A constitution is a statement of the basic principles and laws of a nation, state, or group, such as the U.S. Constitution. Another very common meaning of constitution is the physical makeup of a person. So think of a constitution as how a body (yours, the government's) is set up. If you have a strong constitution, it means you don't get sick very often.
I think the focus of the story is on Beowulf as a hero rather than a king because it is his heroic deeds that lead to him being offered the throne. Also to be king one must possess some type of heroic qualities in order to rule a land and its people.
There is more than one king in Beowulf. The King of the Danes is Hrothgar: Hrothgar is a good king. He lives in the Kingdom that Grendel is terrorizing. He is noble, but is unâ¦able to fight. Therefore he calls Beowulf, to whom he is a father figure. He is the symbol of what type of king Beowulf becomes.
