I find this interesting, considering that non-magical Italy didn't exist as a unified nation until 1861. It seems odd that the magical political map so closely mirrors the non-magical.
He may be referring to a subarea that was roughly what is modern day Italy. Out of universe what is there's a more likely set of explanations: Transylvania is a natural spooky/magical thing (hence Rowling's decision to include it as separate), and Eliezer doesn't know much history, so things like the unification of Italy aren't on his radar screen.
Eliezer not knowing stuff is generally low on my list of possibilities. Italian unification isn't terribly obscure. And Italy was always a unified geographic and cultural area, even in the period where it was politically disjoint.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 95. The previous thread has passed 300 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24.
