Napoleon the Little Book

I don't like politics, avoid everything that has to do with government structures, and I don't care about royal families so picking up a book on the subject felt difficult, and it took me several months to get through so much dense, tightly-packed information...But you know what? I learned so much about history in general that I'll never forget, and I can apply to any writing project I choose. Sometimes it's worth it to go outside of your comfort zone and chew on a difficult book. I recommend this if only to see the sheer depth of information is actually available from historical records, it's incredible.

It's highly academic writing so it's best read a little bit at a time. I use it as a reference frequently for my worldbuilding project based on Paris in 1190 AD.
