Actually, there were a few dreamers in Germany, but the majority wanted peace.
But it was not that Napoleon created Germany. He created a resurgence of German nationalism, but we have been here as a country since 962 AD 😀 It was just that the First Reich, as it was called, had become moribund in the latter half of the 18th century, so it eventually fell prey to the French invader (a long story, but this is how it ended).
A lot of people think that “Deutschland Uber Alles” expressed a desire for Germany to rule the world.
The phrase was an appeal to German monarchs to prioritize the creation of a united Germany over the independence of their small states.
