Grand Duchy of Rhineburg (New World Map Game)

Rhineburg, officially the Grand Duchy of Rhineburg (German: Großherzogtum Rheinsburg') is one of the two Grand Duchies in the United Reich of New Bayern. The dukedom is traditionally held by the first son (later first child regardless of gender) of the incumbent Kaiser. In the event that the Kaiser has no children, the dukedom will remain vacant until the Kaiser has issue, or upon the death of that Kaiser and the coronation of one with a child.
