Seems fine.

But I noticed you didn't add much this time around. You're free to make up the history of your nation from 1914 onwards. The summaries are basically a listing of things that are canon, and that should be acknowledged when you make an application for a country. But that doesn't mean you can't make up events and add them to the story of your nation.

But if you just decided to keep it short, that's fine too.
