Ah I remember that. It was a good nod to the wars that happened between the Daiymo in Japan's shogunate period. It added a depth that despite being a different world, humanity was still the same old humanity.Reminds me of that medieval war in Lucario and the Mystery of Mew which has sort of stuck with me as an interesting piece of lore (actual war? In non-modern times?) but that was apparently in Kanto.
