I've been eyeing the Pokemon/Nobanunga's Ambition crossover game, and I've recently become curious about is that despite its fairly well-developed mythology, the Pokemon series has a significant lack of information about the history of its world. There is little mention of famous kings, of empires, of foreign influence, etc. Sure, there is some (Lucario and the Mystery of Mew, the books in the various libraries), but it is sparse and vague.
So, for game developers, fan fiction writers, role-players, and curious minds alike, I would like to pose a few questions that my readers can examine. For the record, we will assume that the Pokemon world is, in fact, Earth (the numerous fourth wall references suggest this), in our "real" timeline.
1. How did the Pokemon nation as we know it begin? Was it a loose confederation of isolated tribes, like that of the Native Americans? Was it a collective of warring city-states, like ancient Greece? Were there every any major empires? Was there ever any attempt at unification?
2. Foreigners definitely "discovered" the Pokemon world at one point or another, but when and how? Was it merely a brief stopping-point, or was it part of a colonial empire? And given the obvious Japanese architecture and culture, how/when/to what extent did Japan influence the Pokemon world? Did the isolationist shogunate affect the Pokemon world?
3. Taking it further in history, was the Pokemon world ever involved in an international war, like the World Wars? Did it ever experience a revolution against a colonial power? Was it ever involved in the Cold War, on either the communist or democratic sides?
4. Where does its amazing technology come from? Has it experienced a technological singularity? Does the rest of the world have this technology?
And, of course, feel free to add your own. Think about these things, and feel free to add your views and insight.
