Reply Japan has not experienced a dynastic change in over 2500 years. Emperors were not deposed but their temporal power was marginalized during the ascendance of the Shogunate.
True enough but as I understand it the Emperor served as the figure head above the fray between the factions, power itself rested beyond the person sitting on the throne and despite the dynasty stretching back in time I believe the bodies changed rather easily, as even the seat could be moved if desired, hence the capital ends up in Toyko. I agree in any event, the thrust is that Japan is very different in its infighting where Germany wrestled instead with the distribution of power between the States led by its biggest, Prussia. Japanese democracy served to represent the old factions beneath the Emperor, these being essentially the families who had re-ordered Japan and put a new polish on the otherwise weak and disused Emperor, whereas German democracy has its root in the 1848 revolt and the unification, limiting the Monarch. The power struggles stem from different places to serve up Japan as a guide to how German democracy fails.
