His dad. His uncle was so upset about it because he thought it belonged to him and not to his brother or nephew.
He got so mad that he set up a ploy to kill his brother and take possession of it. His plan worked. He killed his brother and took over the land. The son(his nephew) went crazy for a while because of his dad’s death. Went and hung out with some flamboyant low life friends for a while and didn’t make much of his life.
But then the son came back to his senses and realized the inheritance belonged to him. He saw his uncle was making a mess of it, so he went back and fought his uncle. Ended up killing him. Then he took over the inheritance and things worked out really well for him. Married a smokin hot wife, and became the king of a large kingdom.
But I guess that’s not that crazy…
