, is reflected in the Vienna Congress of 1814-1815. In those years, there was a large redistribution of territories, some states could return the lost territories, others get new ones.
