Italian historiography reflects a great deal of propaganda, especially for things that took place from around 1860 to around 1950.
Frankly, most Italians still don't have a strong position on their families' involvement with Fascism, if they even know much about that sordid chapter of Italian history, so to presume much knowledge of the 19th century might be presuming too much from most people raised in this charming country.
Though fictional, this book has a lot to say about revisionism, and it's an interesting read.
