How extensive do applications need to be? Should we have descriptions of ours leaders and long explanations of national history, or just a name and a short synopsis?

You don't have to go beyond a name for your leader. But a few paragraphs for your nation's history are ideal. You can make up the post-Great War history (like how your leader came to be) for your nation as long as it doesn't contradict whatever is in the summaries.
