What is required for one to call oneself King? Who where the first Kings that we know about? Are there different kind of Kings?
This is obviously a powerful image that has existed for a long time. Everybody knows how a King looks like with the golden crown and red cape and everything but where did that come from?
I'm also wondering what the definition of King is and how this concept became to be.
This question is a vast, one and would differ depending on the era and the kingdom. Also are you just referring to men who bore the title of King, or all monarchs across the globe, who wouldn't be called King, but would have different titles for their monarchs depending on the culture (like the Sapa Inca, or the Brak)?
