>>4482The point of the whole question is to get some discussion going.
DID they actually justify themselves by being chosen by the gods? Considering the the origin of the word "King", in every Germanic language, it rather seems they justified themselves by being of noble ancestry, maybe even including the gods in it?
That would lead to the question how monarch would be chosen today. Some sources suggest they were elected, but how would that work out in a modern environment? I don't think we even know how long that position was valid.
