It isn't really shortly though. There's still over a decade from the end of the manga to the start of WWI, and the late 1800s to early 1900s is a popular era to set (western) romantic period fiction because it's peaceful, prosperous, and not as chaotic/dirty as it was early in the industrial revolution.

It's a lot different from the looming threat of Russia in Otoyo.
