Basic mindmap diagramming interpretations of where power lay in the Second Reich (lacks specific detail)

I read a book which recommended that mindmaps should never contain specific detail, instead every piece of information should be limited to one word which I've tried to do here (I failed once or twice!!). This all means that the diagram is simple, and is intended to jog your memory, rather than provide all of the information! I'm going to use it to test my memory to remember the events which back up their individual interpretations (i.e. Hottentott Election...)
