So how is 19th century imperialism different from Roman imperial expansion or Greek colonialism in antiquity for example? Or the various attempts to resurrect the Roman Empire by basically everyone? Why don’t we call Roman emperors or Alexander the Great or even Sigismund imperialists? Honest question here, I’m not a historian or anything.
You should read up on the EU then, I think you’d like it here.
It is far from perfect, but it works much better than anything else this size.
