A diary earlier dealt with this in part
The Roman Empire: Gentle folks, never hurt anyone.
The Byzantine Empire: Kept Up the Roman tradition of non conquest and peace.
The Holy Roman Empire: Such gentle people and inquisitive.
The Spanish Empire: Never tried to convert anyone.
Napoleon: Only wanted to help
The British Empire: Jolly good Chaps all round.
The East India Company: The business model of the future
The thirty years war: Just sorting out some points with respect to theology {corrected I sometimes mix up my carnages]
The colonization of America: Not one shot was fired, nobody wanted it.
World war one: A minor disagreement between friends
World war two: well one world war on its own was lonely.
The global slave trade: Insourcing that caused a minor kurfuffle when it was deemed to be a bit iffy.
Apartheid/Segregation: just some minor social organization to avoid potential misunderstandings.
The cold war: Planet management and organization.
The American Empire: Just doing the rounds and keeping everyone safe
The Corporations: Bringing great stuff to all.
Look we never hurt anyone ever,and never tried to make people do stuff they didn't want to, we only did it for the good of the natives..
Oh wait
Ooops
I wonder what Muslims were thinking about us as we desperately tried to eradicate anyone that got in our way.
