Even at the risk of being called again a nitpicker:
Germany became into existence in 1871. And before, it wasn't only Prussia - Bavaria, Hannover, the various Hessian countries etc weren't different at all.
As an aside: in the 11th century, a local earl had had his territory up to the North Sea ...
... until he died childless. (That territory later became more than a dozen independent countries.)
Such kind of "imperialism" was common during the medieval time, and later, of course, too.
